Abstract: The industrial scale tests of the electromagnetic casting rolling technology were described. The effects of electromagnetic field on the casting rolling strip breakdowns were studied by analysing their microstructures and mechanical properties. The results show that the electromagnetic casting rolling can effectively refine the grain size to ASTM grain size number grade 1, eliminate horseshoe cracks, improve dendritic segregation, and suppress the gas passages defects caused by the hanging slags on the casting nozzles. Using electromagnetic field to replace the Al-Ti-B wire modificator can not only reduce the earing ratio of the casting rolling strip and improve the deep drawing property, but also reduce the production cost by 60～70 RMB Yuan/t.
