Resumo
Over the past few years, many modern hot rolling mills have been built worldwide for hot strip production. In both new and existing mills, it is necessary to use optimally suitable roll grades. This paper analyses the specific features of two-high and four- high roll stands in hot rolling mills and presents optimum work roll grades. These include rolls with a working layer of hot-working steel and high-speed steel. Experience has shown that using such roll grades not only substantially reduces wear, but can also significantly extend roll life. The consequences of mill accidents and stickers are made substantially less severe. This leads to a reduction in non- productive roll consumption and an increase in economic efficiency.
