在生产无缝钢管时,钢管经自动轧管机轧制之后,用水和压缩空气同时喷射其内表面,以这种雾状流体,把钢管内表面的温度降至900～1000℃,再进行均整。这就是无缝钢管生产时防止麻点缺陷的方法。
In the production of seamless steel pipe, the steel pipe by the automatic rolling mill, water and compressed air simultaneously spray its inner surface, with this mist-like fluid, the inner surface of the steel pipe temperature dropped to 900 ~ 1000 ℃, and then the whole . This is the method of preventing pitting defects in the production of seamless steel tubes.
