摘　　要：Nozzle blocking was eliminated by calcium-treated liquid steel through changing the chemical and phase composition of alumina inclusions in aluminium-killed steel.Three different methods were applied to determine the composition of inclusions in liquid steel:total oxygen content samples,sampling spoon samples,and 'lollipop' steel samples.The results show that calcium modification of liquid steel influences the inclusion composition varying from 2wt% to 14wt% depending on the method used.The composition of inclusions contains mainly Al 2 O 3-CaO only,or is associated with SiO 2 or MgO depending on the initial input.The methods used in this study are indicators of the inclusion composition but can be improved to quantify the inclusion size. 关键词：钢液钙处理夹杂物测定钢铁样品铝镇静钢喷嘴堵塞总氧含量 SIO2
