Mainly used for alloy steel products, various metal parts tempering heat treatment, and aluminum alloy, copper solid melting, annealing, aging and other light alloy heat treatment.
Main USES of box-type tempering resistance furnace: used for heating, aging and tempering of petrochemical industry, medical treatment, laboratory, mould and steel parts.
Equipment structure features:
The box-type tempering resistance furnace is the national standard periodic operation box-type tempering electric furnace, the furnace top is installed with hot air inside circulation fan, the main box-type tempering resistance furnace features: aluminum silicate fiber cotton is used to press the insulation layer and furnace bottom, the whole equipment has no firebrick, with the advantages of fast temperature rise and heat preservation.
Brief introduction to the structure of box-type tempering resistance furnace:
The box-type tempering resistance furnace is composed of furnace body and electric control.
The furnace body is mainly composed of furnace shell, furnace lining, furnace door and heater.
The furnace shell is welded by steel plate and section steel. The furnace lining is composed of energy saving ultra-light firebrick, aluminum silicate fiber and high quality insulation materials. The heater is spiral wound with high alloy resistance wire and is fixed on the high aluminum shelf brick on both sides of the furnace, and the heating element at the bottom is placed on the mountain shelf brick at the bottom. The lifting of the furnace door is driven by electric deceleration mechanism or manual operation. The furnace door is made of aluminum silicate fiber and equipped with automatic pressing device to improve the sealing of the furnace body and prevent the leakage of furnace gas.
The electronic control part mainly includes temperature control and operation. Temperature control adopts temperature control meter imported from Japan and thyristor to implement PID control. In addition, it is equipped with paperless recorder to record complete process curve, and has functions such as temperature timing and overtemperature alarm. The operation adopts button and light display to realize the control of on and off of heater and lifting of furnace door. And with the heater and furnace door chain protection device, safe and reliable.
