Metalworking technology

Metalworking refers to the production activity that human beings process materials with metal properties that are mainly composed of metal elements or metal elements.The progress of human society and the relationship of metal material processing and application is very close, in the smelting of brass, more than six thousand years ago in more than four thousand years ago can be made simple bronze tools made of corrugated iron weapon, the start of the three thousand years ago in China two thousand five hundred years ago in the spring and autumn period has smelting iron, is more than one thousand eight hundred years earlier than in Europe.In the 18th century, the development of iron and steel industry became the important content and material basis of the industrial revolution.From one million years ago, primitive people used stones as tools, called the Paleolithic Age.Ten thousand years ago, man made stone tools into utensils and delicate tools, thus entering the Neolithic Age.Archaeological excavations have proved that China has made practical pottery more than 8,000 years ago, smelted brass more than 6,000 years ago, made simple bronze tools more than 4,000 years ago, and made weapons with meteorite more than 3,000 years ago.Our ancestors smelted pig iron more than 2,500 years ago in the Spring and Autumn Period, more than 1,800 years earlier than the Europeans.In the 18th century, the development of iron and steel industry became the important content and material basis of the industrial revolution.In the middle of the 19th century, the emergence of modern open-hearth furnace and converter nickel-tube steelmaking technology enabled human beings to truly enter the steel age.At the same time, copper, lead, zinc are also widely used, aluminum, magnesium, titanium and other metals have been produced and used.Metal materials have always occupied a dominant position in the material industry.Metal materials can be said to be a witness of the whole process of the development of human society. The reason why it is said so is that it plays a pivotal role in each transition period of human society.As one of the first materials discovered and used by human beings, metal has influenced the historical development of human beings from all aspects.From the beginning when metal was turned into hunting weapons to the present day, human life has been completely inseparable from metal. It can be seen that metal has long been integrated into the whole human society. So what will be the past and future of metal in human society?
