Abstract：

In order to study the rules of layers stress and pressure distribution in the expansion course of hot-rolled strip steel for the full-hydraulic underground coiler machine,the recursive formula of coiler pressure was derived in considering the strip steel different thickness,different layers,and friction influence before coiler expansion for hot-rolled strip steel.The results show that normal stress of strip has an upward trend with the increase strip layers,and tensile stress of strip steel has a downward trend with the increase of strip layers.The research achievement can provide important reference value for studing the expansion process of coiler and improving the quality of production for hot-rolling strip in industry.
