[0002] The CDQ rotary coke drum is mainly composed of a drum frame, drum lining, hook, octagonal beam, drum cover, guide wheel set, buffer seat and hydraulic lubrication system. The drum lining is the part in direct contact with the red coke, and the material of the drum lining needs to be both high temperature resistant and wear resistant. The outer edge section and straight section of the drum lining are usually made of QT600 material, and the cone section lining and bottom gate lining are usually made of ZG35Cr24Ni7SiN material. These two materials have good high temperature resistance and wear resistance and can be used in production in a short time.

[0003] Due to the frequent use of the dry coke quenching coke drum, the lining of the coke drum is burned or the lining falls off during use, which causes the problem of clogging of the rotary sealing valve of the dry coke quenching system, affecting the normal production of dry coke quenching. In addition, the service life of the lining is short during use, usually between 6-12 months. At present, when improving the lining material, castable linings are used in the coke drum. Castable linings can meet the equipment use requirements and avoid the problems caused by casting plates. However, when the original cast plate coke drum is converted into a castable drum, a new coke drum needs to be remade, which leads to great construction difficulty, high transformation cost and difficult transportation. In order to reduce the difficulty of construction and reduce the cost of transformation, the present application designs a quick-installation dry coke quenching castable coke drum lining.
