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...

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 aims to reveal that all that operation is just the tip of the iceberg. By understanding what plastics are and how they're designed, you can do more with this pliable and useful category of products.

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 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
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.

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, 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
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. If you have any questions or would like to discuss somet...

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 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
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.

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 considerations on placing refractory necessary for getting the most out of your castable materials.

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 important for optimizing our refractory properties. Listen in to find out what makes water good water and why are refractory suppliers so adamant about using the right amount of water?

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 plastics. What are the differences between all these installation methods and how do I choose where to use which? Listen in and understand that castables are not just castables and there's nuance to everything. If you have any questions or would like to discuss something in more detail, reach out to use ...

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 every 60% alumina low cement castable the same, despite their similarities on the datasheet, and why an ultra-low cement castable might be better for your operation than a convential cement castable.
