The Importance of Installation and Construction of Ceramic Fiber Modules

26


The installation technology and construction quality of ceramic fiber modules are the primary key factor to ensure the service life of refractory fiber furnace linings.

With standardized design and proper selection of refractory ceramic fiber modules with matching service temperature, as well as avoidance of mechanical collision and workpiece impact, the damage and falling off of refractory fiber furnace linings (except under corrosive atmosphere) are mostly caused by defective construction quality and improper installation processes.

Reserved pre-compression is generally adopted during the installation of refractory fiber furnace linings, yet this measure only eliminates gaps at room temperature. When heated, the surface fibers will lose part of their elasticity, so the reserved pre-compression cannot fully compensate for the gaps generated under high-temperature conditions

The Importance of Ceramic Fiber Module Installation & Construction

(1) Reduce the outer wall temperature of the furnace and cut down heat dissipation loss.


Compared with the traditional refractory brick furnace wall, after the installation of ceramic fiber module lining, the average temperature of the furnace outer wall and heat loss are significantly reduced, with stable performance and long service life. It maintains stable furnace temperature and uniform temperature zoning, which greatly improves product quality. Meanwhile, it optimizes the working environment for on-site personnel outside the furnace, lowers maintenance frequency and reduces labor costs.

(2) Remarkable energy-saving effect.

The most direct economic benefit lies in reduced heat loss, lower fuel consumption and effective cost control for enterprises. No furnace drying is required after installation, which saves considerable drying time. In addition, ceramic fiber modules feature excellent resistance to rapid temperature changes and are not affected by furnace startup, shutdown and maintenance. With proper installation and daily maintenance, the average service life of industrial kilns can reach more than 5 years.
