日本住友金属工业公司开发出用廉价原料生产高质量低渣烧结矿的烧结矿生产新技术，将烧结矿中渣的代表性成分SIOZ大幅度减少到4．6％，使高炉渣年产生量减少约20万t。开发该低渣浇结矿制造技术旨在减少高炉渣发生量和增加高炉喷煤量，以适应解决地球暖化问题和延长焦炉寿命；该 Sumitomo Metal Industries Co., Ltd. of Japan has developed a new sinter production technology that produces low-quality sinter ore with low-cost raw materials. The SIOZ, a representative component of slag in sinter ore, has been drastically reduced to 4.6% and the annual production of blast furnace slag has been reduced About 200,000 t. The development of the low residue pouring ore manufacturing technology aims to reduce the amount of blast furnace slag and blast furnace coal injection to adapt to address the global warming problems and extend the life of coke oven;
