摘要： A method and apparatus for continuous steel casting in which a tubular copper ingot mould is fed with molten steel through an intermediate, so-called ''''tundish'''' pool filled in turn by means of a steelwork ladle. The molten steel, during its passage from the intermediate pool to the ingot mould, is isolated from the surrounding atmosphere by means of a dipper pipe made of sintered vitreous silica. the lubrication between the copper walls of said ingot mould and the steel undergoing a solidification therein is provided by a synthetic slag excluding any organic oil, the slag, which covers the steel surface in the ingot mould being selected from the group of substances having such viscosity and wetting capacity with respect to copper and steel that they can on the one hand penetrate by capillarity action between the copper of the ingot mould and the steel being solidified therein, and on the other hand be carried along in the form of an extremely thin layer between said copper and steel. An additive selected from the group comprising tellurium, selenium, a mixture of these two elements and a chemical combination of one of these two elements is added either into the steelwork ladle, during the filling thereof from a steelwork furnace and before the steel therein is poured into the intermediate pool, or into the intermediate pool, the addition taking place progressively and continuously throughout the casting operation.
