The Advantages of ROTALOCK Refractory Anchors, The Most Versatile Anchor System From TFL

Mar 01, 2021

 Rotalock Anchors Can Reduce Stress On Refractory Linings And Improve Worksite Safety

TFL offers a wide variety of custom refractory anchors professionally engineered in a variety of alloys and sizes. One of our more versatile anchors is the Rotalock anchor system, which features an innovative “break-away” design. This break-away feature reduces stress on refractory linings by allowing for slight movement to occur, while still holding the lining tight to the wall. Unlike other break-away anchors, the impressive friction lock feature of the Rotalock anchor means no tack-welding is required. Read more about the advantages of the Rotalock Anchor System below:

  Major Benefits of The Rotalock Anchor System: 

  • Break-away design allows for movement, reducing stresses in the lining
  • V-anchors can be installed after backup linings are placed, ensuring the hotface anchors are clean and undamaged
  • Since V-anchors can be installed just before hotface lining is placed, workers are not exposed to a dangerous array of anchor legs – worksite safety is improved
  • Rotalock bases can often be made from carbon steel, reducing anchor costs
  • Rotalock bases can often be reused on future repair jobs, greatly reducing maintenance costs down the line

Rotalock anchors can be configured for single component linings or multi-component linings depending on your application. Our team of refractory experts are available to answer questions and will make sure your anchors are manufactured to your specifications, in the right quantities, and delivered on time.

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.
