国营农场应用氧炔焰喷焊技术修复农机旧件,自1975年开始由黑龙江垦区友谊农场八分场搞起来的,现已在农垦系统逐步推广。几年来的应用,农垦系统已建立了六十多种典型旧件的喷焊修复工艺,在修复拖拉机,汽车和各类农牧机械的磨损方面确实效果明显。 1.喷焊后的零件可延长使用寿命二至五倍例如五铧犁犁铲:把喷焊与未喷焊的装在一台犁上,翻地885亩后检查其结果。未喷合金粉的磨损8毫米,刃口变钝,耐用度为111亩/毫米。在犁铲宽度上单面喷焊合金粉的磨损3毫米,耐用度295.0亩/毫米,延长使用寿命2.7倍;在宽度上双面喷焊合金粉的磨损2毫米,耐用度为442.5亩/毫米,延长使
State-owned farms using oxygen acetylene flame spray welding technology to repair the old farm machinery, since 1975 Heilongjiang reclamation area Friendship Farm eight outreach outreach, has been gradually promoted in the land reclamation system. In recent years, the system has established more than 60 kinds of typical old parts of the spray welding repair process, in the repair of tractors, vehicles and all kinds of farming machinery and equipment is indeed a significant effect of wear and tear. 1. Sprayed parts can extend the service life of two to five times, such as five -shaped plow plow shovel: Spray welding and not spray-mounted on a plow, turn 885 acres and check the results. 8mm unfinished powder wear, blunt edge, durability of 111 acres / mm. 3mm wear resistance 295.0 mu / mm, 2.7 times longer service life; 2 mm wear resistance of double side spray alloy powder on width, durability 442.5 mu / mm , Extended to make
