Low-creep high-alumina brick with Al₂O₃≥75% and creep rate ≤0.8% (1550℃×50h), RUL ≥1550℃. Minimal deformation under long-term hot load, engineered for load-bearing hot stove domes and walls.
| Al₂O₃ Content | ≥75% |
|---|---|
| RUL (0.2MPa) | ≥1550℃ |
| Creep (1550℃×50h) | ≤0.8% |
| CCS | ≥70 MPa |
Low-creep high-alumina bricks are designed for hot blast stoves with Al₂O₃ ≥75%, load softening point ≥1550℃ and creep ≤0.8% (1550℃×50h). Minimal creep under long-term hot load restrains dome sagging and joint opening for a long, stable stove campaign. It is Henan Songrui's professional grade for hot blast stove domes and load-bearing walls.
Prefer low-creep grade for stove domes and hot load-bearing zones; paired with checker bricks it achieves overall stove longevity. LZ-55/LZ-65 control cost in cooler zones.
Lay per hot blast stove specifications with strict joint control; selection and heat-up curve advice provided. Complete package solutions available.

Low-creep high-alumina brick features minimal high-temperature creep:
Very low high-temperature creep keeps dimensions stable, ideal for hot blast stove domes and mixers.
Domes, hot walls and hot checkers, extending stove life and reducing major repairs.
About 1550℃ max, recommended long-term ≤1500℃ to maintain low creep.

High-alumina brick LZ-55 (Al₂O₃≥55%) with refractoriness ≥1770℃ offers dense structure, wear resistance against gas scouring and combined cold/hot strength—one of the most widely used shaped refractories.
High-alumina brick LZ-65 (Al₂O₃≥65%, refractoriness ≥1790℃) has a higher corundum/mullite phase ratio for stronger slag resistance, higher temperature rating and better hot load-bearing capacity.
Phosphate-bonded high-alumina brick (Al₂O₃≥75%, refractoriness ≥1770℃) avoids high-temperature firing for energy saving, hardening further in service as temperature rises. Cost-effective with good thermal-shock resistance.
Spalling-resistant high-alumina brick introduces ZrO₂ (3-6%) for transformation and microcrack toughening. Al₂O₃≥70%, thermal-shock stability ≥15 cycles, greatly improved resistance to structural spalling under frequent temperature cycling.
