Abstract
A method for producing steels by continuous casting, in which an addition material composed of an addition metal or alloy in the form of wire and a cover metal covering the addition metal or alloy is dissolved at a predetermined depth of the molten steel in a mold for continuous casting, and the cover metal prevents the addition metal from dissolving at undesired position in the molten steel, thus very advantageous for production of high grade steels and cored steels.
