In order to study the influence of the thrust/tension (0 ~ 15 MPa) on rolling process of stainless steel (Crl8Ni8

2 mm thickness tube)/low carbon steel (0. 06% ~0. 12% C

4>16 mm

round bar) clad rebar

a finite element model for clad rebar rolling process is established by using finite element software Msc. Marc. The influence of thrust/ tension on lateral spread and contact stress of interface of stainless steel/carbon steel clad rebar and circumferential thickness of stainless steel wall is studied by simulation

the key point is to study the thrust rolling on bonding strength of both metals. Results show that with exerting tension the lateral spread of rolling stock decreases but increases with exerting thrust with increasing thrust and decreasing tension the contact stress between clad stainless steel and core carbon steel increases. The thrust rolling is available to bond both metals and increases the bonding strength of clad stainless steel and core carbon steel.
