The Importance of Refractory Materials in Kiln Manufacturing

Refractory materials, also known as fire-resistant materials, possess an exceptional ability to withstand extreme heat, pressure, and chemical attacks without losing their strength or shape. These remarkable substances come in a wide variety of shapes and sizes. They can be molded or pressed to be used in the construction of floors and walls, designed in interlocking patterns or wedges, or even curved to perfectly fit the contours of boilers and ladles. Some refractory components are incredibly small, yet possess intricate and delicate geometries.

In the world of kilns, the mighty bricks reign supreme!

The brickwork within kilns and furnaces exhibits an extraordinary resilience, enduring the intense stresses of every firing and cooling cycle. Even when it appears to be on the verge of flaking away, it defies the scorching temperatures of 1700C / 3092F. However, there comes a point when aged and damaged refractory bricks begin to take a toll on productivity. Inefficient heat retention and the risk of damage to kiln ware from crumbling particles become an unwelcome reality.





Refractory Bricks

Referred to as firebricks, chamotte, and fire clay, these remarkable materials contain elevated levels of alumina and silica. The higher the alumina content, the denser the bricks become and the greater temperatures they can withstand. Fired at temperatures surpassing those of standard building bricks, they exhibit exceptional toughness and durability. However, it is important to note that firebricks cannot be effectively repaired, only replaced when necessary.



At Therser, we specialize in the repair and refurbishment of refractory lining and brickwork in kilns. Whether you need us to address just one or two sections or perform a complete rebuild, we have the expertise to handle it all. Additionally, we can upgrade the insulation during the process by installing a modern alternative that offers greater heat efficiency, resulting in lower running costs.
