高碱度高氧化性的转炉熔渣在出钢过程中流入钢包,将严重的污染钢液、烧损合金元素和浸蚀钢包内衬。挡渣出钢就是要减少出钢过程中流入钢包内的渣量,从而减轻熔渣的上述有害作用。出钢过程中首先流入钢包的熔渣,是在倒炉出钢时渣面先经过出钢口而流出的。这部分熔渣虽然量小,但与钢 High alkalinity and high oxidizability of converter slag flow into the ladle in the tapping process will be a serious pollution of molten steel, burning alloying elements and erosion ladle lining. Slag tapping is to reduce the amount of slag flowing into the ladle during tapping, thereby reducing the above-mentioned detrimental effect of slag. During the tapping process, the molten slag that flows into the ladle first flows out through the tapping hole when the steel is tapped during the tapping process. Although this part of slag is small, but with steel
