The main content of << Tian Gong Kai Wu >> about iron-making was to describe the technical route and process of iron-making in ancient times. In ancient times, iron-making techniques were divided into two categories: one was block iron-making, which was relatively primitive, and the other was pig iron-making, which was relatively mature. Due to the limited temperature of the furnace, the early artificial iron smelting could only produce iron blocks with more impurities. After repeated forging, it could become wrought iron, and then through heating, forging, cementation, and other processes, it could be made into steel. Later on, the pig iron smelting technology appeared, and the quality of the products improved greatly, allowing them to be widely promoted. At the same time, with the help of the " steel frying method ", iron ore powder was added to the heated semi-liquid pig iron, and the contact area with the air was constantly stirred to reduce the carbon content and various harmful impurities in the pig iron. After repeated forging, it was finally made into a steel product with better performance. If you want to know more about the follow-up, click on the link and read it!
