In high-end material processing, vacuum furnace performance directly dictates final material quality.

The BR-QCL Vacuum High-Pressure Gas Quenching Furnace, a high-end vacuum quenching furnace with integrated core technologies, features precise temperature control, efficient cooling, and reliable safety design.

Widely applicable to aerospace, precision machinery, and electronics industries, it is a key asset for enhancing product competitiveness.

1. Equipment Composition and Standard Guarantee

Core Modules Overview

As a professional vacuum furnace, the BR-QCL Vacuum High-Pressure Gas Quenching Furnace consists of multiple core modules.

These modules include the vacuum furnace main unit, vacuum system, water cooling system, pneumatic system, gas filling system, electric control system, and external furnace transport vehicle.

Dual Standard Compliance

All technical indicators strictly comply with dual standards: both Chinese industry standards and the manufacturer's qualified factory standards.

This provides a fundamental guarantee for the stability of equipment operation and the reliability of processes.

2. Precise Temperature Control, Uniform Thermal Field

Control System Configuration

Precise temperature control and a uniform thermal field are two of the main advantages of this vacuum quenching furnace.

The equipment adopts a 15-inch touch screen for full automatic control. It is equipped with a closed-loop control system composed of thermocouples, temperature controllers, thyristor voltage regulators, and heaters.

The temperature control accuracy is as high as ≤±1℃, and the temperature field uniformity can reach ±5℃, ensuring uniform temperature distribution during material heating.

This precise temperature control capability can effectively avoid performance defects caused by local overheating or insufficient temperature.

Temperature & Heating Parameters

The temperature control point uses S-type temperature measuring elements, which can work stably for a long time in a vacuum environment of 500-1300℃.

The heating rate is adjustable from 0-20℃/min, which can accurately match the heat treatment process requirements of different materials.

Energy-Saving Heating Mode

At the same time, the heating system adopts a low-voltage and high-current power supply mode. It introduces electric power into the in-furnace heater through copper bars and water-cooled electrodes, ensuring heating efficiency while effectively reducing energy consumption.

3. Efficient Vacuum, Flexible Gas Filling

Vacuum System Performance

The efficient vacuum and flexible gas filling system creates a high-quality environment for material processing in the vacuum gas quenching furnace.

The equipment can be customized with a low-vacuum or high-vacuum system according to actual needs. Among them, the ultimate vacuum degree of low vacuum can reach 5×10⁻¹Pa, and the ultimate vacuum degree of high vacuum is better up to 7×10⁻⁴Pa.

After fully baking the empty furnace in a cold state, the pressure rise rate of the equipment is ≤0.67Pa/h.

It only takes ≤20 minutes from opening the main valve to reaching the working vacuum degree, and the vacuum pumping efficiency is at the leading level in the industry.

Pressure Adjustment & Gas Filling Control

The partial pressure range supports 10-800Pa adjustment, and the maximum absolute pressure in the furnace can be selected up to ≤10bar, which can adapt to process scenarios with different pressure requirements.

A PLC fully automatically controls the gas filling system. It can realize fast filling, micro-filling, and automatic maintenance of in-furnace air pressure functions, accurately control the gas filling process, and ensure the quenching effect of the vacuum gas quenching furnace.

4. Efficient Cooling, Improving Material Performance

Cooling System Configuration

The efficient cooling system further improves the process adaptability of the vacuum furnace.

The equipment is equipped with a built-in high-power water-cooled motor and a high-efficiency fan at the tail, which can generate a strong air flow to provide power support for rapid cooling.

At the same time, it is matched with a heat exchanger made of copper finned tubes, adopting a staggered water inlet method of rear-in and front-out, which greatly improves the heat exchange efficiency.

Customizable Cooling Parameters & Design

The cooling speed and the number of air ducts can be customized according to user needs to adapt to the cooling requirements of different materials.

The scientific design of the deflector ensures smooth gas flow, realizes rapid and uniform cooling of materials, and effectively improves the hardness and toughness of materials.

5. Safety Protection and Intelligent Electric Control, Ensuring Stable Operation

Intelligent Electric Control Features

Reliable safety design and an intelligent electric control system ensure the stable operation of the vacuum quenching furnace.

The electric control system is equipped with a user-friendly graphical man-machine interface, which can dynamically display the process and movement status in real time.

The massive storage space has great expansion potential.

The system also sets multiple operation permissions and is equipped with a password protection function, which can effectively prevent misoperation.

Safety Protection Mechanisms

The vacuum system has a built-in self-protection logic interlock system. When the power is cut off, the valve will automatically close to ensure that the vacuum state in the furnace is not affected.

The furnace body features a double-wall water-cooled structure, incorporating various openings such as vacuum ports, electrodes, thermocouples, and safety valves, to ensure process expandability and operational safety.

Supporting Equipment Solutions

In addition, supporting equipment such as tempering furnaces, cooling towers, and external furnace trucks can be customized or purchased on behalf of users according to needs, realizing a one-stop solution.

Customized Solutions, Empowering High-End Manufacturing

With customized design as its core advantage, the BR-QCL Vacuum High-Pressure Gas Quenching Furnace delivers stable process quality and low operational risks, providing reliable heat treatment solutions for both conventional and special material processing to boost high-end manufacturing development.
