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.
Silica brick with SiO₂≥94%, refractoriness ≥1690℃ and RUL ≥1620℃ shows no high-temperature shrinkage, stable under long-term load and resistant to acid slag and atmospheres—the recommended choice for coke ovens.
Magnesia-carbon brick bonds magnesia with graphite (MgO≥76%, C 14-18%, 1750℃ max). Carbon does not wet slag, giving exceptional slag-line erosion resistance and thermal-shock stability far better than burned magnesia brick.
Mullite brick with mullite as the main phase (Al₂O₃≥75%, refractoriness ≥1850℃, RUL ≥1650℃) offers high-temperature volume stability with excellent thermal-shock and creep resistance.

Answers on materials, customization and lead times
By material: fireclay, high-alumina, silica, magnesia (MgO, MgO-C, magnesia-spinel etc.), corundum, mullite, silicon carbide and special bricks like fused-cast AZS. Each grade has different temperature ratings and erosion resistance — selection depends on furnace type, temperature and media.
Yes. With professional mold design and forming capability, we make custom special-shaped bricks in alumina, fireclay, mullite and corundum grades with ±1mm tolerance, supporting small trial runs and mass production. Drawings or samples are welcome.
Refractory precasts are pre-formed components cast from monolithic refractories per furnace drawings, lifted and assembled on site for fast, reliable relines. Typical lead time is 7-15 days including curing and pre-firing; complex large items are assessed case by case.
Fireclay bricks (Al₂O₃≈40%) have good thermal shock resistance and economy, suitable below 1300℃ and for thermal cycling zones; high-alumina bricks (Al₂O₃ 55%-80%) serve above 1400℃ and load-bearing zones with higher strength. They are often combined by kiln zone.
