摘要 介绍了碳钢焊接球形蒸煮容器的工作环境,分析了由于工艺复杂和可能存在的焊接缺陷而导致碳钢焊接球形蒸煮容器形成裂纹、壁厚减薄的失效形式。提出延长碳钢焊接球形蒸煮容器焊接接头使用寿命的主要措施是通过调整蒸煮液配方严格控制蒸煮液的pH值,优化操作工艺,采用适当的焊接材料和合理的焊接工艺进行焊接,整体热处理等。 Abstract: Welded carbon steel spherical cooking container is often used as cooking equipment for paper-making process. The failure modes of welded rotary digester are cracking and thinning caused by the complexity of the cooking process and possible welding defects existing in welded rotary digester. The service life of rotary digester could be prolonged by adjusting the main recipe to control the pH value of the cooking liquid strictly and taking appropriate welding materials and reasonable welding process.
