CA50 A700 refractory cement is a high-alumina binder made from bauxite and limestone. Its core application is as a bonding system for formulating high-performance monolithic refractories. Compared to ordinary building cement, it imparts superior volume stability and mechanical properties to refractories at high temperatures. Its … 続きを読む

Magnesia (MgO) bricks are essential refractory materials for reverberatory furnaces in non-ferrous metal smelting due to their high melting point (>2800°C) and excellent resistance to basic slag corrosion. Sidewall Applications: Below the slag line, where molten slag attacks aggressively, magnesia-chrome bricks are preferred for their resistance … 続きを読む

Mercury-lithium recovery furnaces are specialized heat treatment equipment used to process hazardous waste containing mercury and lithium. They are primarily used for the resource recovery of materials such as waste lithium batteries, mercury-containing catalysts, chemical residues, metallurgical byproducts, and laboratory waste. Through controlled heating, mercury … 続きを読む

The refractory bricks commonly used in Steam Reformers are primarily alumina-silicon based materials, with key requirements being low iron content, resistance to reduction, and long-term high-temperature stability. 1️⃣ High-alumina refractory bricks (Al₂O₃ 60–80%): The most widely used type, applied to the radiant furnace walls, furnace … 続きを読む

Electric arc furnaces (EAFs) are core equipment in modern short-process steelmaking, and their lining materials directly affect furnace life, energy consumption, and production stability. Magnesia bricks, due to their excellent high-temperature performance and resistance to chemical erosion, have become an indispensable key refractory material in … 続きを読む

What are Ceramic Foam Filter Sheets? Ceramic foam filter sheets are porous ceramic materials made primarily from alumina, silicon carbide, or zirconium oxide. They possess a three-dimensional, interconnected open-pore structure, resembling a sponge in appearance. Their porosity is typically between 75% and 90%, with uniform … 続きを読む

The boiler ash chamber is a critical component of the boiler system, subjected to high temperatures, ash erosion, and frequent thermal cycles. Therefore, it demands high strength, wear resistance, and thermal stability from refractory materials. Using refractory castables for solid brick forming is a mature … 続きを読む

High alumina cement (HAC), also known as calcium aluminate cement, is a specialized hydraulic binder made from alumina-rich raw materials. With an alumina content typically between 40% and 80%, it offers outstanding heat resistance, rapid strength development, and strong durability in corrosive environments. These characteristics … 続きを読む
