This paper put forward the design theory and method of backup roll on Steckel mill, according to the actual rolling process in Shaogang, VCR (Varying Contact-Length Backup Roll) was designed of 3450mm four-high mill, and industrial test has been carried out. The test results show: the new backup roll improve the shape control performance, increase the transverse thickness deviation and the plate yield, and greatly cut down the spalling of roll.
