摘要： A method and system for processing molten slag is characterized in that molten slag is first spread onto a slag receiving means which is substantially made of a steel plate of desired thickness and is tiltably mounted on the floor of a roofed slag processing factory and is subsequently air and water-cooled such that the slag is solidified and finally is water-quenched in a cooling water pit whereby the resulting solidified slag is of practical use which neither collapses nor produces dust.

摘要： A method for producing a killed molten steel for continuous casting, which comprises;A step of preparing a molten steel with a blow-off carbon content not less than 0.05% in a converter,A step of pouring the molten steel to a ladle, andA step of degassing the molten steel in vacuum degassing vessel under a vacuum within a range of from 10 to 300 mmHg, with addition of at least one element selected from the group consisting of Al, Si and Mn, while stepwisely adjusting the vacuum in correspondence to the degree of decarburization of the molten steel.
