How to Extend the Service Life of Corundum Bricks?
Corundum brick is an extremely wear-resistant brick material with excellent properties such as high hardness, corrosion resistance, high-temperature resistance, wear resistance, and impact resistance. Its main component is alumina, which is sintered at high temperatures. Corundum bricks are widely used in steel, non-metal, cement, chemical, electric power, metallurgy, and other industries and are a very important building material. So, how to extend the service life of corundum bricks? Rongsheng refractory material manufacturer teaches you to analyze and solve this problem. First of all, we need to look at the factors that affect the service life of corundum bricks. Then specific issues are analyzed based on these factors.
What are the factors that affect the service life of corundum bricks?
1. Corundum bricks are prone to bursting. Especially when the temperature changes rapidly, internal stress will form, causing surface peeling and cracking.
2. The gaps between corundum bricks are not tightly sealed. The oxide scale gets into the gaps and sticks to the top, making it difficult to remove. Hitting with a steel hammer can easily cause damage.
3. The bottom of the corundum brick needs to be padded with hard refractory material. It is not allowed to use loose insulation materials for paving, and it is not allowed to use only part of the paving to prevent the corundum bricks from loosening.
4. The "cutting" of corundum bricks by continuous casting billets will reduce the service life. When the billet is put into the furnace, the placement should be adjusted to avoid cutting.
5. Improper expansion joints will cause premature damage to corundum bricks and reduce their service life.
Corundum bricks have very high hardness, with a hardness value of level 9, which is harder than steel. Therefore, it is widely used in steel smelting, metallurgy, refractory materials, and other industries. In these industries, the temperature inside the furnace is extremely high, and conventional bricks cannot withstand the high temperatures and corrosion. Corundum bricks have high-temperature resistance and corrosion resistance and can withstand high-temperature, acid, and alkali corrosion in extreme environments, ensuring the stable operation of production equipment. In addition, corundum bricks also have good wear resistance. Production equipment in the steel industry requires frequent cleaning and cleaning. It is easy to wear and tear after long-term use, and traditional bricks cannot withstand this kind of wear and tear. But corundum bricks can withstand longer wear and tear, greatly extending the life of the equipment.
The use of corundum bricks can also reduce environmental pollution. Corrosive gases or liquids need to be used in some production, and traditional bricks are easily corroded after long-term contact, resulting in pollution. The corrosion resistance of corundum bricks can effectively solve this problem and avoid environmental pollution. In short, corundum bricks, as a special building material, have very special properties and can meet the needs of some extreme environments. Its use can ensure the stable operation of the equipment, extend the service life of the equipment, and avoid environmental pollution. As people's requirements for industrial equipment continue to increase, the market prospects for corundum bricks will become increasingly broad.
After understanding the usage characteristics and damage mechanism of corundum bricks, we can solve the problem of the short service life of corundum bricks in the high-temperature industrial kilns used. To purchase high-quality corundum refractory bricks, please choose a competent refractory brick manufacturer.
