Abstract
The invention relates to a method for pouring a cast part, which comprises the steps of firstly carrying out drainage before pouring molten steel, and leading drainage sand to flow down but not enter into the molten steel; then closing a lower sliding plate, blowing argon through a ventilation plug arranged on the lower sliding plate, and leading the molten steel on a water port to be in the flowing state, and realizing the purification of the molten steel; and not blowing the argon when opening the lower sliding plate for pouring. The position of the ventilation plug on the lower sliding plate is as follows: a water supply inlet corresponds to the position of the lower sliding plate when the lower sliding plate is in the closing state, and the position is just the central position of the ventilation plug. The ventilation plug is connected with a gas guide tube, and the argon is introduced through the gas guide tube. Compared with the prior art, the method has the benefits that the method can effectively solve a ventilation sliding plate for the problem of solidification of the molten steel at the water port when the sliding plate is closed, and the method can realize the control of the pouring speed at the later stage of pouring by mounting the ventilation plug on the sliding plate and introducing the argon through the ventilation plug when the sliding plate is closed, thereby greatly improving the quality of a product.
Description
Technical field
The present invention relates to a kind of method of metallurgy industry pouring cast part.
Background technology
In the prior art, all adopt the handgrip jar early stage when pouring into a mould steel-casting, though can control poring rate, but serious restriction is received in the fluctuation of liquid steel temperature and molten steel amount, particularly multiple tank closes the large-scale steel-casting that waters and can not produce, the promoting the use of on fining pot along with slide mechanism and ventilative commentaries on classics, the cast of large steel ingot and big foundry goods obtains fine solution, but the even control of liquid steel temperature and later stage point are annotated, requiring slide plate repeatedly to open waters and can't control, in case arrhea then the mouth of a river goes out molten steel just solidifies, require to open once more to water and cut eye after often needing to close, slide plate often occurs and open or not, do not close the slide plate bleed-out accident that causes, all constitute a serious threat for production and quality, be difficult to guarantee cast smoothly for one jar of a plurality of living-article of cast or polydisc steel ingot, casting quality is difficult to guarantee.Therefore, how to improve sled mechanism, improve slide plate switch number of times and improve, improving casting quality is a great problem.
Summary of the invention
The method of the pouring cast part of the problem of place, mouth of a river molten steel solidification when the purpose of this invention is to provide a kind of effective solution slide plate and closing, by porous plug is installed on slide plate, the logical argon gas of porous plug when slide plate is closed has been realized cast later stage control poring rate, has improved product quality greatly.
The present invention is achieved through the following technical solutions:
A kind of method of pouring cast part is characterized in that, this method may further comprise the steps:
1) before pouring molten steel, carries out drainage earlier, make under the drainage sand flow not enter in the molten steel;
2) close lower skateboard then,, make that molten steel is in flow regime above the mouth of a river, and realize purification molten steel by the porous plug blowing argon gas that is provided with on the lower skateboard;
When 3) the unlatching lower skateboard was poured into a mould, porous plug is blowing argon gas not.
Porous plug position on the described lower skateboard is: when lower skateboard was in closed condition, the position of the corresponding lower skateboard of filling pipe end promptly was the center of porous plug.
Described porous plug is connected with wireway, feeds argon gas by wireway.
Compared with prior art, the invention has the beneficial effects as follows:
Efficiently solve the ventilative slide plate of slide plate problem of place, mouth of a river molten steel solidification when closing, by porous plug is installed on slide plate, the logical argon gas of porous plug when slide plate is closed has been realized cast later stage control poring rate, has improved product quality greatly.
Description of drawings
Fig. 1 is the structural representation that the present invention adopts device.
Among the figure: the mouth of a river under the 1-pocket block 2-filling pipe end 3-upper slide 4-lower skateboard 5-porous plug 6-
The 7-wireway
The specific embodiment
See Fig. 1, a kind of ventilative slide plate comprises upper slide 3, lower skateboard 4, on lower skateboard 4, be provided with the porous plug 5 that is used for being blown into argon gas, when lower skateboard 4 is in closed condition, feed argon gas to porous plug 5 by wireway 7, make molten steel be in flow regime, promptly reached the noncondensing purpose of molten steel.
Porous plug position on the lower skateboard is: when lower skateboard was in closed condition, the position of the corresponding lower skateboard of filling pipe end promptly was the center of porous plug.
Adopt the method for above-mentioned ventilative slide plate pouring cast part, this method may further comprise the steps:
1) before pouring molten steel, carries out drainage earlier, make under the drainage sand flow not enter in the molten steel;
2) close lower skateboard then, by the porous plug blowing argon gas that is provided with on the lower skateboard, make that molten steel is in flow regime above the mouth of a river, and realize purification molten steel, even composition and temperature, cleaning molten steel make in the slag blanket of field trash attached to the molten steel top of argon gas bubbles come-up of molten steel molten steel inside.
When 3) the unlatching lower skateboard was poured into a mould, porous plug is blowing argon gas not.
Claims (3)
1. the method for a pouring cast part is characterized in that, this method may further comprise the steps:
1) before pouring molten steel, carries out drainage earlier, make under the drainage sand flow not enter in the molten steel;
2) close lower skateboard then,, make that molten steel is in flow regime above the mouth of a river, and realize purification molten steel by the porous plug blowing argon gas that is provided with on the lower skateboard;
When 3) the unlatching lower skateboard was poured into a mould, porous plug is blowing argon gas not.
2. the method for a kind of pouring cast part according to claim 1 is characterized in that, the porous plug position on the described lower skateboard is: when lower skateboard was in closed condition, the position of the corresponding lower skateboard of filling pipe end promptly was the center of porous plug.
3. the method for a kind of pouring cast part according to claim 1 and 2 is characterized in that, described porous plug is connected with wireway, feeds argon gas by wireway.
