Quenching lifting device

Technical Field

The utility model relates to the technical field of quenching, in particular to a quenching lifting device.

Background

The quenching of steel is a heat treatment process of heating the steel to a temperature above a critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), preserving the heat for a period of time to make the steel fully or partially austenitized, and then rapidly cooling the steel to a temperature below Ms (or isothermal near Ms) at a cooling speed greater than a critical cooling speed to perform martensite (or bainite) transformation. The solution treatment or heat treatment with rapid cooling of materials such as aluminum alloys, copper alloys, titanium alloys, tempered glass, etc. is also commonly referred to as quenching, and the heat treatment of metals is a process in which a metal workpiece is heated to a suitable temperature and held for a period of time, and then immersed in 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 method is widely used for various tools, dies, measuring tools and parts (such as gears, rollers, carburized parts and the like) with the required surface wear resistance. Through the matching of quenching and tempering at different temperatures, the strength, toughness reduction 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.
