Torpedo ladle cars are used for long‑distance transportation of high‑temperature molten iron. Their inner walls are lined with thick refractory bricks. Subject to long‑term scouring by molten iron and corrosion by slag, the linings suffer damage, metal nodules and slag build‑up, which requires periodic removal of old refractory materials for re‑bricking. The torpedo ladle lining de‑bricking machine is a special hydraulic equipment dedicated to removing spent refractory materials.
Removal of damaged refractory lining Hydraulic breaker hammers are applied to crush eroded and cracked working‑layer refractory bricks inside the ladle. Impact force is controllable to protect the backup permanent lining and steel shell structure and prevent damage to the ladle body.
Removal of metal nodules, slag deposits and skulls Clear metal nodules and solidified slag skulls adhering to the ladle wall, bottom and two end cones, so as to restore the effective capacity of the torpedo ladle.
Clearing critical sections Remove blocked slag and bricks at end cones, tap‑holes and manholes to keep the molten iron passages unobstructed.
Pre‑treatment for maintenance Remove old bricks and clear debris and residues to prepare the ladle for new refractory brick installation.
Replacement of manual jackhammer work Remote‑controlled operation keeps operators out of the high‑temperature ladle, avoiding hazards such as falling bricks, high temperature and dust. Hot‑ladle operation is supported without full cooling of the tank, greatly shortening maintenance downtime and improving ladle turnover efficiency.
