Research on coating materials for CC tundish

This paper analyzes and compares the performances between magnesia and magnesia - calcia materials on refractoriness, keeping molten steel clean, insulating ability and construction.The materials are analyzed respectively based on the comparative test at Shanghai No. 1 Iron Steel Co. , Ltd. . The result shows that the magnesia material is superior to the magnesia - calcia one in performance. It is much better that the magnesia material is used for CC tundish.
