How shall Thin Layer, Erosion Resistant refractory linings be applied?

Thin layer, erosion-resistant refractory linings are designed to be applied with specific tools and methods that ensure proper adhesion and density. The selected approach involves using a handheld pneumatic rammer, rubber mallet, and/or wood block. This technique is effective because it allows for uniform distribution and compaction of the refractory material, which is crucial for achieving the desired mechanical properties and service life of the lining.

The pneumatic rammer helps to eliminate air pockets and ensures that the material is well-compacted, which enhances the strength and durability of the lining. The rubber mallet and wood block can be used to further assist in leveling and compacting the refractory, providing a smooth finish that can withstand the operational demands once the lining is in service.

Other methods, such as application by trowel, pouring into place, or using a spray gun, may not provide the same level of control over compaction and surface finish that is critical for thin layer applications. These methods may lead to inadequate bonding or insufficient density, thereby undermining the performance of the refractory lining.
