Skamol materials in Torpedo Cars

| 300 tons torpedo car |
A typically torpedo car holds ca. 300 tons molten iron, and it is lined with ca. 120 tons of refractory bricks to keep the iron temperature high during transport. The tanks are shaped like 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 t 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
