Resumo

Process Technology International Inc. (PTI) has commissioned several pneumatic, sidewall lime injection systems for use in Electric Arc Furnaces (EAF). The PTI lime injection systems convey hi-cal lime and dolo-lime through PTI’s injection burners mounted in a PTI JetBOxTM on the side wall of the EAF. The PTI method of injecting hi-cal lime and dolo-lime through the EAF sidewall is superior to other methods of adding lime to the EAF. The major advantage of the PTI system is that lime is directly injected to the slag metal interface during furnace power on time. Other methods of adding lime to the EAF result in loss of material to the operation floor, the de-dusting system and pose a safety hazard to the operators. This paper summarizes the results achieved at four EAF steel mills after the installation of the PTI lime injection system. The reduction in operation cost, greater control of the process and increase to operator safety are highlighted
