Pit type vacuum quenching furnace with atmosphere protective
Brief
RJ2 series pit type vacuum quenching furnace with atmosphere protective isnational standard energy-saving batch type heat treatment furnace, heat treatment temperature can reach 850℃-1200℃,mainly used to rod, long axis,roll, 45 steel, stainless steel and other metal materials and mechanical parts for quenching heat treatment. Workpiece are vertical lifting and quenching,not easy to deformation.
Structure
Pit type vacuum quenching furnace with atmosphere protective consist mainly composed of furnace shell, lining, heating device and temperature control and other major parts, furnace body is cylindrical deep well, workpiece is installed vertically furnace inside for heating, 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.
Pit type 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.
