1、东北大学硕士学位论文炭阳极生产工艺优化的研究姓名：杨国俊申请学位级别：硕士专业：冶金工程指导教师：姚广春20030701东北大学硕士学位论文摘要对环式焙烧炉进行了结构优化，加宽了火道，缩窄了装料箱的结构尺寸，用圆形金属外壳的连通火道代替长方形耐火砖连通火道，减小了烟气在火道内的流通阻力，降低了连通火道内的蓄热，增加了装料箱内的传热效果。引进瑞士公司的燃烧控制系统。通过炉型优化和燃烧自控技术的应用，火道及料箱内的温度分布得更加均匀，提高了炭阳极质量，降低了能耗。采用改进的干法净化系统，并结合先进的火道燃烧技术，焙烧烟气中的有害物质，如焦油、氟化物、粉尘、硫等含量大幅度降低，达到国家《工业炉窖大

2、气污染物排放标准》(GB9078--1966)。对南山铝业二期炭素厂炭阳极生产工艺优化的研究结果表明，采用先进的技术装备，进行合理的工艺控制，能够生产优质炭阳极，生产效率高，能耗低，并且使排放的气体符合国家环保要求。关键词：炭阳极、焦碳煅烧、配料、混捏、成型、焙烧、烟气净化查韭查兰堕主堂堡堕查．一一!堕!!!!!ResearchontheoptimizationofcarbonanoaeproductionProcessAbstractFollowingthedurativeandrapiddevelopmentofnationaleconomy，aluminiummetaliSusedin
