Abstract
The utility model discloses an intermediate frequency furnace for a stainless steel manufacture device. The intermediate frequency furnace for the stainless steel manufacture device comprises a furnace opening plate, a base plate, a furnace base plate located between the furnace opening plate and the base plate and a heating device. The heating device is located above the furnace base plate. The bottom face of the furnace base plate protrudes downwards and is in a spherical shape. Due to adoption of the design that the bottom face protrudes downwards and is in the spherical shape, influence on the furnace base plate by intermediate frequency furnace flux leakage can be reduced, the furnace base plate is not prone to be melted and service life of the furnace base plate is prolonged.
Description
Technical field
The utility model relates to a kind of apparatus for melting metal, is specifically related to a kind of stainless intermediate frequency furnace that is applicable to make.
Background technology
Intermediate frequency furnace is a kind of supply unit that power frequency 50HZ alternating current is changed into intermediate frequency (300HZ is above to 1000HZ), the three-phase main-frequency alternating current, become direct current after rectification, again direct current is become adjustable electric current of intermediate frequency, supply is by the intermediate frequency alternating current that flows through in electric capacity and induction coil, produce the highdensity magnetic line of force in induction coil, and the metal material that holds in the cutting induction coil, produce very large eddy current in metal material, thereby the metal material of putting into the body of heater inner chamber is added hot smelting.
Existing intermediate frequency furnace has generally comprised a drop-bottom, usually the profile of drop-bottom is cylindrical, the bottom surface is the plane, and the close together of drop-bottom and coil, when smelting metal, the coil electricity on intermediate frequency furnace produces magnetic field, magnetic field produces the leakage field phenomenon at drop-bottom, drop-bottom is melted, drop-bottom is caused damage, reduce the service life of drop-bottom.Especially for the refining of stainless steel material, the stainless steel material heat resistance is strong, and high temperature resistance so intermediate frequency furnace needs higher-wattage to coil electricity, produces stronger magnetic field and makes the stainless steel material fusing, and is also higher to the requirement of drop-bottom.
The utility model content
The purpose of this utility model is to provide a kind of intermediate frequency furnace for the stainless steel manufacturing equipment, can reduce the intermediate frequency furnace leakage field to the impact of drop-bottom, is difficult for making the drop-bottom fusing, has improved the working life of drop-bottom.
For achieving the above object, the utility model adopts following technical scheme:
A kind of intermediate frequency furnace for the stainless steel manufacturing equipment, comprise fire door plate, base plate, drop-bottom and heater between described fire door plate and described base plate, described heater is positioned at above drop-bottom, and the bottom surface of described drop-bottom is heaved downwards and is dome shape.
Further, described drop-bottom inside is provided with the cooling pipe that can pass into cooling water.
Further, it also comprises upper furnace ring, lower stove circle and gripper shoe, and described drop-bottom is arranged in described lower stove circle, and described gripper shoe is accepted described upper furnace ring and described lower stove circle.
Further, be provided with limited post bottom described lower stove circle.
Further, described heater is more than one magnetic conductor and induction coil, and described magnetic conductor and described induction coil are positioned at described drop-bottom top, and described magnetic conductor distributes along described induction coil even circumferential.
Further, between described fire door plate and described base plate, hydraulic column is housed, described hydraulic column bottom is connected with described base plate, and described hydraulic column top is connected with described fire door plate.
Further, be provided with column between described fire door plate and described base plate, described column bottom is connected with described base plate, and described column top is connected with described fire door plate.
The beneficial effects of the utility model are:
The utility model provides a kind of intermediate frequency furnace for the stainless steel manufacturing equipment, and the drop-bottom design of adopting the bottom surface to heave downwards to be dome shape can reduce the intermediate frequency furnace leakage field to the impact of drop-bottom, is difficult for making the drop-bottom fusing, the service life of having improved drop-bottom.

The specific embodiment
A kind of intermediate frequency furnace for the stainless steel manufacturing equipment as shown in Figure 1, comprise fire door plate 1, base plate 2, the drop-bottom 3 between fire door plate 1 and base plate 2 and heater 4, heater 4 is positioned at drop-bottom 3 tops, the bottom surface of drop-bottom 3 is heaved downwards and is dome shape, and drop-bottom inside is provided with the cooling pipe 31 that can pass into cooling water.Heater 4 is more than one magnetic conductor 41 and induction coil 42, magnetic conductor 41 and induction coil 42 are positioned at drop-bottom 3 tops, magnetic conductor 41 distributes along induction coil 42 even circumferentials, and intermediate frequency furnace produces magnetic force by magnetic conductor 41 cutting induction coils 42, and metal material is heated.
Intermediate frequency furnace also comprises upper furnace ring 5, gripper shoe 6 and lower stove circle 7, and drop-bottom 3 is arranged in lower stove circle 7, and gripper shoe 6 is accepted upper furnace ring 5 and lower stove circle 7, and lower stove circle 5 bottoms are provided with limited post 10.
Between fire door plate 1 and base plate 2, hydraulic column 8 is housed, hydraulic column 8 bottoms are connected with base plate 2, and hydraulic column 8 tops are connected with fire door plate 1, and this hydraulic column 8 can be used for intermediate frequency furnace is overturn, thereby the molten metal after melting is poured out.Also be provided with column 9 between fire door plate 1 and base plate 2, column 9 bottoms are connected with base plate 2, and column 9 tops are connected with fire door plate 1.
In sum, the utility model is designed to heave downwards by the bottom surface with drop-bottom 3, makes the bottom surface of drop-bottom 3 large apart from the distance meeting change of the induction coil 42 on intermediate frequency furnace, admittedly can reduce leakage field to the impact of drop-bottom 3, be difficult for making drop-bottom 3 fusings, increase the service life of drop-bottom 3.
The above, it is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, therefore every technical solutions of the utility model content that do not break away from,, all still belong in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
