CVT PULLEY SHEAVE, module 2, Teeth 12The products use a large number of heat treatment process, heat treatment refers to the metal material in solid state, through heating, heat preservation and cooling means, change the material surface or internal chemical composition and organization, to obtain the required performance of a metal hot processing process.
In the process from Stone Age to Bronze Age and Iron Age, the role of heat treatment is gradually recognized. As early as 770 BC to 222 BC, the Chinese had discovered in production practice that the properties of copper and iron would change due to the influence of temperature and pressure deformation. The softening treatment of white cast iron is an important process for manufacturing agricultural tools.
In the sixth century BC, steel weapons were gradually adopted. In order to improve the hardness of steel, quenching technology was developed rapidly. Two swords and a halberd unearthed from Yanxidu, Yixian County, Hebei Province, China, have martensite in their microstructure, indicating that they have been hardened.
With the development of quenching technology, the influence of quenching agent on quenching quality is gradually discovered. Pu Yuan, a man of Shu of The Three Kingdoms, once made 3,000 dao for Zhuge Liang in the xigu valley of today's Shaanxi Province. According to legend, he sent his people to Chengdu to get water for quenching. This shows that in ancient times China paid attention to the cooling capacity of different water qualities, as well as the cooling capacity of oil and urine. A sword unearthed in China from the tomb of King Jingwang of Zhongshan in the Western Han Dynasty (206 BC ~ AD 24) contains 0.15-0.4% carbon in the heart, but more than 0.6% carbon in the surface, indicating that carburizing process has been applied. Therefore, the quenching process in China has a source of support.
