中文摘要 | 棒線產品因市場要求日益嚴苛,進而朝高品質、多樣化產品發展,同時為確保具競爭力,由煉鋼、連鑄、熱間軋延,到精整作業一連串可以削減成本,提升生產力之技術,以及滿足客戶需求的新產品,被陸續研究開發出來。 近來條線生產技術的發展,朝向提升鑄胚(軋延素材)品質以及引進新軋延技術。前者包括:高清淨度鋼吹煉技術、改善中心偏析、減少表面缺陷等。後者主要有:粗軋的平輥(groove-less)軋延、精密整徑軋延(Sizing Mill)、無尺寸限制軋延(Freesizing mill)等。另外,將控制軋延、控制冷卻技術結合應用於材質改造,也使省二次加工製程、提升加工性等多樣新產品得以發展出來。精整製程方面則藉由引進自動化、連續化設備,降低依賴人工作業,大幅提升效率。 |
英文摘要 | Bar and wire rods develop to high quality and diversified application in catering to strignet requirements of market. New technology for cost reduction and productivity upgrading as well as new products of customer satification in the processes of steelmaking, continuous casting, hot rolling and finishing have been developed. The development of the steelmaking and continuous casting involve high purity, high cleanliness refining technologies, center segregation minimization and surface qualities improvements. Meanwhile, groove-less mills, sizing mills and freesizing mills have also been introduced to the new hot rolling process. To incorporate process characteristics of controlled rolling and controlled cooling, materials with new structures and properties have been developed. These new materials benefit downstream for lower cost and better workability. Furthermore the concept of automation and continuous equipment provides fast, efficient and reliable finishing process. |
