Through thermal experiments,the adsorption of impurities in molten steel under the condition of aluminum deoxidation was studied on the three kinds of adsorption rods,ie,magnesium-zirconium,magnesium-chromium and magnesium-calcium.The experimental results show that from the aspects of the number of inclusions,area ratio and adsorption rate per unit area,the adsorption capacity of magnesium calcium adsorption rods on inclusions in liquid steel is stronger than that of magnesium zirconium and magnesium chromium adsorption rods.The number of inclusions per unit area at the middle and edge of the sample reduced by 29.66% and 39.26% compared with the original deoxidized steel ingot,and the area ratio reduced by 56.83% and 64.33%.The inclusion absorption velocity was 0.34 μm/s.
