为推广稀土在钢中的应用,稳定稀土在钢中的作用.稀土向钢中加入芳法的问题一直是稀土应用领域探讨和研究的重要课题.1979年包头全国稀土会议和同年冶金部稀土钢和稀土加入方法会议都重点安排了这项研究任务.据此精神山东省冶金研究所和山东冶金机械厂合作拟定了“钢包机械法加稀土工艺及其装备”的研究方案,经过两年的试验,改进和完善了工艺,同时研制成功一台结构简单、功能全面、操作方便的包内加稀土专用设备,1981年12月14日由山东省科委组织有关单位召开了技术
In order to promote the application of rare earth in steel and stabilize the role of rare earth in steel, the problem of adding rare earth to steel by adding rare earth has always been an important issue for the research and application of rare earths.The Baotou National Rare Earth Conference in 1979 and the rare earth steel And rare earth join the meeting of the method are focused on the task of arranging the mission.According to the spirit of Shandong Institute of Metallurgy and Shandong Metallurgical Machinery Factory to develop a “ladle mechanical method plus rare earth technology and equipment” research program, after two years Test, improve and improve the process, while the successful development of a simple structure, full-featured, easy to operate package rare earth plus special equipment, December 14, 1981 by the Shandong Provincial Science and Technology Commission organized the relevant units held a technology
