Abrasion is particularly prevalent in areas that experience high material flow rates or turbulence, such as in the taphole or launder systems. 4. Corrosion: Monolithic refractories can be subjected to corrosion from the gases, liquids, and solids present in the iron and steel production environment. Corrosion can occur due to the presence of oxygen, water vapor, and various chemical species, such as carbon monoxide and sulfur compounds. It can lead to the formation of corrosive products, such as oxides or sulfides, which degrade the refractory material over time. 5. Mechanical stress: Monolithic refractories may experience mechanical stress due to factors like thermal expansion and contraction, vibration, or mechanical impact. Excessive mechanical stress can cause cracks or fractures in the refractory lining, compromising its integrity and leading to failure. To mitigate these failure mechanisms, proper selection of refractory materials, regular inspection, and maintenance are crucial. Additionally, designing refractory linings considering the specific operational conditions and using appropriate installation techniques can help enhance their performance and lifespan in the iron and steel industry.
