Instrumental Methods of Analysis for the Process and Quality Control in Iron and Steel Industry

Analytical control of the various processes in iron and steel production has long been recognised as essential to successful operation and is in daily practice throughout the industry.
To meet the close specifications of chemical composition and physical properties demanded by the customer, rigorous control over raw materials, intermediate products and the finished steel is exercised to an increasing extent in the chemical and metallurgical laboratories of the iron and steel works.
Apart from quality control of the final products, analy-tical data, coupled with physical tests in some instances, provide vital information for the steel maker in the attainment of increased production and trouble free-operation. In other words analytical data is essential to
ensure product quality as well as for process control by ensuring maximum economy of materials and minimum wear on furnace refractories.
