Silica brick

Silica bricks are often used to construct the superstructure and main crown of small and medium-sized glass melting furnaces. Silica brick has excellent properties and its composition is similar to that of glass melt.

Other name: Silica brick, Dinas brick

Model Number: HCR 96A,HCR 96B,HCR 95A,HCR 95B

Certification: ISO9001-14001

Silica Brick

Description:

Silica brick is an acid refractory material with good resistance to acid slag erosion. Its refractoriness under load is as high as 1640 ～ 1670 ℃, and the volume is relatively stable under high temperature for a long time. Silica bricks have poor thermal stability at low temperatures. It will be heated and cooled slowly below 800°C to avoid cracks during use. Therefore, it is not suitable for use in kilns with sudden temperature changes below 800 ℃.

Advantage:

High temperature volume stability, strong resistance to acid slag erosion

Application:

Coke oven, soaking furnace, glass melting furnace, hot blast stove
