双辊铸轧技术可直接将液态金属生产成板材,而不需要额外的热轧或冷轧设备。资金投入少,生产成本低,使其成为生产金属板材的一种优良工艺。双辊铸轧工艺不仅可以直接生产轻合金薄带,而且可以有效地生产高强度箔材和轻合金复合带材。近年来,随着铸轧设备不断改进,多种铝合金和不能采用铸造工艺浇注的镁合金已可以通过现代双辊铸轧设备进行生产,并且微观组织得到了改善。双辊铸轧技术生产轻金属带材,一个重大优势就是可以获得非常细小的晶粒组织。细小晶粒组织可使合金具有良好的机械性能和成形性。本文将讨论铸轧板材的超塑性。
Twin roll casting technology produces liquid metal directly into sheets without the need for additional hot or cold rolling equipment. Less capital investment, low production costs, making it an excellent production of sheet metal technology. The twin-roll casting process not only produces light alloy ribbons directly, but also efficiently produces high-strength foil and light alloy composite strip. In recent years, with the continuous improvement of the casting equipment, a variety of aluminum alloys and magnesium alloys that can not be cast using the casting process have been produced by modern twin roll casting equipment and the microstructure has been improved. Twin roll casting technology to produce light metal strip, a major advantage is that you can get very small grain size. Fine grain structure can make the alloy have good mechanical properties and formability. This article will discuss casting superplastic sheet.
