Insulating firebricks - Maximizing energy savings in iron and steel applications through product selection

摘要

Insulating Firebricks are manufactured by various techniques (casting, slinger, extrusion, foaming, pressing, etc.) and the brick chemistries and microstructures produced can be very different. This leads to a wide variety of thermal conductivities available within products of the same temperature rating and results in a wide variation in the ability of the different types of IFBs to control energy loss from an application. This article reports the findings of a study by Morgan Thermal Ceramics to quantify the differences in energy usage that can be achieved with the three main types of IFB available on the market (cast, slinger and extruded) within Class 23 and Class 26 IFBs.
