The Tundish Preheating Device from LIWEI is designed to enhance casting stability and steel cleanliness by bringing the tundish to optimal temperature before pouring. This process minimizes thermal shock, prolongs the lining's service life, and ensures a consistent flow of molten steel. The device features rapid heating performance, advanced combustion control, and seamless integration with modern casting lines. Applicable in both small foundries and high-capacity continuous casting facilities, it offers a flexible and efficient solution that aligns with the demands of modern steelmaking.
Equipped with a PLC-based control system and intuitive HMI interface, the preheater enables precise temperature regulation and real-time monitoring. This automation reduces manual errors and enhances operational stability across different production conditions.
The system utilizes low-emission burners or electric heating elements to ensure uniform and efficient heat distribution. Optimized for minimal fuel usage, it helps reduce energy costs while supporting environmental compliance.
Designed for fast thermal response, the device heats the tundish quickly and evenly. This prevents cold spots and temperature drops, which are common causes of casting defects such as cracks, inclusions, or inconsistent grain structure.
| Parameter | Value |
|---|---|
| Application | Tundish Preheating in Continuous Casting Lines |
| Heating Method | Gas-Fired or Electric (Optional Hybrid Systems) |
| Control System | PLC + HMI Interface with Alarm & Auto Functions |
| Fuel Efficiency | High Efficiency, Low Emissions |
| Preheat Time | Rapid Ramp-Up (< 30 minutes depending on design) |
| Safety Features | Flame Detection, Overheat Protection, Auto Shutdown |

| Applicable Steel Types | Carbon, Alloy, Stainless Steel |
Constructed with heat-resistant materials and industrial-grade components, the system ensures durability and minimal maintenance even under high-temperature, dust-heavy conditions typical of steel plants.
LIWEI’s tundish preheater can be configured to fit a wide range of plant layouts and production scales. Whether upgrading existing lines or building new capacity, the modular structure allows easy customization and installation.
With installations in over 50 countries and more than 300 successful cases, LIWEI has a proven record in delivering energy-efficient tundish preheating solutions that consistently improve casting performance across a variety of steel grades.
Our tundish preheater is widely used in billet, bloom, and slab casters, helping stabilize molten steel flow and enhance surface and internal quality.
It is especially valuable in high-grade steel production, where strict thermal control is critical to achieving target microstructure and mechanical performance.
With over 26 years of metallurgical expertise, LIWEI offers complete, customizable steel plant equipment solutions. Our tundish preheating devices are designed by experts with global project experience and supported by full-cycle service—from engineering design to on-site commissioning. We are the trusted partner for more than 300 clients in Asia, Europe, the Middle East, and beyond.
A: By maintaining consistent tundish temperature, it reduces thermal shock, enhances flow uniformity, and minimizes internal defects.
A: Yes, we offer gas-fired, electric, or hybrid versions depending on your energy supply and environmental goals.
A: Absolutely. Our modular design supports compact configurations, making it ideal for retrofits or space-sensitive layouts.
