Improvement in the Efficiency of the Sintering Process in Pelletizing the Burden by Using Surfactant
In the sinter plant of «Ural Steel» was performed a complex of pilot-scale experiments to improve the pelletizing through the use of water-soluble organic surfactant when moistened of sinter burden. It was found that the use of surfactants provides improvement of granulometric composition of the sinter burden, its permeability in sintering and as result indicators of the sintering process, both technological and qualitative. Maximum efficiency is shown by the use of surfactants in the optimum moisture of the sinter burden (7 - 8 %) at a binder consumption of 1,2 - 1,6 l/h (the surfactant concentration in the aqueous solution of 0,3 - 0,4 ml/l).
