► Description:

LZ-3ER-GV Refractory spraying machine is a multifunctional rotor type machine for dry spraying and conveying. The materials that can be sprayed and conveyed are refractory materials, castable, concrete, mortar, sand, pea gravel and crushed stone.

Compared with traditional gunning machine, LZ-3ER-GV gunning machine has the advantages of being lighter and more compact. By changing the rotor of different sizes and adjusting the motor speed, the theoretical displacement range is 0.5~3m3/h, which can better meet the needs of customers. 

► Application:

LZ-3ER-GV Refractory spraying machine is suitable for localized repair, preventive maintenance and restoration of worn refractory linings in high-temperature furnaces and metallurgical vessels.

Refractory gunning material can be sprayed directly onto damaged or eroded lining areas to rebuild the required thickness and protect the original refractory structure. The equipment is especially useful for repairing vertical, curved, overhead and difficult-to-access furnace surfaces.

Typical refractory lining repair applications include:

Furnace sidewall repair

Refractory hot spot repair

Slag line maintenance

Furnace bottom and lower wall repair

Upper furnace wall repair

Furnace roof refractory restoration

Charging area repair

Tapping area lining maintenance

Burner surrounding area repair

Oxygen jet impact zone repair

Tuyere area refractory repair

Local crack and erosion repair

Worn refractory surface restoration

Preventive lining maintenance

Emergency refractory repair

Hot refractory repair after tapping

Furnace shutdown maintenance

Partial lining reconstruction

Extension of refractory lining campaign life
