RJ2 series pit type tempering furnace is batch type heat treatment furnace, using the high or low temperature tempering after quenching, mainly used to rod, long axis, plate, shaft and other metal materials and mechanical parts. Electricity or gas can be used for heating, use electricity as heat source, is called the pit type resistance furnace, also can form a complete set of heat treatment production line with pit type tempering furnace, quenching tank, washing machine.,etc, This furnace is placed under the ground plane in the workshop, can also be placed above the ground plane, or ground level fluctuation in each half.
Structure
Pit type tempering furnace is mainly composed of furnace shell, furnace lining, furnace cover and lifting device, heating device, loading frame and electrical control cabinet.,etc.
Advantages
1.Furnace body is cylindrical deep well, parts is installed vertically furnace inside for heating, not easy to deformation.
2.Good sealing and furnace temperature uniformity.
