Kaifeng Datong Refractories supplies premium calcined alumina, fused spinel & thermal insulation materials for laser cutting, laser welding machinery. Widely applied in sheet metal, elevator, shipbuilding, food & pharmaceutical equipment manufacturing and all metal processing industries.
Facing rapid lining degradation in corrosive electrolytic cells, a major aluminum smelter adopted our composite refractory solution—boosting corrosion resistance, extending overhaul cycles by 40%, and cutting O&M costs. Discover how.
Steel manufacturer faced high energy costs & lining failure from poor insulation. Switched to high-purity alumina hollow balls—cut heat loss, extended lining life, boosted energy efficiency. Discover the refractory upgrade that transformed metallurgical furnace performance.
Metallurgical client faced high heat loss & unstable smelting due to dense, inefficient insulation. Deployed high-purity alumina hollow balls as refractory aggregate—cut energy use 32%, lowered surface temps, extended lining life. See how we enable efficient high-temp operations.
Cement producer faced frequent hot repairs due to castable cracking & strength loss. Switched to high-purity calcium aluminate cement—cut demolding time, slashed hot repairs, and ensured stable high-temp strength. Discover how.
Glass manufacturer faced frequent shutdowns due to lining erosion. High-purity mullite refractories enhanced alkali & melt resistance, extending maintenance cycles and boosting continuous operation efficiency.
Ceramic manufacturer faced frequent kiln furniture failure due to thermal shock. Upgraded to high-purity white fused alumina—extended service life, cut replacements, and raised yield. Discover the refractory advantage.
