Pit type steel tempering furnace
Brief
RJ2 series pit type steel tempering furnace is batch type heat treatment furnace, tempering temperature is 650℃, using the high or low temperature tempering after quenching in a relatively sealing state cavity. Pit type furnace is usually placed under the ground plane in the workshop, also is placed above the ground plane, or ground level fluctuation in each half.
Application field
Mainly used to rod, long axis, plate, shaft and other metal materials and mechanical parts.
Structure
Pit type steel tempering furnace is mainly composed of furnace shell, lining, heating device, muffle tank , loading frame. furnace cover and hoisting mechanism of furnace roof.
Advantages
Furnace body is cylindrical deep well, workpiece is installed vertically furnace inside for heating, not easy to deform.
Pit type steel tempering furnace can also be used for mechanical parts for tempering ,annealing, normalizing, carburizing and carbonitriding heat treatment, etc, electricity or gas can be used for heating, with electricity as heat source, is called the pit type resistance furnace, can form a complete set of heat treatment production line with pit type tempering furnace, quenching tank, washing machine and other equipment.
