Description
Technical field
the utility model belongs to technical field of metallurgical equipment, specifically refers to a kind of furnace drying device of novel centreless electric furnace.
Background technology
Centreless electric furnace is widely used in zinc founding, zinc-containing alloy configuration etc. are produced, and after electric furnace is newly built by laying bricks or stones, general nature starts baker and heats up after dry one week, continue can come into operation after 10 to 15 days.Prior art generally adopts the roast technic such as firewood baker or resistance wire baker, though this type of technological operation is comparatively easy, all exists and cannot regulate and control fire box temperature and heating rate, cause each position of furnace lining to be heated inequality, can not the technical problem of expanded by heating simultaneously; And in baker temperature-rise period, crucible furnace lining is uneven at expanded by heating, in the situations such as too fast or unexpected cooling that heat up, all can crack, cause the molten metal seepage put into operation in rear furnace body.Therefore, adopt certain technological measure to realize carrying out Effective Regulation to the temperature in burner hearth or heating rate, effectively can ensure the service life of crucible furnace lining, avoid furnace body leakage.In addition, Unequal distance between resistance wire and hearth wall in resistance wire baker, the near spot temperature of distance resistance wire is high, the shortcoming that the spot temperature of distance is low, is heated uneven; Moreover during resistance wire baker, cannot close bell, there is certain heat loss, cannot ensure Baker effect; And there is certain potential safety hazard in the resistance wire leaked outside.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of centreless electric furnace furnace drying device, can Effective Regulation baker furnace temperature, avoids crucible furnace lining inequality of being heated to crack.
The utility model is by the following technical solutions:
A kind of centreless electric furnace furnace drying device, comprises furnace shell, forms burner hearth in described furnace shell by crucible furnace lining, induction coil is provided with between crucible furnace lining and furnace shell, induction coil connects external circuit control system, and be provided with cylindrical magnetic conducting body in described burner hearth, cylindrical magnetic conducting body and burner hearth circumference are equidistantly arranged; Thermo detector is provided with between described cylindrical magnetic conducting body and hearth wall.
Described cylindrical magnetic conducting body is the cylinder steel plate that multilayer concentric is arranged, and passes through link of boards between steel plate.
Distance between described outermost layer tubular steel plate and hearth wall is 80-160mm.
Described cylindrical magnetic conducting body is provided with hanger.
The beneficial effects of the utility model are:
1, by the magnetic conductor generation electromagnetic induction that electric furnace body induction coil and electric furnace inside are set up, the heat produced by electromagnetic induction reaches the object of baker, and by regulating and controlling the lifting of induction coil voltage, realizes the Effective Regulation to furnace temperature;
2, magnetic conductor and hearth wall are equidistantly arranged, and avoid resistance wire baker and to be heated uneven problem;
3, Effective Regulation can be carried out to furnace temperature, avoid crucible furnace lining to crack because of be heated inequality or temperature shock, ensure that the service life of furnace lining, rational in infrastructure, safe and effective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of cylindrical magnetic conducting body in the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model and effect thereof are described further.
As shown in Figure 1, 2, a kind of centreless electric furnace furnace drying device, comprise furnace shell 1, burner hearth 3 is formed by crucible furnace lining 2 in described furnace shell 1, induction coil 4 is provided with between crucible furnace lining 2 and furnace shell 1, described induction coil 4 connects external circuit control system, can realize the lifting to induction coil 4 voltage by the external circuit control system of electric furnace body; Be provided with cylindrical magnetic conducting body 5 in described burner hearth 3, cylindrical magnetic conducting body 5 and burner hearth 3 circumference are equidistantly arranged; Be provided with thermo detector 6 between described cylindrical magnetic conducting body 5 and hearth wall, temperature is by the display of electric furnace external circuit system; There is electromagnetic induction in the cylindrical magnetic conducting body 5 set up by electric furnace body induction coil 4 and electric furnace inside, the heat produced by electromagnetic induction reaches the object of baker, and by regulating and controlling the lifting of induction coil 4 voltage, realize the Effective Regulation to furnace temperature, resistance wire baker then separately must connect power supply; Reduce induction coil 4 voltage or power-off, all can control fire box temperature flexibly, reach baker furnace temperature and be elevated by given pace; Solve the problem that in firewood, combustion gas, resistance wire baker process, temperature cannot accurately control; Avoid crucible furnace lining 2 to crack because of be heated inequality or temperature shock, leakage occurs, ensure that the service life of furnace lining.The cylinder steel plate 7 that described cylindrical magnetic conducting body 5 is arranged for multilayer concentric, is connected by gusset 8 between steel plate; Burner hearth 3 internal magnetic field intensity is successively decreased by circumferential center, cylinder steel plate 7 is traditionally arranged to be layer 2-3, columnar structured consistent with electric furnace liner structure, spacing is equal to, furnace lining energy thermally equivalent, the distance between general outermost layer cylinder steel plate 7 and hearth wall is between 80-160mm, and the spot temperature that when avoiding resistance wire baker, distance resistance wire is near is high, the spot temperature of distance is low, and furnace lining is heated uneven shortcoming; Described cylindrical magnetic conducting body 5 is provided with hanger 9, facilitates hanging in of cylindrical magnetic conducting body to hang out.
During operation, cylindrical magnetic conducting body 5 is hung in burner hearth 3, be placed on the fragment of brick 10 that props up in advance, and make cylindrical magnetic conducting body 5 be positioned at burner hearth center; Utilize electric furnace body power supply, heat up gradually according to certain control rate, cylindrical magnetic conducting body 5, after electric furnace coil electricity, produces electromagnetic induction, for baker provides the thermal source be evenly distributed, solves heating rate inequality, furnace lining is heated uneven problem; Especially the external circuit control system of induction coil 4 can regulate different voltage, and reads in-furnace temperature by thermo detector 6, realizes the effective control to temperature; Under other parts of electric furnace or system fault conditions, also can power down process at any time, continue afterwards to heat up, flexibly and easily.When furnace temperature reaches set point of temperature, such as zinc founding industry is 600 DEG C, hangs out cylindrical magnetic conducting body 5, and completing baker can put into production.
