Vacuum Furnace For Metal Heat Treatment

Vaccum Furnace

This furnace is pre-vacuum furnace for heat treating high quality mechanical parts of high speed steel, die steel, stainless steel, high alloy steel, titanium alloy etc.. 

Comparison of vacuum heat treatment and protective atmosphere heat treatment process:

1.Vacuum heat treatment: no oxidation, no decarburization

2.Protective atmosphere heat treatment: oxidation and decarburization are difficult to control

Vacuum Furnace 

application for annealing, hardening, air queching and tempering

Vacuum Furnace

bright heat treatment for high speed steel, die steel, stainless steel, high alloy steel, Ti-alloy etc.

Applications:

Most tool and die steels such as H13, D2, C12MoV, SKD61, SKD11, S-136, high-speed steel, 4Cr13, etc.

Description:

This Vacuum heat treatment furnace has the following advantages:

1. Achieve non-oxidation and non-decarburization heating: Since the molds are heated in a vacuum state, the oxygen partial pressure of the residual gas is extremely low, the surface is not oxidized, decarburized, and does not form any toxic products.

2. Small deformation and uniform hardness: Because vacuum heating mainly relies on heat radiation at high temperature, low-temperature convection is weak, so heating is slow, the temperature difference between the surface and the core of the workpiece is small, the expansion and contraction is more uniform, and the thermal stress caused is small, thereby reducing The final deformation of the workpiece.

3. Improve the plasticity and strength of the workpiece: The solid metal is heat-treated under vacuum, and the surface has degassing effect, thereby improving its plasticity and strength.

Vacuum heat treatment has the following advantages:

◇ Achieve non-oxidation and non-decarburization heating: Since the mold is heated in a vacuum state, the oxygen partial pressure of the residual gas is extremely low, the surface is not oxidized, decarburized, and does not form any toxic products.

 ◇ Small deformation and uniform hardness: Because vacuum heating mainly relies on heat radiation at high temperature, low temperature convection is weak, so heating is slow, the temperature difference between the surface and the core of the workpiece is small, the expansion and contraction is more uniform, and the thermal stress caused is small, thereby reducing The final deformation of the workpiece.

◇ Improve the plasticity and strength of the workpiece: The solid metal is heat-treated under vacuum, and the surface has degassing effect, thereby improving its plasticity and strength.

◇ Clean the surface of the workpiece: The grease attached to these objects in vacuum belongs to the common aliphatic group, which is carbon, hydrogen, oxygen compounds, and has a high vapor pressure. It is volatilized or decomposed when heated in a vacuum, and then is pumped off by the vacuum pump to make the surface of the workpiece Purification.

Application scope:

Most tool and die steels such as H13, D2, C12MoV, SKD61, SKD11, S-136, high-speed steel, 4Cr13, etc.

Suitable process:

Vacuum quenching and vacuum tempering of tool and die steel; solid solution and annealing of stainless steel and titanium alloy; strengthening treatment of high-speed steel; powder steel sintering; vacuum stress relief annealing of tool and die.

typical application: 

Die-casting molds, cold punching molds, extrusion molds, feed molds, plastic molds, tools and other types of molds.

Scope of application:

 Vacuum quenching: suitable for hot work and cold work die steels with high hardenability.

 Vacuum oil quenching: suitable for all kinds of hot work and cold work die steel.
