Description

Intermediate frequency quenching device for roller

Technical Field

The utility model relates to the technical field of roller generating equipment, in particular to a medium-frequency quenching device for a roller.

Background

The prior quenching technology is a metal heat treatment process which heats a metal workpiece to a certain proper temperature and keeps the temperature for a period of time, and then the metal workpiece is immersed into a quenching medium for rapid cooling. Common quenching media are brine, water, mineral oil, air, and the like. The quenching can improve the hardness and the wear resistance of the metal workpiece, so the quenching steel is widely used for various tools, dies, measuring tools and parts requiring surface wear resistance, such as gears, rollers, carburized parts and the like. Through the matching of quenching and tempering at different temperatures, the strength, toughness and fatigue strength of the metal can be greatly improved, and the matching (comprehensive mechanical properties) among the properties can be obtained to meet different use requirements. In addition, quenching can also make some special steel obtain certain physical and chemical properties, for example, quenching can make permanent magnet steel strengthen its ferromagnetism, stainless steel raise its corrosion resistance, etc. The quenching process is mainly used for steel parts. When the conventional steel is heated to a temperature higher than the critical temperature, the original structure at room temperature is completely or mostly transformed into austenite. The steel is then rapidly cooled by immersion in water or oil, and the austenite transforms to martensite. The martensite hardness is highest compared to other structures in steel. The purpose of quenching steel is to transform all or most of the structure of the steel into martensite, obtain high hardness and then temper the steel at a proper temperature so as to enable the workpiece to have expected performance, and the prior intermediate frequency quenching device for the roller is troublesome and inconvenient to use, thereby influencing the efficiency of quenching production of the roller.
