“…A scraper has two roles. One is separation of two kinds of molten metal, and the other is to make the surface of the base strip a semisolid of high solid fraction [24][25][26][27][28][29]. Figure 21 shows two kinds of twin roll casters equipped with a scraper and a close-up of the scraper.…”

“…Figure 21 shows two kinds of twin roll casters equipped with a scraper and a close-up of the scraper. The scraper was attached to the vertical-type twin roll caster and an unequal-diameter twin roll caster, and these are shown in Figure 21a,b, respectively [24][25][26][27][28][29]. The unequal-diameter twin roll caster is suitable for a mounting a scraper because there is enough space.…”

“…In the past 20 years, the design and testing of twin roll casters to cast clad strips has been conducted at the Osaka Institute of Technology (O.I.T.) to resolve these problems [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. Two types of twin roll casters for clad strips were designed, assembled, and used to cast clad strips in an oxidizing atmosphere.…”

“…The vertical-type twin roll caster can cast three-and five-layer clad strips. The twin roll caster equipped with a scraper can cast clad strips without the bonding surface coming in contact with the oxidizing atmosphere [24][25][26][27][28][29]. The twin roll caster equipped with a scraper can cast clad strips consisting of magnesium alloy strips.…”

Production of aluminum alloy clad strips requires many processes, and a reduction in the number of processes has long been demanded. A method to cast clad strips directly from molten metal using a twin roll caster with copper rolls is proposed in this work. Two types of twin roll casters were designed and tested. One was a vertical-type tandem twin roll caster and the other was a twin roll caster equipped with a scraper. The casting of the clad strips was conducted in an oxidizing atmosphere. The clad strips were cast at speeds higher than 15 m/min. This casting speed is much higher than that of conventional twin roll casters for aluminum alloys. The roll load was smaller than 0.2 kN/mm. This small roll load means that strips were not bonded by hot rolling. The clad strips had a clear interface between strips, and elements in each strip did not diffuse into other strips. The clad strips did not fracture at the interface in a tension shear test. This means that the clad strips were strongly bonded.

Casting of clad strip consisting of Al-40%Sn-1%Cu alloy and 1050 pure aluminum from molten metals was attempted using an unequal diameter twin-roll caster equipped with a scraper. The liquidus line and solidus line of the Al-40% Sn-1% Cu alloy are 620 °C and 220 °C, respectively. The liquidus line and solidus line of the 1050 are 657 °C and 646 °C, respectively. Therefore, solidification temperatures of the two aluminum alloys are much different. When an Al-40%Sn-1%Cu solidification layer was bonded to a solidification layer of the 1050 alloy, the temperature of the 1050 solidification layer surface was higher than the solidus line of Al-40% Sn-1% Cu. However, the Al-40% Sn-1% Cu alloy could be bonded to the 1050 strip and a two-layer clad strip could be cast. The interface between the two strips was very clear. Electron Probe Microanalysis (EPMA) indicated that Sn in the Al-40% Sn-1% Cu alloy did not diffuse into the 1050 alloy. Tensile shear tests were conducted using the as cast clad strip, and no breakage occurred at the interface between the strips but only in the Al-40% Sn-1% Cu layer. This result confirmed that the two strips were strongly bonded at the interface.
