对国外热轧复合及国内爆炸复合生产的轧机用耐磨复合衬板的性能进行了对比分析, 主要包括界面抗剪强度、拉伸性能、冲击性能和耐磨性能。结果表明: 国外通过热轧生产的复合衬板的界面较为平直, 基材的韧性较高, 复材的耐磨性能优良, 综合性能良好;国内爆炸复合生产的衬板虽然界面结合强度较高, 但基材的韧性较低, 耐磨性能低于国外热轧生产的复合衬板的耐磨性能。根据耐磨复合衬板的组织及性能结果, 对国外热轧复合衬板的组织控制工艺进行了推测。

Two kinds of wear-resistant steel clad lining plate used in rolling mill, made by explosion and hot rolling methods at home and abroad, were investigated, and the shear strength, tensile strength, impact toughness and wear-resistant property were comparatively analyzed. The results showed that the interface of lining plate made by hot rolling was relatively straight between components, and the lining plate possessed good wear-resistant property and high toughness. Although the shear strength of lining plate produced by explosion was higher than the one made by hot rolling, the impact toughness and wear-resisting property were much lower than hot rolled one. According to the microstructure and mechanical properties, microstructure controlled process of lining plate produced by hot rolling was presumed.
