Vacuum Heat Treat Sintering Brazing Furnace

Introduction

A vacuum brazing furnace is a type of industrial furnace used for brazing, a metalworking process that joins two pieces of metal using a filler metal that melts at a lower temperature than the base metals. Vacuum brazing furnaces are typically used for high-quality applications where a strong, clean joint is required.

Vacuum brazing furnaces operate by creating a vacuum inside the furnace chamber, which removes oxygen and other gases that can interfere with the brazing process. This creates a clean environment that promotes strong, reliable joints. Vacuum brazing furnaces are also capable of achieving very high temperatures, which allows for the brazing of a wide variety of metals, including stainless steel, titanium, and aluminum.

Details & Part

Applications

Vacuum brazing furnaces are widely used in various industries and applications due to their ability to create strong and leak-proof joints. Some of the main application areas include:

• Heating and cooling assemblies
• Micro-channel heat exchangers
• Aircraft components
• Sensors
• Medical devices
• Structural components
• Other thermal products

Features

The vacuum brazing furnace offers numerous benefits that enhance its functionality and value for customers:

• Exceptional temperature uniformity: The furnace's design ensures uniform heating throughout the chamber, resulting in consistent and precise brazing results.
• Efficient heating system: The furnace utilizes a high-performance heating system that rapidly reaches and maintains the desired temperature, reducing cycle times and increasing productivity.
• Advanced vacuum system: The furnace is equipped with a sophisticated vacuum system that effectively removes oxygen and other contaminants from the chamber, ensuring a clean and controlled brazing environment.
• User-friendly interface: The furnace features an intuitive and easy-to-use interface that simplifies operation and monitoring, minimizing the need for extensive training.
• Robust construction: The furnace is constructed from durable materials and components, ensuring longevity and reliability in demanding laboratory environments.

Principle

The vacuum brazing furnace is a horizontal furnace body, composed of a furnace shell, furnace lining, heating element, furnace tank, material tray, vacuum system, and electronic control system. The furnace shell is welded from carbon steel plates and section steel. It is lined with high-quality insulation bricks and refractory bricks and is constructed in three zones. The heating elements are made of iron-chromium-aluminum wire and are arranged in a spiral shape on the wire bricks on both sides and bottom of the furnace. The vacuum system uses a three-stage vacuum pump, which is composed of a vacuum unit, an oil diffusion pump, a Roots pump, a mechanical pump, a pneumatic baffle valve, and a manual butterfly valve.

Advantages

• High-quality joints with minimal voids and excellent mechanical properties
• No need for flux, which eliminates potential contamination and post-brazing cleaning
• Reduced oxidation and scaling, resulting in cleaner joints
• Precise temperature control, which allows for the joining of materials with different melting points
• Suitable for joining complex components and assemblies
• The environmentally friendly process with minimal waste generation
