我国催化裂化装置的一些设备,应用高铝水泥衬里(即矾土水泥衬里)已有二十多年。工程质量好的衬里,使用十年以上也无需大面积修补。本文除介绍这种衬里的配比和性能以外,着重从施工角度提出保证质量的要点。
Some equipment of China’s catalytic cracking unit has been used for more than 20 years in high-aluminum cement linings (ie alumina cement linings). Good lining quality of the project, no need for large area repair for more than ten years. In addition to introducing the lining ratio and performance, this paper focuses on the key points of quality assurance from the perspective of construction.
