摘要： A device for sensing the free surface level of melt in a continuous casting mold having an electromagnetic stirrer consisting of stirrer coils and magnetic poles therefor disposed around the circumference of the mold. The device is characterized in that at least one elongated radiation source extending in the direction of casting is arranged on one side of the mold, and that a detector for the radiation with a small extension in the casting direction is arranged on substantially the diametrically opposite side of the mold but at a height different from that of the radiation source. In the radiation path from the source to the detector an oblong slot is provided for the passage of the radiation through the pole of a stirrer coil.

摘要： A method for melting steel in an electric arc furnace (EAF). A hot heel is provided in the EAF. Metal scrap is loaded into the EAF. The metal scrap is melted in the EAF. The mass of the hot heel in relation to the mass of the metal scrap that is initially beyond the surface of the hot heel is a certain minimum. This minimum is 0.75 times the relation between the heat required to melt the metal scrap beyond the surface of the hot heel and the heat that can be taken from the hot heel without it being solidified when a theoretical heat balance calculation is applied as defined in a formula.

摘要： Method for controlling a flow of molten steel in a mould by applying at least one magnetic field to the molten steel in a continuous slab casting machine. Controlling a molten steel flow velocity on a molten steel bath surface to a predetermined molten steel flow velocity by applying a static magnetic field to impart a stabilizing and braking force to a discharge flow from an immersion nozzle when the molten steel flow velocity on the meniscus is higher than a mould powder entrainment critical flow velocity. Controlling the molten steel flow velocity on the meniscus to a range of from an inclusion adherence critical flow velocity or more to a mould powder entrainment critical flow velocity or less by applying a shifting magnetic field to increase the molten steel flow when the molten steel flow velocity on the meniscus is lower than the inclusion-adherence critical flow velocity.
