摘　　要：通过烧结料层风量的大小是决定烧结机生产能力的重要因素之一.在抽风机能力不变的情况下,要增加通过料层的空气量,就必须设法减小物料对气流通过的阻力.在实验的基础上,研究了烧结杯安装支撑板后对料层透气性的改善效果,进而考察了对烧结生产率、烧结矿转鼓强度、成品率、粒度组成和冶金性能等的影响.实验表明,安装支架后,烧结生产率明显提高,最高提高23.15%,尽管转鼓强度略有下降,但仍可满足生产要求,而冶金性能也得到改善.Gas volume through the sinter bed is one of the very important factors that determine the productivity of sintering. When the capacity of the exhaust fan is fixed, the increase of gas volume through the sinter bed can be only realized by the reduction of sinter bed resistance to airflow. On laboratorial conditions, the effect of bed permeability improvement under the condition of standsupport sintering was studied, and the productivity, drum index, product yield and size composition were investigated quantitatively. The results showed that applying stand-support during sintering, the productivity increased by maximum 23.15 % and the drum index decreased slightly, while it still met the demand of ironmaking. The metallurgical properties of sinter were improved at the meantime.
