Synopsis : A process instrumentation and control system, whose main aims were the improvement of the product quality and security of stable production, was introduced to the wire rod and bar mill of the Mizushima Works, synchronized with the installation of new rod rolling facilities in September, 1984. The system, which consists of a process computer system, process control DDC systems and various sensors, controls processes from the entry of the reheating furnace to the coil finishing line, closely exchanging many items of information with an on-line operational computer system and DDC systems for the electric equipment, etc. Among the functions of the system, computer control of the reheating furnace, automatic setting up of the rolling equipment and high-density data gathering are the major ones, which have greatly contributed to the automatization and stabilization of the rod and bar production, and reinforcement of the quality assurance system of the mill. |
