矿热炉炉衬的发展趋势 —矿热炉炉衬改造理论分析 白万立 王利民 摘要 [1]随着时间的推移，优质矿产资源日益减少，加上环境保护意识的增强，有效利用劣矿产资源，降本成为铁合金生产商不断追求的目标，矿热炉生产技术的发展主要就是围绕这条主线展开的提高热效率，提高生产率集中冶炼研制成世界上最大的密闭式矩形高锰合金炉；并试制成功容量矩形矿热炉，以及开发出熔炼硅锰合金的2MVA等离子竖式炉。在大型炉子的设计中，全部利用计算机的最佳数学模型来计算确定大型矿热炉的最佳参数和最佳工作状态。]河南方圆碳素集团有限公司对矿热炉炉衬技术的研究，不仅单纯的追求材质方面的改进而且结合电路炉衬结构采取强制冷却措施，以延长炉衬寿命。国外的主流热压炭砖-?SLTD技术也逐渐在国内打开了市场。还有针对矿热炉炉壁冷却的各种技术也在不断试验研究之中。 延长矿热炉炉衬使用寿命除了炉壁的冷却程度外，还需科学管理、规范操作、，选择优质的耐火材料，优良的施工质量。新技术、新材料的开发，为实现冶炼重金属矿热炉整体寿命的提高提供了可能。 关键词 矿热炉、冷却技术、炉衬使用寿命 Summary Over time, high-quality mineral resources dwindling, coupled with awareness of environmental protection, efficient use of inferior mineral resources, energy saving and cost reduction and increased profits become ferroalloy manufacturers continue to pursue the goal, submerged arc furnace production technology mainly focus on the development of the main line expanded. Submerged arc furnace large-scale, control automation, precision fine-tuning to improve the smelting intensity, improve thermal efficiency, increase productivity, focus smelting, which is the main direction of the future development of the submerged arc furnace. At present, Russia developed into the worlds largest enclosed rectangular high manganese alloy furnace; and successful trial giant rectangular submerged arc furnace capacity, as well as the development of silico-manganese alloy smelting 2MVA plasma shaft furnace. In large furnace designs, all of the best mathematical model using a computer to calculate and determine the optimum parameters of large submerged arc furnace and the best working condition. To do domestic work carbonaceous material layer submerged arc furnace method widely used in insulation lining structure. Since arc furnace slag lining in high temperature conditions and finished fluid mechanical erosion and chemical attack. Regardless of the high quality refractory lining are inevitable damage, damage to the speed of its parts are inconsistent, the lower part of the furnace wall, bottom center of
