The preventive measures for the harmful defects of alkali metals are as follows: 1, reducing the alkali metals content in the raw materials; 2, increasing the MgO content of the sinter , decreasing the basicity of slag , decreasing the Si content of the pig iron, increasing relative slag volume; 3 , introducing prereduced ore pellets or partly reducted sinter; 4increasing the ability of coke resisting alkali metals; 5, using refractories that have the ability of resisting corrasion of alkali metals; 6 , cleaning the blast furnace periodically. The above recommendations are necessary for decreasing the circulation and accumulation of alkali metals effectively in blast furnace, reducing the harmful influence of alkali metals on blast furnace, increasing the smelting intensity, decreasing the coke rate, improving the gas permeability.

基于碱金属对高炉冶炼的上述危害，本文结合湘钢高炉的实际生产情况，通过理论分析、计算以及其他钢厂防治碱害的经验，提出防治高炉碱害的措施：1、减少入炉原、燃料的碱金属含量；2、提高烧结矿中的MgO含量、降低炉渣碱度、降低生铁含硅量、适当增加渣量；3、采用预还原的金属化球团或部分还原的烧结矿；4、提高焦炭的抗碱能力；5采用抗碱侵蚀的耐火材料；6、周期性性洗炉，以有效地减少碱金属在高炉内的循环富集，降低碱金属对高炉的危害，提高高炉的冶炼强度，降低焦比，改善高炉透气性。
