The present application discloses a convex lens-shaped narrow face copper plate for continuous casting molds and its utilization method. The narrow face copper plate includes a first hot face and a second hot face. A first connecting line being provided at a joint of the first hot face and the second hot face, and two such first connecting lines being provided. A cross section of the first hot face is a convex arc, and the first hot face extends from an top of the narrow face copper plate to a bottom of the narrow face copper plate, and a height of the first hot face protruding relative to a plane where the two first connecting lines are located gradually decreases from the top of the narrow face copper plate to the bottom of the narrow face copper plate.

A die (for a continuous casting installation) that includes a movably mounted frame having a first subframe and a second subframe; a first broad-side insert which is positioned on the first subframe; and a second broad-side insert which is positioned on the second subframe. Narrow sides each having a narrow-side copper plate and abuting the two broad-side inserts are positioned between the two broad-side inserts. The die also has: a clamping device which is designed to exert, on the subframes, a clamping force that acts between the subframes; and an oscillation drive which is designed to make the frame oscillate in and counter to a horizontal width direction (H) relative to the narrow sides. A spring band assembly which guides the subframes is positioned on each subframe on sides which are opposite one another in the width direction (H).

An apparatus and a system including a casting pit; a mold including a reservoir and a cavity; a coolant feed operable to introduce a coolant to a periphery of a metal emerging from the mold cavity; an array of water vapor exhaust ports about at least the top periphery of the casting pit; a mechanism to introduce an inert fluid into the coolant feed. A method for a direct chill casting including, after detecting a bleed out, exhausting generated gas from the casting pit at a flow volume rate that is enhanced relative to a flow volume rate prior to detecting bleed out or run out; introducing an inert gas into the casting pit; and introducing an inert fluid into a coolant feed to the casting mold.

The invention provides rotating a submerged nozzle during casting to arbitrarily change the discharge angle of molten metal, causing the molten metal in the mold for slab to be rotated and stirred. A slab continuous casting apparatus according to the invention supplies molten metal from a tundish to a water-cooled mold for slab through at least an upper nozzle, a slide valve and a submerged nozzle and solidified the molten metal and provided with a submerged-nozzle quick replacement mechanism. The slab continuous casting apparatus further includes a discharge-direction changing mechanism capable of arbitrarily changing discharge angle of the molten metal as viewed in a horizontal cross section, during casting, the discharge-direction changing mechanism being provided between a slide valve device for opening and closing the slide valve and the submerged nozzle.
