Automation of Sinter Charge Moistening during Pelletising

The influence of sintering charge moisture content on the indicators of sintering production of Ural Steel JSC was studied. It was found that the current pelletising and moistening regime has insufficient efficiency, not providing stable sinter charge with constant moisture and good gas permeability. The reason for sinter charge moisture fluctuations affecting pelletising and sintering indicators is the lack of an automatic system of moisture control and correction, which allows to respond promptly to changes in the properties of the charge supplied for pelletising. To increase the efficiency of pelletising, it is proposed to automate the process of moistening of sinter charge. The functional scheme of the automatic humidity control system is developed. The introduction of an automatic moisture control system will stabilise the quality of the sinter charge, which will improve the sintering indicators and quality of sinter.
