Influence of surface-active substances on the processes of <\/strong>agglomeration when the secondary resources are using<\/strong><\/h3>\n

Abstract.<\/strong> A promising method of intensifying the process of sinter preparation preparation was investigated by using surfactants as an additional binding material. It is shown that surfactants provide efficient compaction of charge materials. The use of water-soluble surfactant additives (aminocrylate of
\nvarious compositions) when moistening the charge in the blending and pelletizing of charge materials positively affects the sintering performance and the quality of the finished sinter. An increase in the strength of the agglomerate during recovery, a decrease in abrasion, and an increase in the temperature of
\nthe maximum melt filtration were noted. An increase in the recoverability of the agglomerate and the associated decrease in the \u2015aggressiveness\u2016 of primary slags were also observed. When using surfactants, the duration of the process was reduced, and the vertical sintering rate increased from 1.0-1.8% to 6.1- 8.5%. The yield of the charge has increased by 0.4-2.4%, the strength index – by 0.4-2.2%. Analysis of the results of laboratory studies confirmed that the introduction of surfactants in moisturizing water can improve the quality of the mixture. In particular, the gas permeability of the charge is improved, the best
\nconditions for burning solid fuel and the process of liquid-phase sintering are provided, and the strength properties of the finished product are enhanced. The involvement of a part of metallurgical wastes in the fermentation domain complex allows to significantly expand the resource base of iron ore components, reduce the cost of input raw materials and improve the environmental situation.
\nKeywords:<\/strong> sintering mixture, secondary resources, surface-active substances (surfactants), sinter quality.<\/p>\n
