Lightweight Silica Brick Refractory Brick Production Process - Xinhongji Refractory

Silica bricks (also called silica refractory bricks or silicate fire bricks) are made of silica sand material, and the content of SiO2 is more than 94%. And Al2O3 is lower than 1.0%, apparent porosity is under 22%. Silica bricks belong to acid refractory bricks, which have the excellent ability to resist acid slag and acid erosion. Silica bricks are also featured with highly dense characteristics and good heat conduction. The refractoriness can reach the most 1730°C. they are ideal high-temperature furnace construction materials. Silica bricks are normally used in the iron & steel industry, and the super grade will be the necessary refractories in the glass industry. The silica refractories are manufactured as multiple asymmetric shapes, which are normally keyed or interlocked with each other by means of tongues and grooves. Silica bricks are widely used in the bottom and walls of coke ovens. 🔥 Hot sale! silica bricks 📣 Contact now: sales@ a
