双金属复层耐磨钢板是专供大面积磨损工况使用的板材产品，是在韧性、塑性很好的普通低碳钢或者低合金钢表面通过堆焊方法复合一定厚度的硬度较高、耐磨性优良的耐磨层而制成的板材产品。
在复合耐磨板内预埋金属骨架，金属骨架上设有连接孔或者连接螺栓。
A metal framework is embedded in the composite wear-resistant plate, and the metal framework is provided with a connecting hole or a connection bolt.
此法使耐磨层的硬度、耐磨性有明显提高，延长了耐磨板、耐磨环的使用寿命。
The hardness and wear resistance of the layer are significantly increased, service life of wear plate and wear ring is extended.
衬板、搅拌叶片均采用高硬度、高韧性的耐磨合金铸钢，使用寿命长。
Lining board, mixing blades adopts high hardness and high toughness wear-resistant steel and long service life.
