Cordierite-mullite kiln furniture (saggers, shelves, posts and beams) combines low thermal expansion with high refractoriness under load, offering excellent thermal shock resistance and long service life for ceramic, electronic ceramic and magnetic material kilns.
Slide gate plate is the core functional refractory of ladle and tundish slide gate systems, offering high strength, high density, excellent erosion and thermal shock resistance for precise molten steel flow control.
Ladle purge plug (corundum-spinel type) blowing argon at ladle bottom features high and stable permeability, high strength, excellent erosion and thermal shock resistance, homogenizing steel composition and removing inclusions in ladle refining.
Ladle shrouds and submerged entry nozzles are key functional refractories in continuous casting. They protect the steel stream against reoxidation and control mould flow. Alumina-carbon body with ZrO2 slag line resists slag, prevents clogging and sustains multi-heat sequences.
Integral stopper rod is the core flow-control refractory in the continuous casting tundish. Alumina-carbon or magnesia-carbon grades resist thermal shock and erosion with a durable slag line. Argon-blowing structures and rod-head shapes are customized for stable multi-heat flow control.
Si3N4 bonded SiC brick is made of high-purity silicon carbide with in-situ formed silicon nitride bond, featuring excellent thermal shock resistance, high strength, high thermal conductivity and oxidation resistance for blast furnace tuyeres, aluminum cell sidewalls and kiln furniture.
Silicon carbide brick (SiC≥85%, refractoriness ≥1900℃, CCS≥120MPa) offers high thermal conductivity, extreme wear resistance, thermal-shock resistance and molten-salt resistance—preferred for waste incineration and hot abrasion duties.
Fused-cast AZS block (Al₂O₃≥48%, ZrO₂≥32%, bulk density ≥3.60 g/cm³, porosity ≤2%) is cast from the melt to near-zero porosity, giving outstanding resistance to glass-melt erosion and scouring.
Zirconia brick (ZrO₂≥95%, 2300℃ max, bulk density ≥5.20 g/cm³) with stabilized high-purity zirconia resists ultra-high-temperature melts and atmospheres—among the highest-temperature oxide refractories.
Checker brick with porous/honeycomb custom holes (Al₂O₃ 45-75%, RUL ≥1500℃) maximizes specific surface area for efficient regenerative heat exchange—the core element of hot stove checkers.
Refractory balls (Al₂O₃ 55-99%, Φ25/40/50/60/75mm, crush load ≥40kN/ball, refractoriness ≥1790℃) maximize specific surface for efficient regenerative exchange. For regenerators of pebble-type hot blast stoves and regenerative reheating furnaces, and petrochemical regenerative air preheaters.
Custom special-shaped bricks cover fireclay, high-alumina, mullite, corundum, silica and magnesia grades with ±1mm tolerance and up to 80kg per piece, produced from drawings by die pressing or casting.
Refractory precast blocks are factory-cast, cured and fired to drawings in castable, corundum and other grades with ±2mm accuracy. Crane-installed for short outage and consistent quality—key to fast maintenance.
