Casting spout for metallurgical vessels

A method for continuous casting metal products under utilization of a mold and pouring molten metal into the mold to obtain a flat stock with a thickness below 100 mm, includes withdrawing the partially solidified casting by at least one roll pair which reduce the thickness of the stock upstream from complete solidification by at least 10% but not more than 70% while further reduction in thickness by at least 30% obtains downstream from complete solidification is improved by requiring that the product being cast has a thickness not below 50 mm; that exclusively internally cooled rollers are used for obtaining the reduction; and that the thickness is reduced downstream from the complete solidification at a point where the temperature is only little below the solidus temperature particularly in the case of steel being a temperature between 1500 and 1200 degrees C.

Combined continuous casting and rolling

Seen against the direction of casting, the narrow width dimension of a mold is widened through appropriate surface contour, at least in the mold center, to facilitate charging of the mold whereby the lower portions of the longitudinal walls of the mold are essentially parallely curved while in the upper portion at least one of the walls tangentially merges into the pour-in portion of the mold.
