USE OF PREREDUCED ORE IN A BLAST FURNACE |
摘要 |
<p>An improved method for operating a blast furnace wherein a portion of the charge is prereduced iron ore with a relatively low metallization in the range of 75% to 90% and a relatively high carbon content in the range of 1.5% to 4.5% by weight. The composition of the sponge iron is selected so as to realize an increase in the production of pig iron and a decrease in the consumption of coke while simultaneously maximizing the overall economy and efficiency of the blast furnace operation. In a preferred embodiment of the invention at least 80% by weight of the carbon content in the sponge iron used as a portion of the charge to the blast furnace is in the form of ferric carbide.</p> |
