摘　　要：分析了烧结矿中CS值(即CaO%+SiO2%)对转鼓强度的影响,以及在不同熔剂水平下,熔剂对操作负压的影响。随着熔剂量的增加,混合料透气性得到明显改善。为了得到适宜的垂直烧结速度,应当降低抽风负压。同时证明了在一定熔剂水平下,抽风负压为某一确定值时,烧结矿转鼓强度达到最高,高于或者低于此值,强度都会下降。The influence of the content of CaO and SiO2（CS） on the tumble strength, and the effect of the flux of different levels on suction pressure are analyzed . With the increment of the flux, the air permeability of the mixture is improved obviously. In order to get the proper vertical sintering speed, the suction pressure should be reduced. It is proved that on a certain level of the flux, when the suction pressure is controlled at a fixed value, the tumble strength is the best, otherwise the tumble strength would be descend.
