转化炉是化肥生产工艺流程中的重点设备之一,其运行直接关系到整个化肥生产系统的正常生产。转化炉是每次化肥检修的重点项目,而转化炉焦炉气入口Φ273×14的0Cr25Ni20管道和富氧空气入口Φ133×6及Φ159×8的0Cr25Ni20管道的更换则是这个检修项目工作的关键所在,主要表现在对口焊接工作中。为了在时间紧、任务重、条件差、技术含量高的情况下,确保生产尽快恢复。通过分析、试验、归纳、总结、解决了在焊接中多次出现裂纹难焊接的技术问题,保证了检修质量,缩短了检修工期,为公司节约资金和减少损失几千万元,取得了较好的效果。下面浅谈在更换转化炉0Cr25Ni20管道焊接中的一点思考。
Reformer is one of the key equipment in fertilizer production process, and its operation is directly related to the normal production of the entire fertilizer production system. The reformer is the key project for each fertilizer overhaul, and the replacement of the 0Cr25Ni20 pipe with Φ273 × 14 Φ273 × 14 for the converter and the 0Cr25Ni20 pipe with Φ133 × 6 and Φ159 × 8 for the inlet of oxygen-enriched air is the key to the maintenance work , Mainly in the work of counterpart welding. In order to be tight in time, heavy tasks, poor conditions, high technical content, to ensure that production resume as soon as possible. By analyzing, testing, inducing, summarizing and resolving the technical problems that welding cracks frequently occur during welding, the quality of inspection and maintenance is shortened, the maintenance period is shortened, the company can save money and reduce the loss by tens of millions yuan, Effect. Here to talk about replacing the converter 0Cr25Ni20 pipe welding point of thinking.
