摘    要：ASP生产线是一种新型短流程热轧带钢生产线,其独特的生产组织方式和品种结构对精轧机组的板形控制能力要求较高,一套常规轧辊辊型很难同时兼顾所有品种带钢的板形。在2150ASP生产线,通过采用LVC工作辊辊型技术,ASPB支持辊辊型技术,制定合理的板形控制策略,配置切实可行的带钢板形自动控制系统等一系列手段,大大提高了精轧机组的板形控制能力,一套辊型可适应所有品种对板形的要求,并且在保证带钢板形控制能力的前提下,换辊周期明显延长,工作辊换辊周期达到了70~100 km,支持辊换辊周期达到了20万~40万t,不仅提高了生产效率,同时也为2150ASP生产线实现自由程序轧制奠定了坚实的基础。

Abstract: ASP is a new type of hot strip production line,adapting special production management and products variety,it is necessary that there is high adjusting capacity for flatness and profile in finishing mill.It is difficult for a set conventional roll contour to meet all the varieties of strip shape.In 2150ASP production line,after using LVC technique,ASPB technique,establishing-shape control strategy,configuring a feasible shape automatic control system,the capacity of shape control in finishing mill was increased greatly,and whatever the variety was produced,using a set LVC work roll contour can meet the requirements of shape.Roll service time was increased evidently,service time of work roll can reached 70-100km,and service time of back-up roll can reach 200-400 thousand tons.Not only the production efficiency has been improved,but also has laid a solid foundation for achieving free schedule rolling in 2150ASP.
