Based on the above premise, this design bine Tang steel 1450 ,Ben steel 1700, Bao steel 1580 and An steel 1780 hot rolling production line to design million ton traditional hot continuous rolling workshop. In this paper it introduced the heat furnace, the rough rolling in detail, the heat box, the finish rolling, the laminar cooling, the curl and so them, The finishing mill still selected the big cross section memorial arch and the high tonnage rolling stand, and chose CVC mill, work roll bend technique and automatic gauge control to control strip shape and thickness. Moreover, in order to raise the temperature of rolling metal and reduce the difference temperature between the tail and the head of rolling metal, I establish a hot curl box between the rough rolling and the finishing rolling. The coefficient in this design and parts of formulas e from actual experience. Keywords conventional continuous rolling, heat box, laminar cooling, automatic gauge control 目 錄 III 目 錄 摘 要 .............................................................................................................................
