摘要
转炉冶炼终点钢水中的氧是产生钢中夹杂物的根源,对钢的洁净度有着不利的影响。为了加强转炉终点氧含量的控制水平,提高产品的内部质量。通过对某厂转炉冶炼IF钢现场试验研究,分析了转炉终点碳氧含量的分布状态,研究了碳含量、炉龄、终点温度和氧耗量等因素对终点氧含量的影响规律,并提出了降低转炉终点氧含量的技术措施。
Oxygen activity at blowing end-point of BOF steelmaking is the main source of producing nonmetallic inclusions and has bad influence on steel cleanliness. In order to increase the control of oxygen content at blowing end-point of BOF steelmaking and improve products＇ inner quality, experiments are done during a BOF steelmaking to produce IF steel in a plant. The content of carbon and oxygen at blowing end-point is analyzed, the effect of content of carbon, BOF age, end-point temperature and consumption of oxygen on the content of oxygen at blowing end-point are studied and decreasing measurements of end-point oxygen content are put forward.
