現代高頻通訊、电子計算等技术的迅速发展,迫切需要尺寸精确、表面良好的合金超薄带材。生产合金超薄带材的关鍵設备为廿辊軋机。本文仅就“罗恩”(Rohn)型廿輥軋机的設备性能,軋制工艺,軋制缺陷的形成原因和消除方法,作較系統的阐述。 The rapid development of modern high-frequency communications, electronic computing and other technologies urgently needs ultra-thin strips of alloy with good dimensional accuracy and good surface. The key equipment for the production of thin strips of alloy is the 20-high mill. In this paper, only the equipment performance, rolling process, rolling causes and elimination of rolling defects of the “Rohn” type 20-roller mill are systematically described.
