摘要

Y309乃高品級不銹鋼銲條之心線，為取代昂貴的進口品，長久以來，該高合金鋼材已成為國內不銹鋼條線業者開發之重點產品。本研究針對Y309不銹鋼熱軋生產之技術問題，模擬其熱軋條件，探討此材料之熱加工性，鑽研材料微觀組織與加熱時間對其熱加工性質之影響，同時設計特定參數探討酸洗除銹之最佳條件，進而獲知此高合金鋼材料之適當生產條件。此項研究也驗證Y309不銹鋼高溫機械性質理論，並在不銹鋼線生產工廠得到大量生產印證，將良品率提升至97%，每小時產量亦自5噸提升至20噸，成功地開發此項高附加價值之新產品。

Y309 stainless steel with high Cr and Ni contents is becoming more important for use as core material for welding wires. Because of the high value, a lot of domestic steel manufacturers are interested in its production in Taiwan to replace imported goods. This study is aimed at solving the technical problems of its production and simulate the hot rolling conditions to investigate the hot workability at different temperatures. The microstructure of Y309 under different hot rolling conditions was studied systematically. Also the pickling conditions were researched in this study. The optimal parameters for the production of this material were found out after a series of experiments in the laboratory. These technical parameters were carried out in manufacturing plant and proved optimally. The yield rate achieved more than 97% and productivity was improved from 5 up to 20 tons per hour.
