摘 要：对SUS304不锈钢抛光"点状"缺陷解析表明,缺陷主要是由于Al2O3等脆性夹杂物在抛光处理后部分脱落而形成。控制钢水T[Al]、提高AOD炉渣还原性能、喂SiCaBa线处理等夹杂物控制技术,实现了板坯总[O]从45.1μg/g下降为30.7μg/g,而且夹杂物变性,改善了表面抛光"点状"缺陷。
Abstract: The spot defect on the polished SUS304 stainless steel was analyzed,the defect was mainly induced by the brittle Al2O3 inclusions that fell off during polishing.Some inclusion control technologies were adopted as the countermeasures,such as T[Al] controlling,improvement on the reduction property of AOD slag and SiCaBa wire feeding.Therefore,the T[O] decreased from 45.1 μg/g to 30.7 μg/g,the inclusions were modified and the spot defect was improved.
