Abstract:In this article, a new developmention of the quality control technology for round billets used to Petroleum pipes were concluded. By EAF short route.The quality level for round billets used to Petroleum pipes by EAF short route for(1)Pureness:[P]≤70ppm,[S]≤10ppm,[O]≤15ppm,[N]≤50ppm,[H]≤1.0ppm,[Cu]≤0.10%,[Pb]+[Sn]+[As]+[Sb]+[Bi]≤170ppm;(2)Quality of billet:Meets quality for high level Petroleum pipes;(3)Chemistry element control:[C]=±100ppm; [Al]=±100ppm; [Ca]/[S]=1.0~4.0;[Al]/[N]≥2.0.
