设计了一台熔体牵引双辊铸轧机（MDTRC），以30 m/min以上的铸轧速度铸轧铝合金薄带，并将A3003合金、A5182合金、Al-6mass%Si合金和Al-12mass%Si合金铸轧成薄带。这些合金可以在60 m/min的速度下浇铸成薄带，薄带厚度为1- 3 mm。与传统的双辊连铸机相比，MDTRC可以铸出更薄的铝合金带材。不使用润滑剂来防止带材的粘附，因为由于铜辊的作用和低分离力而不发生粘附。研究了采用MDTRC铸轧的薄带的力学性能和显微组织。结果表明，MDTRC在铝合金薄带高速铸轧中是有效的。
A melt drag twin roll caster (MDTRC) was devised in order to cast aluminum alloy strips at a speed higher than 30m/min. A3003 alloy, A5182 alloy, Al–6mass%Si alloy and Al–12mass%Si alloy were cast into thin strips using the MDTRC. These alloys could be cast into strips at a speed of up to 60m/min. The thickness of the strips was about 1–3mm. The MDTRC could cast thinner strips than the conventional twin roll caster for aluminum alloys. Lubricant was not used to prevent the sticking of the strip, as sticking did not occur due to the effect of the copper rolls and the low separating force. The mechanical properties and the microstructures of the strips that were cast using the MDTRC, were investigated in the present study. It was shown that MDTRC was useful for the high speed roll casting of aluminum alloy strips.
