【摘要】 湘钢2号(750m~3)高炉在模型研究与工厂生产实践相结合情况下进行中心加焦操作,取得了技术指标有较大提高及高炉炉况稳定顺行等效果,操作结果表明,中心加焦量一般以10％较为合适,中心加焦角α焦=11°左右为好,大料批倒装是进行中心加焦较为合适的料制。更多还原

【Abstract】 The central coke charging at No.2 blast furnace (inner volume ;750m3) of Xiangtan Iron & Steel Co.was carried out based on the model test.As a result the blast furnace operation indexes were improved greatly,as well as the stable and smooth operation was kept.The operation result indicates that the amount of central coke charging of 10% and the angle of central coke charging of approximately 11?are available and the large batch reversed filling sequence is suitable for central coke charging at the No.2 blast furnace.更多还原
