Regular inspections, repairs, and maintenance are necessary to address any issues such as cracks, erosion, or spalling. Developing a comprehensive maintenance plan and ensuring access to skilled personnel for repairs are essential aspects of designing a successful lining system with monolithic refractories.
- Q: How are monolithic refractories installed and repaired in iron and steel production facilities?
- Monolithic refractories in iron and steel production facilities are installed by first preparing the surface by removing any existing refractory materials and cleaning it thoroughly. The monolithic refractory is then mixed with water to form a workable consistency and applied to the surface using various methods such as spraying, troweling, or casting. After installation, the refractory is allowed to cure and dry before being heated gradually to the desired operating temperature. In terms of repair, damaged or worn-out monolithic refractories are typically removed by chipping or cutting, and the surface is again cleaned. The new refractory material is then mixed and applied to the repaired area using the same techniques as installation. It is important to ensure proper curing and drying of the repaired refractory before subjecting it to heat.
