What is the temperature of a vacuum annealing furnace?

The temperature range of a vacuum annealing furnace varies depending on the equipment model, manufacturer, and application requirements. The following is a detailed summary of the temperature range for vacuum annealing furnaces:

1. High temperature furnace
Maximum temperature: Some vacuum annealing furnaces can reach a maximum temperature of 1200 ℃ or even higher, such as the RTP series rapid annealing furnace produced by Germany’s Unitan company, which has a maximum temperature of 1200 ℃.
Application: High temperature furnaces are commonly used for annealing of metal materials that require high-temperature treatment, such as stainless steel, titanium alloys, high-speed steel, and certain special materials.

2. Medium temperature furnace
Maximum temperature: The maximum temperature of a medium temperature furnace is usually within 800 ℃.
Application: Medium temperature furnaces are suitable for heat treatment of some metal materials that do not require high temperature, as well as some non-metallic materials.

3. Low temperature furnace
Maximum temperature: The maximum temperature of a low-temperature furnace is generally within 650 ℃.
Application: Low temperature furnaces are mainly used for some temperature sensitive materials, such as certain alloys, ceramics, etc., as well as occasions that require low-temperature annealing.

4. Other factors
Equipment model: The temperature range of different types of vacuum annealing furnaces may vary. For example, the RTP series rapid annealing furnace is divided into different models such as RTP-100 and RTP-150, corresponding to different sample sizes and temperature ranges.
Manufacturers: Vacuum annealing furnaces from different manufacturers may also have differences in temperature control accuracy, heating rate, cooling rate, and other aspects.
Application requirements: The specific application requirements of users will also affect the temperature range selection of vacuum annealing furnaces. For example, annealing treatment of certain special materials may require higher temperatures or more precise temperature control.

In summary, the temperature range of vacuum annealing furnaces varies due to various factors. When choosing a vacuum annealing furnace, users should choose the appropriate equipment model and manufacturer based on their specific needs, such as material type, processing temperature, sample size, etc. At the same time, attention should also be paid to the temperature control accuracy, heating rate, cooling rate and other performance indicators of the equipment to ensure the quality and efficiency of the heat treatment process.
