Abstract

PURPOSE: To decrease the difference in the elongation between a base metal and cladding metal and to improve yield by increasing the rolling reduction at the bite-in end of rolling rolls within the same pass of a process for rolling.
CONSTITUTION: The rolling reduction at the bite-in end of the rolling material is determined at 14mm and the rolling reduction at the bite-off end at 2mm to form a slope to the rolling material in the 1st pass of cross rolling after the end of the forming pass of the rolling material consisting of a stainless steel for the cladding metal and carbon steel for the base metal. The material is rolled at 14mm rolling reduction at the bite-in and 2mm rolling reduction at the bite-off end so as to remove the previous slope in the 2nd pass (reverse pass) in succession thereto. The similar rolling is executed in the 3rd and 4th passes as well and ordinary rolling is executed in the 5th pass to decrease the difference in elongation in the transverse direction. The differences in the elongation in the longitudinal and transverse directions of the product can be decreased if the cross helical rolling is executed in the forming pass and finishing pass as well in addition to cross rolling pass.
