摘　　要：本文阐述了大幅度提高闪速吹炼炉炉体寿命的对策。论述了炉体设计需要突破现有的思路,采用高出拱脚砖的高铜液面的设计和操作新理念,反应塔、沉淀池、上升烟道各部分采用合适的结构,沉淀池垂直铜水套内侧堆焊层采用抗冲刷和抗渣侵蚀性能更好的合金,并适当加厚,所有直接接触烟气或熔体的铜水套内侧应设计成利于挂渣的凸凹形,选择容易挂渣的铁酸钙渣型,并对铜水套漏水情况进行有效地监控,可使闪速吹炼炉炉体使用寿命由目前的4年左右大幅度地提高到8~10年以上,并可为每个公司每年创造近1590万元的利润,如果国内的闪速吹炼炉都采用该技术,则每年为国内创造7950万元的收入。In this paper,the solution of greatly improving the life of flash converting furnace is de-scribed.The design of furnace body needs to break through the existing ideas,adopt the new idea of de-sign and operation of high copper liquid level with high arch foot brick,adopt suitable structure of reac-tion shaft,settler and uptake shaft,adopt better alloy of anti-scour and anti-slag erosion resistance in the inner surfacing layer of vertical copper water jacket of settler,and thicken properly,all copper water jacket with direct contact with flue gas or melt should be designed into convex concave shape of slag hanging slag,select calcium ferrite slag type with easy slag hanging slag,and effectively monitor the leakage of copper water jacket,which can greatly increase the life of flash converting furnace from about 4 years to 8-10 years,And can create nearly 15.9 million yuan for each company every year,if the do-mestic flash converting furnace adopts this technology,it will create 79.5 million yuan of income for the country every year.
