【摘要】 由于常规的沉淀脱氧工艺会使脱氧产物残留在钢液中,钢液夹杂物增多,钢水洁净度降低,为了提高钢液纯净度,笔者采用将液化气直接作用于钢液,观察钢中氧含量的及夹杂物的变化情况。研究结果表明:将液化气通入钢液中,钢水氧含量有明显的降低,液化气流量增大能提高钢水脱氧速率;液化气中混有氩气时能提高脱氧率;液化气脱氧与Al脱氧相比能降低钢液夹杂物数量,提高钢水洁净度。更多还原

【Abstract】 Since the conventional precipitation the deoxidation process causes residual deoxidation product in the liquid steel,the liquid steel inclusions increased cleanliness of molten steel decreases,the author uses the direct action of the liquefied gas in the liquid steel,observation steel oxygen content,in order to improve the purity of the liquid steeland inclusions changes.The results show that:the liquefied gas is passed into the liquid steel,and significantly reduce the oxygen content of molten steel,the liquefied gas flow rate is increased can improve the rate of deoxidation of molten steel;liquefied gas mixed with argon can be improved when the deoxidation;liquefied deoxidation with Al deoxidationcan be reduced compared to the number of inclusions in molten steel, molten steel cleanliness.更多还原
