Development of coke-oven battery process management system at Rautaruukki Oy steelworks
- Rautaruukki Oy, Raahe (Finland). Research Center
Coke production in Finland is based on one coke-oven plant located at the Raahe steelworks. The first battery was brought into operation in Oct. 1987 and the second in Nov. 1992. The latest stage of development of the process management system in the coke plant at the Raahe steelworks is presented. When No. 2 battery was placed in operation the process computer was also changed to a larger capacity model. The process automation system is the same as it was at the start of coke production (Damatic). The necessary upgrades were made only when coke production was doubled. The heating control system has been under continuous development during the existence of the coke-oven plant. The first generation system was a statistical heating model (1987--1991). The second generation heating model is based on an energy balance calculated from the measured energy supply, amount of coal charged and coking time data, and also on the estimated coke temperature as a function of the coking index. The reliability and regularity of coke production has been developed using the dynamic oven scheduling system.
