Abstract

CéLULA DE RESFRIAMENTO BRUSCO POR FLUXO DE GáS PARA PEçAS EM AçO. A presente invenção refere-se a um processo de resfriamento brusco de uma carga em aço por fluxo de um gás ao nível da carga por intermédio de um meio de arrastamento do gás. O meio de arrastamento é comandado para fazer fluir o gás ao nível da carga a uma velocidade que varia segundo um perfil de velocidades do qual pelo menos uma parte compreende, sucessivamente, um patamar a uma primeira velocidade (44) e um patamar a uma segunda velocidade (46) superior à primeira velocidade.
