A method for reducing target surface features in continuously cast articles is described. The method can remove a target surface feature, such as a compositional variation or casting defect, from the continuously cast article by removing, before cold rolling, material from the continuously cast article surface.

A device for achieving a core part press-down technology in a continuous casting round billet solidification process includes a plurality of round billet radial press-down devices distributed along an axial array of round billets outside a press-down interval of the round billets. The press-down interval is an area from 0.65 of a solid phase ratio of the round billets to solidification end points. Each round billet radial press-down device includes a plurality of press-down rollers. A forming hole for extruding the round billets is formed between the press-down rollers. Two adjacent round billet radial press-down devices are arranged in the manner of staggering. The device can effectively solve the defect problems of porosity, segregation and the like in the core of the continuous casting round billets, the yield of the continuous casting round billets is increased, and the production cost is reduced.

A continuous casting and rolling line for casting, rolling, and otherwise preparing metal strip can produce distributable metal strip without requiring cold rolling or the use of a solution heat treatment line. A metal strip can be continuously cast from a continuous casting device and coiled into a metal coil, optionally after being subjected to post-casting quenching. This intermediate coil can be stored until ready for hot rolling. The as-cast metal strip can undergo reheating prior to hot rolling, either during coil storage or immediately prior to hot rolling. The heated metal strip can be cooled to a rolling temperature and hot rolled through one or more roll stands. The rolled metal strip can optionally be reheated and quenched prior to coiling for delivery. This final coiled metal strip can be of the desired gauge and have the desired physical characteristics for distribution to a manufacturing facility.
