Resumo
O presente trabalho tem por objetivo a fabricação de tiras metálicas a partir da liga de Alumínio 6061 em um fundidor de tiras metálicas, no qual foi instalado um motor elétrico de 1 CV para acionar uma esteira dupla com 14 roletes e um sistema de resfriamento para controlar a temperatura no processo de laminação. O alumínio fio aquecido até a temperatura de 900°C e vazado a uma temperatura de 750°C logo após a retirada da escória e da adição do refinador de grãos ou agentes nucleantes. A partir do vazamento do metal líquido observou-se a formação de tiras metálicas que ficaram congestionadas entre os cilindros do equipamento e o funil direcionador localizado entres os roletes e os cilindros da máquina, não permitindo a formação contínua das tiras que estavam sendo conformadas. Sendo necessário a implementação de novos equipamentos que possam direcionar com mais eficiência as tiras metálicas para os roletes que auxiliam no recolhimento das tiras geradas pelo fundidor de tiras metálicas.
The aim of this work is to manufacture metal strips from Aluminum 6061 alloy in a strip caster, in which a 1 HP electric motor was installed to drive a double belt with 14 rollersand a cooling system to control the temperature in the rolling process. The aluminum wire was heated to a temperature of 900°C and poured at a temperature of 750°C immediately after the slag was removed and the grain refiner or nucleating agents were added. As soon as the liquid metal was poured, the formation of metal strips was observed, which became congested between the cylinders of the equipment and the directing funnel located between the rollers and the cylinders of the machine, not allowing the continuous formation of the strips that were being formed. It was necessary to implement new equipment that could more efficiently direct the metal strips to the rollers that help collect the strips generated by the metal strip caster.
