| Abstract: | A newly developed micro-particulate-like bi-functional steel refining agent which is separated from coal ash, is put in molten steel to simultaneously bring about steel refining and grain refinement. With inert gas or mechanical agitation, the agent reacts quickly with the molten steel, with the reaction completed in a few minutes. Sampling, casting and examination are then done to evaluate the agent. It was found that the decarburization-refining effect was good, and a satisfactory grain refinement was attained, thus realizing both decarburization-refining and grain refinement in a single process with a single refining agent. |
