Finite Element Analysis of Large Plastic Deformation Process of Pure Molybdenum Plate during Hot Rolling

The rare molybdenum resources are being increasingly used in heavy industries. In this study, the common unidirectional and cross hot rolling operations, for pure plates, were numerically simulated by using MSC. Marc software. An elastic–plastic finite element model was employed, together with updated Lagrange method, to predict stress strain fields workpiece. results showed that there a typical three-dimensional additional compressive (?y> ?z > ?x) deformation zone, while could be divided into uniaxial biaxial tensile (?y ?x ?z). Tensile ?x increased accumulation of reduction decrease friction coefficient at edge width spread. More importantly, interlaced caused cross-commutations, which helpful repairing severe anisotropy created rolling. evolution temperature field plate investigated. surface quenching depth about 1/6 H under different initial temperatures reductions. addition, fundamental reason nonuniform distribution joint influence stress, contact friction, external resistance. By comparing theoretical simulation value experimental verification data, we found aligning well actual engineering.
