摘要
An innovative short process rolling has been proposed to produce high performance clad plates of wear-resistant steel/carbon steel with lower production costs. The NM400 and Q345B cast billet instead of traditional hot-rolled plates were chosen to prepare composite steel ingots. The interface morphology, microstructure, and mechanical properties of clad plates with 45%, 60%, and 70% reduction ratios were analyzed and detailed using metallographic microscopy, scanning electron microscopy, and energy dispersive spectroscopy. The results demonstrate that the improvement of the reduction ratio effectively promotes the grain refinement of clad plates and the metallurgical bonding of dissimilar metals. The bonding interface of the clad plate is straight and clear when the reduction ratio is 70%, the distribution of alloy elements is uniform, and the grain refinement is apparent. The tensile strength of the clad plate rolling by the short process rolling reaches 626 MPa, the bonding strength reaches 484 MPa, and the elongation reaches 21%. These results exceed national, international, and industry standards.
