Chain-type aluminum bar forge-heating furnace is continuous heating furnace. It consists of heating furnace, driving mechanism, hot air circulation device and electrical control system. It requires operator to put aluminum bars horizontally on the two chains of feeding port, then aluminum bars are continuously conveyed into heating furnace by electric-driven chains for heating to reach required temperature, then manually open furnace door and click the switch for automatically discharging materials. This equipment is mainly used for forging and before-extrusion heating for aluminum bars.
