针对高硫锰矿块状物(10~40 mm),3家合作在玛瑙山矿采用GTO脱硫为剂在1.26 m3试验炉进行了半工业脱硫试验。结果表明,脱硫效果明显,矿石残存硫量为0.98%,GTO脱硫率67.66%,达到了高炉冶炼富锰渣的入炉要求。
For the high-sulfur manganese lumps (10-40 mm), three companies conducted a semi-industrial desulfurization test in a 1.26 m3 test furnace using GTO desulfurization agent at the Agate Mine. The results show that the effect of desulfurization is obvious. The residual sulfur content of ore is 0.98% and the desulfurization rate of GTO is 67.66%, which meets the requirement of blast furnace smelting manganese-rich slag.
