Eight Common Refractory Materials For Heat Treatment Furnaces And Their Applications
Heat treatment furnaces commonly use refractory materials such as fireclay bricks, high alumina bricks, anti-carburization bricks, refractory concrete, silicon carbide products, various aluminum silicate refractory fibers, and refractory coatings. Among these, fireclay bricks are the most widely used in heat treatment furnaces. PART 01: Fireclay Bricks Fireclay bricks are primarily made from refractory clay and kaolin. Their chemical composition includes Al₂O₃ (30%-40% by mass), SiO₂ (50%-65% by mass), and other metal oxides. Ordinary fireclay bricks are classified as weakly acidic…
