Heat treatment is widely used
Heat treatment is the process of artificially changing the internal structure and structure of a metal or alloy to obtain the desired performance by means of certain hot work. In the production process of various metal materials and products, in order to make the metal workpiece with the required mechanical properties, physical properties and chemical properties, in addition to the rational selection of materials and various molding processes, heat treatment is one of the indispensable important links. Heat treatment technology plays an important role and is widely used in modern process.
Heat treatment is a kind of metal thermal processing technology which controls the properties of metal materials by heating, insulating and cooling them in a certain medium and changing the metallographic structure on the surface or inside of the materials. In the whole process of metal production, corresponding heat treatment can be carried out to improve the performance of metal materials. Metal castings usually need to be annealed at low temperature to eliminate the internal stress, or complete annealing, or normalizing, some also need to be tempered after quenching (aging). The heat treatment of ingot, the heat treatment of finished products and the process of pressure processing, it is one of the main processes in the manufacture of semi-finished products and machine parts in metallurgical enterprises and machinery factories.
Metal heat treatment process can be roughly divided into three categories: integral heat treatment, surface heat treatment and chemical heat treatment. According to the different heating medium, heating temperature and cooling method, each category can be divided into several different heat treatment processes. The same kind of metal adopts different heat treatment process, can obtain different structure, thus has different performance. Iron and steel is the most widely used metal in industry, and iron and steel microstructure is the most complex, so there are many kinds of steel heat treatment process. Monolithic heat treatment is a metal heat treatment process in which the workpiece is heated as a whole and then cooled at an appropriate rate to obtain the required metallographic structure to change its overall mechanical properties. There are four basic processes of heat treatment of iron and steel: annealing, normalizing, quenching and tempering.
Heat treatment is one of the important processes in the manufacture of mechanical parts and molds. Generally speaking, it can guarantee and improve the various properties of the workpiece, such as wear resistance, corrosion resistance, etc. It can also improve the structure and stress state of the blank, so as to facilitate the cold and hot processing.
