Experience and results of new heating control system of coke oven batteries at Rautaruukki Oy Raahe Steel
- Rautaruukki Oy Raahe Steel (Finland)
The latest development and results of the heating control system at Raahe Steel are presented in this paper. From the beginning of coke production in Rautaruukki Oy Raahe Steel (October 1987) the heating control systems have been developed. During the first stage of development work at the coking plant (from year 1987 to 1992), when only the first coke oven battery consisting of 35 ovens was in production, the main progress was in the field of process monitoring. After commissioning of the second stage of the coking plant (November 1992), the development of the new heating control model was started. Target of the project was to develop a dynamic control system which guides the heating of batteries through the various process conditions. Development work took three years and the heating control system was commissioned in the year 1995. Principle of the second generation system is an energy balance calculation, coke end temperature determination and dynamic oven scheduling system. The control is based on simultaneous feedforward and feedback control. The fuzzy logic components were added after about one year experience.
