Abstract:
This work is aimed at the effect of titanium bearing materials on thermal state in the hearth of blast furnace. With the purpose of the carbo-nitrides production, the raw materials with titanium content, which protect the lining of the blast furnace hearth against wear and in that way prolonging its working life, are added into the blast furnace. The campaign life of a blast furnace depends greatly on the lifetime of hearth refractory lining. Hearth refractories are represented mainly by carbon bricks or carbon ramming mixes. In the blast furnace No.1 in U.S.Steel Košice is refractory wear monitored by four levels of termocouples. Once the critical value of temperature is crossed, necessary precautions must by done e.g. charging of titanium-bearing materials in order to create a protection layer of titanium carbonitrides.
