Because of time......
magnetite) and chromium-bearing vanadium-titanium magnetite (Cr-V- Ti magnetite), the determining criterion of which is about 0.50% [1] in China. The blast furnace process (BF) is the predominant route for the reduction of iron-bearing materials including ordinary vanadium- titanium magnetite now and in next decades and studies have indicated that the blast furnace could be used to process Cr-V......

:<正> Generally, the cooler life can determine the blast furnace life. The slag-metal skull frozen on the cooler can separate the cooler from the hot gas flow in blast furnace. The key problem is how to freeze liquid slag-metal on the cooler, and the main measure is to decrease the hot surface temperature of the cooler. The computational technology......
