Abstract

"PROCESSO PARA A FABRICAçãO DE MOLAS HELICOIDAIS OU DE ESTABILIZADORES". A presente invenção refere-se a um processo para a fabricação de molas helicoidais ou estabilizadores de aço, sendo que o material de partida é aquecido a uma temperatura acima da temperatura de recristalização, a estrutura é austenitizada, mantido com compensação de temperatura, depois é moldado e finalmente é resfriado bruscamente e temperado para formar martensita, sendo que, o material de partida é formado por barras de aço redondas, cuja temperatura de recristalização é compensada através do comprimento da barra em um forno de compensação, que depois são moldadas através de laminação inclinada, permanecendo em essência, retas, sendo que, após a ultrapassagem do grau de transformação crítico são executados processos de recristalização dinâmicos, em seguida, as barras de aço redondas, para a recristalização estática completa, são submetidas a um reaquecimento acima da temperatura de Ac3, depois são enroladas para formar uma mola helicoidal ou curvadas para formar um estabilizador e, finalmente, são resfriadas bruscamente e temperadas de austenita para formar martensita.
