本科研项目是国家科委和冶金部下达的重点科研课题“控制轧制”项目之一。三年来,先后进行了多次实验室和工业性试验,改善了冶金质量,开展了机理研究工作,确定了适合现场实际情况的合理控制轧制工艺,增设了必需的监测装置,建立了原始数据记录及处理系统。从1979至1981年采用控制轧制工艺共生产了厚度35毫米以下的4(?)(D级)造船钢板5万余吨。大连造船厂、江南造船厂和上海造船厂,使用这种钢板先后制
This research project is one of the key scientific research projects “Control Rolling” issued by the State Science and Technology Commission and the Ministry of Metallurgy. Over the past three years, we have carried out many laboratory and industrial experiments to improve the metallurgical quality, carried out the mechanism research work, determined the reasonable control rolling process suitable for the actual situation in the field, added the necessary monitoring devices and established the raw data Recording and processing system. From 1979 to 1981, a total of more than 50,000 tons of 4 (?) (Class D) shipbuilding steel sheets with a thickness of 35 mm or less were produced by controlled rolling. Dalian Shipyard, Jiangnan Shipyard and Shanghai Shipyard, the use of such a plate system
