Analysis of Rolling Pressure in Asymmetrical Rolling Process by Slab Method

TIAN Yong , GUO Yanhui , WANG Zhaodong , WANG Guodong

钢铁研究学报(英文版)

The plane strain asymmetrical rolling was analyzed using slab method. The contact arc was replaced by parabola, and the constant surface friction status was adopted during the analysis. The deformation area was divided into three zones according to the direction of the friction. Then, the three zone...

Effects of Warm Deformation on Mechanical Properties of TRIP Aided Fe-C-Mn-Si Multiphase Steel

TIAN Yong , LI Zhuang

钢铁研究学报(英文版)

Warm deformation tests were performed using a kind of tubby heater. The microstructures and mechanical properties of an Fe-C-Mn-Si multiphase steel resulting from different warm deformation temperatures were investigated by using LOM (light optical microscopy), SEM and XRD. The results indicated tha...

Calculation Method of Optimal Speed Profile for Hot Plate During Controlled Cooling Process

WANG Bingxing , CHEN Xiaolin , TIAN Yong , WANG Zhaodong , WANG Jun , ZHANG Dianhua

钢铁研究学报(英文版)

The healthy and rapid development of the controlled cooling technology was hampered by the uneven cooling phenomenon. During the process of hot plate production, the homogeneous cooling along the length direction of plate was constrained by lots of factors. And because the speed was a flexible contr...
