Abstract
The utility model discloses a structure of a medium-frequency induction electric furnace. The structure comprises a furnace shell, a furnace lining and an inductor coil, wherein the inductor coil is wound on the furnace lining, and a coil coating layer is coated between the furnace lining and the inductor coil. The coil coating layer is coated between the furnace lining and the inductor coil, and the coil coating is made from corundum fire-proof material, is proportioned by different grains and quick-setting cement, is good in insulativity, and is very high in fire-proof degree and high-temperature compression strength, so that the leakage of the iron liquid can be effectively avoided, the inductor coil can be protected, and the service life of the medium-frequency induction electric furnace can be prolonged. The medium-frequency induction electric furnace with the structure can be constructed without paving the sheet mica, the asbestos cloth and the glass wool cloth, so that the furnace construction time can be saved, the furnace construction period can be shortened, and the production efficiency can be improved.
Description
Technical field
The utility model relates to a kind of cast iron melting device, particularly a kind of medium-frequency induction furnace.
Background technology
The medium-frequency induction furnace melting has that firing rate is fast, oxidation is few, Composition Control is convenient, reduces the melting cost, working condition is good, can produce advantages such as various different products, uses increasingly extensive in high quality casting is produced.Inductor is the important component part of medium-frequency induction furnace, and the medium-frequency induction furnace melting is to be delivered in the metal charge by the power of inductor with power supply, and the heating of metal furnace charge melts then and heats up.The preheating of metal charge, fusing, intensification are to be finished by inductor, so the good inductor of maintaining plays decisive role to the life-span of medium-frequency induction furnace.The inductor of medium-frequency induction furnace by very big electric current, produces very high heat this moment when smelting iron liquid, in order to take away the heat that inductor produces, inductor generally is to use water cooling.Medium-frequency induction furnace causes iron liquid seepage because a variety of causes furnace lining can crack and corrode if any big crackle, damages inductor when serious, at this moment, meets as high temperature iron liquid and cooling water, can set off an explosion the crisis personal safety.
For safe operation, generally all need to be provided with insulation, fire-resistant and resistant to elevated temperatures material between the inductor of medium-frequency induction furnace and the furnace lining.Original medium-frequency induction furnace at first need be coated with insulated paint and dries when brickwork on inductor, and then between inductor and furnace lining, lay mica sheet, asbestos cloth and glass wool cloth, to reach insulation, fire-resistant, resistant to elevated temperatures purpose.But the medium-frequency induction furnace brickwork time of this structure is longer, begins to need two days time to the medium-frequency induction furnace melting from brickwork, and the brickwork cycle is longer, influences the arrangement of ordinary production, and production efficiency can not effectively be brought into play.
The utility model content
At above-mentioned the deficiencies in the prior art, the technical problems to be solved in the utility model provides short medium-frequency induction furnace of a kind of simple in structure, brickwork time.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of medium-frequency induction furnace structure comprises furnace shell, furnace lining and inductor coil, and described inductor coil scribbles one deck coil dope layer between described furnace lining and the described inductor coil on described furnace lining.
Preferably, the bottom of described furnace lining is provided with the silk of reporting to the police, and described warning silk is connected with warning device.
Technique scheme has following beneficial effect: this medium-frequency induction furnace structure scribbles one deck coil dope layer between inductor coil and furnace lining; coil coating is by corundum based refractory materials; form through variable grain and quick hardening cement proportioning; have good insulating properties, very high refractoriness and crushing strength under high temperature; can effectively prevent iron liquid seepage; inductor coil is formed protection, prolong the service life of medium-frequency induction furnace.And the medium-frequency induction furnace of this structure need not to re-lay mica sheet, asbestos cloth and glass wool cloth when brickwork, can save the time of brickwork, shortens the brickwork cycle, enhances productivity.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, this medium-frequency induction furnace structure comprises furnace shell 5, furnace lining 1 and inductor coil 3, and furnace lining 1 is positioned at furnace shell 5, and inductor coil 3 scribbles one deck coil dope layer 2 between furnace lining 1 and the inductor coil 3 on furnace lining 1.The bottom of furnace lining 1 is provided with warning silk 4, and the silk 4 of reporting to the police is connected with the warning device (being to show among the figure) of outside.When furnace lining 1 had crackle molten iron seepage, the silk 4 of reporting to the police can in time feed back to warning device with signal made its warning, in time furnace lining was keeped in repair to remind the maintenance personal.
According to test, adopt the medium-frequency induction furnace of this structure, the brickwork time can shorten to one day by original two days, again brickwork once, melting every day molten iron is by 40 tons as removing old furnace lining in average 28 days, then can increase by 480 tons of the smelting iron water yields whole year, as seen adopt the medium-frequency induction furnace of this kind structure that production efficiency is significantly improved.
More than medium-frequency induction furnace structure that the utility model embodiment is provided be described in detail; for one of ordinary skill in the art; thought according to the utility model embodiment; all can change to some extent in specific embodiments and applications; therefore this description only is used in the utility model embodiment is described; should not be construed as restriction of the present utility model, all any changes of being made according to the utility model design philosophy are all within protection domain of the present utility model.
Claims (2)
1. a medium-frequency induction furnace structure comprises furnace shell, furnace lining and inductor coil, and described inductor coil is characterized in that on described furnace lining: scribble one deck coil dope layer between described furnace lining and the described inductor coil.
