The State launched the "12th Five-Year Plan" for the development of intelligent equipment for the comprehensive mining of coal
Continuous casting slabs or primary rolling slabs are used as raw materials, heated by a stepping furnace, and dephosphorized by high-pressure water, and then enter the roughing mill. The rough rolling material is cut through the head, tail, and then into the finishing mill, and computer-controlled rolling is carried out. After the final rolling, it will go through laminar cooling (computer-controlled cooling rate) and take-up by the coiler to become a straight hair coil. The head and tail of straight hair curls tend to be tongue-shaped and fish-tailed, with poor thickness and width accuracy, and often have wavy, folded, tower-shaped and other defects on the edges. The coil is heavier and the inner diameter of the steel coil is 760mm. (Generally used in the pipe-making industry.) After straightening the hair through the cutting head, tail cutting, trimming and multi-pass straightening and smoothing finishing lines, and then cutting or re-rolling, it becomes: hot rolling steel plates, flat hot rolled steel coils, slitting tapes and other products. If the hot-rolled finishing coil is pickled to remove scale and coated with oil, it will become a hot-rolled pickled coil.

It is understood that this project is the country's largest fund subsidy project in the 12th Five-Year Plan for smart equipment development special projects. Taizhong Heavy Machinery Co., Ltd. and Xishan Coal & Electricity Co., Ltd. are cooperating with Pingyang Heavy Industry, Shanxi Keda, Luo Kejiahua and Taiyuan University of Technology. And other units jointly completed the research of 15 key core intelligent devices and the production of wells and underground mining equipment, and built an intelligent 10 million-ton safety and high efficiency demonstration work surface at Xishan Coal & Electricity Group.
