Surface Treatments Vacuum Furnace
A vacuum furnace is a specialised type of industrial furnace used for various heat treatments in a vacuum or controlled atmosphere environment. Vacuum furnaces are designed to operate at high temperatures, typically up to 2400°F (1315°C), to create a vacuum or controlled atmosphere for processing a variety of materials.
In surface treatment applications such as carburizing and nitriding, metal parts are heated in a vacuum furnace to a specific temperature and then exposed to a carbon or nitrogen-rich atmosphere. This process improves the hardness, wear resistance, and corrosion resistance of the parts, making them ideal for use in high-stress applications.
Function
It provides controlled heating and cooling cycles to achieve desired material properties.
Configuration
The furnace typically includes a vacuum chamber, heating elements, a gas delivery system, and a control system.
Features
The furnace may have a diffusion pump for high vacuum, a gas quenching system for quick cooling, and a computerised control system for exact temperature and gas management.
Temperature Range
The furnace can typically achieve temperatures as per the process requirement.
Heating Rate
The heating rate can be controlled to achieve a specific temperature profile for the surface treatment process.
Capacity
The furnace can process multiple parts at once, depending on their size and the capacity of the vacuum chamber.
Heat Source
Electric heating elements, usually made of graphite or tungsten, are used to heat the parts in the vacuum chamber.
Power Requirement
The power requirements for the furnace depend on the required technical parameters.
Atmosphere
The furnace operates in a vacuum environment, with controlled amounts of gases, such as nitrogen or argon, introduced for surface treatments.
