中文摘要 | API5L/X65是本公司新開發65Ksi級海底油氣管線用鋼,不論在安全性、防蝕 及鋼材韌性等方面均有相當高之要求,因此對鋼胚內外部品質之需求亦特別嚴格。該 產品自86年8月開始量產以後,鋼板陸續反映有超音波不合及表面起泡、剝片等煉鋼 缺陷剔退,因而採取相關之品質改善措施包括渣改質及控制鋼液鈣含量,終於有效降 低鋼板煉鋼缺陷剔退率。 |
英文摘要 | The API5L/X65 plate used in LPG marine pipe was recently developed at China Steel Corporation (CSC). This product demands a strict quality control to meet the safety, anti�鞋orrosion and toughness standards. CSC began mass production of API5L/X65 in August 1997, and some major defects such as UT disqualification, blister and sliver on plate occurred, and these defects were mostly caused by inclusions, Through a series of improvement approaches covering slag treatment in refining process, and Calcium content control in liquid steel, the reject rate of this product is significantly reduced. |
