Improvement in Mold Powder for Prevention of Deckel Phenomina in Continuous Stainless Bloom Continuous Casting Process

摘要

invention bulrum stainless steel (Stainless Bloom) during the use of continuous casting mold powder and sintered powder layer or more of the coagulation phenomenon relates to the improvement of the mold powder layer for preventing effect so , CaO, SiO ₂ , Al ₂ O ₃ , CaF ₂ Fe _{on the basic components of the 2} O ₃ , Al ₂ O ₃ , Na ₂ O, MgO , etc. , and the addition of a very small amount , and to have a composition by weight percent of 4.21% of free carbon and 5.03% CO ₂ , the basicity 1.03 , a viscosity of at least provide a stainless steel double anti- clotting during continuous casting mold powder wherein configured so that 5.62Poise.
