The application of box type vacuum atmosphere muffle furnace in the powder metallurgy industry is extensive and critical, mainly reflected in the following aspects:
1. Metal powder sintering: In powder metallurgy technology, a box type vacuum atmosphere muffle furnace is used for sintering metal powder to prepare various metal and alloy components, such as gears, bearings, metal filters, etc. By accurately controlling the temperature, atmosphere, and holding time inside the furnace, the densification of metal powder can be achieved, improving the density and mechanical properties of sintered parts. For example, during the sintering process, a nitrogen atmosphere is commonly used to avoid oxidation reactions, which is suitable for sintering nitrides and certain metal materials; Hydrogen atmosphere is commonly used for the reduction sintering of metal materials, which helps to remove the oxide layer on the surface of metal powder and promote the densification of the metal.
2. Hard alloy sintering: Hard alloys (such as tungsten steel) have high hardness and wear resistance, and are important materials in cutting tools, molds, mining tools, and other fields. The box type vacuum atmosphere muffle furnace plays an important role in the sintering process of hard alloys. Accurately controlling the atmosphere inside the furnace through an atmosphere control system can prevent oxidation reactions of hard alloys at high temperatures, ensuring the quality and performance of sintered parts. Meanwhile, by adjusting the sintering temperature, holding time, and atmosphere composition, the microstructure and mechanical properties of hard alloys can be optimized to meet the needs of different application fields.
3. Powder metallurgy reduction treatment: The box type vacuum atmosphere muffle furnace is also suitable for reduction treatment in powder metallurgy. In a reducing atmosphere, metal powders can be reduced and sintered to remove oxide impurities and improve the purity and properties of the metal. This is of great significance for the preparation of high-performance metal materials and alloys.
4. New material research and testing: In the process of powder metallurgy new material research and development, the box type vacuum atmosphere muffle furnace can be used to synthesize new materials, study the phase transition process of materials, and evaluate the properties of materials. By controlling the atmosphere and temperature, the preparation methods and properties of new materials can be explored, providing basic data and technical support for the development of new materials.
