A method and apparatus of processing a continuously cast slab to prevent the formation of surface cracks by applying plastic strains to the surface layer of the slab in which a process of solidification is taking place. The method comprises pressing a projection against the slab surface under specified conditions prior to introducing the slab to a leveling stage.

Method of processing continuously cast slabs

A plurality of sets of three rolls are disposed around the periphery of the round continuously drawn from a mold and movable to the direction for or counter to the rounds, the sets being disposed along the drawing direction of the rounds. It is not necessary to replace the apparatus even when the size of the round is changed due to the replacement of molds, as the roll position are adjustable to the rounds.

Supporting and guiding apparatus continuous rounds casting

A mold of copper or copper alloy for continuously casting steel comprises a rough inner surface, a plating of nickel, cobalt or alloy thereof formed over the inner surface and a chromium plating formed over said plating. The mold has a prolonged mold life, gives steel slabs with improved qualities and reduces amounts of lubricating material used in the molding operation.

Molds for continuously casting steel

A copper or copper alloy mold for continuously casting steel is characterized in that the mold has a first layer formed on its interior surface and comprising at least one of nickel and cobalt and a second layer formed on the first layer and containing at least one of nickel and cobalt as a main component and at least one of phosphorus and boron.

A measuring means for measuring secondary cooling zone roller gaps in continuous casting machine, wherein measuring means having detecting means for detecting the position of ingot support means are provided on dummy bars transferred through the secondary cooling zone, the ingot support roller gap being measured by the output signal of said detecting means. Each said detecting means is slidable, and output corresponding to its displacement range is measured and recorded.
