The Converter Refractory Hot Repair Gunning Machine is designed for high-temperature maintenance of refractory linings in BOF converters and other steelmaking vessels. It sprays dry or semi-dry refractory repair material onto worn areas, helping restore lining thickness, extend converter service life and reduce shutdown time.
Main applications include:
BOF converter lining hot repair
Converter slag-line maintenance
Charging-side refractory repair
Tapping-side lining restoration
Converter mouth and cone repair
Trunnion-area refractory maintenance
Converter bottom and furnace-wall repair
Local repair of cracked, eroded or worn linings
High-temperature refractory spraying in steel plants
Preventive maintenance between major relining operations
Application Description
This refractory gunning machine is widely used in iron and steel plants for rapid hot repair of converter linings. It can accurately deliver refractory material to high-wear sections such as the slag line, charging side, tapping area, furnace wall and converter mouth. Regular gunning repair helps maintain a stable refractory layer, reduce molten-steel contamination risks and increase converter operating cycles.
