S1E23 Anchors
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…
S1E22 Refractory Ceramic Fiber
There are many different types of refractory bodies to consider when designing a refractory lining. Many of these have been covered in previous episode, but this episode will be looking at the…
S1E21 Technical Datasheets
With thousands of brands available globally, how am I supposed to differentiate between one brand name and another. Well, you could call your local sales rep, or you could look at their technical…
S1E20 Physical Performance of Refractories
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…
S1E19 Plastics - Installation
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…
S1E18 Plastics - Design and Properties
Refractory plastics are a product category that people often run on instinct. They're quite easy to use and can be applied to a wide variety of industries and applications. But this series on HTT.edu…
S1E17 Thermal Conductivity and Heat Transfer
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…
S1E16 Thermal Expansion
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…
S1E15 Where Refractories Are Used
As a respite from the many detailed fundamental episodes you've listened to thus far, this episode delves into the many different industries where refractories are used. Industries you might not have…
S1E14 Mortars
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,…
S1E13 Bricks 101
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,…
S1E12 Monolithics 201 - Dryout
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…
S1E11 Monolithics 201 - The Cure
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…
S1E10 Monolithics 201 - Placing
Placing refractories should be as easy as dumping refractory into the form, but there's enough nuance there to justify an entire episode on the topic. Listen in and hear about some important…
S1E9 Monolithics 201 - Water
Part three on our Monolithic Refractories 201 course isn't even about refractories, it's about the water that we're adding to mix our refractories. We can't treat all water the same and that's…
S1E8 Monolithics 201 - Mixing
In part 2 of the Monolithics 201 series, we move into the next step of casting, talking about mixers and proper mixing techniques. What mixer to use, the best mixing processes, and what you're seeing…
S1E7 Monolithics 201 - Storage
Pushing the limits for what fundamentals truly means, the Monolithics 201 series is geared to cover every aspect of the casting experience. This episode starts that overview the second the material…
S1E6 Monolithics 101 - Installation Methods
For Part 3 of the Monolithics 101 series, we're designing our vessel with a variety of different monolithic materials and trying to figure out where to use castables, gunnites, shotcretes and…
S1E5 Monolithics 101 - Cement Types and Levels
In Part 2 of our Monolithics 101 series, we're holding it together with different types of cement and how cement levels affect refractory properties. Listen in to hear about why you can't just treat…
