Preface
In Japan, the steel making industries have developed rapidly in the 1960s and 1970s. The production of steel has exceeded over 100 million tons, and the rolling speed in cold sheet rolling has exceeded over 2000 m/min. Then, the flow stress and the coefficient of friction in cold steel sheet rolling with higher rolling speed were unknown parameters, so that the parameters had intensely investigated in Japanese steel making industries. In 1970s, the joint researches on the flow stress and the coefficient of friction in cold sheet rolling with higher rolling speed were carried out in ISIJ. From these joint researches, the stress-strain curve involving the strain rate and the temperature for higher speed rolling was developed, and the experimental relationship between coefficient of friction and rolling speed over 2000 m/min was derived. In 1980s, the friction pick up in cold sheet rolling had intensely investigated in Japanese steel making industries. The evaluation testing of the friction pick up using tribo-simulators was carried out, so that it could be understood that an interface temperature among the tribological parameters was most important to evaluate the antiseizure property. Then, the microscopic analysis of the interface phenomena between roll and workpiece has been carried out from the viewpoint of the control of surface properties in ISIJ. In ho
