POSSIBILITIES OF APPLICATION THE TITANIUM ORE INTO THE SINTERING MIXTURE
Abstract
Titanium-bearing burdens are commonly introduced into blast furnaces to protect the hearth and, consequently, extended operating campaign life. Application of titanium ores as part of sintering mixture is one of the way for implementation of titanium into blast furnace. The objective of the present work was to appreciate possibilities for application of supplied titanium ore into the sintering blends. There was studied effect of titanium addition and granularity of titanium ore on sinter properties and technological parameters. There was also sintered mixtures on the base of sintering ore and on the base of concentrate. Each of them was added constant content of titanium ore. The basicity of monoblends was from 0.62 (without of limestone and dolomite) to 2.00. Monoblends on the base of concentrate had positive effect on total content of iron. In the case of mixtures without bases addition was observed higher temperatures in sintering bed because of endothermal effect could not be used. Laboratory analyses indicated that introduction of tested titanium ore did not have a significant influence on productivity. Increasing the titanium ore levels up to 16 % had no significant influence on sintering quality but a significant deterioration in sinter strength was recorded. Results also showed that a granularity of investigated titanium ore had no clear affect on sinter quality.
