| description | PROBLEM TO BE SOLVED: To prevent a beam blank cast slab from advancing while bent, in continuous casing of the beam blank cast slab.SOLUTION: Molten steel 3 is poured into a flange part of an inside space of a casting mold 4 for casting beam blank. A beam blank cast slab 2 is formed by cooling the molten steel 3 by supplying cooling water to the casting mold 4, and the cast slab 2 is extracted while being supported by guide rolls 11, and the beam blank cast slab 2 is continuously cast. Both flange surface positions of the beam blank cast slab 2 are measured on the downstream side A in the casing direction on and after a solidification completion position 10 of the beam blank cast slab 2. A cooling water quantity is adjusted so that an extraction heat quantity becomes larger in a part of the casting mold 4 contacted with a flange surface and approaching the center line, than a part of the casting mold 4 contacted with the flange surface and separating from the center line of a continuous casting machine 1.
【課題】ビームブランク鋳片の連続鋳造において、前記鋳片が曲がって進むことを防止することである。【解決手段】ビームブランク鋳造用の鋳型４の内部空間のフランジ部に溶鋼３を注入する。鋳型４に冷却水を供給することで溶鋼３を冷却してビームブランク鋳片２を形成し、該鋳片２をガイドロール１１で支持しながら引き抜いて、ビームブランク鋳片２を連続鋳造する。ビームブランク鋳片２の凝固完了位置１０以降の鋳込み方向下流Ａで、ビームブランク鋳片２の両フランジ面位置を測定する。連続鋳造機１の中央線から離れていくフランジ面に接触していた鋳型４の部分よりも、中央線に近づいていくフランジ面に接触していた鋳型４の部分の方で、抜熱量が大きくなるように冷却水の量を調整する。【選択図】 図１ |
