Vacuum Varying Pressure Nitriding Furnacea To Nitriding Extrusion Die

Pit type gas nitriding furnace is mainly used for carbon steel parts gas nitriding, mould quenching and other heat treatment . The furnace is equipped with drip device, also can be used for gas nitrocarburizing (soft nitriding) heat treatment. When doesn’t feed into ammonia gas and use drip devices, can be used as a general well type tempering furnace.

Vacuum variable pressure nitriding furnace is widely used in surface nitriding treatment of metal molds, tools, shafts, gears and steel parts, commonly used gas controllable nitriding (hard nitriding), nitrocarburizing (soft nitriding), etc. Process, equipped with fast cooling fans, can shorten production cycle, temperature uniformity and composite lining.

The pit gas nitriding furnace produced is suitable for hard nitriding and soft nitriding of various aluminum profile molds H13, extrusion dies, screws, screws and other parts.

Product Effect

After nitriding, a white nitrided layer is formed on the surface of the workpiece, which makes the workpiece obtain higher hardness, higher wear resistance, higher corrosion resistance and longer service life.

Furnace Shell

Welded by A3 high-quality carbon steel and made into a single layer shell, thickness is 6mm. Have sufficient strength and rigidity, can bear the weight of the furnace and workpieces, and keep geometric shapes Non-deformation.

Furnace Lining

Use of lightweight refractory brick and aluminum silicate fiber cotton, composed of thermal insulation fireproof layer and insulating layer, heat insulation refractory layer using high strength lightweight and high alumina refractory bricks, are according to the laying process standard execution, has good heat insulation performance, service life in more than 5 years.

Furnace Tank

Adopt for high quality 321 heat resistant stainless steel plate, thickness is 8 mm . Has long service life under rated temperature. The furnace pot rests on the bottom to increase the atmosphere inside of the furnace and increase the pot service life.
