【Abstract】 The grade and distribution of inclusion in (800～1200)mm×180 mm concasting slab produced by extra-low head concaster have been analyzed. The inclusions in slab mainly consist of complex inclusions and MnS, and the amount of inclusion obviously increases at inside of slab due to the small curve-shaped radius of extra-low head concaster.更多还原
