Finite Element Simulation Analysis of Multi-Stands Three-Roller Cold Rolling Process for Double Metal Composite Seamless Steel Tube

Abstract

The numerical simulation of the Y-type three-roller two stands cold rolling stainless steel/carbon steel double metal composite seamless steel tube process was conducted through the finite element analysis of the elastic-plastic by applying the MSC.MARC software. Based on the numerical simulation, the character of stress and strain distribution parameters during the Y-type three-roller two stands cold rolling were obtained by the finite element analysis, and acquired the section pass deformation figure. The distribution of the axial stress, circle stress and radial stress were drawn below the Y-type mill along the circle. The mechanism of the tube cold rolling process and the effect of the forming steel tube both the diameter and wall thickness accuracy were explained according to the stress distribution. The results of the research can be applied to the design of the technical parameters in the forming process.

Microstructure and Corrosion Property of Prepared CoCrW Coatings on the TC4 Surface by Laser Cladding

“…Metal materials find extensive applications across various industries, making the enhancement of their surface properties crucial [1][2][3]. The TC4 alloy, colloquially termed as the "space metal" and "ocean metal", is prevalently utilized in sectors such as aerospace and national defense, owing to its commendable comprehensive performance [4].…”

Numerical Simulation and Experimental Confirmation of a Bimetallic Pipe Forming Process

“…In these mechanically bonded pipes, under large bending loads, the liners undergo plastic deformation, which results in non-reversible liner wrinkling. This wrinkling impedes the flow and significantly reduces the performance of the pipeline [4]. Pipes are classified into ERW, JCO, and UOE pipes according to their cold forming processes.…”
