查询词典 slag-tap furnace

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。

The results show that magnesium and aluminum theoretically can be thoroughly dissolved from the blast furnace slag by diluted sulfuric acid pretreatment on the blast furnace slag even if the ended concentration of sulfuric acid is 0.001mol/L, while the titanium basically could not be dissolved. Therefore it is theoretically indicated that the separation of the magnesium and aluminum from the slag with the least titanium loss by diluted sulfuric acid pretreatment is possible.

结果表明，采用稀硫酸对高炉渣进行预处理，当终酸浓度即使为0.001mol·l~(-1)时，镁、铝理论上也能全部被酸浸出，而钛在0.001 mol·l~(-1)的酸浓度条件下基本不被浸出，从而从理论上可以说明对高炉渣采用稀酸预处理可以很好的将炉渣中的镁、铝等杂质分离出来，而钛极少被浸出。
