铝铸轧板坯产生严重裂边的主要原因是,铸轧区偏高、供料嘴结构不合理和铸轧辊质量不佳.经过改进工艺并采取相应的控制质量的措施,使铸轧板坯裂边减小,其边部质量超过了国外同类型铸轧机生产的板坯边部质量水平,提高了生产率和成品率“,”The edge cracks of aluminum continuous cast-rolled strips result from that the cast-rolling zone is a little higher,the structure of tips is not reasonable,and the quality of cast-rolling roller is not good.Through improving the cast-rolling technology and adopting control measures.the edge cracks of the aluminum continuous cast-rolled strips are obviously decreased.The quality of aluminum cast-rolled strips produced by our continuous has exceeded quality of those strips produced by the same type foreign co...
