Sintering of Bahariya Iron Ore Using Anthracite at the Egyptian Iron & Steel Company

摘要

The partial and complete replacement of coke breeze with anthracite for sintering Bahariya iron ore at the Egyptian Iron & Steel Company (EISCO) was carried out. The best results were obtained for 25% of coke breeze replaced with anthracite. The specific productivity increased from 0.914 to 1.247 t/m(2) /h, the sinter strength increased from 88 to 90%, the porosity increased from 16.25 to 16.89%, and the reducibility increased from 62.94 to 65.42%. The sinter softening interval did not change, remaining 90 degrees C. Replacing 50, 75, and 100% of coke breeze with anthracite reduced the specific productivity, increased the FeO content of the sinter, increased the sinter strength from 88 to 94%, decreased the reducibility from 62.94 to 49.07%, and increased the softening interval from 90 to 113 degrees C.
