The THERMA-PANEL system is for use in car-bottom furnace hearth refractory linings. The shapes are cast from a special type of refractory material with high impact strength and outstanding resistance to thermal shock damage. The unique geometry of the shapes provides for a stable structure while allowing no straight through joints in the lining. Because of the independent nature of the interlocking panels, stresses are broken up and cracking is minimized. For future repairs, spare shapes can be kept on hand. Repairs can also be easily isolated to the replacement of only those shapes that may be damaged. Another added benefit of the THERMA-PANEL system is the elimination of an initial bake out of the lining, since the shapes are pre-fired in TFL’s digitally controlled furnace.
I want to hear from you. Tell me how we can improve.
