摘要： A BOF process in which iron oxide units are added to the melt during the blow characterized in that the oxygen flow is reduced during pellet feeding and is replenished with inert gas so that the total gas flow remains the same as that designed to achieve optimum BOF performance.

摘要： A self-cleaning lance includes a lance body elongated along a longitudinal axis and having an upper end portion and a lower end portion, the lower end portion being spaced apart from the upper end portion along the longitudinal axis. One or more main nozzles are located proximal to the lower end portion and are adapted to release an oxygen-containing gas. One or more deskulling nozzles are spaced upwardly from the lower end portion and are adapted to release a deskulling gas. The lance body has a first portion that extends axially from the deskulling nozzles to the main nozzles and a second portion above the deskulling nozzles. The first portion has a smaller outer perimeter than the outer perimeter of the second portion. Each of the deskulling nozzles extends by an angle of not greater than 25 degrees with respect to the longitudinal axis.
