ABSTRACT The excellent properties of titanium pellet Z in the blast furnace hearth protection were determined by studying the composition, metallurgical properties and a over four years period of application practice of titanium-containing pellets(C&Z) and ores (J, G&D) in a domestic blast furnace. The reduction and softening-melting properties of titanium pellet Z were better than those of titanium lump ore G, D and J, and titanium pellet C. Under the condition of a titanium load of 7–8 kg TiO2/tHM, the fuel rate, pressure drop and slag ratio of the blast furnace using titanium pellet Z were better than that for the titanium-bearing resources. Using pellet Z had an obvious effect on the decrease of the hearth temperature and sustained stability. It was concluded that pellet Z was an excellent titanium-bearing burden for both laboratory research and industrial trial.

不同含钛炉料的冶金性能及护炉实践

摘要 通过研究含钛球团矿（C&Z）和矿石（J、G&D）的成分、冶金性能和四年多的应用实践，确定了钛球团 Z 在高炉炉膛保护中的优异性能。高炉。钛球团 Z 的还原和软化熔化性能优于钛块矿 G、D 和 J 以及钛球团 C。在钛负载为 7-8 kg TiO2/tHM 的条件下，燃料率、使用钛球团 Z 的高炉压降和渣比均优于含钛资源的高炉。使用Z丸对降低炉膛温度和持续稳定性有明显的效果。
