In this paper, the solution of greatly improving the life of flash converting furnace is described. The design of furnace body needs to break through the existing ideas, adopt the new idea of design and operation of high copper liquid level with high arch foot brick, adopt suitable structure of reaction 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 domestic flash converting furnace adopts this technology, it will create 79.5 million yuan of income for the country every year.
