Insulation Sheet / Dorupak 90
Insulation Material
High-temperature insulation that cuts ladle body temperature by ~60°C.
High-temperature ladle insulation reduces heat loss through the vessel shell. DFP India's High Temperature Insulation Sheet and Dorupak 90 sit behind the working lining and cut the ladle's outer body temperature by roughly 60°C versus an uninsulated equivalent. That lowers radiant heat loss and the energy needed to hold pour temperature, and reduces thermal stress on the working lining behind it — extending refractory life.

Case in point
Cutting ladle heat loss and extending working-lining life
A ladle fitted with DFP's High Temperature Insulation Sheet and Dorupak 90 runs roughly 60°C cooler on its outer shell than an uninsulated equivalent — lower radiant heat loss, less energy draw to hold pour temperature, and less thermal stress on the working lining behind it.
Competitive edge vs. generic / local
- Roughly 60°C lower outer-shell temperature cuts radiant heat loss and the energy needed to hold pour temperature.
- Less heat loss through the shell reduces thermal-cycling stress on the working lining, extending refractory life.
- A complete backup-insulation system (sheet + Dorupak 90 + repair compound) rather than a single bought-in board.
What changes when you switch
| Aspect | Uninsulated ladle | With DFP insulation sheet / Dorupak 90 |
|---|---|---|
| Shell temperature | Baseline | ~60°C lower |
| Energy/power consumption | Higher, to offset heat loss | Reduced |
| Refractory life | Shorter, more thermal cycling stress | Extended, less heat-loss-driven stress |
Frequently asked questions
How much heat does ladle insulation save?
Roughly 60°C reduction on the ladle's outer body temperature.
Does insulation extend refractory life?
Yes; less heat loss reduces thermal stress on the working lining.
What products make up DFP's insulation range?
High Temperature Insulation Sheet, DoriDur RC 1651, and Dorupak 90.
How does ladle insulation save energy?
By cutting outer-shell temperature ~60°C, it lowers radiant heat loss and the energy needed to hold pour temperature.
Where does insulation sheet sit in the ladle?
Behind the working lining, as a backup insulation layer, reducing thermal-cycling stress on the refractory in front of it.
