    The purpose of the billet intermediate frequency induction heating furnace : used to heat carbon steel, alloy steel, ball bearing steel, including ferritic steel and austenitic steel, to the maximum extrusion temperature of 1250T . Billet "plus hot" furnace heated to 1250T after the punch a hole shall be due to a decrease in the temperature of the billet , "then the heating" furnace, and then extruded.

    The intermediate frequency induction heating furnace can process 4 kinds of billets with different diameters. Changing from one diameter billet to another diameter billet requires some adjustments to the furnace and replacement of the inductor.

    The structure of the intermediate frequency induction heating furnace: The induction heating furnace is vertical and uses hydraulic transmission, which is convenient for automatic control.

    The coil of the inductor is wound with a special-shaped pure copper tube, arranged in a single layer, cooled by water, with a magnetic conductor, and an open tube made of high temperature resistant material in the coil, and there is a protection between the coil and the heat resistant tube cylinder.

    "Plus hot" and the furnace "re Technical Data heating" of the furnace are shown in Table 12-8 .
