摘要

通过热态试验,对比研究了铝、钛脱氧条件条件下吸附杆对钢液中杂质的吸附效果。试验结果表明,从单位面积夹杂物个数、面积比率、吸附速度三方面,镁钙质吸附杆对不同脱氧方式钢液中夹杂物均有较强吸附能力。钛脱氧钢液中夹杂物面积比率减小最大,吸附杆进行夹杂物吸附试验效果最好,试样中部、边部单位面积夹杂物个数与原脱氧钢锭相比降低了27.10%、32.55%,面积比率降低了51.58%、54.97%。
        The adsorption of impurities in molten steel under deoxidation conditions of aluminum and titanium was studied by thermal experiments.The experimental results show that the magnesia-calcium adsorption rod has strong adsorption capacity for inclusions in different deoxidation steels from the three aspects of the number of inclusions per unit area,area ratio and adsorption rate.The area ratio of inclusions in titanium deoxidized steel liquid decreased significantly.The number of inclusions per unit area in the middle and side of the sample was reduced by 27.10% and 32.55%,respectively, compared with the original deoxidized steel ingot and area ratio decreased by 51.58% and 54.97%,respectively.
