THE VERIFICATION OF MODELS FOR INDIRECT MEASUREMENT MELT TEMPERATURE IN STEELMAKING PROCESS
Abstract
In the paper is described system of indirect measurement of melt temperature (SIMT) in the converter. The steelmaking process belongs to very complicated metallurgical processes. Steelworks annually make millions of tons quality steel for home and foreign market. Quality and quantity of produced steel is needed to rise so steelworks are able to compete in world in this part of an industry. One of the options how to raise the quality in this technological process is information about temperature during melt. Temperature at steelmaking process in converter is very important variable. The task of SIMT is continually measurement of temperature during melt. They were designed several regression models, which are different in structure. Inputs of models are direct measured variables from steelmaking process for example temperature and content of gas converter, the height of the jet, volume flow of oxygen. The output from models is indirect measurement of temperature during melt. This paper is focused on the verification of models and comparison their results.
