Ceramic Fiber Products


ur experience covers most furnaces types including boilers, heat treat, metal melting, refining, laboratory, kilns, ovens, crucible, forging, reduction or refining. We can engineer refractory linings for gas fired, electric fired, induction or radiant heated. We have heat flow programs that can design refractory combinations for performance as well as fuel savings. We are also familiar with conditions that degrade refractory performance such as chemical attack, abrasion, flame impingement or thermal shock and can assist in designing linings that resist these problems.
