Skamol materials in Torpedo Cars

300 tons torpedo car

The load in torpedo cars is normally 200-400 tons of molten iron.

A 300 MT torpedo car is lined by ca. 120 tons of refractory bricks or blocks to keep the iron temperature high during transport. The tanks are shaped as a torpedo to resist the enormous pressures from splashing liquid iron during transportation.
The volatility and erosive nature of molten metal make monitoring the torpedo car's refractory lining a vital maintenance function. The consequences of a breakout are considerable, in terms of safety and cost.

SKAMOL VIP-12 HS in Torpedo Cars

Implementing 17 mm SKAMOL VIP-12 HS as back-up in the 330 MT torpedo cars will bring the iron temperature up by 25-30ºC depending on transport time.

To improve and decrease the heat flow for open torpedo cars, it is proposed to implement a lid consisting of Al-SiC-C, HiAl and backed up by 17 mm SKAMOL Super-1100E. This will give an additional temperature rise of 40-60ºC.

Benefits by implementing SKAMOL VIP-12 HS in torpedo car linings:

1. Slimmer refractory lining
2. Reduced heat flow
3. Lower shell temperature
4. Safer transportation
5. Higher temperature of iron delivered at the BOF
