【Abstract】 With inert gases or mechanical agitation, the new refining and grain refinement composite material formed of fly ash micro-sphere used for steel is put in fused liquid steel and react immediately with it in several minutes,then sampling,casting and detecting.The effect of decarburization refining is well,and the gradation of grain refinement is increased.The decarburization refining and grain refinement of steel are realized on the product line synchronously.更多还原
