A conventional twin-roll caster usually casts strips at a speed slower than 2 m/min and a roll load greater than 2 kN/mm. A vertical-type high-speed twin-roll caster can cast aluminum alloy strips at a speed higher than 10 m/min and a roll load smaller than 550 N/mm due to the effect of the large thermal conductivity of copper alloy rolls, compared …
Aluminum (Al) alloys have been the most popular choice in various applications to achieve an optimum strength-to-weight ratio. Al sheets/strips products can be economically produced by the twin-roll casting process. However, the cast strips possess several cast defects, which degrade the quality of the products. A detailed study on as …
strips are cast by the lower twin roll caster [2-4]. Casting the overlay strips and bonding them to the base strip are simultaneously carried out at the lower twin roll caster. The molten metal of the overlay strip is poured after the base strip is inserted between the rolls of the lower twin roll caster. Therefore, the melting point of the base

Two types of high-speed twin-roll casters and a single-roll caster equipped with a scraper were proposed. One of the twin-roll casters is a vertical-type high-speed twin-roll caster, and the other twin-roll caster is an unequal-diameter twin-roll caster. The vertical-type high-speed twin-roll caster can cast strip at speeds of up to 120 m/min. …
This invention provides a twin-roll casting machine comprising a pair of cooling rolls (1) for solidifying molten steel and delivering a steel strip (3) through a roll gap (G), a non-contact-type sensor (6) for measuring a thickness distribution in a plate width direction in a steel strip (3), marking means (8) for applying a mark (7) on a steel strip (3) for each rotation of the …
Twin-roll casting method for casting steel strand of thickness preferably 5 to 35 mm. Immediately downstream of the twin rolls, the cast strand is cooled by directing it through a stationary cooled mold (10). Subsequent to exiting the stationary mold, the strand is directed through a series of cooling rolls thereby further cooling the strand both by contact with …

A wire-inserted composite strip was cast using a downward melt-drag twin roll caster. The downward melt-drag twin roll caster was easily modified to a twin roll caster for the composite strip by simply attaching a coil of wire. Wire of either 0.3 and 0.6 mm diameter could be inserted continuously both inside and at the surface of the strip.
The solidification process in strip casting using a vertical-type high-speed twin-roll caster was clarified by inserting a 0.1 mm diameter K-type thermocouple into a strip during casting. The roll speeds of the copper rolls were 10 m/min and 30 m/min, and the roll loads were 5 kN and 20 kN. Al-Si alloys with a Si content of 2%, 6%, and 12% …

Twin-roll casting (TRC) is a technique of which cast strips are produced by a combined process of casting and rolling [1, 2, 3]. Despite TRC possesses advantages of low production costs [4, 5] and high cooling rates that refines the microstructures [6, 7], macro segregations are often inevitable during TRC
Two types of high-speed twin-roll casters and a single-roll caster equipped with a scraper were proposed. One of the twin-roll casters is a vertical-type high-speed twin-roll caster, and the other twin-roll caster is an unequal-diameter twin-roll caster.

Al-Li based alloys are attractive materials for the aerospace industry. The twin-roll casting of such materials could provide properties not achievable by conventional direct-chill casting and downstream processing methods due to significantly higher solidification rates. An Al-Li-Cu-Mg-Zr alloy was twin-roll cast with the same alloy containing a small addition of Sc. …
