Product Specification of High Quality Best Price Accurate Size Refractory Silica Bricks
The silica bricks are the main fire-resistant material of coke oven. In order to keep its high quality,we use the high purety quatz with the multistage batching and best grain matching, our semi-manufactured goods are produced by the pressing machine.

The bottom,Wall and top bricks are produced by 500tons bricks pressing machine. Every semi-manufactured and finished product-s are examined according to the national standard and marked it according to the tolerance.

silica bricks are used for coke and annealing furnace, covering the walls of the furnaces, in high heat areas of melting furnaces.

Features And Advantages of Refractory Silica Brick
1) Silicon oxide is above 95%.
2) Good acid erosion resistance.
3) High softening point with temperature.
4) No shrink in burn repeatedly.
5) Temperature of refractoriness under load is above 1650º C Stable Capability, High Quality, Excellent Service, Competitive price is the most important advantage of our products.

Application of Silica Refractory Bricks
Silica refractory bricks are widely used in industries where high temperatures and corrosive conditions are present, such as:
Metallurgy: Silica bricks line the walls of furnaces and converters in steelmaking plants, where they withstand the intense heat and chemical reactions involved in the production of steel.
Glassmaking: They are used in the construction of glass melting tanks and furnaces due to their ability to resist the high temperatures required for glass production and their resistance to the corrosive effects of molten glass.
Ceramics: Silica bricks are employed in kilns and other ceramic manufacturing equipment to provide thermal insulation and resistance to the harsh conditions present during firing processes.
Petrochemicals: Refractory linings in petrochemical plants, such as those found in cracking units and reformers, utilize silica bricks to withstand the extreme temperatures and corrosive environments encountered during the production of various petrochemical products.
Power generation: Silica refractory bricks are used in the construction of boilers and furnaces in power plants to withstand the high temperatures generated during the combustion of fuels and to provide insulation for efficient energy production.
