The intermediate-frequency conduction furnace comprises a furnace body, a conductive inductor, an insulating cylinder, an upper water jacket, a lower water jacket and a graphite crucible heating element, wherein the conductive inductor is installed on the outer surface of the furnace body by the insulating cylinder; the graphite crucible heating element is arranged inside the furnace body; a carbon black insulating layer is arranged between the furnace body and the graphite crucible heating element; and the upper part and the lower part of the furnace body are respectively provided with the upper water jacket and the lower water jacket. The intermediate-frequency conduction furnace is a rectangular body, solves the problems that as for the existing drum-shaped conduction furnace, the length of magnetic lines of force is different in production of certain rectangular products, and the products are not heated uniformly, therefore, the power consumption is high and energy materials are wasted; in addition, the intermediate-frequency conduction furnace has simple structure, can directly conduct thermal motion of molecules to a container and generate high temperature for producing and smelting raw materials, effectively saves the production cost and improves the quality of products.
Description
Technical field:
The utility model relates to a kind of quartz glass heat remodeling intermediate frequency furnace, belongs to the induction heating equipment technical field.
Background technology:
Induction furnace is that a kind of induction coil that utilizes produces the electric furnace that induced-current adds thermal material, induction furnace is divided into channel induction furnace and coreless induction furnace two big classes usually, the cored inductor that passes of channel induction furnace with the power frequency supply power supply, is mainly used in the melting of various metals such as cast iron, brass, bronze.Coreless induction furnace does not have iron core to pass inductor, and coreless induction furnace can be divided into power frequency induction furnace, frequency tripling induction furnace etc. again, is mainly used in the extraordinary high-temperature material of melting.The major advantage of induction furnace is that material loss is little, if heating of metal material, then material is put into the crucible that refractory material is made, if heating nonmetal material, then material is put into the crucible that graphite material is made, when increasing exchanges the electricity frequency, the then corresponding raising of induced-current frequency, the heat of generation increases.In addition, the induction furnace heating is rapid, temperature is high, convenient operation and control, and material is contaminated few in heating process, and product quality can be guaranteed.
The induction furnace that uses in the prior art is round barrel shape, and the induction furnace advantage of round barrel shape is that magnetic line of force distribution is more even in the course of work, the length unanimity; Its shortcoming is when producing some specific rectangular products, the advantage of round barrel shape induction furnace then can't be brought into play, magnetic line of force length in the course of work is different, it is inhomogeneous that product is heated, product quality can not get guaranteeing, simultaneously also cause waste of electric energy, and then cause production cost to increase, influence the benefit of enterprise.
Summary of the invention:
The purpose of this utility model is: at the deficiencies in the prior art, provide a kind of and can adapt to rectangular products production, reduce waste of energy, guarantee product quality, the quartz glass that reduces production costs heat remodeling intermediate frequency furnace.
The utility model is to realize above-mentioned purpose by following technical solution:
A kind of quartz glass heat remodeling intermediate frequency furnace, it is by body of heater, the conduction inductor, insulated column, upper water sleeve, lower water jacket, the graphite crucible heater constitutes, it is characterized in that: the outer surface of body of heater is equipped with the conduction inductor by insulated column, and the graphite crucible heater is equipped with in the inside of body of heater, is provided with the carbon black heat-insulation layer between body of heater and the graphite crucible heater; The upper and lower of body of heater is equipped with upper water sleeve and lower water jacket respectively.
Described body of heater and graphite crucible heater are corresponding cuboid, and its four interior angles are respectively 90 °, but also circular arc is excessive.
Described upper water sleeve and lower water jacket are a hollow rectangle body corresponding with body of heater, and a side of upper water sleeve and lower water jacket is equipped with cooling water turnover pipe respectively.
Described body of heater is built into by the fire-resistant corundum brick of rectangle.
The utility model beneficial effect compared with prior art is: body of heater of the present utility model is a cuboid, having avoided existing body of heater is that induction furnace magnetic line of force length when the melting rectangular products of round barrel shape is different, the product inhomogeneous power consumption that causes that is heated is big, the problem of waste of material.And the utility model is simple in structure, can directly form molecular thermalmotion to container and produce high temperature, and raw material are smelted, and has saved production cost effectively, has improved product quality.
