Cement plant hard surface wear-resistant composite steel plate by the common substrate and surfacing wear-resistant layer of two parts, surfacing wear-resistant layer and the substrate is completely metallurgical, wear-resistant layer will not fall off. Wear layer generally accounts for the total thickness of 1 / 3-2 / 3, wear layer composite processing process, the anti-wear layer was cracked, and the crack can not extend into the matrix, otherwise it will affect the substrate carrying capacity. Anti-wear layer and the matrix can not exist between the cracks, or wear-resistant layer in the deformation process or in the use of off, can not play the role of anti-wear. Cracking cracks in the composite wear-resistant steel can be deformed as possible. High chromium alloy wear-resistant surfacing composite board, is a new type of high wear-resistant composite materials, which is the use of automated metal arc surfacing a new process method, the formation of eutectic high chromium alloy wear-resistant layer.
