摘要
PURPOSE: A method for smoothening a mold is provided to improve the surface quality of a cast piece and a cast speed, to prevent re-oxidization of molten steel, to heat the molten steel and to collect a slag. CONSTITUTION: Smoothness is secured between a solidifying cell(4) formed in a water cooling cast piece(3) and the waster cooling cast piece. Mold powder(16) is used on a molten steel face to collect and heat an inclusion and to prevent re-oxidization in a fire resisting mold(2). A wick(12) is installed between the mold(2) and the water cooling cast piece(3) by using a thread having 0.1 to 2mm thickness to give a condition of inputting oil in an initial solidifying part. The lubricating oil is input in a rear wick layer(13) of the wick(12), and the wick smoothens between the mold and solidifying cell by absorbing the lubricating oil.
