Flue Wall Crown and Port Blocks

Pre-cast crown and port blocks are mounted on carbon bake furnace flue walls. Originally crowns tended to be shallow and cast in one material. Over the years deeper crowns have been found to increase flue wall stability. Deeper crowns permit the use of multiple layers of refractory and insulating concretes that improve thermal performance. Refraco continually improves its flue wall crown and port blocks designs. Today, we offer deep, multilayer crowns with well designed anchor systems that provide high performance blocks at very competitive prices.
