1. Main Functions

1. Remove waste refractory bricks

   Remove the working layer refractory bricks on the inner wall of torpedo cars that peel off due to erosion by high-temperature molten iron, slag and thermal shock, while retaining the safety lining to prevent damage to the tank body.

2. Clean slag and crusts

   Crush and remove hard steel slag, iron nodules and cold hard layers on the tank mouth, tank bottom and curved walls to restore the effective volume.

3. Clear tank mouth and tapping hole

   Remove blockages and adhered slag at the two end cone mouths, central manhole and tapping hole of torpedo cars to ensure smooth molten iron transportation.

4. Remote operation & high temperature resistance

   Equipped with remote control for operation in safe areas. It can withstand temperature up to 1600°C and work before the tank cools down completely, greatly cutting downtime.

5. Precise operation without damaging safety lining

   Combined with hydraulic hammer and telescopic boom for precise control. It only removes working bricks without harming the permanent safety lining, extending the service life of the tank body.

2. Typical Application Scenarios

1. Routine maintenance of torpedo cars in steel plants

   Periodic brick removal and overhaul for 200–600 ton torpedo cars serving between blast furnaces and steelmaking workshops.

   Maintenance cycle: Once every 3 to 6 months. Manual work takes 3 to 5 days per tank, while the machine only needs 8 to 12 hours per tank.

2. Operation in narrow and high-temperature areas of metallurgical workshops

   Torpedo cars feature small openings, long interiors and curved walls, which are only accessible for the debricking machine with telescopic boom and remote control. The working environment is featured with high temperature, heavy dust and harmful gas, posing great risks to manual workers.

3. Pre-treatment before refractory replacement

   Thoroughly clean waste bricks and residual slag before laying new refractory bricks, so as to ensure tight adhesion and longer service life of new bricks.

4. Extended application (same series equipment)

   Removal of refractory bricks and slag cleaning for ladles, converters, electric arc furnaces (EAF) and blast furnace runners.
