摘要
通过复吹转炉底枪布置优化试验研究,结果表明底枪采用合适支数,特别是采取非对称集中布置方式,更有利于加强熔池搅拌强度。三明钢厂100t复吹转炉底枪在国内首次采用非对称集中布置方案,实践应用结果表明冶炼终点各项技术指标得到很大的改善。
It is shown from the experiments for the bottom tuyere configuration optimization in combined blown converters that the bath stirring intensity can be enhanced by using a suitable number of bottom tuyeres and especially by positioning those bottom tuyeres in an asymmetrical and integrated configuration. Application of such an asymmetrical and integrated bottom tuyere configuration in the 100 t combined blown converter of Sanming Iron & Steel Co. is the first in the metallurgical sector of the Country and practical results show that all metallurgical parameters for the converter melting have been greatly improved.
