Spread Formulae of Section Steel Rolling
-
摘要: 在分析了前人計算型材軋制寬展變形的各種方法之后,得出結論:現有的各種寬展模型不能滿足CAD/CAE軟件系統的需要。高精度的寬展模型必須分不同的孔型系統和軋機布置形式,由現場實驗,經統計回歸得到。用此方法,得到兩組分別適用于橫列式和復二重小型、線材軋制寬展模型。Abstract: Based on analysis of all kinds of methods that calculatal the spread of bar steel rolling,it came to the conclusion that any of them can not satisfy the needs of CAD/CAE software system. Accurate spread formulae must be studied out by experiments and regression analyses according to different roll passes and different rolling mill layout. Used this method,two groups of spread formulae are separately suitable for opentrain bar mills and doubledue wire as well as bar mills.
