研究钢锭端部变形,对提高成坯率,节约轧制过程的金属消耗有重要意义,并能改善钢坯质量。本文主要模拟初轧条件,对鱼尾产生和发展的规律,以及轧制因素对鱼尾的影响进行探讨。并对沸腾钢锭大、小头进钢进行对比,在不同轧制条件下,模拟试验及生产试验均证实大头进钢可以减少鱼尾量0.6～2.6％。 Research ingot deformation of the ingot, to improve the billet rate, saving the rolling process of metal consumption is important, and can improve the quality of billets. This paper mainly simulates the conditions of initial rolling, the law of emergence and development of fishtail, and the influence of rolling factors on fishtail. The comparison of the big ingot and the small ingot into the steel in the ingot ingot showed that the bulk tapping steel can reduce the fish tail volume by 0.6-2.6% under different rolling conditions.
