复合耐磨钢板

RK双金属复合耐磨钢板已广泛应用于重工业领域,为我国工业设备、工件的磨损失效提供了重要的耐磨保护措施，极大地提高了设备、工件的使用寿命，为企业提高生产效率、降低生产成本做出了重要贡献。www.zhongguorunkun.com

RK双金复合耐磨钢板是采用明弧自保护全自动堆焊工艺，在普通钢板或不锈钢板表面堆焊复合一层具有高硬度、高耐磨性的高合金耐磨层，该耐磨钢板具有双金属性能，即工作层的高耐磨性和基体层的高塑韧性，为工业应用提供了便利的机械连接和焊条连接条件，可以实现卷筒、焊接、等离子切割、机械连接等加工。

复合钢板的耐磨层与基体层之间是完全冶金结合成为一体，耐磨层厚度均匀、表面平整，整张钢板的平整度与普通碳钢板相当。耐磨层面表有应力释放裂纹，该裂纹只存在于堆焊的耐磨层，不延伸到基体内，该应力释放裂纹可以大减小堆焊过程对基体产生残余应力和变形，进而避免降低基体强度，不会影响耐磨板的使用性能。耐磨层的主要成分为高碳高铬合金，根据不同用户的要求和使用条件，耐高温的耐磨板中还含有Mo、W、V、B、Nb、Ti等合金元素，耐磨层的金相组织提供为共晶+M7C3一次碳化物或复杂碳化物，可以实现耐常温、高温、强冲击、中等冲击、低应力冲击的高抗磨损性能。

Dual Wear ReSIStant Composite Steel Plates

RK Dual Metal Wear Resistant Composite Steel Plates have been widely used in heavy industries which also provide the wear-resistant protection against wear failure of equipments and work-piece, tremendously improved the life span of equipments and work-piece, they’ve made very big contribution on improving productivity and lowering cost to corporation.

RK Double Metal Wear-Resistant Composite Steel Plates adopts arts of open arc surfacing wielding self-protection, which have high hardness wear-resistant layer that is wielded on ordinary steel plates or stainless plates, this kind of wear-resistant steel plates have dual metal functionalities, two functions are high wear-resistance of working layers and high elasticity of the base layer. RK Dual Metal Wear-Resistant Composite Steel Plates provide convenience to machinery connection and wield rode connection. They can be curLED, wielded, plasma cut and machinery connected.

The wear resistant layer and the base layer of composite steel plates are combined into one, The thickness of wear-resistant layer is even and has smooth surface; the smoothness of whole steel plate is very close to ordinary carbon steel plate. The wear resistant surface has stress energy released micro cracks, these cracks are only existed on the wear resistant surface, not extended to the base layer. The stress released micro cracks can reduce base layer produced residual stress and deformation in surfacing wielding procedure, and thus avoiding lowering the strength of base layer, no influence on usability of wear-resistant plate. Wear resistant layer consists of high-carbon high-chromium alloy, according to different clients’ requests and conditions of use. High-temperature wear-resistant plate contains Mo, W, V, B, Nb, Ti, and other alloying elements. Wear resistant layer’s metallographic phase provides eutectic +M7C3 primary carbide or complex carbide, the layer can bear room temperature, high temperature, strong impact, medium impact and high wear property of low stress impact.
