Product Description

KERUI Factory Direct Price Silica Checker Bricks for Hot Blast Furnace

Silica brick is an acidic refractory material primarily composed of flake quartz, crystalline quartz, and small amounts of residual quartz and glass phase. It possesses excellent resistance to acid slag erosion and exhibits a high load softening temperature ranging from 1640 to 1670°C. Furthermore, it maintains a relatively stable volume during long-term usage at high temperatures.
Our Silica Bricks are meticulously crafted from premium-quality silica materials, carefully selected to ensure superior purity and consistency. The production process involves precise blending, shaping, and high-temperature firing, resulting in durable and reliable bricks. With state-of-the-art manufacturing facilities, we guarantee consistent quality and meet the stringent demands of various industries.
