Definitions
- the invention relates on the one hand to a method for determining at least one parameter of a molten metal by means of a measuring device for generating measurement data of these parameters and to a processing device arranged outside the molten metal for processing this measurement data, the measuring device being introduced into the molten metal, and on the other hand to a device for carrying out this method and finally an associated measuring device.
- Thermocouples, optical or pyrometric measuring devices permanently installed on the converter vessel are proposed from various sides. Such measuring devices are subject to high wear due to the permanently very high temperature load and falling "boiler bears".
- Blow lances with built-in pyrometers are used to measure the temperature without contact during blowing.
- such measuring devices are not suitable for evaluating samples and for measuring the oxygen content.
- two generic methods and devices for their implementation are known which use generic measuring devices for determining parameters of a molten metal.
- the measuring devices are either thrown into the molten metal as a so-called “immersion body” from a discharge station, or are introduced into the molten metal using a lance.
- the measuring device is connected to a cable Processing device for processing the measurement data connected.
- data are processed - for example statistically -, used to control or regulate the steel manufacturing process, fed online into a parallel numerical simulation or displayed in the form of characteristic values.
- US Pat. No. 3,374,122 describes an immersion body: On the one hand, it is proposed to specifically increase the weight of the measuring device by means of additionally integrated masses, so that the measuring device reliably penetrates the slag layer under its own weight, and on the other hand to equip the measuring device with tines projecting downwards in order to provide one To prevent damage to the thermocouple, which also protrudes, on impact with the slag surface.
- a buoyant immersion body is described in US Pat. No. 4,881,824: an elongated rod-shaped probe, in particular for introducing a sampling body into a metal melt, is weighted on the one hand by a thickened steel tube at the lower end and on the other hand surrounded by a cardboard sleeve as a buoyancy body at the upper end.
- the weighting and the buoyancy body are adapted to the known density of the molten metal - and thus to the known buoyancy forces - in such a way that the immersion body penetrates a slag layer formed on the surface of the molten metal, with its swollen end into the molten metal into one immerses defined depth and is held in a vertical position by the floating body in the molten metal floating.
- the cable of such an immersion body remains connected to the ejection station above the converter during the measurement, the data is forwarded from the ejection station to the processing device for processing the measurement data.
- a release station is described, for example, in US Pat. No. 5,610,346:
- a special coordination of the suspension of a plurality of immersion bodies and the fastening of their cables in the release station and a device for separating the cable ends remaining after each measurement are proposed.
- the cable burns in the converter.
- the remaining cable end is cut off in the ejection station and falls into the converter, where it also burns.
- the connecting cable to the processing device remains an essential weak point of the system:
- the cable end remaining in the ejection station must be reliably cut off after the measurement and in particular removed from the ejection path, since otherwise it can block the subsequent immersion body. If an admission device is used as a discharge path, this can be blocked overall.
- measuring head a so-called “measuring head” - into the molten metal at the tip of a lance from the casting platform.
- the measuring head and the lance end are surrounded by a cardboard sleeve that protects both components from the heat of the molten metal and from metal splashes.
- the measuring head is usually destroyed by the measurement and, after a single use, is discarded together with the cardboard sleeve.
- the manual feeding of a measuring head by means of a lance is a very simple generic method, but has a number of decisive disadvantages - especially in mass production:
- the accuracy of the measurement depends largely on the level of training of the operator. - If the lance is immersed in the molten metal, escaping metal splashes endanger the health of the operator.
- the converter process must be interrupted for the duration of the measurement in order to be able to move the converter into a position inclined to the casting platform.
- Japanese patent application JP 2000028438 describes a device for measuring temperature, certain concentrations and other physical parameters of a melt at elevated temperature.
- This device has a so-called sub-lance, at the tip of which an exchangeable measuring head is arranged, which is moved into the melt by appropriate movement of the lance.
- a transmitter in the measuring head converts sensor signals into a high-frequency signal, which is routed via cable and a plug connection between the measuring head and the metallic sublance.
- the sublance is used to transmit the high-frequency signal and as an antenna to wirelessly transmit the signals to a receiver outside the melt vessel.
- the object of the invention is to propose on the one hand a method and on the other hand a device for its implementation, which allow the determination of parameters with significantly reduced expenditure on equipment, control technology and organization, while at the same time being more reliable than in the prior art. This is intended to make it easier to carry out the measurement in general, but in particular to automate it.
- this object is achieved according to the invention in that the measurement data are transmitted wirelessly directly from the measurement device to the processing device.
- This measure also eliminates the above-described disadvantages of the known methods, which are inseparably connected to the cable, with the connecting cable:
- the service life of the measuring device is no longer limited by the survival time of the cable in the molten metal. In this way, more complex, for example multistage, measuring methods can be carried out by one measuring device.
- Immersion bodies in a discharge station no longer have to be provided with a separate connection for each immersion body
- the processing device comprises a receiving device, e.g. a receiving antenna placed several 100 m in front of the rest of the processing device, e.g. in the form of a computer with the usual peripheral devices, such as a screen, keyboard, printer etc., can be removed. While the receiving device should generally not be too far away from the molten metal for reasons of transmission security, it is advisable to arrange the remaining processing device in a well-protected manner at a sufficient distance from the molten metal. The transmission from the receiving device to the computer will generally take place via a cable.
- the measuring device comprises an integrated transmitting device with which the radiation of signals of the measured values to be transmitted is possible.
- Another important advantage of the method according to the invention can be seen in the fact that the use of a lance can be dispensed with entirely, so that the method can be used cost-effectively in connection with almost all metallurgical vessels.
- the invention is characterized by the omission of all plug connections in the area of the measuring device, since the latter have very often proven to be the weak point of existing devices due to the extreme conditions in operation in the past.
- the embodiment of the method according to the invention is preferred in such a way that the measuring device is introduced into the molten metal from a discharge station using gravity. The measurement can then be carried out without interrupting the converter process.
- the method according to the invention is carried out - in the form of a measuring cycle comprising initialization, selection and preparation of a measuring device, introduction of the measuring device into the molten metal, me and transmission of the data and completion of the measurement - preferably automated.
- a measuring cycle can be triggered by a regular pulse or depending on measured or calculated parameters of the process.
- ISM Industrial Scientific Medical
- IEEE 802.11 in particular at 2.4 GHz or at 433 MHz.
- other frequency ranges can also be used as long as they are sufficiently suitable to transmit measurement data from the measuring device to the processing device during the measurement.
- the object of the invention is further achieved in that with such a device the measurement data can be transmitted wirelessly directly from the measuring device to the processing device.
- This device also has the advantages described above, which result from the elimination of the transmission cable and any plug connections to a lance. Due to the elimination of the cable connection and cable cutting devices, the device according to the invention can be built much more simply and therefore more cost-effectively than the known devices. With the reduced number of assemblies, the space requirement of the device according to the invention is reduced, as is the maintenance and monitoring effort during operation. Overall, the device according to the invention significantly facilitates the automated measurement of parameters of a molten metal.
- the device according to the invention can be used to measure physical or chemical parameters in or on the molten metal.
- thermocouples for measuring the temperature EMF measuring probes for oxygen measurement, sensors for determining the fill level and slag thickness as well as combinations of the sensor elements mentioned are used.
- the determined data can either be transferred directly in analog form or after A / D conversion.
- the measuring device of the device according to the invention can have an integrated transmission element which protrudes from the molten metal during the measurement.
- the receiving antenna can be designed so that it is automatically covered or retracted during the measurement breaks.
- the interference-free transmission is further promoted if the transmitting element, which is designed as an antenna, for example, is largely protected from metal splashes by a cardboard sleeve or by a ceramic coating.
- the projecting transmission element can also be designed as a holder for an immersion body in a discharge device.
- the measuring device can also have an energy storage element, in particular batteries or high-performance capacitors, which are connected or charged to the sensor electronics immediately before the start of the measurement.
- the device according to the invention can be designed in a particularly simple manner in such a way that the measuring device can be introduced manually into the molten metal.
- the embodiment of the device according to the invention is preferred in such a way that the measuring device can be introduced into the molten metal from a discharge station using gravity. This enables the measurement to be carried out without interrupting the converter process.
- the dimensions, in particular length and weight, of such an immersion body result structurally from the intended immersion depth in the molten metal and from the necessary protection of the antenna. Basically, slim designs, that is to say immersion bodies with the smallest possible diameter, have proven to be advantageous.
- the ejection station of a device according to the invention is preferably designed as a magazine that can accommodate several measuring devices.
- the magazining of measuring devices in particular enables the automatic triggering of measuring cycles - as described above - without manual intervention on the device.
- the device according to the invention transmits the measurement data determined by it preferably in the frequency range of the ISM bands (as already explained above).
- the method and the device according to the invention can in principle not only be used in metallic melts, but also in other melt baths - for example in a glass melt.
- the invention also includes the measuring device for introduction into a molten bath at elevated temperature.

- the measuring device 8 is provided at the lower end 9 in a manner not shown with a weight made of a material of a suitable density - for example steel or lead.
- the lower end 9 of the measuring device 8 has a higher density than the molten metal 4, in particular in the case of a molten steel, a density greater than 7.2 g / cm 2 .
- the rod-shaped elongated buoyancy body 17 is produced from a material of lower density, for example from a silicate-bonded cardboard tube.
- the dimensions of the buoyancy body 17 are selected such that, on the one hand, the electrical and electronic components 11, 12, 13, 14 and 16 can be accommodated inside and, on the other hand, the wall thickness selected ensures a protective, heat-insulating shell which is sufficient for these components is.
- the wall thickness of the buoyant body 17 is typically greater than 7 mm.
- the upper end 15 of the measuring device 8 is provided with a coating 18 made of refractory ceramic or cardboard, so that the transmitting antenna 14 protruding from the buoyancy body 17 is protected against damage by metal splashes or slag particles when the measuring device 8 is immersed in the molten metal 4 and during the measurement is.
- the ejection station 6 is arranged laterally above the extraction device 5 and is thus largely protected from the heat radiation emitted by the converter 2.
- the ejection station 6 essentially has a tall, upwardly open box shape with an elongated base area. Its bottom 19 is inclined to a tube 20 attached laterally below the discharge station 6.
- the front wall 21 has an electrically opening flap 22 in front of the tube 20 and an ejection device 24, which is likewise electrically operated, on the opposite rear wall 23.
- a charging station 25 is arranged in the floor 19 of the ejection station 6 directly in front of the flap 22, the transmission coil (not shown) of which charges the capacitor 16 via a receiving coil (not shown) in the measuring device 8. About ten measuring devices 8 are loosely stacked one above the other in the discharge station 6.
- a receiving antenna 26 is also arranged above the extraction device 5, by means of which data transmitted from the area of the molten metal 4 can be recorded and transmitted to the computer 7.
- the flap 20 is opened by a pulse generated in the computer 7 at the discharge station 6 and the measuring device 8 located at the bottom is conveyed into the tube 20 by means of the ejection device 24.
