Austrian refractories manufacturer Rath successfully developed the refractory lining of a test roller furnace for the ceramics industry

In refractory lining maintenance, recommendations for repairs and relines often consist of selecting a similar or equivalent material to replace the original. Sometimes that’s sufficient.

A significant concern when manufacturing aluminum metal is the practical service life of the furnace. The service life is largely driven by the refractory lining’s ability to resist the various operating conditions within the furnace, such as high temperature, temperature variation, chemical corrosion and mechanical abrasion.

Insulating castable refractories Plicast LWI 24 HS and aluminum-resistant Plicast Al-Tuff LWI 24 HS are both a safe choice for lightweight refractory linings inside high-temperature furnaces, incinerators boilers.

It is estimated that up to 40% of refractory-lining failures can be attributed to a problem with the design of the anchor system or improper installation. This is a significant number.

Good linings require the best attachment methods. Challenges exist, but developments are overcoming the challenges.
