950℃ Energy-saving Box-type Resistance Furnaces 

Summary:
            RX3 series furnaces is composed of shell,lining,heating elements.door and electric cabinet. The furnace lining is built of 0.6 ultra-light refractory bricks and refractory fibber,The heating elements is made of spiral shape high resistance alloy wires, placed in the both sides of the furnace hearth and hearth bottom. Workpieces are put on the furnace bottom plate, furnace door can be lifted or falled through hand wheel. A travel switch is installed above the door, when the door opens power is cut off so as to ensure the safety of operating personnel.

APPLICATION:
             The series 950℃ box-type resistance furnace is a cycle type furnace, mainly used for metal parts in the air to normalize,anneal,quench.
