Abstract
The utility model relates to an electric furnace, in particular to an electric induction furnace, and belongs to the technical field of metallurgy. The problem that the side face or the bottom of the conventional electric furnace is easy to stretch out in the prior art is solved. The electric induction furnace mainly comprises a furnace shell, wherein a furnace lining is arranged inside the furnace shell; a furnace cover board is arranged on the top of the furnace shell and fixed on the furnace shell through a copper screw; an induction ring, a first asbestos board and an insulation column are arranged between the lateral surfaces of the furnace lining and the furnace shell; a second asbestos board and an insulation base board are arranged between bottom surfaces of the furnace lining and the furnace shell; a fire door brick is arranged above the furnace lining; a cooler is arranged between the furnace lining and the second asbestos board; and an insulation top board is arranged on the copper screw below the fire door brick. The electric induction furnace is mainly applied in industries, such as metallurgy, casting and the like.
Description
Technical field
The utility model relates to a kind of electric furnace, relates in particular to a kind of electric induction furnace, and it belongs to metallurgical technology field.
Background technology
Medium-frequency induction furnace is because its smelting efficiency is high, molten metal composition temperature is with control, simple operation and other advantages, extensive use in metallurgical, casting industry.The body of heater of tradition electric furnace the stove accident occurs wearing through be everlasting side or bottom.Wear the stove accident if appearing at the side can in time come to light and handle, as under copper hydrostatic pressure power and high temperature acting in conjunction, understand one bottom occurring in and to receive, cause very serious consequence.Reason is because the bottom is used to support the refractory brick and the furnace lining of furnace lining; The impact of material piece in receiving the charging process, for a long time static pressure and fusion process repeatedly harmomegathus and cause fragmentation, and cause the bottom furnace lining to can not get evenly enough supports, and then cause furnace lining to sink to making the sinter layer of bottom or side to crack; Stove is worn in formation; And all to change during each brickwork, cause short, production cost of induction furnace life-span in furnace life to increase, become the outstanding problem that restriction is produced.
The utility model content
The utility model is prone to the deficiency that stove is worn in side or bottom to traditional electrical heat size in the prior art, and a kind of electric induction furnace is provided.
The technical scheme that the utility model solves the problems of the technologies described above is following:
A kind of electric induction furnace comprises furnace shell and furnace lining, and said furnace lining is located at furnace shell inside, is provided with induction coil and asbestos board first between the side of said furnace lining and furnace shell, is provided with asbestos board second between the bottom surface; Said furnace lining top is provided with the fire door brick, is provided with cooler between said furnace lining and the asbestos board second.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, said furnace shell top is provided with stove cover plate, and said stove cover plate is fixedly mounted on the furnace shell through copper screw bolt.
Further, be provided with insulated column between said induction coil and the furnace shell.
Further, the copper screw bolt below the said fire door brick is provided with the insulation top board.
Further, be provided with insulating base between said asbestos board second and the furnace shell.
Compared with prior art, the beneficial effect of the utility model is: furnace bottom uses a kind of metal cooler with type to substitute original refractory brick, utilizes the fluid media (medium) of cooler inner loop to take the part heat out of; Alleviated the bottom violent expansion, shrink alternately phenomenon, the bottom and the side furnace lining temperature difference are reduced, the shrinkage ratio of furnace lining was more approaching in the past on every side to make copper water; The sinter layer of furnace lining and suffered stress are more even, and the time that furnace lining is cracked is able to postpone, thereby have avoided wearing the generation of stove accident; Furnace life is than tens original stoves; Surplus having improved 20 times, being up to 450 stoves average furnace life is 300 stoves, has made things convenient for scheduling of production; And realized the governing plan of workshop appliance periodical repair.Surplus every year, only furnace building material, manual work, the electricity charge etc. practiced thrift 10 ten thousand yuan, this metal cooler can be broken, can use for a long time, significantly improved operating efficiency.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Stove cover plate in the drawings, 1; 2, fire door brick; 3, insulation top board; 4, insulated column; 5, induction coil; 6, copper screw bolt; 7, furnace lining; 8, furnace shell; 9, asbestos board first; 10, cooler; 11, asbestos board second; 12, insulating base.
The specific embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
A kind of electric induction furnace comprises furnace shell 8, and said furnace shell 8 inside are provided with furnace lining 7, and the top is provided with stove cover plate 1, and said stove cover plate 1 is fixedly mounted on the furnace shell 8 through copper screw bolt 6; Be provided with induction coil 5, asbestos board first 9 and insulated column 4 between the side of said furnace lining 7 and furnace shell 8, be provided with asbestos board second 11 and insulating base 12 between the bottom surface; Said furnace lining 7 tops are provided with fire door brick 2, are provided with cooler 10 between said furnace lining 7 and the asbestos board second 11, and the copper screw bolt 6 of said fire door brick 2 belows is provided with insulation top board 3.
The utility model is when making, and the material of cooler 10 can be various metal materials such as aluminium, copper, steel, and cooler 10 can obtain through the number of ways of casting, welding, pressure processing, and can adjust making according to the demand of different body of heater models.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
