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.

The technology of direct rolling without heating of bar and wire refers to the technology of directly sending the slab with residual heat after continuous casting into the rolling mill line for rolling. When the heating-free process is used, the billet does not need to be heated in the furnace, and it does not need to be reheated (some of which replenishes the corner parts through the electromagnetic induction device), completely eliminating the fuel consumption of the heating furnace, which can greatly save energy and reduce carbon dioxide of emissions.

The low temperature direct rolling technology without heating and compensation is applied to the production line of high strength and anti-seismic steel bars. The typical processes include four-machine four-strand continuous casting machine, out-of-billet roller table, transverse adjusting device and rolling line.
