Process Technology International (PTI) has recently developed and commissioned an innovative system for lime introduction to the EAF. This paper describes the practical operating results achieved when this innovative, lime injection system was installed at a 120 ton EAF located in USA. The lime systems convey hi-cal lime and dolo-lime approximately 40 meters from a pressurized vessel to PTI’s QuadJetTM injection burners mounted in a PTI JetBOxTM on the side wall of the EAF. Lime was originally loaded in loose form with the scrap into the charge bucket. This method of loading the lime resulted in a loss of material to the operation floor and to dust evacuation system. The lost material increased the amount of lime consumed, caused a housekeeping mess and posed a safety hazard to the operators in the melt shop.
