双ロールキャスターによるA3003/A4045/A3003 Al合金3層クラッド板の作製

抄録

By applying twin-roll casting as a method for producing thin plate directly from the melt, a vertical type tandem twin roll caster prototype was fabricated. In this equipment, twin roll casters more than two were set at the tandem position. Aluminum alloy three layers clad strip, of which the temperature of the liquidus line of the core strip was lower than that of the overlay strip was fabricated by this caster. As experimental samples, A4045(temperature of the liquidus line:585°C) was used for the core strip and A3003(temperature of the liquidus line:655°C) was used for the overlay strip. In order to prevent melting of the clad strip by solidification latent heat, the core strip and the overlay strip were bonded after cooling the core strip. As a result of cooling the core strip to 530 to 450 °C, Fabrication of the three layers clad strip was possible. In order to investigate the bond strength, cool rolling and bending test was conducted. As a result, The clad strip was not peeled off at the interface.
