Steel plants worldwide face a silent but costly problem: excessively high ladle shell temperatures. In many cases, temperatures exceed 300°C, posing serious risks to equipment integrity and wasting up to 18% of the heat energy used in continuous casting operations. Traditional insulation methods like thick ceramic fiber blankets or refractory bricks often fail under thermal cycling stress, leading to premature degradation and poor sealing.
Sunrise’s vermiculite-based steel ladle insulation board has emerged as a game-changer for furnace operators and maintenance teams. Unlike conventional materials, it offers:
| Insulation Type | Avg. Shell Temp (°C) | Heat Loss (%) | Life Expectancy |
|---|---|---|---|
| Traditional Fiber Blanket (50mm) | 320–350 | 15–18% | ~6 months |
| Sunrise Vermiculite Board (18mm) | 170–200 | 5–7% | ~18 months |
“After switching to Sunrise’s third-layer insulation, our ladle temperature dropped by an average of 50°C. The reduction in energy consumption translated to over 120 tons of standard coal saved per month.” — Li Wei, Senior Process Engineer, Baosteel Group
Proper installation is critical to performance. Key steps include:
If you notice localized hot spots (>250°C), check for missing bolts or damaged bonding — these can cause micro-leaks that accelerate heat loss and material failure.
As global steelmakers push toward carbon neutrality, efficient thermal management isn’t just operational best practice — it’s strategic necessity. By adopting advanced solutions like Sunrise’s third-layer insulation, plants not only reduce emissions but also extend equipment life and improve worker safety.
