Anchors

HTT.edu ·

2025/12/02

In this episode of HTT.edu, we dig into the unsung hardware that keeps monolithic refractories where they belong: anchors. Listen in as we break down metallic anchors and why their alloy, shape, and spacing matter; take a look at classic bottle anchors and what makes them the go-to choice for castables; and wrap up with brick anchors and how they tie brick linings into shells without compromising expansion. It’s a quick tour of the little pieces that make a big difference in keeping hot...

Physical Performance of Refractories

HTT.edu ·

2025/11/11

MOR, CCS, PLC... There are so many acronyms in the refractory industry when it comes to the properties that we depend on. Beyond understanding what those acronyms mean, we also need to understand what they mean. This episode of HTT.edu aims to do just that. We look at the various tests that can be done to qualify refractory performance and what we can learn from those tests. Listen in and get a better sense of what your refractories are capable of. If you have any questions or would like...

Plastics - Installation

HTT.edu ·

2025/11/04

When it comes to refractory plastics, you can get a surprising amount of work done without knowing the first thing about the limitations of the material. More difficult and robust jobs call for a more detailed level of understanding, but that only makes up a small subset of those using this category of material. This episode, HTT.edu will look at the tools, jobsite, and installation procedure for installing refractory plastics in various applications. If you have any questions or would like t...

Thermal Conductivity and Heat Transfer

HTT.edu ·

2025/10/21

The main role of refractories is to contain the fires of industry. While there are many destructive mechanisms that refractories resist, their first job is to contain all that heat. This episode, we will be talking about how refractories dissipate heat through the thickness of our lining, taking a 2500F inside down to a 250F shell temperature, keeping our workers safe, keeping our costs down and keeping our furnaces efficient. If you have any questions or would like to discuss something in mo...

Thermal Expansion

HTT.edu ·

2025/10/14

In high temperature, refractory containing industries, it's important to understand what changes occur to your lining throughout the temperatures the furnace experiences. One such change is that of expansion. Listen in to learn about reversible thermal expansion and permanent linear change and what that means for furnace function and design.

Not many refractory resources will give you more than five words on mortar technology, so HTT.edu is proud to give you an entire episode on the topic. A critical part of any brick construction, mortars are more than just a simplified monolithic. Join in to hear about the complex diversity of mortar and mortar selection and why they're so much more than the fat joints you see in a brick house.

Bricks 101

HTT.edu ·

2025/09/23

Finally getting out of episodes entirely dedicated to monolithics, join in to hear a little bit about a specialty of HWI, a member of Calderys: bricks. While equally as complicated as monolithics, the challenge in brick making is almost entirely in the hands of the manufacturer. Tooling, pressing, firing and stocking are major hurdles to good brickmaking, but once the brick are in your hands, you can trust in the quality of the product.

Monolithics 201 - Dryout

HTT.edu ·

2025/09/16

In possibly the most complicated part of using a high performance refractory material, we need to carefully bring the furnace up to temperature to dry out the refractory and remove all that water that we put in. Listen in to find out how we do that, why these processes are so complicated and how the basics can help you gain better control of the high temperature process you can't see.

Monolithics 201 - The Cure

HTT.edu ·

2025/09/09

After placing monolithic refractory in the lining/forms, you need to wait 24 hours for it to cure before beginning the dryout. But why are we doing that? What's happening to the material during this time and what are we expected to do with it? Listen in to hear about the mineralogical activity going on within the material during this 24 hour period and why it's important.
