摘要/Abstract

摘要： 综述了钢中夹杂物的尺寸、种类、数量和形态对无取向硅钢磁性能的影响。无取向硅钢中的夹杂物,以尺寸较小的MnS、AlN、Cux S等为主。对磁性能影响较大的夹杂物尺寸为0.1～1.0μm,随钢中夹杂物数量增加,对硅钢磁性能劣化的影响增大。采用钙、稀土处理,可以去除无取向硅钢中绝大部分的微细夹杂物,并形成尺寸较大的稀土、钙氧硫化物。工业化生产过程中,应优先改善夹杂物的尺寸,尽量避免生成0.1～1.0μm尺寸范围内的夹杂物。同时,根据冶金设备、精炼方法、连铸工艺,选择夹杂物控制高纯化,还是无害化生产路线。

Abstract: The effects of size, type, amount and morphology of inclusions in steel on magnetic properties of non-orien- ted silicon steel is reviewed. The main kinds of inclusions in non-oriented silicon steel are smaller size MnS, AIN, and CuxS etc. The inclusions of dimension 0. 1 ~ 1. 0μm have larger influence on magnetic properties of steel and with increasing the number of inclusions in steel, their negative influence on magnetic properties of silicon steel increases. Almost all of the minor inclusions in non-oriented silicon steel could be removed by calcium and RE treatment to form larger size RE and calcium oxysulphide inclusions. In commercial production a first priority is to improve the size of inclusions, avoid formation of the inclusions with size range of 0. 1 ~ 1. 0μm and based on metallurgy equipment, refining method and casting process to select high purity or harmless process flow sheet for controlling the inclusions in steel.
