Vacuum Heat Treatment Furnace Types
External vacuum heat treatment furnace External vacuum heating furnace is an earlier product of vacuum heating furnace. Its structure is relatively simple and water cooling device is lacking, which results in that the working temperature of external vacuum heating furnace can not be too high, oth...
Vacuum heat treatment furnace
Vacuum heat treatment furnace is a fast developing heat treatment technology in recent years. It has many advantages, such as good quality, good energy saving effect and no pollution. It has been widely used in industrial production process. Vacuum heat treatment technology is the combination of ...
Vacuum continuous brazing furnace
Multi-chamber continuous vacuum furnace is mainly used in brazing of aerospace, heat exchanger, electric vacuum industry and other metal parts. Multi-chamber continuous vacuum furnace is composed of feeding chamber, preheating chamber, high-temperature chamber, cooling chamber, discharging chambe...
12 bar vacuum quick quenching furnace
RVGQ-669 12 bar vacuum quick quenching furnace is a cold wall resistance heating furnace, with horizontal cubic heating zone, using convection heating and high pressure gas quenching.The heating element and insulation layer are graphite materials, with the highest heating temperature of 1350℃ and...
Vacuum nitriding furnace
Vacuum nitriding furnace working principle: Vacuum nitriding can be carried out by injecting ammonia gas into the vacuum furnace, which is similar to pulse vacuum carburizing, i.e. the workpiece begins to suction after being loaded into the vacuum furnace. When the vacuum degree reaches a set val...
12 bar gas quenching furnace
Vacuum gas quenching furnace decarbonization in vacuum state, small deformation. The surface is bright and the performance is improved. No decarbonization/oxidation. Mainly used in high-pressure gas quenching of high-speed steel, tool steel, die steel, alloy structural steel and other materials. ...
Stainless steel, Oil cooler, heat exchanger brazing
Before stainless steel, oil cooler, heat exchanger brazing, generally do not need to carry out special cleaning, as long as the implementation of the oil removal process can be. The selection of vacuum should not be too high, generally x 10-2pa above.High vacuum degree will lead to the volatiliza...
40Cr steel and carbide brazing
Carbide gear hobbing cutter is widely used in production, which can be used to process various kinds of gear, and can be used to replace tooth grinding process when hard gear is processed.This hobbing cutter is made of YT50 carbide and 40Cr medium carbon steel by vacuum brazing process. 1. Gear h...
Vacuum brazing of aluminum and aluminum alloy
Compared with other metals, aluminum and aluminum alloy is difficult to braze, and its welding performance is poor. The main reason is that aluminum has A great affinity for oxygen, and it is easy to form A dense and chemically stable aluminum oxide film with A high melting point (~ 2050^C) on th...
Vacuum brazing of carbon steel and low alloy steel
Vacuum brazing characteristics Carbon steel and low alloy casks are the most widely used materials in various industrial sectors.The ease of brazing of such materials depends first on the oxide composition and structure formed on the surface.When heated, four oxides of iron tend to form on the st...
