目前,在小型或线材轧钢厂中,为了提高钢材质量,常常在轧后采用一些急速冷却的水冷热处理装置。实践证明,使用一种多节的湍流管取得了较好的效果,在国内外已被广泛使用。为了了解这种湍流管的冷却机理,确定它的合理参数,因此在实验室中进 At present, in the small or wire rolling mills, some rapidly cooled water-cooled heat treatment units are often used after rolling to improve the quality of the steel. Practice has proved that the use of a multi-section turbulent tube achieved good results, has been widely used at home and abroad. In order to understand the cooling mechanism of this turbulent tube, to determine its reasonable parameters, so in the laboratory
