Vacuum Brazing Furnace ( heat-resistant steel hot field )

Introduction of Vacuum Brazing Furnace

The vacuum brazing furnace, featuring a heat-resistant steel hot field, is designed for high-precision brazing applications where temperature uniformity and clean processing environments are essential. With a maximum operating temperature of up to 750℃. It is particularly suitable for welding heat-resistant steel. It mainly uses a vacuum environment to improve welding quality and ensure that oxidation and contamination during the welding process are minimized.

Features

1. Construction and Heating System

The furnace features a stainless steel chamber and utilizes electric heating alloy tubes, with the maximum temperature reaching up to 750°C. The heating is achieved through ring-shaped alloy tubes, providing high uniformity with temperature variations within ±5°C.

2. User Interface and Control System

The furnace is equipped with a high-definition touchscreen interface and an operating system developed in-house. It also includes a PLC (Programmable Logic Controller) automatic control system for precise and reliable operation.

3. Vacuum System

The clean stainless steel chamber is complemented by a vacuum system consisting of a mechanical pump and a diffusion pump, achieving an ultimate vacuum of up to 7x10⁻³ Pa (under unloaded, cold conditions).

4. Economic Efficiency

Compared to molybdenum foil vacuum furnaces, this electric furnace offers lower power consumption and cost, making it a practical and economical choice for low-temperature brazing applications.
