Rolling method for hot strip
专利汇可以提供Rolling method for hot strip专利检索，专利查询，专利分析的服务。并且PURPOSE: To improve the yield of the strip as a whole, by applying the rolling work so as to make the breadth of the strip obtained from the top and the bottom of the slab wider than the breadth of the strip obtained from the middle part of the slab.
CONSTITUTION: When the slab arrives at the position of the breadth meter B
1 and the breadth of the slab is detected, this value is inputted to the process control computer (CMP) which then adjusts the roll gap E
i of the edging rolls E to E
j . For the purpose of increasing the breadth of the strip, obtained from the top and the bottom of the slab respectively in the length Lαr from their terminal end by the finish rolling, by the amount α on one side, the sheet breadth αr corresponding to this α is added. Accordingly, the breadth of Lα is specified by E
k =E
j +2αr. When the roll gap controlling schedule for the edging roll E is settled, CMP produces a signal to the conrollor CTR. Then the roughly rolled material is fed to the finishing mill for which the rolling schedule is set so as to make E
j to be the rolling breadth W
0 of the middle part; hereby, the sheet is finished into the desired shape that the length Lα of the top and the bottom parts is given the breadth W
0 +2α.
