我厂广大职工,认真贯彻党的十一大路线,以“镁”带“钙”、“镁钙”并举,提高烧结矿的三元碱度,以100%的白云石粉代替石灰石作熔剂,生产出较高的三元碱度烧结矿。MgO含量由基准期的3.02%提高到6.61%,三元碱度(CaO+MgO/SiO_2)从1.29提高到1.54。通过高炉冶炼实践证明,提高了烧结矿的还原性,并使熔剂单耗有了大幅度下降,焦比也有些降低。且由于高炉中氧化镁含量增加,改善造渣过程,使高炉顺 I plant a wide range of workers and workers, conscientiously implement the party’s 11 major routes to “magnesium” with “calcium” and “magnesium calcium” simultaneously to improve the sinter of ternary alkalinity, with 100% dolomite instead of limestone as flux, production A higher ternary alkalinity sinter. The content of MgO increased from 3.02% to 6.61% during the reference period, and the ternary basicity (CaO + MgO / SiO_2) increased from 1.29 to 1.54. Through blast furnace smelting practice has proved that reducing the sinter, and flux unit consumption has dropped significantly, the coke ratio is also somewhat reduced. And because of the magnesia content in the blast furnace to improve the slag making process, so that the blast order
