Abstract
In order to solve surface upwarping during the production of 483 grade pipeline steel exported in north America by Baosteel, factors that might cause defects in continuous casting slab production, heavy plate rolling and UOE welded pipe production link were analyzed by metalloscope, scanning electron microscope and X-ray spectrometry for macroscopic and microstructure morphology and chemical composition, test scheme for typical defect location was planned, defect map was preliminarily established, and the corresponding improvement measures were summarized. The results showed that surface upwarping defect of 483 grade pipeline steel was effectively controlled, and the defect rate was significantly decreased.关键词
