Hot Rolling Clad Symmetrical Billet for Producing High-chromiun Cast Iron/Low-carbon Steel Wear Resistant Composite Boards

Abstract

Abstract: The carbon steel and high-chromium cast iron plates were symmetrically cladded with a six-layer billet， and then multi-pass hot-rolled to prepare a wear-resistant composite plate at a temperature of 1 200 ℃ with 30% and 60% reduction rates.The microstructure of the samples was observed by SEM.The experimental results show that the plate deformations after hot rolling are straight and warping-free.Due to the coordinated deformation and stress release of the soft carbon steel during hot rolling， the sensitivity of hot deformation cracking of high chromium cast iron is reduced， and the brittle high chromium cast iron layer achieves a certain degree of thermal deformation.The two material interfaces with good quality， there is no discernable interfacial interlayers and gaps and other defects.Energy dispersive spectrometer（EDS） tests find that a transition zone free of carbides on the high-chromium cast iron sides and the hardness values on both sides of the interface continuously changes indicates metallurgical bonding between the two materials.

摘要： 通过对碳钢板和高铬铸铁板进行六层对称包覆组坯，在1 200 ℃下分别采用30%和60%压下率多道次热轧制备了耐磨复合板。使用扫描电镜对试样的微观组织和界面结合情况进行了观察。试验结果表明：热轧后板形表现平直无翘曲现象；热轧过程中较软碳钢层的协调变形和应力释放作用使得高铬铸铁热变形裂纹敏感度降低，脆性高铬铸铁层实现了一定程度的热变形；两种材质界面结合质量良好，无可辨别的沿界面的夹层和空隙等缺陷；通过EDS能谱检测发现在高铬铸铁侧有无碳化物的过渡区，界面两侧的硬度值连续变化，证明两种材料实现了冶金结合。
