Abstract The deformationrules of the stress and strain of piecing and rolling of tubes were explored withφ100 Assel pipemill as the research object. The finite elementsimulation method can be used to effectively analyze the deformation rules of 27SiMnsteel pipe in rolling process. The quantitative description of 27SiMn steeltube’s deformation in piercing and rolling process may provide theoretical referencefor the reasonable optimization of 27SiMn steel pipe production process in realpractice.
