INCREASE IN EFFICIENCY OF AGGLOMERATION PROCESS UNDER THE CONDITIONS OF MODERN REQUIREMENTS TO DEVELOPMENT OF INDUSTRIAL TECHNOLOGIES

Modern development of technological level of the metallurgical industry is connected with reserve depletion of raw materials in crust, need of its enrichment to compliance to requirements of technologies of further processing with preliminary sintering. The new model of development of industrial technologies along with sharp reduction of consumption of resources imposes basic requirement of increase in the importance of ecological tasks. It means introduction in technology of preparation of raw materials for melting different dispersive granular materials and waste of metallurgical production connected with gas emission, dust, formation of slags, slimes. In these conditions, problematic issue of agglomeration of burdening materials of stock is the low specific productivity of agglomerative machines connected with difficulties of nodulizing of iron ore and other granular materials of sinter burden. This work submits analytical review of information on a condition of the main question of preparation of metallurgical raw materials for domain melting by agglomeration: increase in efficiency of agglomeration process in the conditions of modern requirements to development of industrial technologies. The short characteristic of a condition of iron ore base “Arcelormittal Temirtau”, regional problem questions of agglomeration are provided in the work and the review of the most important scientific and technical achievements and tendencies of development of technology of agglomeration for the last decade is included.
