Slag and Refractory Characterization.

MTI’s new high-temperature Deltech furnace significantly enhances our abilities to examine slag-melting behavior and slag refractory interactions. For example, this system will enable us to assist in the development of synthetic formulations as well as refractory corrosion.

The interaction of slag with refractory materials is determined using cup tests at temperatures up to 1700°C in reducing or oxidizing atmospheres. The cup and slag materials are analyzed using SEM techniques to determine penetration and reaction of slag with refractory materials.
