Background technique

Metallurgy is the process and process of extracting metals or metal compounds from ores, and using various processing methods to make metals into metal materials with certain properties. Metallurgy has a long history of development in our country, from the Stone Age to the subsequent Bronze Age, and then to the large-scale development of modern iron and steel smelting. The history of human development incorporates the development of metallurgy. Metallurgy, developed from ancient pottery. The first is copper smelting. The melting point of copper is relatively low. With the development of pottery, the working temperature required by pottery is getting higher and higher, reaching the melting point of copper. In the process of making pottery, in some places where there are copper mines to make pottery, copper is naturally found as epiphyte. With the accumulation of experience, the ancients gradually mastered the copper smelting method. Metallurgical technologies mainly include pyrometallurgy, hydrometallurgy and electrometallurgy. With the successful application of physical chemistry in metallurgy, metallurgy has moved from technology to science. Iron powder is the main raw material for powder metallurgy. Powder metallurgy technology has been widely used in transportation, machinery, electronics, aerospace, weapons, biology, new energy, information and nuclear industries, and has become one of the most dynamic branches of new material science.
