【摘要】 通过对80钢盘条脆断断口形貌观察和金相组织分析,认为盘条表面损伤部位的金属基体产生塑性变形和位错增加是拉拔断丝的主要原因,在高碳钢生产及吊装运输中应采取措施避免盘条擦伤,以提高产品质量。更多还原

【Abstract】 It is pointed out by the brittle fracture appearance observation of 80 steel wire rod and microstructure analysis that the plastic distortion of basal metal and dislocation adding at surface damage position are the main cause of wire drawing breaking. In order to improve products quality, the measurement avoiding wire rod scratching should be taken in the course of high carbon steel production, hoisting and transportation.更多还原
