针对选煤厂转运溜槽在高速煤流冲刷和大块矸石冲击下磨损快、维修周期长及动火风险高等问题，研发陶瓷—金属—橡胶梯度复合耐磨衬板与模块化铠装结构。测试结果表明：复合衬板质量损失率40.0 mg/h，为原衬板的1/6.13；平均失效冲击次数37 800次，为原衬板的3.15倍；界面平均剪切强度12.14 MPa，表面粗糙度Ra平均1.86 μm。文家坡选煤厂累计完成383.1 m²耐磨铠装施工，单次维修时间缩短75%，高磨损工位停机检修频次降低60%以上，溜槽复合耐磨技术年净效益30.15万元。材料梯度复合与模块化快换协同可显著提升溜槽耐磨、抗冲击、本质安全与全生命周期经济性。
A ceramic-metal-rubber gradient composite liner and modular armored chute were developed to address rapid wear, long maintenance duration and hot-work risks of coal transfer chutes under high-velocity abrasion and gangue impact. Laboratory tests and industrial verification were conducted. The mass-loss rate of the composite liner was 40.0 mg/h, compared with 245.0 mg/h for the original liner, corresponding to a relative wear resistance of 6.13. The average failure impact number was 37,800 and the relative impact life was 3.15. The average interfacial shear strength was 12.14 MPa and the mean surface roughness Ra was 1.86 μm. A total of 383.1 m² of armored lining was installed in Wenjiapo Coal Preparation Plant. The maintenance time was reduced by 75%, the shutdown frequency caused by liner wear was reduced by more than 60% at high-wear positions, and the reported annual net benefit of the chute wear-resistance technology was 301,500 CNY. The combination of gradient composite materials and modular rapid replacement significantly improves wear resistance, impact resistance, maintenance safety and life-cycle economy.
