Ceramic anchor
Introduction:
The ceramic anchor is an anchor brick made by molding and firing a refractory raw material.
Shape:
The shape of the ceramic anchor is that two ends are flat, and four sides are serrated to increase the contact area with the lining and to support.
Advantages:
1. It can withstand higher service temperatures, and is generally used in kiln linings for long-term use above 1200 °C.
2. It can withstand the erosion and corrosion of corrosive atmospheres.
3. It can be extended to the working surface to reduce the flaking of the monolithic lining.
4. Compared with the metal anchor, the contact area with the refractory lining is large, and thus has greater support ability.
5. The thermal expansion coefficient is equivalent to that of the monolithic refractory material, which can eliminate the cracking or peeling of the lining due to the thermal expansion mismatch.
Application:
Ceramic anchors are commonly used to secure thicker (more than 200 mm) monolithic linings.
