Experimental Research on Optimization of Sintering Mixture with Low-grade Complex Ore from Xinjiang

In order to utilize the lean ore resources rationally and optimize mixture,experimental schemes of sinter mixture were designed and carried out under different basicity,different carbon content as well as different fuel particle size by the sintering cup.The results show that the sinter strength decreased by 5%,low temperature reduction disintegration index （RDI） is the lowest and the natural degradation index of the sinter was higher when sinter basicity is between 1.65 and 1.75.The sinter strength increases when sinter basicity varies from 1.75 to 2.0.Meanwhile,the sinter strength and RDI_+3.15 has been improved with the carbon content increasing.The sinter strength and RDI_+3.15 also went bad with the fuel particle size getting smaller.
