The RCM mesh belt quenching furnace is a continuous operation heat treatment production line. It uses intermittent forward mesh belt to transport workpieces, and through a temperature controlled heating zone, they fall into the quenching tank and are taken out by a hoist, thus completing the process of workpieces. It is a heat treatment furnace with continuous automatic control. During the heat treatment process, the workpieces are heated smoothly and evenly through the furnace without any collision with each other. This furnace has the advantages of high automation, easy parameter adjustment, low labor intensity, no environmental pollution, and energy conservation. It can be widely used for heat treatment of "medium" and "small" workpieces produced in large quantities in light industry machinery, textile machinery, weapons industry, and electromechanical industry.
