Customer：Ironmaking plant in Hebei (2500 m³ BF stoves)Location：Handan, Hebei
1Challenge
After long operation above 1300°C the checker bricks crept and cracked, blocking flues and destabilising blast temperature. A precise drawing-based brick package and reliable delivery were required.
2Solution
Low-creep high-alumina brick was used for the high-temperature zone walls and checkers, silica brick for the medium zone. Shaped checker tiles were CNC-machined to the stove drawings, crated with numbering, and supplied with high-alumina mortar and bricklaying guidance.
3Result
Blast temperature became noticeably more stable and the checkers are designed to last a full campaign. The customer was satisfied with shape precision and complete delivery, and has agreed on second-phase stove maintenance cooperation.
