This invention relates to a suitable material cutting and slag removal device that can simultaneously remove the solvent from the slag adhering to the slag.

``Conventional technology'' Conventionally, on the rolling line, % of the material was removed? The steel material is cut to length to be rolled, and the slag generated at the lower end of the steel material during cutting is removed, but the cutting of the steel material and the removal of the slag are each performed using separate devices. Also, the only way to remove slag is with a separate device for each piece of steel after cutting.

``Problems to be Solved by the Invention'' Conventionally, it has been possible to continuously cut steel materials on a rolling line and subsequently remove slag, improving efficiency. Since the cutting and slag removal are performed using separate devices, the location where the steel material cutting operation is performed and the location where the slag removal work is performed must be separated to some extent.
