The development of the primary rolling mill has gone through three stages. By the early 1970s, the roll diameter of the mill has increased to 1500mm. Since 1959, China has designed and manufactured the blank opener. At present, 700mm, 750m, 850m and 1150M primary rolling mill have been made. Since 1980s, continuous casting technology has been developed greatly.

Recent years, regenerative combustion technology has been widely used in heating equipment. Compared with the heating furnace without waste heat recovery, regenerative heating furnace can save more than 40% energy. However, the investment cost is high, and there is the concept of saving energy without money saving. Recently, double regeneration (preheating gas and air 1000℃) technology is recommended for heating furnace to use surplus blast furnace gas. The efficiency is higher than 70%, and the energy saving is obvious.

The steel rolling mill machine is the main equipment for completing metal rolling deformation, and it is the key device to representing the production technology level of the workshop and different from other workshop types. Therefore, whether the selection of the steel rolling mill machine is reasonable has a very important impact on the production of the workshop.

The wire rod refers to the hot-rolled round steel with diameter of 5-22 mm or a profiled steel of considerable section. Since it is delivered in coil form, it is also commonly known as coil. Common wire product specifications are 5-13mm in diameter. According to the different rolling mills, it can be divided into high-speed wire rod and ordinary wire rod.
