绪言压力加镁这种球化处理方法问世已很长时间了。在我国除了一些生产大型球墨铸铁轧辊的单位采用外,还没有得到普遍的应用。这里介绍的“重力式压力加镁设备”是笔者1967年在邢台冶金机械修造厂设计的。1970年又在乐山冶金机械轧辊厂与有关同志一起,对压力加镁理论作了进一步探讨,对设备结构进行改进后设计出的新型设备。现在这种设备不仅在上述两个厂一直使用,而且先后推广到北京轧辊厂、太钢轧辊厂、沈阳轧辊广、鞍钢轧 Introduction Pressure plus magnesium This ball treatment has come out for a long time. In our country, except for some units that produce large nodular cast iron roll, it has not been widely used. Here introduced the “gravity pressure plus magnesium equipment” is the author in 1967 in Xingtai metallurgical machinery factory design. In 1970, Leshan Metallurgical Machinery Rolling Mill together with the relevant comrades made a further discussion on the theory of pressure plus magnesium, and designed a new type of equipment after the equipment structure was improved. Now this equipment not only in the two plants has been using, and has been extended to Beijing Roll Factory, TISCO Roll Factory, Shenyang Roll Wide, Ansteel rolling
