What is the function of induction heating and quenching equipment?

The so-called quenching is a metal heat treatment process in which the metal workpiece is heated to a suitable temperature and kept for a period of time, and then immersed in the quenching medium for rapid cooling. Common quenching media in the daily production process include brine, water, mineral oil, air, etc. The quenching process can improve the hardness and wear resistance of metal workpieces to a certain extent, so it is widely used in various tools, molds, measuring tools and other parts that require surface wear resistance (such as gears, rolls, carburized parts, etc.). Through the combination of quenching and tempering at different temperatures, the strength, toughness and fatigue strength of metal workpieces can be greatly improved, and the coordination between these properties (comprehensive mechanical properties) can be obtained to meet different use requirements. In addition, quenching can also make some Steel with special properties has certain physical and chemical properties, such as quenching to enhance the ferromagnetism of permanent magnet steel, and stainless steel to improve its corrosion resistance.

Cooling methods and quenching processes are divided into four types: single liquid quenching, double medium quenching, martensite graded quenching and bainite isothermal quenching. Therefore, when choosing a quenching method, it is also necessary to choose according to the comparison.
