摘　　要：通过小型烧结杯制取不同碱度的烧结试样,采用高温加热炉对烧结试样分别进行560℃热处理和弱还原处理,利用GB/T13242-91中小转鼓分别测定烧结试样的冷强度,热处理和弱还原后烧结矿强度。通过转鼓试验所得数据,总结出碱度与烧结矿冷强度,热处理后烧结矿强度和弱还原后烧结矿强度的关系。并在此基础上,再从理论分析研究烧结矿在高炉内破损机理。In the test we use small cup make some different basiclty smter samples, ana then aaopt mgn temperature electric furnace to do heating treatment and weak reduction respeetiveky to the sinter samples. Make use of the small drum which refer to GB/T13242-91 to measure the normal strength of the sinter, af- ter heating treatment strength and weak reduction strength of the sinter. From the drum test datas ,we summarize the relationship between the basicity and the sinter normal strength, after he^ting treatment strength and weak reduction strength of the sinter. Based on which, we take advantage of the theory to study the breakage mechanism of the sinter in the BF.
