Abstract

The invention discloses a method for prolonging the service life of a refractory material of a grate cooler. The method comprises the steps of adjusting the air volume adopted by a grate cooler system in a center control chamber, keeping the grate cooler system to be in a negative pressure condition, mixing refractory bricks and castable in the grate cooler, prolonging the service life of the refractory material of the grate cooler to be 16 months, reducing the brick wall area in the grate cooler, and prolonging the service life of the refractory material of the grate cooler to be 16 months. The method can overcome the defects in the prior art that the construction template is large in area, unreasonable in structure, complex in operation technology, and the like, so as to achieve the advantages of small construction template area, reasonable structure and simple operation technology.

Description

technical field [0001] The invention relates to the technical field of cement processing, in particular to a method for prolonging the service life of refractory materials of grate coolers. Background technique [0002] The fourth production line of Guangxi Yufeng Cement Co., Ltd. was successfully ignited and put into operation on October 15, 2008. The designed production process is a new dry process kiln with anthracite as the main fuel for pre-decomposition outside the kiln, and the designed output is 2,800 tons of clinker per day. In recent years, with the improvement of kiln process management level, the operation period of 4# kiln has reached more than 8 months. The hot end shell of the cold machine will burn red or even burn through due to the loss of the protection of the refractory material, which seriously affects the normal operation of the kiln and brings safety hazards to the site. [0003] Refractory materials refer to: the refractory materials currently used ...
