一、引言沸腾钢生产主要由于脱氧剂及钢锭模的消耗较少,而且轧钢时头部需要切除回炉的百分率低,成本通常比镇静钢低得多.以鞍钢1956年成本为例,镇静钢锭比沸腾钢锭成本高5.8%,镇静钢坯比沸腾钢坯成本高14.4%。同时,镇静钢平均此沸腾钢多切头10%左右,意味着生产镇静钢时炼钢和初轧的生产能力比生产沸腾钢时降低约10%.可见沸腾钢与镇静钢比较在成本和生产能力的利用上都具有重大的优越性.此外,用沸腾钢轧
I. INTRODUCTION Boiling steel production is mainly due to less consumption of deoxidizer and ingot mold, and the lower the percentage of heads that need to be removed for reheating when rolling, the cost is usually much lower than that of killed steel.In Anshan Iron and Steel 1956 cost example, the calm steel ingot ratio The cost of boiling ingot is 5.8% higher, and the cost of calming slab is 14.4% higher than that of ingot billet. At the same time, the average calming steel is about 10% more than that of the calming steel, meaning that the production capacity of the steel making and the first rolling when producing the calming steel is reduced by about 10% compared with the production of the boiling steel. The use of capacity has great advantages. In addition, the use of boiling steel rolling
