遵照毛主席“独立自主,自力更生”的伟大教导,为使尿素设备用材立足国内,以高速发展我国化肥工业,我国自行设计制造的24万吨/年大型尿素装置的关键设备——二氧化碳汽提塔采用耐蚀性好、我国资源丰富的钛材制造,今年一月在上海召开了设计审查会。会议认为,外径为φ2100mm厚度为400mm的20MnMo碟形管板爆炸复合5mmTA_1钛板工艺复杂、要求高、难度大,将该项目列为重点攻关任务。为总结攻关工作的进展情况,在宝鸡有色
In accordance with Chairman Mao’s “self-reliance, self-reliance” great teaching, in order to make urea equipment materials based in China, and to rapidly develop China’s chemical fertilizer industry, China’s own design and manufacture of key equipment for 240000 tons / year large urea plant - carbon dioxide stripper tower With good corrosion resistance and rich titanium resources in China, a design review meeting was held in Shanghai in January this year. The meeting considered that the 20mm OD tube disc with an outer diameter of φ2100mm and a thickness of 400mm was complex, high in demand, and difficult to demolish the composite 5mm TA_1 titanium plate. The project was listed as a key task. In order to summarize the progress of the research work, Baoji has colored
