1. Trolley-type resistance furnace is a national standard energy-saving cycle type operating furnace. Ultra-efficient, all-fiber lining structure, saving up to 60%. The exclusive production uses composite high-aluminum porcelain nail set, trolley anti-collision sealing brick, automatic sealing trolley and furnace door, integrated rail, no need to build foundation, can be used on level ground. Mainly used for high chromium, high manganese steel castings, ductile iron, rolls, steel balls, 45 steel, stainless steel and other quenching, annealing, aging and heat treatment of various mechanical parts.

2. The body part of the trolley type electric resistance furnace mainly includes a furnace shell, a furnace lining, a heating element, a furnace door and a trolley. The furnace shell is welded by steel plate and steel. The furnace lining is made of energy-saving ultra-light refractory brick, aluminum silicate fiber and high-quality insulation material. The heating element is spirally placed on the lining and the trolley brick by a high-alloy resistance wire; the trolley can be moved back and forth to facilitate loading and unloading, and a novel automatic sealing is adopted between the furnace and the furnace shell to improve the sealing performance; The lifting of the door and the entry and exit of the trolley are all driven by an electric speed reduction mechanism. The bottom plate of the furnace is a heat-resistant steel casting, and the trolley is inclined to discharge the mechanism.

3. The electronic control part mainly includes two parts: temperature control and operation. The temperature control adopts the intelligent digital display control, adopts the advanced PID algorithm to adjust, and the power adjustment module of the main circuit forms a closed-loop control with precise control and stable operation. The recorder is also equipped with a complete process curve and can be over-temperature alarmed. The operation uses the button to move to realize the entry and exit of the trolley and the lifting and lowering of the furnace door, and has an interlocking device. When the furnace door is lifted or closed to a certain position, The trolley can be operated safely and reliably.
