| Synopsis: For the purpose to improve the productivity and quality of high value added steel products, various rolling technologies such as sizing press, fully continuous finishing hot rolling, edge drop control, have been developed on the basis of rolling theory, elasticity and plasticity theory, tribology, numerical analyses including FEM in the last ten years. In this paper, the research activities of the rolling technologies are described. Representative technologies are as follows: (1) Hot strip rolling: schedule free rolling, tribological technology and new technologies in No. 3 hot strip mill in Chiba Works, (2) Cold strip rolling: development of K-WRS mill and its application to edge drop control, and improvement of surface brightness of stainless steel strip, (3) H-shape rolling: dimension control and cooling contorl and (4) Numerical analysis of rolling. |
