LargeThe comprehensive heat treatment technology of quenching and high tempering is broadly applied to the heat treatment processing of axle-type metal pieces, steel work, alloy steel type parts. It is made of high quality thermal insulation material fire resistance material, has good temperature preservation property, and has atmosphere protection; non-oxidation; vertical-type heat treatment; can ensure processed parts not to become deformed, and save raw materials. Equipped with an excellent automatic control and management system, so as to ensure efficiency and safety.
Purpose:
It is applied to the multiplex heat treatment for all kinds of machinery parts, moulds, and iron-based power metallurgy, and also makes heat treatment like non-oxidation (clean) tempering, recrystallized annealing and the diffusion coating treatment of non-ferrous metal and so on.
Proved air malcomising treatment for all kinds of steel machinery parts, automobile crank shafts, piston rings, motorbike brake sheet, and moulds.
Can improve corrosion resistance.
Equipment interoduction:
Electric furnace has heated-air circulation device, which can make atmosphere and temperature uniform inside furnace.
Furnace cover goes up and down by electro-hydraulic gear; goes up and down stably; no vibration.
Electric furnace has quick cooling device, which can make quick cooling according to demand.
Furnace tank, charging basket, and fans adopt heat-resisting alloy steel; long life service.
Electric furnace has interlock protection device, which can avoid failures and accidents due to wrong operation.
Characteristics:
Ageing process after welding is added to vacuum furnace body manufacture; remove post-welding stress; ensure the non-deformation of each seal surface.
Action control adopts solidified circuit; the circuit is simple; reliability is increased greatly.
Has atmosphere protection; non-deformation; non-oxidation; save raw materials.
No population; good environmental protection effectiveness
Has no limit on part shape; can treat complex-shaped small parts in large quantity
Electronic-type temperature control recorder; observe and read history records; make best monitoring at any time.
Temperature control adopts optimized PID control system, rapidly reach steady state; high precision.
Treatment temperature is at about 500~550°C, after this treatment is made on hardened and tempered steel, high-speed steel, and mould steel used for high-temperature processing, steel can still keep its internal hardness.
