120mm×120mm连铸坯一火成材改造工艺设计及实践

Technical Design and Its Practice of "Roll in One Heat" Reformation of 120mm×120mm Continuous Casting Billet

横列式轧机实现连铸坯一火成材是降低消耗增加效益的有效途径，而改造成功的关键是确保轧制温度和匹配粗、精轧的轧制节奏，本文从工艺设计方面介绍了解决这两个问题的措施并在实践中完善，取得了很好的效果，经济效益显著。

To achieve 'roll in one heat' of continuous casting billet produced by open--train mill is a effective measure for decreasing the energy consumption and the hay of reforming sucess is to ensure the reasonable rolling temperature and the matching between rough rolling and finishing rolling system. This paper introduces some measures for solving above mentioned qenstions from the way of technical design.
