炼油厂和石油化工厂中,耐热混凝土衬里应用十分广泛。衬里可以解决钢材所难以解决的问题或降低成本,但要获得可靠的衬里,必须抓好三个环节:即衬里的设计、安装和安装后的养护、烘干。在进行衬里设计之前,设计者要对与衬里有关的情况进行凋查,即要搞清以下几点:(1)最高操作温度。(2)操作压力(包括某种操作气体的分压)。(3)与耐火材料接触的工艺介质的化学成分。(4)工艺过程中的杂质(这有时会成
Refractories and petrochemical plants, heat-resistant concrete lining is widely used. Lining can solve difficult problems or reduce the cost of steel, but to obtain a reliable lining, we must grasp the three areas: the lining of the design, installation and installation of maintenance, drying. Before proceeding with the design of the liner, the designer investigates the condition of the liner, ie to ascertain the following points: (1) The maximum operating temperature. (2) Operating pressure (including partial pressure of some operating gas). (3) The chemical composition of the process medium in contact with the refractory. (4) process impurities (which sometimes become
