There are mainly two kinds of steel shell furnaces on the market, closed shell furnaces and column steel shell furnaces. Compared with closed steel shell furnaces, column type steel shell furnaces are stronger and easier to overhaul. The structure of the company's column-type steel shell furnace is not much different from the steel shell furnace on the market, but the details are different, mainly reflected in the following aspects:

1. All-round protective cover: a protective cover is set on the periphery of the furnace body to effectively protect the safety of the induction coil and water-cooled cable, easy to disassemble, and does not affect the maintenance of the furnace body;

2. Waterless yoke: The traditional water-cooled yoke is canceled, and the air-cooled yoke is used except for the water-cooled cable connection part, which greatly avoids the trouble of water leakage in the later stage;

3. Rodless coil: The coil is wound by the horizontal winding process, and the turns of the coil are closely consistent, without segmentation, and the maximum electrical efficiency can be obtained; at the same time, the coils support each other, the overall structure is sturdy, and will not be deformed after long-term use; in addition, The coil is treated with porcelain-fired insulation, and insulating gaskets are evenly implanted between adjacent turns, so the insulation performance is superior, and high-voltage ignition can be effectively avoided.
