工业化研制薄板坯连铸连轧取向电工钢的组织和性能

Microstructure and properties of grain oriented electrical steel produced commercially by compact strip processing on production lines

摘要: 采用薄板坯连铸连轧工业生产设备及常规取向硅钢生产技术开发了低成本取向硅钢生产技术,成品性能达到国家牌号标准30Q150.通过适当的热轧板退火处理可获得粗大的热轧板晶粒组织,这有利于促进抑制剂数量的增加及Goss织构的增强,使钢板磁性能提高到30Q140标准.

Abstract: A commercial production line of compact strip processing and a production technology for conventional grain oriented electrical steel were used to manufacture low cost grain oriented electrical steel, whose magnetic properties reached the level of 30Q150. Proper hot band annealing was introduced in order to obtain coarse grain size which promoted the strengthening of Goss texture as well as the increasing of inhibitors' number, so that the magnetic properties could reach the level of 30Q140.
