refractory acid brick lining for high temperature oven
High temperature oven acid brick lining
Coke oven acid brick lining are made by selecting high-quality superior clay and acid-resistant raw materials, through grinding, scientific proportioning, clay refining, high-intensity pressing and high-temperature tunnel kiln firing.
Performance characteristic
1. Acid-resistant brick blocks have a high density and low water absorption rate, so they have good compressive strength, are resistant to acid, erosion and corrosion, and can work in harsh environments.
2. Acid clinker in resistance to temperature change not cracking, wide application range.
3. Acid clinker as a protective lining equipment, high bond strength and the binder, the lining is not easy to fall off, long service life.
