Many times, gunite jobs are fairly straightforward; a refractory contractor can just “go in and blow” the gunite to install the refractory material. One of our recent gunite jobs, however, was quite complex. Our client was an Original Equipment Manufacturer (OEM) who had engineered and built two 40-foot steel “stack tops” that would be installed as the final piece on a…Read More ›

While refractory material is critical to protecting and maintaining the efficiency of your heat processing equipment (and more importantly, keeping your people safe!), it’s not always a priority for many of today’s industrial plant engineers and managers. Refractories are a complex field, heavy on both science and art. The idea that “mud is mud” is dangerous thinking that can end…Read More ›


The Hidden Cost of Corundum Growth in Aluminum Furnaces

If you have an aluminum furnace, you’re familiar with corundum. When molten aluminum oxidizes with oxygen in the atmosphere, corundum forms. And it’s dangerous, whether it’s forming in a melt furnace or in a holding furnace: When corundum forms inside of the furnace refractory, it expands and destroys the refractory lining and eventually the joints of the furnace. When corundum…Read More ›
