| In this paper, the smelting technologies of Lead and Zinc and their substantial development are analyzed and summarized, the development of I.S.P technique which is used in blast agglomeration, lead cooling, energy conservation, valuable element recycling, automata, admeasure sequence, transportation of cold coke and environmental protection is introduced here. The demonstration integrates the design and practice in II system of Shaoguan Smelter.I.S.P is the typical complex and continuous production process. Based on the peculiarity of I.S.P: physical chemistry reaction is quite complex, operation condition is comparatively rigid, the charging ration needs to be exactitude. Temperature variety of zones in furnace including: warm-up charging zone, re-oxidation zone, revivification zone, slag smelting zone,The soft point and soft zone are the key factors, which have an effect on the smelting of ISP and it is a comprehensive parameter appraising the quality of sintered aggregate. The anti-soften ability of aggregates may be investigated by it at the high temperature. The output of crude zinc is closely related to output capacity and efficiency. Based on the above analysis and summarization, combined with inner factors of ISP, manyinformation is collected and processed, and soft point of aggregate and crude zinc output of ISP are chosen, and the related models are established:1) Relationship model of soft point and component of sintered aggregates:T3 = 1574.2-5.1*S%+95.9*CaO/SiO2+3.3*Fe/SiO2-35.1* Pb%2) Output model of crude zinc products by ISF process: WZn=-1.720+2.739*V-3.362*Km+0.417*T3-2.669*AsThe related striking is R=0.87, which is higher than 0.7, and this shows that the equation is striking. And the practice result shows they are very effective to control and monitor the production. |
