Ladle Debricking Machine Function
Full-hydraulic telescopic boom equipment is used to break and remove aged & eroded refractory bricks (lining refractories) and solidified slag skull inside ladles. After stripping out worn linings, new refractory bricks are installed.
Standard fitted hydraulic breaker: breaks damaged lining bricks and crust slag on ladle wall and bottom.
Quick-change attachments available: reamer bits, digging shovels and raking claws for removing purging plugs and reaming ladle nozzle / tap hole.
Radio remote control operation keeps operators away from high-temperature ladles, replacing risky manual jackhammer work under harsh conditions of high heat, heavy dust and falling debris.
Removal of ladle bottom purging plugs (special model for LD converter service);
Trimming and reaming of ladle nozzle and seating brick holes to fit newly installed isostatic-pressed tap hole sleeves;
Auxiliary cleaning of skull and spent refractories for torpedo ladles, mixers and iron runners.
After dozens of heats, worn ladles are lifted to the refractory repair area by overhead crane for horizontal/vertical placement. The debricking machine enters the ladle opening to strip old lining layer by layer from inside out. The empty ladle is then relined with new refractories and pre-assembled with tap hole sleeves.
During ladle turnover intervals under residual temperature of 200~600℃, partial patching is carried out for local lining spalling, damaged purging plugs or broken tap hole sleeves. Only defective areas are demolished without full ladle relining to reduce production downtime.
Clean skull at converter mouth & cone; break out old bricks and ream tap holes for converters; remove tundish lining and spent refractories of blast furnace iron runners.
