The service life of refractory bricks for cement rotary kiln is generally between 2 and 5 years. It should be noted that in practical applications, due to kiln structure and operation management, the service life of refractory bricks may be further affected.
Therefore, the specific time of the service life needs to be evaluated and judged according to the actual situation, and the severely worn refractory materials should be replaced in time to ensure the normal operation of production. The following is an introduction to the factors that affect the service life of refractory bricks for cement rotary kiln, and how to improve the service life of refractory bricks for cement rotary kiln.
One. Factors affecting the service life of refractory bricks for cement rotary kiln
1. Production process
Different production processes will have different effects on the wear and corrosion of refractory bricks.
2. Kiln temperature
The working temperature of cement rotary kiln is very high, usually between 1300°C and 1500°C, high temperature will accelerate the wear and corrosion of refractory materials.
3. Kiln atmosphere
The atmosphere in the kiln also has a great influence on the corrosion of refractory materials, such as redox atmosphere, alkaline atmosphere, etc. will lead to wear and corrosion of refractory bricks.
4. Quality of refractory bricks
There are differences in the quality of products produced by different refractory brick brands and manufacturers, and good quality refractory bricks have a longer service life.
Two. How to improve the service life of refractory bricks for cement rotary kiln
1. Choose good quality refractory bricks
When purchasing refractory bricks, it is necessary to choose products with reliable quality, advanced production technology and stable performance, and conduct inspections in strict accordance with relevant standards and specifications.
2. Pay attention to the temperature control in the furnace
Reasonable control of the temperature in the kiln can slow down the wear and corrosion of refractory materials. Therefore, during the production process, attention should be paid to adjusting the rotation speed, strengthening the partition, changing the position of the burner and other measures to control the temperature.
3. Strengthen the cleaning of the furnace
Regularly clean up the ash, slagging and other substances inside the cement rotary kiln to keep the furnace clean and prolong the service life of the refractory bricks.
4. Use suitable refractory materials
According to different production processes and conditions, the selection of suitable refractory materials that meet the requirements can better meet the production needs and prolong the service life.
5. Enhance maintenance management
Strengthening the daily inspection, maintenance and maintenance of cement rotary kiln equipment, regular replacement and repair of refractory materials can prolong the service life of refractory bricks.
Generally speaking, in the production operation, attention should be paid to the reasonable control of the temperature of the cement rotary kiln, the cleanliness of the furnace, the selection and maintenance of refractory materials, so as to improve the service life of refractory bricks.
