Direct gunning operation at temperatures up to 1200℃; no furnace shutdown or cooling required.
Mainly repairs wear, spalling and holes on the linings of converters, electric arc furnaces, steel ladles and refining furnaces.
Single repair takes only 30–60 minutes, far more efficient than cold repair.
Dry refractory materials are fed from hopper, conveyed via rotor and compressed air through hoses, mixed with water at the nozzle, and then sprayed onto furnace walls at high velocity.
The formed refractory layer features high density, uniformity and mechanical strength, with excellent resistance to corrosion and thermal shock.
Evens out lining erosion and prevents premature local damage.
Cuts down major overhaul shutdowns and improves effective steelmaking operating time.
Reduces refractory consumption per ton of steel and increases steel output.
