平地机导板工作时产生滑动磨损与磨粒磨损。在平地机的一个大修期内,导板单面厚度方向的磨损量可达2.0mm左右。导板磨损后直接影响工作装置的正常工作。介绍导板的耐磨合金堆焊工艺。采用表面工程技术中的耐磨合金堆焊工艺,通过合理使用堆焊材料并采取焊前预热、焊后缓冷等严格的工艺措施,不仅使磨损失效的导板恢复了尺寸,还提高了耐磨性,而耐磨合金堆焊导板的成本仅为新件的30%左右。与整体40Cr调质件相比,耐磨合金堆焊导板的性价比可提高3倍左右。
Grader guide plates produce sliding wear and abrasive wear. In a grader overhaul period, the guide plate thickness of the direction of wear of up to about 2.0mm. Guide plate wear directly affect the normal work of the work unit. Introduction guide wear-resistant alloy surfacing process. The use of surface engineering technology wear-resistant alloy surfacing process, through the rational use of surfacing materials and to take pre-welding preheating, post-welding slow cooling and other stringent process measures, not only to restore the wear-resistant guide plate size, but also improve the resistance Grinding, and wear-resistant alloy surfacing guide the cost of only about 30% of new pieces. Compared with the overall 40Cr conditioning parts, wear-resistant alloy surfacing guide the cost can be increased about 3 times.
