FAQs

How are refractory bricks classified by material?

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.

Can special-shaped bricks be made per our drawings?

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.

What are refractory precasts and what is the lead time?

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.

How to choose between high-alumina and fireclay bricks?

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.
