HTT – Freeze Planes

This month on High Temperature Times™, Application Specialist Marc Palmisiano joins in to talk about the not-so-cold science behind freeze planes. When designing and operating aluminum furnaces, understanding freeze planes and where they should be in your refractory lining is critical to getting the best performance out of your refractory. This is especially important in these days of running furnaces harder, while also being more thermally efficient. One tool great for calculating freeze planes is HWI’s Heat Transfer Tool.
