在高铬的钒钛磁铁矿的凝块的 MgO 流动的优化使用通过泉华和小团实验系统地被调查。MgO 在菱镁矿形式被增加。当在泉华的 MgO 的内容从 1.95wt% 被增加到 2.63wt% 时,低温度的减小降级索引从 80.57% ~ 82.71% 增加了。当在小团的 MgO 的内容从 1.14wt% 被增加到 2.40wt% 时,减小胀大的索引从 15.2% ~ 8.6% 减少了;然而,氧化小团的压缩力量戏剧性地减少了,它是有 1.14wt% 的一个 MgO 内容的 1985 N。这压缩力量不为强风炉子生产满足要求。当所有上述的结果被考虑时,有与一个低 MgO 内容匹配小团的高 MgO 内容 2.63wt% 的泉华不到 1.14wt% 是为在强风炉子熔炼高铬的钒钛磁铁矿的合理负担结构。
The optimized use of MgO flux in the agglomeration of high-chromium vanadium-titanium magnetite was investigated system- atically through sinter and pellet experiments. MgO was added in the form of magnesite. When the content of MgO in the sinter was in- creased from 1.95wt% to 2.63wt%, the low-temperature reduction degradation index increased from 80.57% to 82.71%. When the content of MgO in the pellet was increased from 1.14wt% to 2.40wt%, the reduction swelling index decreased from 15.2% to 8.6%; however, the com- pressive strength of the oxidized pellet decreased dramatically and it was 1985 N with an MgO content of 1.14wt%. This compressive strength does not satisfy the requirements for blast-furnace production. When all of the aforementioned results were taken into account, the sinter with a high MgO content (2.63wt%) matching the pellet with a low MgO content (less than 1.14wt%) was the rational burden structure for smelting high-chromium vanadium-titanium magnetite in blast furnaces.
