Features：

- The large vacuum nitriding furnace is a standard energy-saving cycle nitriding furnace. It is mainly used for gas nitriding heat treatment of various large workpieces and long-axis workpieces.

Structure Description:

- Gas nitriding furnace adopts energy-saving furnace lining double water-cooled furnace lid, vacuum rubber seal and temperature control in upper and lower two zones or multiple zones. The nitriding furnace heat preservation, furnace temperature uniformity, sealing property and nitriding speed are greatly improved, and the furnace type is consistent with international standards. The outer casing of this series of well gas nitriding furnace is made of steel plate and section steel. The lining is made of ultra-lightweight, high-strength energy-saving refractory brick. The outer layer of the furnace lining is sandwiched with aluminum silicate fiber and filled with expansion and thermal insulation powder. The heating element is spirally wound by a high-temperature resistance wire, mounted on the lining of the lining, and a stainless steel vacuum tank is placed in the furnace. A double-headed stainless steel drip chamber is installed on the furnace cover for instilling methanol to make the temperature atmosphere in the nitriding furnace uniform. The furnace cover is provided with a sampling tube, an exhaust pipe, and an input pipe at the upper part of the side wall of the furnace tank for inputting ammonia gas, and the furnace tank and the furnace cover are sealed by water-cooled vacuum rubber and equipped with a compression screw. The exhaust gas in the gas nitriding furnace is discharged outside the furnace through the exhaust pipe.
