[JiuJu Magnet Industry News] Recognized by the authority again! Rare earth permanent magnet program among the Ministry of Industry and Information Technology 2025 "unveil the list of commanders" list

End-to-End Solution for Magnetization Automation

近日,工業和信息化部公示 2025 年度智能制造系統解決方案 “揭榜掛帥” 項目名單。由包頭市上承工程技術有限公司與包頭天和磁材科技股份有限公司聯合申報的 “稀土永磁新材料工藝智能設計與優化控制解決方案” 成功登榜。值得一提的是,自 2023 年此項 “揭榜掛帥” 工作啟動以來,該方案是內蒙古自治區范圍內唯一入選的項目,這一成果標志著包頭市在稀土永磁材料智能制造領域的技術實力,已獲得國家級層面的權威認可。

稀土永磁材料是高端裝備制造、新能源汽車、航空航天等戰略性新興產業不可或缺的核心基礎材料,其生產工藝的智能化轉型升級,是推動相關產業實現高質量發展的關鍵支撐。此次成功入選的解決方案,直擊傳統稀土永磁材料研發與生產環節的技術瓶頸與行業痛點,搭建起一套貫穿微觀配方設計至宏觀工藝調控的全流程智能管控體系。
該體系深度整合多尺度計算、機理建模與數據驅動技術,實現了兩項核心技術突破:其一,創新實現材料配方的逆向智能生成,擺脫傳統研發模式對經驗積累的過度依賴,無需反復開展試錯實驗即可精準定位最優配方;其二,攻克關鍵冶煉工序的精準閉環控制難題,保障生產全流程的穩定性與可控性,從根本上扭轉傳統模式下研發周期冗長、生產過程波動較大的行業痛點。
方案落地后,將為相關企業帶來研發創新與生產管控雙重維度的顯著效益。在研發創新領域,依托系統的逆向設計與多尺度建模能力,新產品配方的研發周期將大幅縮減 —— 從傳統模式的 3-6 個月壓縮至 2-4 周,縮短幅度超 50%;同時研發試錯成本降低 30% 以上,助力企業顯著提升創新效率與核心競爭力。

undefined

在生產管控維度,系統憑借配方設計與熔煉工藝的協同優化能力,可有效減少稀土原料燒損,顯著提升產品性能一致性。據測算,方案落地后,產品關鍵磁性能的批次間波動幅度將收窄 20% 以上,配方設計效率提升約 50%,產品綜合合格率也將提高 3-5 個百分點,為企業實現降本增效目標、增強產品市場競爭力筑牢堅實基礎。
此次項目成功入選,不僅充分彰顯了包頭市在稀土產業智能制造領域的領先技術優勢,更能為內蒙古自治區稀土產業的轉型升級,提供一套具備復制價值與推廣前景的智能化實踐方案。展望未來,隨著該方案的逐步落地與規?;茝V,將進一步助推我國稀土永磁新材料產業的智能化升級進程,為高端裝備制造業產業鏈供應鏈的自主可控與高質量發展注入強勁動力。
