摘要
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.
