摘要

15NiCuMoNb5-6-4钢(%:0.14C、1.14Ni、0.62Cu、0.32Mo、0.020Nb)用100 t EAF+LF+VD-铸锭工艺冶炼

锻成Φ350 mm管坯

然后用Φ460 mm PQF轧机轧成Φ323.9 mm×14.2 mm的钢管。该钢管的冶金质量、力学性能、脆性转变温度、高温持久强度等均符合标准要求。

Abstract

The 15NiCuMoNb5-64 steel (%:0. 14C

1. 14Ni

0.62Cu

0.32Mo

0.020Nb) is melted by 100 t EAF+LF+VD-Ingot casting process

forged to Φ φ350 mm tube blank and hot-rolled to Φ 323.9 mm×14.2 mm steel tube by Φ460 mm PQF steel mill. The metallurgical quality

mechanical properties

brittle transformation temperature and stress- fracture strength of the steel tube at high temperature endure and so on all meet the requirement of standard.
