The use of refractory bricks in the cement kiln directly affects the operation rate of the cement kiln and the output of clinker. The service life of new dry-process cement kiln refractory bricks should not be less than 10 months,Refractory Bricks and the brick consumption per ton of clinker should be less than 500 grams. Otherwise,Refractory Bricks the reasons that affect the life of refractory bricks should be carefully analyzed in order to improve and increase. What affects the service life of refractory bricks in cement kilns: First,Refractory Bricks the quality and configuration of refractory bricks;
Second, the process and production status; third,Refractory Bricks the storage and construction of refractory bricks. The first aspect is the premise. Choosing high-quality products and reasonable selection and configuration are necessary conditions to ensure normal use. Proper storage and high-quality masonry are a reliable guarantee for prolonging the service life of refractory bricks!
Kiln lining bricks will suffer comprehensive damage of mechanical stress and chemical stress during production. The damage phenomena and reasons are now analyzed as follows: mechanical stress damage,Refractory Bricks thermal expansion and squeezing of refractory bricks,Refractory Bricks when the kiln temperature rises to a certain extent, thermal expansion is in the axial direction of the kiln Pressure will be generated,Refractory Bricks causing adjacent refractory bricks to squeeze each other. When the pressure is greater than the strength of the refractory brick, the surface of the refractory brick will peel off. In response to this situation,Refractory Bricks the following measures should be taken: 1. Dry-lay refractory bricks, set up reasonable side cardboards,Refractory Bricks and leave 2mm fire mud joints for wet-lay refractory bricks; 2. Leave suitable brick retaining rings.
