摘　　要：为了研究推/张力(0～15 MPa)对不锈钢(Cr18Ni8,2 mm壁厚管)/碳钢(0.06%～0.12%C,Φ16 mm,圆棒)复合钢筋轧制过程的影响,应用有限元软件Msc.Marc建立了复合钢筋轧制过程的有限元模型。通过模拟考察了推/张力对不锈钢/碳钢复合钢筋的宽展变形,结合面的接触应力和不锈钢圆周壁厚的影响,重点通过实验考察了推力轧制对两金属结合强度的影响。结果表明,施加张力后轧件宽展量减小,而施加推力后其值增加;不锈钢壳与碳钢芯间的接触应力随推力的增加、张力的降低而增大。推力轧制有利于两金属的复合,可以提高复合不锈钢和碳钢芯的结合强度。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, φ16 ram, 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 wail 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.
