| 摘 要： | 通过宏观检查、化学成份分析、显微组织观察,对XKP-560破胶机辊筒光辊开裂掉块原因进行了分析。结果表明:生产工艺不合理造成了辊筒显微组织和机械性能未达到使用要求,发现夹渣、石墨漂浮、较粗大的层片状珠光体组织存在,材料白口层深度超标影响辊筒的机械性能,焊接修补工艺不合理亦会产生较大的焊接应力,增大了辊筒开裂倾向。

| Abstract: | With the macrographic method, chemical composition analysis and microstructure observation,an analysis was made of the reasons about Swap Blocks of the Roller of XKP-560 Financials Plastic Machine.The experimental results show that the mechanical properties and microstructures cannot meet the needs of operating requirements due to the unreasonable production process. It has been discovered that there are slags, graphite floating, coarse pearlites and the thickness of white microstructure affects the mechanical properties. Moreover, the unreasonable repair welding results in greater welding stress which increases the crack tendency. |
