Abstract

The invention aims to provide a castable specially used for coal-injection ducts of 12000T cement kilns. By adopting the castable, the problem of non-uniformity of tissue structures of current castables can be solved, the defects of poor constructability and castable segregation, more pores and non-uniformity of pore distribution caused by poor constructability are overcome, the phenomena of no wear resistance, spalling, no erosion resistance, and the like of kiln mouths can be effectively improved, and the service lives of the mouths of the cement kilns can be substantially prolonged.

Description

Technical field [0001] The present invention involves high -temperature materials in building materials, and specifically involves a 12000T cement kiln coal jet pipe pipe. Background technique [0002] At present, my country's new type of dry cement production line has developed rapidly, and cement production capacity has been severely excessive.Therefore, increasing the production efficiency and reducing production costs of cement production enterprises are the only way to maximize profits.And improving the operation rate of cement production line is an important condition for improving the efficiency of cement kiln production.However, the life of the cement kiln coal jet pipe has an important impact on the operation cycle of the entire production line.The use conditions of the coal jet pipe of the cement kiln are harsh. In addition to the high temperature of up to 1400 ° C in the kiln, it is also washed out of the cement kiln clinker.Therefore, higher requirements are put forwa...
