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.
