Efficiency Improvement of Sintering as a Result of Surface-Active Substance Use in Pelletizing at the JSC "Ural Steel"

Abstract:

A set of pilot experiments to improve pelletizing through the use of the sinter charge humidification of water-soluble organic surface-active agents (surfactants) has been performed in the sintering plant JSC "Ural Steel". It has been found that the surfactant use provides an improved granularity of the sinter charge and increases its gas permeability during sintering that ensures a better technology and quality. The maximum efficiency from the surfactant use is manifested in the area of the optimum moisture content of the sinter charge (7 – 8 %) at a flow rate of the experimental binder 1.2-1.6 l/h (surfactant concentration in an aqueous solution is 0.3 – 0.4 ml/l).
