Industrial vacuum furnace Manufacturers in China

Product Introduction

The industrial vacuum furnace is a professional equipment in the heat treatment industry. The furnace chamber is a closed space that utilizes the characteristics of the vacuum environment to create an oxygen-free environment. Metal parts are treated with hardening, brazing, tempering, and other processes in a vacuum oxygen-free environment.

A vacuum furnace usually consists of a furnace body, a water cooling device, a control system, a vacuum system, a heating device, a transformer, and other parts. Vacuum furnaces with different production processes may have some differences in details.

The current vacuum furnace control system uses PLC as the command execution processor. Users can program logic commands to set different product heat treatment processes. The built-in storage can save these command programs, providing reliable reference value for continuous improvement, optimization, and product quality provision.

Industrial vacuum furnace advantage

Temperature uniformity

Independent temperature control in multiple regions to achieve high-precision temperature uniformity, up to ± 1 ℃

Intelligent control system

PLC centrally controls the vacuum furnace, and users can achieve logic command programming control through the touchscreen.

Equipment fault identification

If there is a malfunction during the heat treatment, the Industrial vacuum furnace will immediately sound an alarm and provide suggestions.

Nitrogen gas protection

Some heat treatments need the vacuum furnace to be filled with nitrogen gas, which has this function.

Loading vehicle

It has a special mechanized loading vehicle, and metal parts can be easily removed from the cabin.

Closed water cooling

Water cooling devices and diffusion tubes achieve rapid cooling, improving work efficiency.

Industrial vacuum furnace advanced features

There are 8 thermocouple inputs and multi-channel temperature recorders on the furnace shell to control the uniformity of temperature, with a maximum accuracy of 0.5 ℃

There are multiple layers of 304 stainless steel plates for insulation inside the furnace, with ceramic gaskets in the middle of each layer of stainless steel to isolate it from corrosion by nickel, copper, and other metal elements.

The furnace door has a rotating locking device driven by a cylinder. When the furnace door is closed without locking, the industrial vacuum furnace will issue a warning,

Every component of the vacuum furnace is scientifically designed, and if it is damaged during use, engineers can easily replace it with a spare part.

The function of each part

Vacuum furnace body

Vacuum furnace body

This is the workspace of the vacuum furnace, where all parts must undergo heat treatment. Each vacuum furnace has a different space size, and users can purchase the appropriate size according to their production needs.

Usually, the furnace body consists of a furnace shell, insulation materials, windows for observing the interior, cooling devices, heating systems, insulation, nitrogen protection, and other components,

The furnace door is a key part, and inert gas is fille into the furnace under a vacuum, which puts higher requirements on the sealing and pressure resistance of the furnace door. Therefore, the design of the furnace door will have an automatic locking device.

The function of vacuum pump

The vacuum unit of industrial vacuum furnaces is composing of multiple vacuum pumps, such as diffusion pumps, Roots pumps, slide valve pumps, and rotary vane pumps, which play an important role in delivering under different vacuum pressures.

When the vacuum furnace is preheated, the rotary vane pump starts working. It is small, lightweight, and has an excellent energy-saving effect in low vacuum environments.

The diffusion pump starts working when high vacuum pressure is desired. It has a strong power output and can quickly reach the ultimate vacuum pressure. This pump is usually install in vacuum furnaces that require high vacuum heat treatment.

Water cooling device

Every industrial vacuum furnace is with a water cooling device, which serves to absorb the heat generated by the furnace body and maintain a safe temperature range,

Water cooling devices usually consist of water circulation pumps, cooling towers, water-cooled coils, and other parts. The water-cooling coils is install between the compartments of the furnace body,

so strict sealing tests are needs to ensure that the water-cooling tubes do not leak while manufacturing the furnace body.

Another function of the water cooling device is to cool down the vacuum furnace and improve work efficiency quickly.

Industrial vacuum furnace Applications

Almost all industries require vacuum furnaces to improve product quality and meet special application needs in modern industrial heat treatment production. Let’s give a few examples of the most widely used industries.

  1. Aluminum brazing

In modern industrial production, some specially structured aluminum parts require multiple parts to be weld. Ordinary welding machines cannot meet this special requirement, so brazing and vacuum furnaces play their roles.

For example, aluminum parts for automobiles, special parts for aerospace, industrial heat exchangers, and other complex structural parts require brazing vacuum furnaces for oxygen-free vacuum welding.

  1. Quenching and tempering

To fully utilize the performance of metal parts, it is necessary to quench and harden them during the manufacturing process, and a quenching vacuum furnace is the best solution for this process,

  1. Powder metallurgy

Some powder metallurgy parts need to be sinter in a vacuum environment to ensure the performance and quality of the parts and to avoid oxidation and contamination that can damage the properties of the metal

  1. .Surface treatment

This heat treatment is a process that improves the surface of metal parts to enhance their durability and wear resistance, usually through carburizing or nitriding.
