摘要
介绍了天津市无缝钢管厂运用锻造热处理工艺理论及工艺模拟试验,在现有的热轧管生产线上实施在线内外喷水淬火和离线回火的调质工艺生产N80钢级光套管的情况。生产实践证明,在大生产模式的条件下实施该调质工艺,钢管的综合力学性能稳定,达到了预期效果。该工艺也是一种节能增效的工艺。
Described is the heat treatment of the N80 black casing by means of the on-line internal-external water spray quenching process and the off-line temper process on the hot rolling production line in Tianjin Municipal Seamless Steel Tube Plant based on the application of the forging heat treatment process theory and the relevant process simulation tests. The operation practice proves the quenching and tempering process is capable of ensuring the consistence of the overall mechanical properties thus meeting the expected targets in the massive production of the N80 casings. Moreover the said heat treatment process is also an energy saving one.
