What Are The Types of Vacuum Furnaces? What Is It Used For?

Vacuum furnace can achieve vacuum quenching and tempering, vacuum annealing, vacuum solution and aging treatment, vacuum sintering, vacuum chemical heat treatment and vacuum coating and other processes, so the vacuum furnace can achieve complex processes that other heat treatment equipment can not handle.

Vacuum furnaces are classified into vacuum brazing furnace, true air quenching furnace, vacuum sintering furnace, vacuum annealing furnace, vacuum tempering furnace, vacuum oil quenching furnace, vacuum carburizing furnace and other types. Let's take a look at what different vacuum furnace types are used for, and what are the benefits of using vacuum furnaces for workpiece handling!

1 Use of vacuum brazing furnace

Vacuum brazing furnace is mainly used for aluminum alloy heat exchanger and other aluminum products vacuum brazing, stainless steel, titanium alloy, hard alloy, superalloy, non-ferrous metal brazing and high speed steel, tool steel, bearing steel, stainless steel and other materials vacuum tempering, as well as non-ferrous metal aging and annealing treatment and stainless steel heat exchanger, oil cooler, stainless steel vacuum brazing cup.

2 Use of real air quenching furnace

Real air quenching furnace is mainly used in high pressure gas quenching of high speed steel, tool steel, die steel, alloy structural steel and other materials. It can also be used for high temperature brazing and solid solution of stainless steel materials; Sintering and aging treatment of powder materials. At the same time, it also has fast cooling function during annealing solution.

3 Use of vacuum sintering furnace

Vacuum sintering furnace is filled with hydrogen after vacuum protection state, using the principle of medium frequency induction heating, so that the tungsten crucible in the coil to produce high temperature, through thermal radiation conduction to the work, suitable for scientific research, military units on refractory alloy such as tungsten, molybdenum and its alloy powder forming sintering. It is also divided into two kinds of horizontal vacuum sintering furnace and vertical vacuum sintering furnace. The place where the electric furnace is installed should meet the requirements of vacuum health, the surrounding air should be clean and dry, and there are good ventilation conditions, and the working site is not easy to raise dust.

Vacuum sintering furnace is mainly used for the sintering process of semiconductor components and power rectifier devices, which can be vacuum sintering, gas protection sintering and conventional sintering. It is a novel process equipment in the semiconductor equipment series. It has novel design concept, convenient operation and compact structure, and can complete multiple process processes on the platform equipment. Can also be used in other areas of vacuum heat treatment, vacuum brazing and other processes.

4 Use of vacuum annealing furnace

Vacuum annealing furnace is mainly suitable for stainless steel drawing parts such as water heating equipment, no oxidation. Vacuum annealing furnace. With high productivity. After treatment, the surface of the product, bright no oxidation and other points, widely used in stainless steel bearings, tools, self-tapping self-drilling, rust steel screws and other fields, vacuum annealing furnace can also be used in the protective atmosphere, less pollution, the role of vacuum is mainly for high-precision metal components of the precision parts, to avoid contact with complex gas components under high temperature conditions set up a barrier, can also be used as atmosphere annealing.

5 Use of vacuum tempering furnace

Vacuum tempering furnace application requirements after tempering parts surface bright, no oxidation color, can be used in high temperature tempering of die steel, high temperature alloy, elastic alloy, copper alloy, titanium alloy, copper and copper alloy stress relief and softening annealing, and can double fast cooling function.

6 Use of vacuum oil quenching furnace

The vacuum oil quenching furnace is suitable for the vacuum heat treatment of die steel, spring steel, stainless steel, bearing steel, high temperature alloy steel, and can also be annealed. Its main points are a wide range of applicable materials, strong hardenability, low cost, and reusable quenching oil. The shortcomings are: The amount of deformation is relatively large, and the workpiece needs to be cleaned later. The vacuum oil quenching furnace can be divided into two chamber furnaces and three chamber furnaces.

7. Use of vacuum carburizing furnace

The vacuum carburizing furnace can flexibly implement a variety of heat treatment processes, such as vacuum carburizing, vacuum carburizing, vacuum carburizing + oil quenching, vacuum carburizing + gas quenching, and vacuum furnace functions. It can also be used for heat treatment of various materials and parts in industrial fields. Such as 12Cr2NI4A, 12CrNi3A and other high-alloy carburizing carbon steel carburizing and carburizing hardening, 20CrMnTi and other structural steel carburizing and carburizing hardening, 1Cr13 and other stainless steel carburizing and carburizing hardening, Quenching and annealing of H13, W6Mo5Cr4V2 and other tool steel, gear parts, shaft sleeve parts, precision bearings, oil pump nozzle mechanical parts, precision mechanical parts, etc.
