Steel & Power
Sinter plant, coal handling, ash and slag transport — high temperature plus high abrasion, which is where most liners get specified wrongly.
Steel and power plants combine the two conditions that are hardest on linings: abrasive bulk material and sustained heat. A layout that works at ambient temperature in a cement plant will often fail here — not because the tile is soft, but because the fixings, the backing adhesive or the steel shell give up first.
How wear actually happens
- Sinter plant chutes and bunkers. Hot sinter with sharp edges at 150–400 °C. Impact is severe and the liner must be mechanically fixed, never glued.
- Coal handling. High tonnage, moderate particle size, but silica content makes it genuinely abrasive. Long belts mean large lined areas.
- Ash and slag transport. Abrasive and often corrosive, with wet and dry zones in the same system.
- Flue gas ducts. Erosion by fly ash at high velocity, usually concentrated on the outer radius of bends.
- Bunker and silo linings. Combined sliding wear and bridging problems; ceramic linings improve flow as well as life.
What we normally supply
- AL-95 tiles, 25–50 mm, weld-in studs, for sinter and coal chutes
- AL-99 tiles for high-temperature zones and areas with condensate corrosion
- AL-99.7 for furnace furniture and continuous duty above 1,400 °C
- Lining bricks for bunker walls and thick-section applications
- Ceramic-lined pipe for ash slurry and pneumatic conveying
- Alumina nozzles and tubes for burners, lances and pneumatic injection
Typical grade and thickness
| Application | Grade | Thickness / size | Notes |
|---|---|---|---|
| Sinter chute | AL-95 | 30–50 mm | Mechanical fixing only; check the shell for distortion before relining. |
| Coal bunker | AL-92 / 95 | 20–30 mm | Wall-mounted tiles also improve flow and reduce bridging. |
| Ash slurry line | AL-99 | 12–25 mm | Corrosion plus abrasion — low porosity grade. |
| Flue gas duct bend | AL-99 | 10–20 mm | Study the gas velocity; a small radius change often beats a thicker tile. |
| Burner nozzle | AL-99 / 99.7 | by drawing | Thermal shock resistance dominates the design. |
