Vacuum Furnace Desgin

SIMUWU is a professional vacuum furnace design manufacturer, has complete processing and inspection equipment. Professional production design vacuum sintering furnace, vacuum smelting furnace, vacuum heat treatment furnace, vacuum brazing furnace, high-speed steel, high-hard alloy steel and various mould steel and other vacuum heat treatment furnace equipment.

SIMUWU has a group of senior engineers, and has carried out many technical cooperation with domestic vacuum furnace R&D units. It has introduced advanced theory and technology from abroad for many times, It has developed into a R & D and manufacturing enterprise with hundreds of employees.

Vacuum furnace plays an irreplaceable role in mould production, mainly used for ceramic firing, vacuum smelting, degassing of electric vacuum parts, annealing, brazing of metal parts, and ceramic-metal sealing.

The structure of vacuum furnace, heating process, temperature control and atmosphere in the furnace will directly affect the quality of processed products. In the forging furnace, increasing the heating temperature of metals can reduce the deformation resistance, but too high temperature can cause grain growth, oxidation or over-burning, which seriously affects the quality of the workpiece. In the heat treatment process, if the steel is heated to a point above the critical temperature and then suddenly cooled, the hardness and strength of the steel can be increased; if the steel is heated to a point below the critical temperature and slowly cooled, the hardness of the steel can be reduced and the toughness can be improved.

In order to obtain workpieces with precise size and smooth surface, or to reduce metal oxidation in order to protect dies and reduce processing allowance, various kinds of less oxidation-free heating furnaces can be used. In an open flame furnace with little or no oxidation, reductive gases are produced by incomplete combustion of fuel, in which the oxidation burning rate can be reduced to less than 0.3% by heating the workpiece.
