The steel shell furnace is an important part of the complete equipment of the intermediate frequency induction melting furnace. The open steel shell furnace is currently one of the unique advantageous products of our company.

In the R&D and design of the open steel shell furnace, the company mainly improves the electrical efficiency, reduces the failure rate and reduces the maintenance cost. Compared with ordinary steel shell furnaces, our company's steel shell furnaces have the following unique advantages:

1. Open steel structure design: the redundant steel columns are eliminated, the furnace body is easier to observe and repair, and it also reserves space for future capacity upgrades;

2. 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, and it is easy to disassemble and does not affect the maintenance of the furnace body;

3. Waterless yoke: The traditional water-cooled yoke is cancelled, and air-cooled yoke is used except for the water-cooled cable connection part, which greatly avoids the problem of water leakage;

4. 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.
