Li_2O对低氧化性钢包渣改性处理的实验研究

Experimental Study on Modifying Treatment of Low-Oxidability Ladle Slags by Addition of Li_2O

通过模拟低氧化性钢包渣组成 ,采用CaO -SiO2 -Fe2 O3-MnO2 (2 % ) -MgO(6 % ) -P2 O5(3 % )系熔剂 ,在CaO/SiO2 ≤ 2 .5 ,Fe2 O3≤ 5 %的范围内 ,用Li2 O替代熔剂中CaO ,测定Li2

By simulating the composition of low oxidability ladle slags, using CaO-SiO 2-Fe 2O 3-MnO 2-MgO-P 2O 3-base flux and substituting CaO with Li 2O, the effects of Li 2O on the melting point of the flux and the rephosphorization of molten steel controlled by flux have been studied in the range of CaO/SiO 2≤2.5 and Fe 2O 3≥5%.
