铝熔炼炉炉衬组合的优化模拟
Numerical simulation and optimizing combination of aluminum melting furnace linings
摘要
Abstract
In order to reduce heat loss and save cost, three-tier slab was simplified for furnace linings of widely-used reverberatory aluminum melting furnace in aluminum casting industry. Heat transfer analysis of different heat-insulating mode on furnace lining was carried out. Based on economic thickness method, the calculation formulae of economic thickness for furnace linings were introduced, and furnace linings were optimized by computer programming. On this basis, a three dimensional mathematical mode! of aluminum melting furnace was developed based on heat balance test of regenerative aluminum melting furnace. Furnace linings before and after optimization with 40-week working system were simulated by CFD software FLUENT. The results show that ideal economic effect is obtained by optimization as follows: furnace side with 40 mm clay castables, 300 mm diatomite brick and 120 mm alumino-silicate fiber felts; furnace top with 220 mm refractory concrete, 150 mm clay castables and 80 mm alumino-silicate fiber felts; furnace bottom with 200 mm isigh-atamina castabte, 300 mm diatomite brick and 50 ram clay castables.关键词
