PRODUCTION OF HIGH-QUALITY SELF-FLUXING SINTERED ORE

PURPOSE:To easily obtain high-quality self-fluxing sintered ore by adding limestone to an ore group and pelletizing the ore in one system of a pelletization stage for sintering raw materials, then adding silica stone to the ore group and pelletizing the ore in the other system, thereafter, by mixing and sintering both. CONSTITUTION:Fine ore 12, returns 13, silica stone 14, and fine coke 15 which are the sintering raw materials are fed from a bin 11 of the 1st system to a line 16 and are mixed by a mixing pelletizer 17 to form pellets A. Fine ore 19 and the limestone 20 are fed from a bin 18 of the 2nd system to a 2nd line and are mixed by a mixing pelletizer 22 to form pellets B. The pellets A are preferably formulated to satisfy the conditions of CaO/SiO2
