AI Technical Summary
Traditional furnace lining materials have high thermal conductivity and poor thermal shock resistance. They are prone to cracking and falling off after long-term use. Furthermore, all-fiber modules are prone to shrinkage and falling off under airflow scouring and erosion, resulting in low maintenance efficiency.
The furnace lining is made of modular rigid ceramic fiberboard, which is fixed by trapezoidal splicing blocks and stainless steel plates. Combined with ceramic fiber blankets and glue filling, it forms a stable furnace lining structure. Damaged parts can be disassembled and replaced individually.
It improves the overall stability and maintenance efficiency of the furnace lining, reduces maintenance time, and maintains good insulation performance and aesthetics.
