內容簡介

隨著材料信息技術的發展和材料基因工程提出，模擬模擬技術開始在研發過程中得到越來越廣泛的應用。相對於傳統研發模式的「實驗試錯」，通過模擬模擬計算實現快速、低成本的「數字試錯」，對研發效率的提升作用越來越顯著。數字化工藝模擬模型及平台逐漸成為了鋼鐵產品研發不可或缺的重要工具。本書通過對熱軋產品生產從加熱、軋制到冷卻各工序的工藝過程及微觀組織演變的數字化模擬建模方法研究，以及對全流程模擬模型的集成技術及模擬平台設計方法的探討，充實和形成熱軋產品生產工藝的數字化模擬理論及應用技術，為輔助熱軋產品的數字化研發、生產工藝優化、模擬平台建設提供技術支撐。 本書可供相關企業、研究院工程技術人員參考，也可供高等院校材料成形專業師生參考。
