设计了一种用于铝合金薄带连铸的立式双辊铸轧机，并对其性能进行了研究。铸带厚度小于3 mm，铸带速度大于60 m/min。双辊连铸机的特点如下。使用铜辊，并且不使用润滑剂以提高铸造速度。熔体与轧辊之间的热传递通过熔体的静水压力得到改善。分离力非常小，以防止带材粘在辊上。为改善铸带组织，进行了低倍连铸。对A1050、A3004、A5083、A5182、A6063、A356等几种铝合金进行了铸轧试验。铝合金，其凝固区是非常广泛的，如A5182，可以使用本研究的双辊连铸机在高达150米/分钟的速度铸造。薄带小于3毫米。
A vertical-type twin roll caster for strip casting of aluminum alloys was devised and its properties were investigated. The strip, which was thinner than 3mm, could be cast at speeds higher than 60m/min. Features of the twin roll casters are as below. Copper rolls were used and lubricant was not used in order to increase the casting speed. Heat transfer between melt and the roll was improved by hydrostatic pressure of the melt. Separating force was very small in order to prevent sticking of the strip to the roll. Low superheat casting was carried out in order to improve microstructure of the strip. Roll casting of some kinds of aluminum alloys: A1050, A3004, A5083, A5182, A6063 and A356, were tried. Aluminum alloy, whose freezing zone is very wide like A5182, could be cast using the twin roll caster of the present study at speeds up to 150m/min. Strips were thinner than 3mm.
