I. Introduction to Refractory Materials Refractory materials are inorganic non-metallic materials that maintain strength and stability at high temperatures. They are widely used in metallurgy, cement, power, petrochemical, and environmental protection industries. Main types include high-alumina bricks, clay bricks, refractory castables, refractory cement, insulating bricks, … Lire la suite

During the manufacturing process of laser cutting machines, the high-temperature areas and heat treatment stages of the equipment place extremely high demands on refractory materials. To ensure long-term and stable operation of the equipment, mullite insulation bricks or high-alumina bricks are often used as thermal … Lire la suite

In the lining construction of industrial furnaces and high-temperature equipment, castables are widely used due to their ease of construction, good integrity, and durability. Refractory castables and insulating castables are two common types. Although their names are similar and they are often used together in … Lire la suite

The typical refractory materials required for different zones of a lime kiln are as follows: Kiln Zone Working Conditions Common Refractories Remarks Kiln Head / Kiln Tail (High-Temperature Erosion Zone) Direct flame impact, frequent temperature fluctuations – High alumina bricks (Al₂O₃ ≥ 60%) – Magnesia-chrome … Lire la suite

Refractory bricks and refractory castables are the two most common refractory materials used in the design and operation of high-temperature industrial furnaces. They have different performance characteristics and applications, and choosing the right one directly impacts the furnace’s lifespan and operating costs. 1. The Difference … Lire la suite
