Application of Roll-EMS at Secondary Cooling Area on Angang Slab

The EMS process experiment was tested based on the orthogonal experiment table.The optimal process parameters of roll-EMS at secondary cooling area on Angang is determined by acidized inspection low power slab and drilling analysis element of segregation index.After a year of production application,it shows that the roll-EMS can improve solidification microstructure and the internal slab quality.
