Abstract
Mold apparatus for continuous casting of metal, has an intermediate plate for supplying one or more mold release agents to the surface of the billet or ingot forming in a cooled mold. The intermediate plate has outlet openings which terminate in an intermediate area between a hot top section and a mold section in which the molten metal solidifies. The intermediate release agent supply plate having a central cross sectional opening is provided between the hot top section and the mold section, the surface of the central opening, adjoining the surfaces of the hot top section and the mold section. The intermediate plate comprises a flat plate having release agent-supply channels that extend to the opening edge and are precision-formed into the upper and lower surfaces of the intermediate plate to a constant depth. Liquid and/or gaseous mold release agents are fed through the supply plate to lubricate the mold surface along which the ingot is formed, cooled and lowered.
