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.

Full continuous, no twist, high speed rolling. The roughing rolling mill and intermediate rolling mill are alternately arranged, and the pre-finishing rolling mill is installed in front of finishing mill. The maximum finishing rolling speed is 120m/s. The latest rolling speed guaranteed by the production practice will be proposed according to the different specifications of the wire rod, such as Siemens in 2010. The company has designed and manufactured high-speed wire rod mills for Xuanhua Iron and Steel Co., Ltd., and its final rolling speed guarantee value: small 5.5-7.5mm, wire rod 112m/s, medium φ5mm wire rod l 105m/s, The small φ6mm hardened rebar is 85m/s.

The wire rod mill is a rolling mill dedicated to rolling wire rods. The wire rod is the product with the smallest cross-section in profile steel. Rolling from a billet into the finished product, the total elongation coefficient is large. The rolling stock is often rolled only once on each rolling mill machine. Therefore, the wire rolling mill has the largest number of racks and the finest division of labor in the hot-rolled profiles.
