Influence of burden properties and coke quality on the operating results of big blast furnaces
- Centro Sperimentale Metallurgico, Rome, Italy
A study was undertaken to investigate the way the quality of the iron-bearing materials and coke affects blast furnace performance. Laboratory tests are described which studied low temperature degradation, reducibility, and softening underload of the sinter and pellet material and reactivity of the coke. In order to establish the best burden materials properties, a performance test of the Taranto No. 5 blast furnace was run involving planned variations of FeO, MgO, and CaO/SiO/sub 2/ ratio in the sinter and the use of acid and self-fluxing pellets. Modifications in coke quality occurred in the supply and these were monitored also. Blast furnace productivity, gas distribution, permeability, thermal state of the refractories, and the fuel rate were all examined. Statistical analysis of the results revealed significant relationships between these parameters and the quality indexes of the ferrous materials and coke and these are discussed. (CKK)
