催化裂化和重油催化装置是我厂两套重要的大型深加工生产装置,由于高温、高粉尘冲刷,其设备内表面必须敷设非金属耐高温耐磨衬里材料。即使这样,在一些条件苛刻高温高冲刷的部位,如旋风分离器、双动单动滑阀、阀后烟道等处仍经常发生衬里损坏、设备超温、磨穿泄漏,严重危及生产安全,甚至被迫停工抢修,造成很大的经济损失。近年来,由于科技进步,生产发展,国内很多厂冢纷纷上马,研制生产了多种牌号的高温耐磨衬里浇注料,这就为挑选试用新型耐磨 Catalytic cracking and heavy oil catalytic device is two sets of important large-scale deep processing production plant in our factory. Due to high temperature and high dust erosion, the inner surface of the equipment must be laid non-metallic high temperature wear-resistant lining material. Even so, in some parts of the conditions of harsh high-temperature erosion, such as cyclones, double-action single-action slide valve, valve flue and other places are still often occur lining damage, over-temperature equipment, worn through leakage, seriously endangering the safety of production, Even forced to stop work repair, causing great economic losses. In recent years, due to advances in science and technology, production and development, many domestic mound have been launched, the development and production of a variety of grades of high temperature wear-resistant lining castable, which for the selection of new wear-resistant test
