Popis: Existing systems for the control of mould level of continuous steel casting in Czech Steelworks have had problems with the stability of the steel level position. A new control algorithm is designed on the basis of mathematical modelling and digital simulation. This should better satisfy the actual demand on the control quality. A PI controller with a variable gain and dither signal was used. During several months of practical tests and the experimental tuning of the controller, parameters were determined regarding the required shape time diagram of the steel level for all types of steels, resulting in very good slab surface quality.
