COKING DUST REMOVAL COKE POWDER INSTEAD OF CARBURIZING AGENT IN STEEL-MAKING PRODUCTION
The carburizing agent required for steel-making requires a high fixed carbon content,low ash and volatile content,and low sulfur content.By conducting physical and chemical analysis and testing on the dust removal coke powder generated by the coking system,the dry quenching dust removal coke powder that is closest to the physical and chemical performance requirements of the carburizing agent and has a low price is selected.The method of packaging in bags directly into the steel ladle is used to replace the carburizing agent in the early stage of stee-lmaking.A 100 kg dry quenching dust removal coke powder can increase the carbonization of the steel by 0.048％.Through production practice,the use of dry quenching dust removal coke powder instead of carburizing agent has no impact on steel quality,and the cost per ton of steel is reduced by 1.25 yuan/ton.
