Synopsis : User's demand for the decrease in the traverse gauge deviation of hot-rolled strip is becoming more serious year after year, especially for the stainless or other special steel. To satisfy this demand, K-WRS (Kawasaki Steel-Work Roll Shifting) mill, which controls the strip crown by shifting a tapered work roll, was applied to Chiba No.1 hot strip mill in June 1983. and HC mill (High crown control mill, 6-high), equipped with the IMR shifting device and work roll bender, was installed in Mizushima hot strip mill in September 1983. As a result, the capability of controlling the strip-crown has been improved to produce the stainless steel hot coil, with a smaller strip crown and square cross section by applying the respective control methods used in K-WRS and HC mills. |
