Equipment Positioning
The bell-type furnace is a batch-type heat treatment complete equipment featuring movable heating bell and fixed furnace hearth with double-layer sealing structure. Workpieces undergo heat treatment in a sealed protective atmosphere or vacuum environment. It is mainly applied to batch annealing, tempering, stress relief and bright sintering of metal coils, wire rods and large forgings, achieving oxidation-free and decarburization-free bright heat treatment. It is suitable for mass production in metallurgy, non-ferrous metal, machinery and powder metallurgy industries.
Applicable Workpiece Categories
1. Ferrous metals: Cold rolled steel coils, stainless steel coils, electrical steel, wire rods, bearing steel, wind power flanges and large ring forgings
2. Non-ferrous metals: Copper strips & coils, aluminum coils, brass wires and titanium alloy coils
3. Powder metallurgy: Magnetic materials, cemented carbides and green compacts for sintering
4. Large forgings: Wheel hubs, slewing bearings, valves, heavy shaft parts and cylinder forgings
