作者在ML-10栓盘试验机上测定了刮板运煤机链环-中板材料间的摩擦系数,该摩擦系数随煤的类型、荷载的不同而变化。目前对刮板运煤机推荐使用的阻力系数远低于该摩擦系数,应给予修正。作者还在M-200型试验机上试验了Fe-314等离子喷焊、Fe-05灰弧堆焊等六种中板材料的耐磨性,结果表明Fe-314等离子堆焊材料和Fe-05炭弧堆焊材料具有较好的耐磨性,经井下运煤试验,这两种强化材料可使中板的耐磨寿命提高两倍。 The authors measured the friction coefficient between scraper coalloader link-plate material on the ML-10 bolt test machine, which varies with the coal type and load. The current recommended drag coefficient for scraper coal conveyors is much lower than the friction coefficient and should be amended. The author also tested the wear resistance of six medium plates, such as Fe-314 plasma spray welding and Fe-05 gray arc surfacing on M-200 testing machine. The results show that the Fe-314 plasma surfacing material and Fe-05 carbon Arc surfacing material has good wear resistance, the coal mine test downhole, these two kinds of reinforced materials can make the plate wear life increased by twice.
