Abstract
<B>DISPOSITIVO PARA O AJUSTE HIDRáULICO DOS ROLOS DOS SEGMENTOS DE GUIA DE LINGOTES DE UMA INSTALAçãO DE FUNDIçãO CONTìNUA<D> A invenção refere-se a um dispositivo para o ajuste hidráulico de componentes, especialmente dos rolos dos segmentos de guia de lingotes de uma instalação de fundição contínua com cilindros hidráulicos (2), que são divididos respectivamente por um êmbolo (12) com biela do êmbolo (13) em um espaço cilíndrico (9) e um espaço cilíndrico anular (11), em que os espaços cilíndricos (9, 11) são ligados alternadamente e em sentido contrário por elementos de comando bem como simultaneamente com uma fonte de pressão (7) e uma redução de pressão (5). As desvantagens das válvulas contínuas utilizadas até então como elementos de comando, principalmente grande sensibilidade referente à pureza e poder lubrificante do líquido de produção são evitados pelo fato de serem previstas válvulas de controle como elementos de comando. Estas são insensíveis quanto à pureza e da utilização de emulsão de água-óleo com líquido de produção.
