摘 要：針對(duì)中厚鋼板軋制展寬過程中呈現(xiàn)的不規(guī)則形狀提出了PVPC軋制法，以期達(dá)到控制板型提高成材率的目的；針對(duì)極限規(guī)格板坯無法正常展寬的情況提出了角軋工藝，在提高成材率的同時(shí)擴(kuò)展了產(chǎn)品的供貨尺寸范圍。

Abstract：This paper suggest PVPC rolling method for the present irregular shape in the process of the medium thick steel plate broadside rolling， in order to achieve the goal of control board type to improve the rate of finished products; angle rolling technology was proposed for the extreme dimension slab can't normal broadside rolling， expand the supply size range of the product. while to improve the rate of finisheg products.

Key words：medium thick steel plate；PVPC rolling；angle rolling

在傳統(tǒng)的中厚鋼板軋制過程中，橫軋階段一般處于自由展寬狀態(tài)，輸出鋼板板型側(cè)邊呈現(xiàn)棗核型或頭尾呈現(xiàn)舌型等不規(guī)則形狀，導(dǎo)致后續(xù)精整切定尺齊四邊工序產(chǎn)生較大的邊角余料損失（約占10%～12%）。（剩余1617字）
