摘　　要：为延长刮板输送机中部槽的使用寿命,研究了在不增加硬度的前提下提高材料耐磨性的方法。通过在常规耐磨钢板材料中添加一定量的钛、碳等元素,经冶炼、轧制、热处理等工艺后,在常规马氏体基体中弥散大量微米级的TiC硬质颗粒,该颗粒改变了钢板的抗磨机理,在煤矸石、石英砂等磨料磨损钢板时,TiC颗粒阻碍了磨削犁沟的形成或变浅犁沟深度,进而减少磨料对钢板的磨损,实现在不增加设备加工成本的基础上延长设备运行寿命。单一测试和同工况对比测试结果表明:配套新型耐磨板的刮板输送机中板百万吨过煤磨损量较常规减少1/3以上,耐磨性显著优于同硬度等级进口材料,为提升刮板输送设备可靠性、实现煤炭资源安全高效开采提供了坚实的技术支撑。In order to improve the service life of the middle groove of the scraper conveyor,we explore the methods to improve material wear resistance without increasing its hardness.By adding titanium,carbon and other elements to conventional wear-resistant steel plate material,after smelting,rolling,heat treatment and other processes,a large number of micron-size TiC hard particles are dispersed in conventional martensite matrix,which changes wear-resistant mechanism in the use of steel plate.When steel plate is worn out by abrasives such as coal gangue and quartz sand,TiC particles hinder the formation of grinding groove or make groove depth shallower,thus to reduce the wearing of steel plate.The service life of equipment is prolonged without increasing equipment manufacturing cost.Through single test and comparison test under the same working conditions,the worn out rate of the new wear-resistant deck plate after conveying one million tons of coal is brought down by over 1/3 than that of plate,and the wear-resistance is better than that of imported materials of the same hardness level,which provides solid technique support for improving the reliability of scraper conveying equipment and realizing safe and efficient mining of coal.
