Abstract
In order to improve the surface quality of strip head, and help to reduce the number of spare parts roller volume, as well as hot rolling mill to increase production efficiency. Study the rules of stress and pressure distribution in the expansion course of hot-rolled strip steel among layers in the full-hydraulic underground coiler machine. Analysis the process in the pressure distribution of the impact of roll pressure and a number of factors during the coil winding such as tension, friction, roll diameter, the effects of plastic deformation, and so on. For the analysis of the drum pressure and tension, friction, with the relationship between diameter. At the same time, developed a computer program may be the impact of each parameter calculated and analyzed. The study results can provide important reference value for expansion process of coiler and improvement the quality of production for hot continuous rolling strip steel.
