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.

MgO-C bricks combine magnesia's high refractoriness with carbon's thermal conductivity and non-wettability, giving strong slag resistance and thermal shock stability — mainly for converter linings, EAF hot spots and ladle slag lines.

Insulating bricks have low strength and poor erosion resistance, so they normally serve as back-up insulation behind the working lining; they may face the process only in low-wear, slag-free low-temperature zones. We provide composite lining designs.
