What is a Refractory?

Refractories are ceramic materials designed to withstand unusually high temperatures while maintaining structural integrity. More heat-resistant than metals, they line the hot surfaces found in several processes in modern manufacturing.

Most often made of ceramics and used in metallurgical, glassmaking, and ceramics industries, refractories line devices like furnaces and kilns, which process materials at high temperatures. In addition to being heat-resistant, they must also be resistant to thermal shock, which occurs when an object is cooled from a high temperature quickly.

Refractories are built to withstand the test of time, lasting up to ten years. But aging is inevitable, especially due to the high temperatures they endure. Luckily, there are a few telltale signs you should watch out for that will let you know it’s time to replace them. These include cracks more than 1/16” thick, any crumbling, or any pieces coming off completely.

While they have many industrial uses, refractories are also present in kilns, smoke stacks, and fireplaces. The manufacturing sector, however, uses refractory materials on a much larger scale and requires the proper care while being serviced yearly for boiler inspections.

Refractory Services and Installation

At American Refractories, we are dedicated to determining the most appropriate and economical refractory solution for your particular situation. We are proud to offer heat-resistant refractory linings with premium insulation value, higher resistance to thermal shock, faster heating and cooling of the combustion chamber, and greater overall efficiency.

First, we identify the refractory liner most suitable for an application. To do so, we assess the frequency of on-off cycling, insulation value, jacket appearance, thermal shock, exposure to chemical agents, catalytic heat, and combustion efficiency.

Our ACSI Refractory engineers can also provide the custom molds that are required for your total solution. These are made by mixing high-temperature ceramic materials to form burner blocks that withstand up to 2100°F. We also consider the weight of the lining, accurately identifying it across a weight spectrum to prevent potential cracking due to stress. We have the industry expertise to make certain all of your refractory requirements are handled to your full satisfaction.

We are proud to say that ACSI Mechanical Group’s refractory services often add years to a boiler’s operation.
