There are many types of nitriding furnaces. Today we will first talk about gas nitriding furnaces, which use energy-saving furnace lining tank covers. The vacuum rubber seals in them can achieve temperature control, making the electric furnace heat preservation performance and furnace temperature uniform. And the sealing is better.
The shell of the gas nitriding furnace is welded by steel plates and shaped steel. The furnace lining is made of ultra-lightweight, high-strength and energy-saving refractory bricks. The outer layer of the furnace lining is sandwiched with aluminum silicate fiber, and then filled with expanded vermiculite powder for heat preservation. The heating element is spirally wound by high-temperature resistance wire and installed on the bricks of the furnace lining. A stainless steel furnace tank is installed in the furnace.
A double-head stainless steel dripper is installed on the furnace cover for dripping methanol to make the temperature and atmosphere in the furnace uniform. The furnace cover is equipped with a sampling pipe, an exhaust pipe, and an input pipe on the upper part of the side wall of the furnace tank for ammonia gas input. The furnace tank and furnace cover are sealed with water-cooled vacuum rubber and are equipped with compression bolts. The exhaust gas in the furnace is discharged out of the furnace through the exhaust pipe.
The lifting and lowering of the nitriding furnace tank cover adopts an electro-hydraulic device. The lifting and lowering of the furnace tank cover is smooth and without jitter. The electric furnace is equipped with a chain protection device to prevent malfunctions and accidents due to misoperation. The electric furnace is equipped with a rapid cooling device, which can be used as needed. Rapid cooling; no pollution.
Because the nitriding furnace is protected by nitrogen, it will not deform or be oxidized when working. It also has the characteristics of saving gifts. The furnace is also equipped with a hot air circulation device, which can make the temperature uniform and extend the service life. will be extended.
