 Glow Ion Nitrogen Atmosphere Bright Annealing Vacuum Heat Treatment Furnace for Crankshaft

1. Application Scope of Pit Gas Nitriding Furnace

It is mainly used for nitriding heat treatment of various steel mechanical parts, such as crankshafts, piston rods, steel cylinders, brake pads, molds, etc. Thereby improving the surface hardness and wear resistance of the workpiece.

2. Structural characteristics of pit gas nitriding furnace

The well-type gas nitriding furnace is an energy-saving gas nitriding furnace, which consists of an energy-saving furnace lining, a water-cooled sealed anti-corrosion motor, a vacuum rubber sealing ring, and a thyristor control cabinet. The shell of this series of pit gas nitriding furnace is welded by steel plate and section steel. The furnace lining is made of ultra-light, high-strength 0.6g/cm3 energy-saving refractory materials. The outer layer of the furnace lining is sandwiched with aluminum silicate fibers, and the middle is filled with expanded vermiculite powder for heat preservation. The heating element is spirally wound by high-temperature resistance wire, installed on the lining brick, and the furnace is equipped with a stainless steel tank. The furnace cover is provided with a sampling pipe and an exhaust pipe. Nitrogen enters the furnace bottom through a nitrogen inlet pipe on the side wall of the furnace. The furnace chamber and furnace cover are sealed with water-cooled vacuum rubber.
