By investigating the construction status andexisting problems of Zhaoba Village in Nanjing, it tries to take “beauty” and “livability” as the planningrequirements. The village positioning is planned accurately, and the functional layout is carried outreasonably.

文摘为深入研究转炉渣气化脱磷后循环利用的工艺效果,在承钢公司100 t转炉上采用焦粉进行气化脱磷试验并分析了焦粉还原P的可行性.试验结果表明:在溅渣护炉阶段添加焦粉进行气化脱磷,熔渣中先被还原的是P2O5,试验炉次平均气化脱磷率为36.78%;应用气化脱磷渣循环利用工艺后,试验炉次冶炼终点钢液成分合格,钢液中P质量分数呈现降低趋势;试验中吨钢的钢铁料消耗量平均降低0.04 kg,吨钢的石灰消耗量平均降低5.54 kg,吨钢的CO_(2)排放量降低约1 kg.
