一、前言强磁选机是近代赤铁矿选矿工业的先进技术。其导磁介质钢板又是强磁选机的关键部件。1969年开始在鞍山地区的选矿厂曾采用08F 和纯铁作介质板材料。1979年在武汉钢铁公司所辖选矿厂也采用纯铁作介质材料,均因介质板腐蚀生锈而导致选矿过程中 I. Introduction Strong magnetic separator is a modern hematite beneficiation industry’s advanced technology. The magnetically permeable medium steel plate is also a key component of strong magnetic separator. Since 1969, dressing plants in Anshan have been using 08F and pure iron as the material of the dielectric plate. In 1979, Wuhan Iron and Steel Company under the jurisdiction of concentrator also used pure iron as a dielectric material, both due to corrosion of the medium plate rust led to the beneficiation process
