Other Shapes of Silica Bricks
In addition to standard straight bricks, we also offer bricks in a variety of shapes, including special-shaped bricks, checkered bricks, ax bricks, anchor bricks, composite bricks, universal arc bricks, curved bricks, and so on.
Applications of Silica Fire Brick
| Metallurgy & Steel Industry | Hot blast furnaces, electric arc furnaces, converters, and other high-temperature smelting equipment. |
| Glass Industry | Furnace crowns, flow channels, walls of glass-melting furnaces—resistant to glass melt erosion. |
| Coke Oven Equipment | Carbonization chambers, combustion chamber walls—high thermal stability and long service life. |
| Chemical (including Petrochemical) Industry | Cracking furnaces, heating furnaces, reactors in acidic/alkaline high-temperature environments. |
| Cement & Fertilizer Industry | Rotary kilns, preheaters, fertilizer reaction vessels—endure high temperatures and corrosive environments. |
| Ceramic Industry | Tunnel kilns and general ceramic kiln linings; excellent thermal shock resistance and high‑temperature stability. |
| Power & Boiler Plants | Furnace bodies, boiler linings, chimney structures in thermal power applications. |
| Incineration Facilities | High-temperature linings inside waste incinerators—resist flame, heat, and chemical erosion. |
