Abstract

The use of titanium bearing materials is well known for the protection of the hearth against premature wear.The industrial application and different ways of input and effectiveness of lump ilmenite and synthetic TiO2 (RUTILIT) will be described. There exist typical differences in the thermodynamically and kinetically behavior of the natural ilmenite-system and the synthetic RUTILIT-system. The result of this topics will be combined with the evaluation of economic conditions of the different TiO2- systems, e.g. the market-prices of different product-systems, the specifical handling costs concerning e.g. the special input technologies, the metallurgical effectiv in the blast furnaces, the prolongation of the life time of the hearth of blast furnaces, and also the metallurgical effect on liquid iron and the slag by the added titanium containing material. The comparison of the industrial results of different applications shows the advantages of the use of the synthetic TiO2 by injection technology. This paper is a common report from AG der Dillinger Hüttenwerke (ROGESA), Dillingen (Germany) and SACHTLEBEN CHEMIE GmbH, Duisburg (Germany) and shows the result of using titanium containing products in the blast furnace no. 4 and 5.
