一、两器衬里的简况六十年代初,我国从国外引进Ⅳ型密相输送流化催化裂化炼油技术。其两器(再生器和反应器)中有衬里,当时由于没有有关的衬里技术资料,也没有相应的进口衬里材料,这就提出了用国内的材料进行试验研究的课题以及衬里施工。两器筒体衬里(双层衬里)试验是从一九六三年初开始,石油部委托冶金部建筑研究院进行试验研究。对隔热层采用火山灰矽酸盐水泥为胶结剂,以轻质耐火粘土砖砂为骨料,以 First, the two liner profiles In the early 1960s, China imported from abroad IV type dense phase fluidized catalytic cracking refinery technology. There were linings in both of them (regenerator and reactor). At that time, due to lack of relevant lining technical information and corresponding imported lining material, the subject of domestic research on materials and lining construction was proposed. Two-cylinder liner (double lining) test is from the beginning of 1963, the Ministry of Petroleum commissioned the Metallurgical Construction Research Institute for pilot study. Insulation layer of ash ash cement for the cement, light refractory clay brick sand as aggregate, with
