In glass furnaces, avoiding erosion of sidewall blocks is the key to ensuring the normal operation of the furnace and extending its service life. Here are some specific measures and suggestions:
1 Optimize design and material selection
a. Reasonably design the furnace structure:
Choose sidewall blocks of different materials and thicknesses according to the life and location of the furnace. Optimize the furnace structure to reduce the scouring and erosion of the sidewall blocks.
b. Select high-quality sidewall blocks:
Choose a sidewall block manufacturer with good reputation and reliable quality, such as SNR. Give priority to using sidewall blocks with excellent erosion resistance, such as fused AZS bricks.
2. Strictly control the furnace baking process
a. Inspection and cleaning:
Before ignition, carefully check and clean the expansion joints around the sidewall to avoid blockage of the expansion joints and damage to the blocks.
b. Design a scientific and reasonable heating curve:
Design a scientific and reasonable heating curve according to the material and characteristics of the sidewall blocks. Especially in the temperature range where the expansion of the fused refractory material changes greatly.
c. Reasonably open the cooling fan:
During the furnace baking process, according to the gradual increase in temperature, reasonably open and adjust the air volume of the sidewall cooling fan.
3. Optimize operation management
a. Improve melting operation ability:
Strengthen the training of melting operators and improve operation skills.
b.Use cooling air system correctly:
According to the erosion of sidewall blocks, adjust the position and air volume of cooling air nozzle in time.Avoid excessive or too small cooling air volume to keep the temperature of sidewall blocks stable.
c. Control the pile:
Control the shape and position of the pile by adjusting the composition and feeding method of the batch material.
Use the guide water bar, the blocking water bar and other devices to avoid the pile from directly scouring the sidewall blocks.Use the full width or quasi-equal width feeding pool structure to make the material layer thinner and reduce the impact angle of the pile on the sidewall.
4. Strengthen maintenance and thermal repair
a. Regular inspection and maintenance
b. Adopt advanced thermal repair technology
