Popis: Industrial experience of high-basicity sinter production in different raw materials conditions, in particular, at sintering of fine concentrates and hardly utilized wastes is a matter of an interest for sinter production specialists. At Enakievo sinter plant in 2014–2018 under very complicated conditions of non-regular supplies of iron ore raw materials, forced utilization of a big amount of metallurgical wastes, non-satisfactory equipment technical state, a production of solid enough high-basicity sinter was provided. High-basicity sinter indices and sintering parameters for the period mentioned quoted. An analytical estimation of main stages of sinter production state and some kinds of technological equipment made. Peculiarities of the technology and production parameters of high-fluxed sinter at utilization of different iron ore concentrates, wastes and special additives to sinter burden considered. Scientific and practical recommendations for technology improving and modernization of technological equipment, used for the sinter burden preparation, elaborated. Based on these studies and authors practical experience, methods of sintering non-uniformity along the sintering machine width overcoming proposed: rational burden layer forming in the charging hopper and burden layer profile along the pallets width; compaction of the burden layer in peripheral pallets zones. Measures proposed for modernization of the drum-pelletizer and of the charging hopper. Description of the facility for rational burden preparation for sintering quoted.
