چکیده
Toshiaki Takahashi Takaaki Ozawa Hajime Takahashi OVERVIEW: Steel industry control systems tend to be large, comprising motors, drives, PLCs, and process computers among other components. In addition to reliability, they require the speed of response to perform realtime electrical and mechanical control. To achieve this, Hitachi uses the latest computing and information technology. Hitachi is also working on innovations in control and system technologies to improve the efficiency of equipment operation and the quality of steel strip. Hitachi has supplied numerous control systems to steel companies in Japan and overseas since the era in which steel was considered the mainstay of industry. In addition to making extensive use of universal technologies in recent years to facilitate expansion into global markets, Hitachi has also been developing both operations technology and remote maintenance techniques for delivering added-value after-sales services to meet the needs of emerging economies where new rolling mills continue to be constructed.
