刮板输送机中部槽制造及修理工艺研究

Research on Manufacturing and Repairing Technology of Middle Trough in Scraper Conveyor

通过选用零部件材料、焊接材料、保护气体、焊接设备及调整焊接工艺参数等制造了多种中重型刮板输送机。分析了刮板机中板在不同磨损情况下,中部槽修理的不同工艺流程,提出了用铬-钼系列耐磨焊丝对中板磨损不太严重的中部槽进行堆焊,有效提高了中部槽使用寿命,降低了开采成本。

While manufacturing kinds of medium and heavy scraper conveyors, more attention should be paid on the preferred parts materials, welding materials, protective gas, welding equipment and adjust the welding process pa-rameters. The paper analyzes the different technique processes while repairing the middle trough of scraper, and puts forward the mass welding process with chrome-molybdenum wear-resistant welding wire for middle trough which is not worn severely, working life prolonged, total cost reduced.
