Abstract

In NKK Fukuyama Works, Hot Direct Rolling (HDR) process on No. 5 continuous casting machine and No. 2 hot strip mill is operated for the purpose of the saving of the energy and the materials, and the manpower. In the hot strip mill, the process is maintained by the technology of the prevention of temperature going down such as the heat insulating cover, the induction heater, and the technology of the schedule free rolling and the equalize of the product ability between the continuous casting and the hot strip mill, and the new computer system which controls these. By the achievement about each technology, the large quantities of production by HDR is operated stably, and the effect of the improvement about the quality is obtained.
