Abstract Because of the importance of steel or the element iron for the prosperity of the world it has been of great interest to look at the mutual relations between the modern metallurgical engineering and the state of process analysis under scientific and economical aspects. Process analysis comprises discontinuous and continuous procedures whereas more and more on-line techniques are required and of increasing importance. The paper illustrates the state of the art at the different metallurgical stages beginning with the blast furnace process and the steelmaking process routes. It will be shown that the highly sophisticated, computer-aided spectrometric and electrochemical methods applied play an essential role for process control and optimization. A survey is given about the research projects for direct analysis of melts, i.e. analysis without any sampling. Steel sheet production by rolling and annealing need analytical investigations as well as the metallic and organic coating processes. Of main interest are all questions related to surface properties. In this field the analyst has to face problems of inorganic and organic nature. It can be seen that coating is the last link of a process chain of continuous treatments in steel processing. Finally, the relations between material development and material analysis will be explained by example. Summarizing it will be stated that the modern, quality assured steelmaking and steel processing need the urgent assistance of process analysis for optimization. Process analysis and material analysis are of increasing importance for the scientific, technical, and economic progress.
