螺旋方铜管风口采用10kg/cm~2左右高压水强化冷却,已在包钢高炉上获得推广使用,其平均工作寿命比空腔式结构的铸铜风口高七倍,但还存在着破损后往炉缸内漏水等问题。为解决这些问题,设计了几种特殊结构的螺旋管风口,其平均工作寿命在原有基础上又提高1～3倍(为70～100天)。本文将简介这种风口冷却参数和传热能力的设计计算。
The spiral copper tube tuyere is strengthened with high pressure water of about 10kg / cm ~ 2 and has been widely used in the blast furnace of Baotou Iron and Steel Co., Ltd. The average working life is seven times higher than that of the bronze tuyere of the cavity structure. However, Leakage to the hearth and other issues. In order to solve these problems, several specially designed helical tuyeres have been designed and the average working life of them has been increased 1-3 times (70-100 days) on the original basis. This article will outline the design and calculation of the tuyere cooling parameters and heat transfer capabilities.
