Abstract

"LAMINADOR E MéTODO PARA OPERAçãO DO MESMO". Cilindros hidráulicos são proporcionados em um alojamento de modo a ficarem opostos aos rolos de trabalho e aos rolos secundários. Antes de uma porção extrema frontal de um material laminável ser encaixada entre os rolos de trabalho, a pressão do óleo de trabalho dos cilindros hidráulicos é ajustada em um valor de alta pressão para tomar alta uma força de compressão sobre os calços de rolos. Após o material laminável ser completamente encaixado entre os rolos de trabalho, a pressão do óleo de trabalho dos cilindros hidráulicos é ajustada em um valor de baixa pressão para tomar baixa a força de compressão sobre os calços de rolos.
