中文摘要 | 中鋼公司為提昇冷軋中碳鋼市場佔有率,自民國91年起全力開發冷軋中碳鋼產品。首先開發數種彈性生產製程,突破薄板生產瓶頸。其次,以調質軋延或冷軋加工硬化調整產品硬度,成功擴大產品之供料尺寸及硬度範圍。表面粗糙度水準可滿足最嚴格的電鍍需求。在產品開發過程中,除了考慮冶金及機械性質外,進一步簡化生產流程及並依產線特性分工,以達到生產流程最短、品質最穩定,產率及合格率最高之目標。民國93年成功的開發出S35CM、S45CM及S50CM三鋼種,厚度0.30~2.50mm,寬度850~1,000mm,粗糙度Code 20/25/35及各種硬度等級之冷軋中碳鋼產品,因產品種類齊全且品質優良,訂單量從民國91年第一季三千噸增加到民國94年第一季1萬5千噸以上,市佔率大幅提升。 |
英文摘要 | CSC has developed cold rolled medium carbon steel since 2002 to enhance market share in cold rolled medium carbon steel. The first break-through was the development of several flexible manufacturing process for thin gauge manufacturing. After that, the product hardness was fine tuned by temper rolling or work hardening by cold rolling. The manufacturing capability in variety of product size and hardness was successfully enhanced, and the surface roughness can also satisfy the highest requirement of plating quality during the development, besides considering metallurgical and mechanical characteristics, process flow was also simplified. The shortest process and most stable quality characteristics, resulting in the best performance both in yield and OK yield. S35CM, S45CM, and S50CM steels were brought to the market in 2004, the thickness varies from 0.3mm to 2.5mm, width is between 850mm and 1,000mm, roughness code 20/25/35, and also various hardness grades of cold rolled medium carbon steel. The P.O. received went up from 3,000 tons for 2002Q1 to more than 15,000 tons for 2005Q1 due to the advantage of complete product lines and high quality. The market share was highly enhanced. |
