Method and device for thermal control of a continuous casting mold

An apparatus and a process for making semi-finished products in the form of ti metal bars having a width-gauge ratio of over 60 and a maximum sheet metal gauge tolerance of 2%. A metal profile is fed continuously and upwardly through a pool of melt material having the same composition as the metal profile so as to form a coated metal profile. The metal profile is fed at a rate which would result in a coated metal profile having a thickness of at least three times that of the uncoated metal profile. The coated metal profile is subjected to a smoothing pass between a pair of smoothing rolls when the mean temperature in the crystallized layer of the coated metal profile meets a given condition. The smoothing rolls are adjustably disposed inside a housing at a distance of 0.5 to 5 m from the melt pool surface.

Device for making semi-finished products

Molten steel is poured into a water cooled continuous casting mold in which the steel solidifies partially with the formation of a strand having a length and a peripheral shell. The strand has a cross-sectional surface area with one of a round shape, an oval shape and a polygonal shape having more than four sides. Additionally, the strand has a minimum circumference of 200 mm. The cross-sectional surface area of the strand leaving the mold is then reduced using rolls before the strand fully solidifies. The reducing includes deforming the strand into a polygonal shape having at least four corners while maintaining the circumference as well as the length of the strand at the peripheral shell constant.
