我厂用于10t模锻锤生产线供风的苏式100m~3风泵低压缸体水套壳体冻裂。低压缸体水套壳体直径为1400mm,壁厚25~30mm,长1800mm,裂纹全长1285mm,裂纹处开成U形坡口。缸体材料为灰口铸铁。 100m~3风泵的损坏直接影响10t模锻锤及其配套设备的使用,停产一天将造成万元以上损失。为了尽快恢复生产,采用异质焊缝的冷焊工艺在现场抢修。
I plant for the 10t forging hammer production line for the Soviet-style 100m ~ 3 low-pressure water pump shell water jacket shell cracking. Low-pressure cylinder water jacket shell diameter of 1400mm, wall thickness 25 ~ 30mm, length 1800mm, crack length 1285mm, cracks opened into a U-shaped groove. Cylinder material is gray cast iron. 100m ~ 3 damage to the wind pump directly affects the use of 10t forging hammer and its ancillary equipment, stop production for a day will result in loss of more than million. In order to resume production as soon as possible, the use of heterogeneous weld cold welding repair process at the scene.
