No magnets in the country transformers, furnace manufacturing industry has been very widely used. Transformer industry dedicated to the core rod, clamps, tank walls, flanges and other requirements of non-magnetic components. Mainly used in electric furnace industry, mining and metallurgy furnace, calcium carbide furnace smelting, nickel iron smelting furnace, ferrosilicon smelting furnace, electrolytic manganese smelting and other equipment manufacturers. Effectively improve the device performance, lower manufacturing costs and make products more competitive.

No magnets are now widely used in many electrical products:
1 medium-sized transformer tank inside a magnetic shield, core pull plate, coil clamps, bolts and other structural parts of the leakage magnetic field;
2, medium and large generator stator coil tie ring, retaining ring, tooth pressure parts and other structural parts;
3, large voltage, high-current high-voltage bushing parts conveyor line and adjacent steel frame;
4, special smelting furnace lining, lid, plywood and electronic mixing device electrode structure;
5, magnetic separation equipment cylinder, the election boxes and separator, lifting magnet;
6, nautical compass and electrical instrumentation and other industries
