Refractory Tips: 5 Things Every Plant Manager Should Know

Jun 29, 2018

Refractories are a substantial investment, whether you’re managing a new construction or overseeing repair work. While refractory work might only be a small part of your construction project, the materials will protect your equipment, keep production online, and provide safety to your staff.


The cost of your refractory is far less than the value it will bring to your manufacturing plant.

Refractory Tips for Plant Managers

If refractory work is not the driving force of your plant, you may not have the level of expertise necessary to make decisions without help. Meeting with a reputable refractory expert can provide further insight and valuable advice. Here are 5 basic tips to help you in the meantime:

1) Refractories have different chemical compositions

  • Acidic refractories aren’t affected by acids and consist of acidic materials such as silica, alumina and fire clay. They are adversely affected by basic materials.
  • Neutral refractories are used when the slags need to be chemically stable to both acids and bases. Alumina, chromium, and carbon are often used in neutral refractories.
  • Basic refractories are used where the slags are basic. These are stable to alkaline materials but could react with acids. Magnesia is ubiquitous to basic refractories.

2) Extreme heat isn’t the only threat to your refractory

Refractories must not only withstand extreme heat but must also be resistant to the chemicals that are released during the manufacturing process. If the wrong refractory is used, the chemical interaction between the refractory and byproducts of the materials being heated can cause catastrophic failure.

3) A small crack can be a big problem

Refractory inspection and repair should be a routine part of your refractory management plan. A very small crack can let enough heat out to disrupt the chemical process of the heated materials or can allow heat to burn the refractory fiber acting as insulation. The results can be devastating.

4) Installation matters

Correct refractory installation is crucial to the productivity of your plant and the safety of employees. Don’t forget that your refractory will need time to cure. Include this in your installation plan, and don’t try to rush it or cut corners!

5) Customization is key

Refractories aren’t one size fits all.  Your plant may require custom refractory ingredient combinations explicitly created to provide the right protection for your application. Research and developments in the refractory industry have led to significant improvements and streamlining, but what works for one doesn’t work for all.

The Best Results

Whatever the size of your production facility, we can guide you through the process and show you how to find the best solution for your refractory application. You should never go into the process without an expert on your side.

Common Refractory Installation Mistakes
By Paul Fisher 17 May, 2023
When it comes to refractory installation, there are many things that can go wrong. Refractories are a crucial part of many industrial processes, and even small installation mistakes can lead to significant problems down the line. That’s why it’s essential to get it right the first time. Here is a look at some of the most common refractory installation mistakes and how to avoid them.

The East Bay Municipal Utility District (EBMUD) Wastewater Treatment Plant, located on the eastern shore of San Francisco Bay, provides service for an estimated 740,000 people in the greater Oakland, California area. In addition to traditional wastewater treatment, the plant also collects and treats solid waste from Bay Area food and animal processing facilities, restaurants, and wineries, diverting this waste stream away from landfills. The methane gas that is generated from the decomposition of this solid waste is then used internally as a renewable source of energy to help supply the treatment plant’s energy needs. When EBMUD began looking for a way to upgrade the failing brick refractory lining in their emergency digester gas flare structure, they turned to TFL, Incorporated. TFL developed an innovative precast refractory shape system that would offer dependable performance, structural integrity, and ease of installation. The unique system of floating wall panels is held in place using tongue-and-groove tieback shapes, bolted to the existing concrete structure. The individual panels in the system can absorb thermal and mechanical stresses independently. Given the location, potential seismic loading was also considered in the development of the system. The existing flare containment building is an oval-shaped concrete structure, with inside dimensions of 17’ wide by 47’ long. The refractory lined upper section of the structure is just over 21’ tall. The refractory wall thickness is 4-1/2”. A 2” air gap between the refractory wall and the concrete wall allows for airflow and ventilation. The refractory wall system consists of 514 precast shapes of four basic types, all manufactured in TFL’s Houston, Texas facility. The shapes were cast using Plicast HyMOR 3000 KK, a low-cement castable refractory manufactured by Plibrico Company. Stainless steel needle fibers were used for added reinforcement and to improve resistance to thermal shock and cracking. The shapes were fired to 1250o F prior to shipment, optimizing strengths and allowing the flare structure to be immediately operational, without the need for a field dry out of the refractory. NTK Construction, Inc. of San Francisco, California, was the installation contractor for EBMUD.

Over the years, the refractory industry has faced many challenges. Precast-shape technology has helped us overcome some of them. The technology is used across different industries to produce better results and save money. If you choose to work with refractory castables, the process needs to be perfect. The physical properties of the material are sometimes weakened during the manufacturing stages by several factors. It’s even more crucial to get it right when the complexity increases to secure the performance of the lining. You can take full advantage of a castable’s physical properties by casting precast shapes in a controlled environment with experts overseeing the whole process. When it comes to drying and firing a refractory castable, you want the best lining production. Precast shapes allow you to ensure that the bake-out schedule recommended by manufacturers is followed to the tee since they can be fired in a digitally-controlled furnace. The shapes can also be fired from all sides, reducing moisture and giving off a uniform look that diminishes cracks. Additionally, the lining is less susceptible to stress, and its performance is more predictable. Precast-shape technology has many benefits, and you should take advantage of it. If you’re ready to use precast shapes to optimize your next project, contact us today to learn more about how we can help you.
