Statistical analysis and calculation of metal forming during rolling of H-profiles on the universal rail-beam mill
Abstract
A new method of calculating the roll pass design for universal rail-beam mill based on the results of statistical generalization of existing technological procedures rolling H-profiles and on the application we have developed a mathematical model of metal forming during rolling in the universal grooves.
With the application of the developed method have been calculated roll pass design of the finishing train tandem of universal rail-beam mill for rolling I beam 35B2. A characteristic feature of the regime are obtained almost the same reduction ratio of the web and flanges during rolling in every universal groove: the difference values and are 0,4-2,4%, ie uniform deformation of the metal is achieved along the profile elements, which contributes to a high quality I-beam.
