A NOVEL PELLET-SINTERING TECHNOLOGY OF MANGANESE FINES
Traditional sintering process of manganese fines generally requires high fuel consumption and gives poor sinter quality.Therefore,developing new agglomeration technologies of manganese fines is of great significance to reduce the production cost of ferroalloy,expand the source of raw materials and promote the low-carbon and green development of ferroalloy industry.In this paper,a new pellet-sintering process of manganese fines is proposed and compared with the traditional sintering process by conducting sinter pot tests.The results show that,compared with the traditional sintering process,the new pellet-sintering process can increase the sinter tumbling strength by 4.35%and the utilization coeffi-cient by 16.22%,while the solid fuel consumption is reduced by 21.79%.In addition,the pellet-sinter productions of manganese fines exhibit better decrepitation-resistant performance and high-temperature softening-dripping performance than the manganese-bearing sinter obtained from the traditional sintering process.The findings will provide important ref-erence for realizing low-carbon sintering and enhancing submerged arc furnace smelting of manganese ores.
