| 中文摘要 | 冷軋高碳鋼一般指碳含量大於0.50%的鋼種,為刀具類、彈簧類、華司及耐磨零件等機械五金零的原料,為值得開發供應的高附加價值產品。中鋼公司於民國92年已開發至SAE1060,如欲往更高碳的鋼種開發,考量煉鋼、熱軋、冷軋的生產困難度,及上的數量與品質需求後,首先鎖定碳含量0.55~0.76%的相關鋼種,整合成ASTM A684-1065 MOD(碳含量□0.65%)為優先開發對象,SK5M和SAE1085等碳含量□0.85%的鋼種,例為第二階段開發的考量。深入瞭解用戶的加工製程及成品品質特性需求後,熱處理性、成形性、電鍍後的光澤度及厚度的均一性等為用戶的品質要求重點,經採品質機能展開的手法,設定鋼料的化學成份、硬度、球化率、表面組糙度、內容品質及平坦度、厚度精度等開發目標值,期使新產品的試用推廣順利,用戶的需求並可得到相當程度的滿足。 |
| 英文摘要 | Cold-Rolled High Carbon Steel, with carbon content>0.50%, is mainly used in cutting tools, elastic parts, washers and wear-resistant parts. This product is worth to be developed due to its high-value-added at down stream industry. CSC had developed SAE 1060([C]□0.60%)till 2003. To develop the higher carbon content product, after surveying the process limitation of steel-making, hot-rolling and cold-rolling, and market demands, we endeavor to produce ASTM A684-1065 MOD which covers carbon content 0.55~0.76% as first stage, then followed by SK5M ([C]□0.85%). After through studying the users’ processing, and application and the quality demands, we grasp that heat treatment, cold-forming, electro-plating, flatness and thickness precision are the major concerns. By using the quality8 function deployment, we conclude chemical composition, hardness, spheroidization rate, sheet surface roughness, internal quality, flatness, thickness uniformity as the key uqality criteria for the trial manufacture. We anticipate that the new products will be promoted smoothly and its quality will fulfill our customers through such adequate methodology. |
