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.

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。
