我国高碱度钒钛烧结矿低温还原粉化(RDI)严重。本文就如何改善高碱度烧结矿RDI进行了探讨并指出:当MgO含量提高到3.5%~4.5%时,RDI可降低约20%;用CaCl_2稀溶液浸润高碱度钒钛烧结矿,其RDI可降低28%~30%。
China’s high alkalinity vanadium titanium sinter low temperature reduction powder (RDI) serious. This paper discusses how to improve the RDI of high basicity sinter and points out that when the content of MgO is increased from 3.5% to 4.5%, the RDI can be reduced by about 20%. The RDI Can be reduced by 28% to 30%.
