The Rising Prevalence of Castable Refractory Monolithics
The Rising Prevalence of Castable Refractory Monolithics
May 11, 2018

Castable refractory has witnessed an upturn in the use of castable refractory monolithics in the last few decades. In fact, castable refractory monolithic production accounts for more than half of total production.


Monolithic castable refractories have begun to displace their brick brethren for a number of reasons. Not least, being readily available, easier and cheaper to install and with fewer corrosion-susceptible joints, are making them the material of choice.


The rising quality of castable refractory monolithics has made them the preferred refractories, even over bricks.


Monolithics can trace their roots to the earliest decades of the twentieth century, but their versatility, wide use of refractory materials which offer a good blend of performance and cost effectiveness have made them, and equivalent if not better performance compared to shaped refractories has made them the material of choice in recent years.


So effective have castable refractory monolithics proven, that many industries using them for high heat and pressure operations are finding that they can be reused; testament, indeed, to the superior quality of castable refractory monolithics.


Castable refractories commonly contain high alumina cement. This can be used to form desired shapes, or can even be cast in place. Then, unless the refractory is free flowing, vibration or a mixture with water is used to place the refractory.


Castable refractory is used widely nowadays: in blast furnaces, ladles, soaking pits, cyclones and transfer lines of catalytic cracking unit vessels in petrochemical industries, and much more besides.


There are variety of monolithic refractories. Just to enumerate a few:

  • Plastic refractories – These are tempered with water or added with a binder
  • Patching refractories – Soft plasticity, which allows them to be pounded into place
  • Mortars – Mortars consist of finely ground refractory materials mixed with water; used for layering and bonding shaped refractory


FibreCast is a global provider of high performance refractory products and a trusted provider to many industries. We offer a full line-up of high quality monolithic castable refractory products. We work with our clients to develop custom solutions for their unique applications.

Can I use this in a kiln or would you recommend another product?
