Application of Magnesia-Carbon Bricks in the Steel And Metallurgy Industry

Application of Magnesia-Carbon Bricks in the Steel And Metallurgy Industry

Our Blog
Use of MgO-C Bricks in Refining Ladles and Steel Ladles MgO-C bricks are widely used in refining ladles and steel ladles, primarily in the freeboard and slag line areas. These areas require refractory materials with high resistance to high temperatures, thermal shock, and slag erosion. Traditionally, magnesia-chrome refractories were used for these sections, but due to environmental concerns over chromium pollution, they have been largely replaced by magnesia-carbon bricks. During the preheating process, the MgO-C bricks in new ladles undergo…

Eight Common Refractory Materials For Heat Treatment Furnaces And Their Applications

Eight Common Refractory Materials For Heat Treatment Furnaces And Their Applications

Our Blog
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…

Durable And Energy-Saving Ultra-Low Cement Refractory Castables

Our Blog
Durable And Energy-Saving Ultra-Low Cement Refractory Castables Ultra-low cement refractory castable is an important refractory material. Below is a detailed introduction: 1. Definition and Characteristics Ultra-low cement refractory castable refers to a type of refractory castable in which the amount of calcium aluminate cement is significantly reduced, typically with a CaO content of less than 1%. By reducing the amount of cement and introducing additives such as ultra-fine powders, this material enhances refractoriness, high-temperature strength, slag resistance, and reduces porosity.…
