Steel belt conveyor furnaces are tailored to PM industry for the reduction of Fe, Cu, Co, Mo and W metal powders from respective oxides, also for the calc-inations and fine reduction of oxilate, APT and other metal salines.      The equipment has a large output and a relatively simple structure and it is easy to adjust process parameters and control product quality, so it has been used an upgrading equipment replacing the old generation of furnaces, such as two-tube, four-tube and multi-tube reduction furnaces. It consists of load, reduction, slow cooling, cooling and unload sectors.
