| Abstract: | Based on the systematical research of the Nb microalloying technology ,Zhujiang steel has successfully developed 9.50mm thickness X60 pipeline steel in EAF-CSP process by Nb-Ti microalloying technology with 60mm thickness slab.The results show that the mixed grain problem of Nb microalloyed X60 pipeline steel has been solved in EAF-CSP process through the reasonable metallurgy composition design,and the control of continuous casting,soaking,descaling,controlled rolling and controlled cooling process.The steel developed is with fine and uniformity microstructure,11.5-12.0 grade ferrite grain,outstanding strength and toughness proformance,and good welding proformance. |
