Product Description:

The carbothermic reaction furnace is a kind of electric resistance tunnel furnace, which can be customized according to the user's production volume. The tunnel furnace provides a high temperature environment with a continuous protective atmosphere and can be equipped with production line operations. It has the characteristics of high production efficiency, manpower saving and stable carbonization quality. According to different processing requirements of various products, pre-stored more than 15 sets of parameters, through PLC intelligent control system, inverter stepless speed change, automatic operation.
