Synopsis : Kawasaki Steel has refurbished its production control systems in steelworks. The main objective is to establish the plan-oriented production control and pursue the continuation and synchronization of steel manufacturing processes. Weekly scheduling system provides a production schedule of each facility, integrating all products and all processes. The aim of this system is to shorten lead-time and keep a balance of material flows among facilities. As to steel-making, hot-rolling and cold-rolling systems, the level-up of all functions including functions of material handling and quality control has been realized in concert with the rationalization of equipment of production and material transportation. In addition, the newly developed standards management system helps the staff to maintain and apply the standards of production. The systems described above are being operated smoothly, and our purposes of refurbishment have been accomplished. This paper describes the whole aspect of the production control systems, focusing on sheets and strip and illustrating the systems in Chiba and Mizushima Works. |
