Firstly, the distortion of rolled piece and the designing method in the beforehand slit pass and slit pass has been analyzed. secondly, based on the research production of predecessor and research of the author, card system selected some corresponding experience formulas such as roll force, roll moment, roll temperature and roll consume, and established spread model in the beforehand slit pass and slit pass and the distribution model of elongation coefficient. subsequently, card system applied the dynamic programming method with minimum roll consume and optimized its pass system
本文以圓鋼雙線切分為基本實體模型，著重分析了預切分孔型和切分孔型在軋制過程中的變形特點及相應的孔型設計方法；基於前人的研究成果及作者的探索，選擇了相應的軋制力、軋制力矩、溫度及能耗模型，建立了預切分和切分的寬展及延伸系數的分配模型；應用動態規劃法以能耗最小為目標函數對孔型系統進行了優化設計；利用visualbasic6 . 0和microsoftaccess數據庫的連接，建立了數據查詢系統，以visualbasic6 . 0和autocad之間的介面在vb環境下完成了斷面孔型圖的繪制。
