摘要 |
<p>A mold powder for continuous steel casting, containing CaO, SiO2 and fluoride as the main components. The ratio by weight of CaO', represented by the following equation, to SiO2 is 0.9-2.8 and the CaF2 content is about 5-60 wt.%. The powder contains Na2O in an amount of 0-25 wt.% and C in an amount of 0-10 wt.%. <MATH> wherein T.CaO represents the total Ca content in the mold powder as converted to CaO(wt.%) and F represents the total F content in the mold powder(wt.%). Also disclosed is a method for continuous steel casting which makes use of the mold powder. <IMAGE></p> |
