Application

RJ2 Series Pit hardening furnace is the national standard energy-saving cycle operation shaft furnace, heat treatment or quenching temperature 850-1200 ℃, mainly for shaft parts, rod-shaped workpiece, roll, 45 steel, stainless steel and other metal materials and mechanical parts of the quenching heat treatment purposes, vertical lifting quenching, the workpiece is not easy deformation, but also on the mechanical parts for annealing, normalizing heat treatment.

RJ2 ..-6 series Pit Furnace structure, the shell is made by a steel plate and steel cylindrical furnace. The inner surface of the lid made of stainless steel. Lining using ultra-light saving microporous insulating refractory brick building. Lining and the furnace shell sandwich home silicate fiber cotton insulation, insulation powder expansive space filled. Resistance wire used 0Cr25Al5 high resistance alloy wire wound into a spiral wire shelf mounted on brick hearth. Placed inside a stainless steel chamber loading basket. A lever manually lift the lid. In order to uniformly heat the workpiece, the lid is mounted on the shaft and blades made of heat-resistant stainless steel hot air circulation fan, the workpiece in the heating process, the hot air circulation furnace and down in order to ensure uniform heating of the workpiece. To ensure safe operation in the vicinity of the lifting mechanism is equipped with limit switch, this switch with the furnace control cabinet power interlock, lid off (work) power.When the lid is turned off limit switch that controls power, so the power supply and cut off the heating element in order to ensure safe operation. Pit Furnace factory supporting automatic temperature control cabinet, thermocouples.

Application:

Pit vacuum annealing furnace is the national standard energy-saving industrial furnace, mainly for various mechanical parts for vacuum annealing, widely used in a variety of metal materials, alloys, crystalline materials to stress annealing, bright annealing, vacuum degassing and so on. Through different configurations can also pass into the protective gas nitriding, carburizing.
