China 2021 Good Quality Silica Refractory Brick - Industrial Refractory Bricks Sillimanite Brick For Tunnel Kiln – Rongsheng factory and manufacturers | Rongsheng

Sillimanite bricks are a kind of high quality refractory brick with high refractoriness of 1770~1830℃ and high refractoriness under load of 1500~1650℃, whose physical and chemical property is better than high alumina bricks. Sillimanite transforms into mullite and free silicon dioxide after high temperature firing. Sillimanite refractory bricks generally adopt manufacturing process of high temperature firing and mud mix pouring process.

Properties of Sillimanite Fire Brick

• Good thermal shock resistance,
• High dense structure,
• Slag corrosion resistance,
• Good thermal conductivity,
• Good thermal stability,
• Heat exchanger,
• High structural strength,
• Low high temperature creep.

Composition of Sillimanite Fire Brick

Sillimanite fire brick belongs to neutral refractory. Sillimanite brick is made of sillimante minerals, which can transform into mullite and free silica after high temperature firing. sillimanite refractory brick is produced by the methods of high temperature firing and casting.

Sillimanite Fire Brick Manufacturing Process

Sillimanite bricks are manufactured with main raw material of sillimanite, sillimanite is a kind of quality refractory raw materials and used to produce high alumina brick with low creep, high refractoriness under load, high heat shock and micro-expansive, and furnace top. sillimanite can be transformed into mullite and free silicon dioxide through high temperature firing. sillimanite refractory bricks physical and chemical property are better than high alumina bricks. Sillimanite fire brick refractoriness is 1770~1830 ℃ and apparent initial softening temperature is 1500~1650℃.
