为了满足我国高炉对铜冷却壁的需求,结合铸铜冷却壁热态试验数据、采用数值模拟的方法优化设计出一种价格更低的轻型长寿铜冷却壁。新设计的冷却壁改变了以往的冷却壁设计理念,将冷却通道放置在肋与壁体之间,通道、肋、镶砖平行,整个冷却壁在高炉内水平放置。冷却壁厚度95 mm,比普通铜冷却壁薄,导致高炉内有效使用容积增加,而铜冷却壁费用降低30%。为推广和开发新型铜冷却壁提供了可靠的理论依据。
In order to meet the requirement of blast furnace for copper stave in China, combined with the thermal test data of cast-iron stave, a light and long-life copper stave with lower cost was optimized by numerical simulation. The new design of the cooling wall changes the design concept of the previous cooling wall, the cooling channel is placed between the ribs and the wall, the channel, ribs, mosaic tile parallel, the entire cooling wall in the blast furnace placed horizontally. The thickness of the stave is 95 mm, which is thinner than the normal copper stave, resulting in an increase in the effective volume used in the blast furnace, while the cost of the stave is reduced by 30%. It provides a reliable theoretical basis for the promotion and development of a new type of copper stave.
