熱軋沖壓橋殼用鋼板的研制開發

Development of Hot-rolled Drawn Axle-housing Steel

摘要: 通過對不同化學成分的試驗用鋼進行不同熱軋工藝、終軋溫度和卷取溫度的試驗研究,分析了化學成分、工藝參數、金相組織對橋殼鋼性能的影響:確定了化學成分及符合武鋼生產條件的工藝制度;在此基礎上研制開發了440MPa級熱軋沖壓橋殼專用鋼板.

Abstract: During the development of axle-housing steel, the composition and hot-rolling schedules have been studied and determined, the mechanics properties and formability of axle-housing steel have been tested, and the effects of composition and hot-rolling schedules on the mechanics properties and formability of axle-housing steel have been analyzed.
