为进一步提高钢水洁净度，减少夹杂物对产品性能的影响，在实验室研究的基础上，采用含Mg合金包芯线在优质高碳钢上进行了脱氧工艺的工业性试验研究，并对不同脱氧工艺条件下钢中T[O]和夹杂物组成、形貌和尺寸进行了研究。结果表明：镁合金脱氧可使钢中全氧降至13×10-6以内，且夹杂物在钢中呈细小、弥散状分布，脱氧效果优于铝脱氧。
為進一步提高鋼水潔淨度，減少夾雜物對產品性能的影響，在實驗室研究的基礎上，採用含Mg閤金包芯線在優質高碳鋼上進行瞭脫氧工藝的工業性試驗研究，併對不同脫氧工藝條件下鋼中T[O]和夾雜物組成、形貌和呎吋進行瞭研究。結果錶明：鎂閤金脫氧可使鋼中全氧降至13×10-6以內，且夾雜物在鋼中呈細小、瀰散狀分佈，脫氧效果優于鋁脫氧。

In order to improve the cleanliness of molten steel and decrease the effect to products caused by inclusions, the industrial experiments of deoxidation by Mg-alloy were carried out in quality high carbon steel which was based on the results in lab. The total oxygen, the compositions, the morphology and the size of the inclusions with different deoxidation process were investigated. The results showed that the total oxygen in molten steel deoxidizated by Mg-alloy is less than 13×10-6 and the inclusions are small and dispersive, which indicates that the effect of deoxidation by Mg-alloy is better than Al.
