摘　　要：通过对唐钢第一钢轧厂转炉冶炼炉次进行追踪、统计和分析,认为转炉喷溅、渣量和熔渣铁损、扒渣、入炉冷料用量和补炉次数等因素是影响转炉钢铁料消耗的主要因素,提出了改进吹炼工艺,降低转炉喷溅次数,提高操作水平;强化冶炼,提高一次拉碳命中率、强化底吹气搅拌降低终渣(FeO)含量和炉渣带铁量;增大含铁冷料用量,加强炉况管理、减少补炉次数的改进措施。With tracing,statistics and analysis of heats of converter smelting in No.1 Steel Rolling Mill of Tang Steel,it is considered that converter spitting,slag amount,iron loss in smelting slag,skimming,into-converter cold material quantity and times of fettling are the main factors to affect the consumption of iron and steel material for converter.It is proposed the following improving measures： improving blow process,reducing times of converter spitting,improving operation level;strengthening smelting,raising hits of percentage of once catch carbon,strengthening bottom-blown air and stirring to decrease end slag（FeO） content and bearing-iron amount in slag;increasing consumption of iron-bearing cold material,strengthening management of furnace condition,reducing times of fettling.
