采用辊切轧制提高轧机吃坯能力

ROLLING BIGGER BILLETS WITH THE METHOD OF SLIT ROLLING

为了解决小轧机如何使用大连铸坯的问题，本文提出用辊切轧制的方法。并从轧件受力和不均匀变形两方面分析了辊切变形的机理；讨论了辊切轧制的孔型设计方法、配辊方法和导卫设计方法，分析了采用辊切轧制方法后可能带来的经济效益。

In order to roll bigger continuous casting billcts using small section steel mill and improve it's capacity, the method of roller slit rolling is put forward in this paper. The mechanism of roller slit rolling has been analyzed from two stpects: the rolling force and uneven deformation of the rolled piece. the methods of roll pass design, roll pass dispose and guides design of the rolier slit rolling have been discussed.The economic benefits with the method of slit rolling has been estimated.
