The earliest steel forming methods are far from being as advanced as they are now. They were obtained by manual forging. Until the first industrial revolution saw the emergence of machines, manual forging was replaced by machine forging. With the invention of the steam engine and the application of steam as power, with the emergence of industrial steam hammers, the development of electrical technology and the application of electric motor drives have promoted the development of mechanical presses, and then hydraulic components and hydraulic technology have appeared. Technical means are well applied in the field of section steel forging.
In the past half century, China's die forging equipment and forging technology have developed rapidly, mainly due to scientific developments such as computer technology and manufacturing technology. This not only makes the performance of the equipment further improved, but also plays a huge role for the entire cold drawn steel industry. Although compared with industrially developed countries, there is still a certain gap in the technology and level of equipment in this field in China, which needs to be further improved.
