Pit type nitriding furnace
The pit type nitriding furnace furnace produce process is:wires load in one vessel with cover and heating in furnace body then they(vessel and cover) lift out of body put side for cooling, another vessel with cover is loading and
heating in furnace body. Total produce process vessels are sealed with cover and connected to electricity, gas and thermocouple
Mainly applied for metal wire heat treatment in protective atmosphere(75% Hydrogen, 25% Nitrogen, produce with Ammonia decomposition furnace(user owned)).
Rated temperature: 1150 ℃
Furnace lining:aluminum silicate fiber insulation material
Cover lift: lift by Crane(user owned)
Vacuum pump:Two stage mechanical rotary vane vacuum pump
seal fan:one set, made by stainless steel.
Vessel:2 sets,made by stainless steel,casting, material as 0Cr25Ni20/GH747
temperature control area:3 area
protective atmosphere:75% Hydrogen, 25% Nitrogen, produce with Ammonia decomposition furnace(user owned)
