What Is High Alumina Refractory Gunning Mix
High alumina gunning mix is an unshaped refractory material produced from high‑purity bauxite aggregate, fine powder, special binder and functional additives. It is applied by pneumatic spraying equipment for hot repair and patching of high‑temperature furnace linings. Unlike refractory castables, it needs no formwork. It can be sprayed directly onto existing refractory surfaces to build a dense, strong protective layer, suitable for both hot and cold repair of thermal industrial equipment.
Core Advantages of High Alumina Gunning Mix
Our high alumina gunning mix boasts high refractoriness, great thermal shock resistance and superior slag erosion resistance. It features a low rebound rate during spraying, strong bonding strength and fast hardening after construction. After curing, the lining stays structurally stable under continuous high temperatures, effectively slowing down wear and thermal corrosion. It minimizes furnace downtime, lowers maintenance costs and prolongs lining service life. We supply multiple grades with different Al₂O₃ content to satisfy various working temperature demands.
Wide Industrial Application Scenarios
This gunning mix is widely used in metallurgy, cement, power, forging and waste treatment industries. In steel mills, it repairs electric arc furnaces, blast furnaces, ladles and tundish linings. For cement plants, it fixes worn zones on rotary kiln transition sections and preheater linings. It also works for power station boiler linings, forging heating furnaces, soaking pits, waste incinerators and partial glass furnace patching. It quickly repairs cracked, eroded or spalled refractory areas without lengthy shutdowns to keep your production running steadily.
