冶金部钢铁研究总院自“六五”攻关（１９８３年）开始，一直坚持轧后在线控冷技术的研究和开发工作。在控制冷却装备方面先后研究开发了气一水喷雾冷却装备和水幕冷却装备。并于１９８９年获国家专利。经过近几年的深入研究又有新的突破，新研制的水幕冷却装置的特点是，水幕
Since the “6th Five-Year Plan” (1983), the Research Institute of Iron and Steel Research Institute of the Ministry of Metallurgy has always insisted on the research and development of on-line cooling control technology after rolling. In the control of cooling equipment has studied the development of gas-water spray cooling equipment and water curtain cooling equipment. And in 1989 won the national patent. After several years of in-depth research and new breakthroughs, the newly developed water curtain cooling device is characterized by water curtain
