Box vacuum heat treatment furnace

Model：KJ-TG1000-H350LK2

Description：

This Box vacuum heat treatment furnace mainly used for bright annealing after quenching of high-speed steel, die steel, tool steel, alloy steel, titanium alloy, etc.

Mainly introducing:
The box-type vacuum heat treatment furnace is mainly composed of a heating furnace, a vacuum system, a control system, and a water cooling system. The furnace body is made of high-quality carbon steel and has a built-in stainless steel liner. The furnace is made of alumina polycrystalline fiber, which has good thermal insulation performance, high reflectivity and balanced temperature field. The heating element is high-quality resistance wire. The vacuum system adopts mechanical pumps, diffusion pump sets, high vacuum butterfly valves, vacuum gauges, vacuum release valves, vacuum pipelines, etc., and has an inflation interface. In order to reduce the vibration of the furnace body, metal bellows are used to connect the vacuum pipeline and the pump, and the vacuum measurement is measured by a composite vacuum gauge. The control system is composed of touch screen, programmable controller, temperature control meter, etc., to realize the functions of power supply, control, recording, monitoring, alarm and protection. At the same time, it fully controls the operation of the equipment, provides sequence control signals according to process requirements, and collects on-site feedback signals at the same time to provide conversion, interlocking, indication and alarm signals. The temperature control adopts an intelligent temperature controller, the temperature control accuracy is ±1°C, and 16 process curves can be stored, each process can have 30 segments, and it has the function of PID parameter self-tuning. A K-type thermocouple was used for temperature signal acquisition. The furnace temperature can be displayed digitally on the control cabinet, which is convenient for operators to observe and record.

Product Usage:
This equipment is suitable for high-temperature thermoforming of new materials such as powder metallurgy, functional ceramics, silicon carbide, and alumina. It is mainly used for bright annealing after quenching of high-speed steel, die steel, tool steel, alloy steel, titanium alloy, etc. Welding parts, cold stamping parts, and residual internal stress after quenching of workpieces to prevent deformation and cracking of workpieces.
