摘要： An iron-making sintered ore having a cross section wherein at least 80 % of a solid part except for non fused residues of the sintering materials other than pisolitic iron ore is composed of a densified pisolitic iron ore enclosed by fine calcium ferrite with a width of 10 mu m or less, or of hematite particles and calcium ferrite which bonds the hematite particles together while holding traces of the pisolitic iron ore, or of a mixture thereof. The production process comprises sintering iron-containing starting material such as iron ore, carbonaceous material, water, and the like in a sintering machine by using 40-70 mass % of pisolitic iron ore and a high-grade iron or containing 1.5 mass % or less of SiO2 as the iron-containing starting material other than returns.
摘要翻译：一种具有横截面的制铁烧结矿，其中至少80％的固体部分除了非侵入性铁矿石以外的烧结材料的非熔合残余物是由精细铁素体包围的致密的硫化铁矿石组成，或者赤铁矿颗粒和钙铁氧体，其将赤铁矿颗粒粘合在一起，同时保持硅质铁矿石的痕迹或其混合物。制造方法包括：在烧结机中，通过使用40-70质量％的异型铁矿石和高品质的铁，或者含有1.5质量％的铁，将含铁原料如铁矿石，碳质材料，水等烧结，或少于作为含铁起始材料的SiO 2作为回收。
