一、提高鼓风炉熔解量的必要措施(一)保持炉况正常:欲提高鼓风炉的熔解量,首先要保持操作的正常,(?)除作业中的故障,主要的故障有三方面:1.炉缸产生底块,虹吸口不出铅:炉缸中铅液之上、炉渣之下生成结壳(不产冰铜),致铅不八虹吸口流出而与渣一起自渣口流出,不仅升高了渣含铅量,同时大大降低了粗铅的质量,严重地影响正常生产。(1)原因:①焦率过高:焦率为24％～22％,因还原性太强,将砷、锑、铁等杂质还原生成大量黄渣,温度稍低即行凝结;

First, to improve the blast furnace melting amount of the necessary measures (A) to maintain normal furnace conditions: To improve the melting furnace blast furnace, the first to maintain the normal operation, (?) In addition to the operation of the fault, the main fault has three aspects: Resulting in a bottom block, the siphon mouth no lead: lead liquid in the hearth above the slag generated crust (not produce ice copper), lead to non-siphon outlet outflow and residue together with slag flow out, not only increased The slag lead content, while greatly reducing the quality of crude lead, seriously affecting the normal production. (1) Reasons: (1) Coke rate is too high: the coke rate is 24% ~ 22%. Due to too strong reducibility, impurities such as arsenic, antimony and iron will be reduced to form a large amount of yellow residue,
