Box-type tempering resistance furnace
Box-type tempering resistance furnace is a national standard cycle-operating box-type tempering electric furnace. The furnace top is equipped with a hot air circulation fan. It is mainly used for tempering heat treatment of alloy steel products, various metal parts, and solid-melting of aluminum alloy and copper. , Annealing, aging and other light alloy heat treatment.
Box-type tempering resistance furnace is mainly used for heating, aging, and tempering of petrochemical, medical, laboratory, mold, and steel parts.
The characteristics of the box-type tempering resistance furnace: the aluminum silicate fiber cotton is used to press the insulation layer and the bottom of the furnace. The entire equipment has no refractory bricks, which has the advantages of fast heating and good thermal insulation.
Brief introduction of the structure of the box tempering resistance furnace:
Box-type tempering resistance furnace consists of furnace body and electric control.
The furnace body mainly consists of furnace shell, furnace lining, furnace door and heater.
The furnace shell is welded by steel plate and section steel; the furnace lining is made of energy-saving ultra-lightweight refractory bricks, aluminum silicate fiber and high-quality thermal insulation materials; the heater is wound with high-alloy resistance wires in a spiral shape, and is fixed on both sides of the furnace with high aluminum On the bricks, the furnace bottom heating element is placed on the bottom of the mountain-shaped bricks. The furnace door is lifted or lowered by an electric deceleration mechanism or manually. To prevent leakage of furnace gas.
The electric control part mainly includes two parts: temperature control and operation. The temperature control adopts Japanese imported temperature control meter and thyristor to implement PID control. It is also equipped with a paperless recorder to record the complete process curve, and can record temperature, over temperature alarm and other functions. The operation uses buttons and light display to achieve heating The control of the on-off of the appliance and the lifting and lowering of the furnace door; and the interlock protection device of the heater and the furnace door is provided, which is safe and reliable.
