Features：

- As a standard nitriding heat treatment equipment, the pit nitriding furnace is mainly used for gas nitriding of metal parts such as various mechanical parts, auto parts and molds. The pit nitriding furnace generally adopts gas nitriding as the main nitriding method, and the furnace is equipped with a high temperature resistant stainless steel vacuum tank. When used, the vacuum tank is vacuum pumped to a vacuum state, and then the heated workpiece is subjected to gas nitriding. deal with.

- The outer casing of the pit nitriding furnace is welded by steel plate and section steel. The lining is made of ultra-lightweight, high-strength energy-saving refractory brick, and the outer layer of the lining is sandwiched with high-purity ceramic fiber composite insulation. The heating element is made of a long-life design high-temperature resistance wire with a stainless steel vacuum tank in the furnace. In order to improve the sealing and heat insulation performance of the pit nitriding furnace, a double water cooled furnace can lid, a vacuum rubber seal and a compression screw are installed. . A double-headed stainless steel drip chamber is installed on the furnace cover for instillation of methanol, which is easy to operate and safe. The furnace cover is provided with a sampling tube, an exhaust pipe, and an input pipe on the upper side of the side wall of the furnace tank for inputting ammonia gas, and a special exhaust pipe is installed.
