Abstract

The utility model relates to a composite type lining sleeve for an electric induction furnace body. The utility model is provided with a working lining sleeve of which the outer side is provided with a protective lining sleeve which is tight connected with the working lining sleeve, and thus, the structure of the combined type double layer furnace linings can be formed. Accordingly, the utility model has effective function for preventing leak, and prolongs the service life of the working lining sleeve. After the working lining sleeve is damaged, the protective lining sleeve has a protective function, and thus, the phenomenon of the furnace break can be avoided so as to ensure that production can be continuously carried out. In addition, after the working lining sleeve is damaged, the working lining sleeve can be weeded and can be tied in the protective lining sleeve, so that a great amount of subsidiary materials and refractory materials which are used for the existing building furnace can be saved; thus, the cost of equipment maintenance and the production cost can be reduced.

Description

Combined type induction furnace body lining

The utility model belongs to a kind of Metal Melting utensil, particularly a kind of combined type induction furnace body lining.

In the prior art, the common employing of the body of heater lining of electric induction furnace is built in body of heater or the method for ramming process is made, promptly at insulation heat-barrier materials such as the inboard first place mat mica paper of the induction coil of electric furnace, warning steel plate, asbestos cloth and asbestos boards, then, a core is placed at center at coil, with furnace lining material input in layer, behind the ramming process, form through high temperature sintering more again.The subject matter that this traditional body of heater lining exists is, 1, lack service life, be generally 20～30 stoves the service life of lining during melting, generally is no more than 200 stoves during insulation, and in case stove occurs wearing, not only can make to produce and interrupt, also can cause damage equipment, and, whole furnace lining also will be scrapped and must dismounting heavily build, this not only will consume a large amount of fire proof material of furnace lining, and also influence is produced, and hinders the raising of productivity ratio.2, auxiliary material consumption is big, the cost height, each tamped lining all will use insulating refractorieses such as a large amount of mica paper, warning steel plate, asbestos cloth and asbestos board, the bigger stove of tonnage particularly, the auxiliary material of a furnace lining consumption of knotting are not less than 5000 yuan, and the frequent knotting of furnace lining has increased the operating cost of equipment undoubtedly, has improved production cost of products.3, the labour intensity of rammed lining is big, the energy consumption height, not only the effort, time-consuming, difficult quality guarantee, and, when sintered lining, consume a large amount of electric energy, cause the waste of the energy.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, existing induction furnace body lining is improved, solution large-tonnage induction furnace body lining weak point in service life, the problem that auxiliary material consumption is big provide a kind of combined type induction furnace body lining.

The utility model is achieved in that

It has a work lining, in the outside of work lining a protection lining with its close proximity is arranged, and constitutes combined type double-deck furnace lining structure, the service life of raising furnace lining.

The utility model compared with prior art has following advantage:

1, furnace lining adopts the combined type double-decker, has effectively played the effect that resistance is leaked, and has prolonged the service life of lining; when the work lining damaged, the protection lining had played protective effect, has avoided wearing the phenomenon of stove; guaranteed carrying out continuously of production, safe and reliable, economy and durability.

2, work lining and protection lining are the integral body that is formed by knots tied for twice; both are closely contact both; independent separately again; thereby; corroded by molten steel at the work lining; time spent again; it can be rooted out, and knotting again in the protection lining, used a large amount of auxiliary material and the refractory material of brickwork in the past saved; expense and production cost that maintenance of equipment, equipment move have not only been reduced; also shorten the stoving time of furnace lining greatly, reduced energy resource consumption, and alleviated the labour intensity of brickwork; save maintenance time, improved economic benefit.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

As shown in drawings; the utility model has a work lining 1; in the outside of work lining 1 a protection lining 2 with its close proximity is arranged; constitute combined type double-deck furnace lining structure; work lining 1 and protection lining 2 adopt multiple high strength; the refractory material that wearability is good becomes the ramming mass of combination grain with multiple high-strength binder making; adopt the particular manufacturing craft ramming process; and make through high temperature sintering; during concrete the knotting; should protect lining 2 in the first ramming outside, and it is toasted and sintering, then; the work lining 1 of ramming inboard again, the process of ramming can be undertaken by operating process in the past.

Claims

1, a kind of combined type induction furnace body lining, it has a work lining (1), it is characterized in that, a protection lining (2) with its close proximity is arranged in the outside of work lining (1), formation combined type double-deck furnace lining structure.
