What are the application scenarios of box type resistance annealing furnaces in the field of metal material processing?

In the field of metal material processing, box type resistance annealing furnaces have various application scenarios, mainly including the following aspects:
1. Heat treatment process
quench:
Application: Quenching is one of the important processes in metal heat treatment. By heating the metal material to a certain temperature and rapidly cooling it, the hardness, wear resistance, and fatigue resistance of the material can be improved. The box type resistance annealing furnace can provide a stable high-temperature environment to ensure the smooth progress of the quenching process.
Material: Commonly used for quenching treatment of metal materials such as carbon steel, alloy steel, and high-speed steel.
Annealing:
Application: Annealing is the process of eliminating internal stresses in metal materials during processing through heating and slow cooling, thereby improving the plasticity and toughness of the material. The box type resistance annealing furnace can accurately control the heating and cooling processes, meeting the requirements of annealing technology.
Material: Suitable for various metal materials, such as carbon steel, alloy steel, stainless steel, etc.
Normalization:
Application: Normalization is the process of heating metal materials above the critical temperature and then naturally cooling them in air, used to refine grain size, improve material structure and mechanical properties. The box type resistance annealing furnace can provide a uniform high temperature environment to ensure the normalizing effect.
Tempering:
Application: Tempering is a heat treatment process performed after quenching, which eliminates quenching stress and improves the toughness and stability of materials through heating and insulation treatment. The box type resistance annealing furnace can accurately control the tempering temperature and insulation time to ensure the tempering effect.
2. Special metal material processing
High temperature alloy treatment: For refractory metal materials such as high-temperature alloys, box type resistance annealing furnaces can provide sufficient high-temperature environment to meet their special heat treatment needs.
Hard alloy processing: Hard alloys have extremely high hardness and wear resistance, but are difficult to process. By using a box type resistance annealing furnace for heat treatment, the machinability and usability of hard alloys can be improved.
3. Research and experimentation
Materials Science Research: In scientific research and laboratory environments, box type resistance annealing furnaces are commonly used in materials science research and the development of new materials to explore the thermal properties and phase transition laws of materials. Its precise temperature control and stable heating environment provide strong support for scientific research work.
In summary, the box type resistance annealing furnace has a wide range of application scenarios in the field of metal material processing, including heat treatment processes such as quenching, annealing, normalizing, tempering, as well as the processing and scientific research experiments of special metal materials. These applications not only improve the performance and quality of metal materials, but also drive advances in materials science and technology.
