ABSTRACT:
Standard hot strip mills include a roughing train and a finishing train having a plurality of finishing stands F-1, F-2, F-3 . . . F-X. F-2 is eliminated from the finishing train and F-1 is converted into a reversing mill. Coiling furnaces are installed on either side of F-1 with the downstream coiling furnace replacing F-2. The resultant reversing mill and coiling furnaces are arranged so that a transfer bar is first reduced as it passes through F-1 in a forward direction and coiled in the downstream coiling furnace, then further reduced as it is passed in a reverse direction through F-1 to the upstream coiling furnace, then further reduced as it is passed the third time through F-1, and then further reduced to the final gauge as it passes successively through F-3 and the remainder of the finishing stands in the finishing train.
