In top pouring an ingot using cover flux, a cylindrical, i.e. tubular float is placed within the ingot-making mold. Molten steel is poured into the float while, at the same time, cover flux is continuously supplied to the area between the float and the mold walls. With continued pouring of molten steel, the float moves up and the flux covers the surface of the molten steel. After casting, the float is easily broken down when the ingot is stripped of the mold. The float is made of a light material which is resistant to heat and is easily breakable. |
