我厂的颚式破碎机在生产过程中发生动颚板断裂(图1),严重影响正常生产。在无备件更换的情况下,采用焊接进行现场修复,取得了较理想的效果。 1.动颚板材质为ZG35Mn钢,属合金结构钢。选用结606焊条(直径4 mm)进行焊接,焊条需经350℃烘干1 h,随用随取。 2.为减少焊接工作量、焊接变形及便于 Jaw crusher in our factory is in the production process of moving jaw fracture (Figure 1), seriously affecting the normal production. In the absence of spare parts replacement, the use of welding site repair, and achieved satisfactory results. 1. Moving jaw material ZG35Mn steel, alloy steel. Selection of knot 606 electrode (diameter 4 mm) for welding, electrode to be dried by 350 ℃ 1 h, with the use of take. 2. To reduce the welding workload, welding deformation and ease
