1.前言由钢锭到钢材一般要经过两次加热,甚至更多。在多次加热过程中,金属的总烧损率可达3～6％。大量氧化铁皮的产生不仅降低了成材率,而且引起一系列不良后果,如轧制时钢表面的氧化铁皮被压入钢坯或钢材,影响其表面质量,氧化铁皮落入炉内,不仅影响炉体寿命,而且清除时费工耗能,降低了炉子作业率;过多的氧化铁皮造成沸腾钢锭气泡暴露,降低钢锭合格率等。钢锭、钢坯的氧化烧损是一项巨大的金属消耗和经
1. Introduction From ingot to steel generally go through two heating, or even more. In many heating process, the total metal loss rate of up to 3 ~ 6%. The production of a large amount of scale not only reduces the yield, but also causes a series of undesirable consequences. For example, the scale on the steel surface during rolling is pressed into the billet or the steel to affect the surface quality of the scale, and the scale falls into the furnace, Life expectancy, but also eliminates the time consuming energy consumption, reducing the furnace operating rate; too much oxide scale caused by boiling ingot bubble exposure, reduce the passing rate of steel ingot. Oxidation loss of ingots and billet is a huge metal consumption
