Lightweight silica brick is a high-performance refractory insulation material characterized by low density, high strength, excellent high-temperature resistance, and good thermal shock resistance.
Manufactured using high-purity silica raw materials and advanced process formulations, the product features a micro-porous structure formed through high-temperature sintering, providing an optimal balance between lightweight properties and durability.
Compared with traditional lightweight insulation bricks, it offers improved mechanical strength and thermal stability, making it an ideal solution for high-temperature applications.
It is widely used in semi-permanent and permanent lining layers of metallurgical equipment such as ladles and transfer pots, as well as in industrial furnaces including coke ovens and hot blast furnaces.
