Abstract
The utility model discloses a furnace cover of an intermediate-frequency furnace. The furnace cover comprises a furnace cover body and a furnace cover ring. The furnace cover ring is fixed to a furnace body. The furnace cover body covers the furnace cover ring. An insulating layer is arranged between the furnace cover ring and the furnace body. The overall furnace cover ring is of a circular ring shape. An annular boss is arranged on the furnace cover ring. The diameter of the inner ring of the annular boss is equal to the diameter of the inner ring of the furnace cover ring. An annular reinforcing rib is arranged outside the annular boss. A boss with the diameter matched with the diameter of the inner ring of the furnace cover ring is arranged below the furnace cover body. According to the furnace cover of the intermediate-frequency furnace, the furnace cover ring is arranged, so that the overall weight of the furnace cover body is supported by the furnace cover ring arranged on the upper portion of the furnace body rather than the furnace cover body is directly pressed on a furnace wall of the furnace body; in addition, the insulating layer is arranged between the furnace cover ring and the furnace body, so that the furnace cover ring is prevented from being burned due to the high temperature of the furnace body; the boss is additionally arranged below the furnace cover body, so that the furnace cover body is prevented from deforming.
Description
Technical field
The utility model relates to a kind of bell of intermediate frequency furnace.
Background technology
Intermediate frequency furnace is a kind ofly to change power frequency 50HZ alternating current into intermediate frequency, the above supply unit to 1000HZ of 300HZ, three-phase main-frequency alternating current, after rectification, become direct current, then direct current is become to adjustable electric current of intermediate frequency, supply with by the intermediate frequency alternating current flowing through in electric capacity and induction coil, in induction coil, produce the highdensity magnetic line of force, and cut the metal material holding in induction coil, and in metal material, produce very large eddy current, utilize electromagnetic induction principle heating of metal.The bell of existing intermediate frequency furnace is all a flat iron plate, easily distortion, thus impact is produced.
Utility model content
The utility model technical issues that need to address are that the bell of existing intermediate frequency furnace is easily out of shape.
For solving the problems of the technologies described above, the utility model provides a kind of bell of intermediate frequency furnace, comprise bell and roof ring, described roof ring is fixed on body of heater, described bell covers on described roof ring, between described roof ring and body of heater, be provided with insulating barrier, described roof ring integral body is annular, on described roof ring, be provided with annular boss, and the inner ring diameter of described annular boss equals the inner ring diameter of described roof ring, arranged outside at described annular boss has a circle reinforcement, described bell below is provided with the boss suitable with described roof ring inner ring diameter.The bell of a kind of intermediate frequency furnace of the present utility model, be provided with roof ring, thereby the total weight that makes bell is bearing on the roof ring of upper of furnace body, rather than be directly pressed on the furnace wall of body of heater, and be provided with insulating barrier between roof ring and body of heater, the high temperature that can prevent body of heater burns out roof ring, and bell below adds boss, can effectively prevent distortion.
Wherein, described thickness of insulating layer is 0.5-2cm, and the outside dimension of described insulating barrier is greater than the outside dimension of described roof ring, at outer ring and the body of heater connecting place of described insulating barrier, is provided with a circle slope.The outside dimension of insulating barrier is greater than the outside dimension of described roof ring can be better heat insulation, and be provided with a circle slope at outer ring and the body of heater connecting place of insulating barrier, is convenient to clear up the residue of fire door.
As further improvement of the utility model, at the inner ring of described roof ring, be also provided with flame retardant coating, on the boss of described bell, be also provided with one deck flame retardant coating.Arranging of flame retardant coating can improve serviceability, increases the service life.
The bell of a kind of intermediate frequency furnace of the present utility model, roof ring is welded into steel plate, is used for supporting bell, and roof ring and bell all adopt refractory material, in order to prevent distortion, can also adopt water cooled cover circle and water cooled cover.The bell of a kind of intermediate frequency furnace of the present utility model, simple in structure, be not easy distortion, and also convenient and practical, can adapt to the daily operating specification of intermediate frequency furnace, be applicable to promoting.
Accompanying drawing explanation

Fig. 2 is top view of the present utility model;
Wherein, 1-bell, 2-roof ring, 3-body of heater, 4-insulating barrier, 5-annular boss, 6-reinforcement, 7-boss.
The specific embodiment
Below in conjunction with accompanying drawing, describe optimal technical scheme of the present utility model in detail.
As shown in the figure, the bell of a kind of intermediate frequency furnace of the present utility model, comprise bell 1 and roof ring 2, described roof ring 2 is fixed on body of heater 3, described bell 1 covers on described roof ring 2, between described roof ring 2 and body of heater 3, be provided with insulating barrier 4, described roof ring 2 integral body are annular, on described roof ring 2, be provided with annular boss 5, and the inner ring diameter of described annular boss 5 equals the inner ring diameter of described roof ring 2, arranged outside at described annular boss 5 has a circle reinforcement 6, described bell 1 below is provided with the boss 7 suitable with described roof ring 2 inner ring diameters, wherein, described insulating barrier 4 thickness are 0.5-2cm, and the outside dimension of described insulating barrier 4 is greater than the outside dimension of described roof ring 2, outer ring and body of heater 3 connecting places at described insulating barrier 4 are provided with a circle slope, inner ring at described roof ring 2 is also provided with flame retardant coating, on the boss 7 of described bell 1, be also provided with one deck flame retardant coating.
The bell of a kind of intermediate frequency furnace of the present utility model, be provided with roof ring, thereby the total weight that makes bell is bearing on the roof ring of upper of furnace body, rather than be directly pressed on the furnace wall of body of heater, and be provided with insulating barrier between roof ring and body of heater, the high temperature that can prevent body of heater burns out roof ring, and bell below adds boss, can effectively prevent distortion; The outside dimension of insulating barrier is greater than the outside dimension of described roof ring can be better heat insulation, and be provided with a circle slope at outer ring and the body of heater connecting place of insulating barrier, is convenient to clear up the residue of fire door; Arranging of flame retardant coating can improve serviceability, increases the service life.
The bell of a kind of intermediate frequency furnace of the present utility model, the material of insulating barrier is alundum (Al2O3), because must have good sealing between roof ring and body of heater, otherwise high-temperature furnace gas can be overflowed, slag making difficulty when not only increasing the heat loss of stove and making to smelt, and easily burn out on body of heater and roof ring.
The bell of a kind of intermediate frequency furnace of the present utility model, roof ring is welded into steel plate, is used for supporting bell, and roof ring and bell all adopt refractory material, in order to prevent distortion, can also adopt water cooled cover circle and water cooled cover.The bell of a kind of intermediate frequency furnace of the present utility model, simple in structure, be not easy distortion, and also convenient and practical, can adapt to the daily operating specification of intermediate frequency furnace, be applicable to promoting.
