通过西宁钢厂试生产2Cr_(13)不锈钢管的实践证明:采用轧—拔结合方法、中间管和成品管在750~770℃进行再结晶退火、用硫酸加食盐溶液去除氧化铁皮、涂以牛油石灰作润滑剂的工艺生产2Cr_(13)不锈钢管是可行的。拔制时没有出现纵裂、表面良好。经检验,成品管的内外表面、尺寸精度、机械性能等技术指标均符合 YB804—70标准的要求。
The practice of trial production of 2Cr_ (13) stainless steel tube by Xining Steel Plant proved that the recrystallization annealing was carried out at 750 ~ 770 ℃ with the combination of rolling and pulling process, the oxide scale was removed with sulfuric acid and salt solution, It is feasible to produce 2Cr_ (13) stainless steel pipe with oil lime as a lubricant. Pull system did not appear when the split, the surface is good. After testing, finished pipe surface, dimensional accuracy, mechanical properties and other technical indicators are in line with the YB804-70 standards.
