The Ladle Preheating Device is a critical auxiliary unit within the steelmaking and continuous casting production line. Though often overlooked, it plays a decisive role in stabilizing the tapping temperature of the steelmaking furnace, improving furnace turnaround time, and maintaining casting quality. By ensuring that the ladle reaches optimal thermal conditions prior to molten steel reception, the system helps preserve energy, extend ladle lining life, and reduce thermal shock. LIWEI's ladle preheaters are engineered with oil-gas dual-purpose burners and advanced heat recovery systems, supporting a wide range of fuel types and enhancing energy efficiency throughout the casting workflow.
Positioned between steel tapping and continuous casting, the ladle preheater is vital for maintaining a stable temperature profile across the production flow. Proper preheating improves molten steel transfer, reduces temperature fluctuation, and ensures smoother downstream operation of the continuous caster.
LIWEI has developed an oil-gas dual-purpose burner compatible with multiple energy sources, including natural gas, converter gas, blast furnace gas, light diesel, and heavy oil. This flexibility allows steel plants to optimize fuel selection based on cost, availability, and environmental regulations.
To reduce operational energy costs, the system can be equipped with preheating units where air or gas is reheated using flue gases. Options include separate burner + heat exchanger systems or self-preheating burners. These configurations elevate combustion temperature, decrease fuel consumption, and maintain high-velocity flame energy for uniform and efficient ladle heating.

By preheating the ladle before pouring, the device minimizes molten steel temperature loss and reduces the time required to reach pouring readiness. This ensures higher production efficiency and fewer casting interruptions.
LIWEI’s regenerative ladle preheaters utilize waste heat to prewarm combustion air or gas, leading to elevated flame temperatures without additional fuel usage. This approach significantly lowers operational costs while meeting energy-saving goals.
Our ladle roasters are built using high-grade refractory linings and wear-resistant alloys, ensuring long service life even under high thermal stress. Modular design supports integration into both existing and newly designed casting lines.
Ideal for steel plants aiming to boost casting stability, ladle preheaters are essential in balancing furnace tapping and caster requirements. They help maintain the correct molten steel temperature during transfer, particularly in long-distance or delayed pouring situations.
Plants implementing energy recovery and fuel-flexible strategies benefit significantly from LIWEI’s preheating systems. Our solutions are compatible with clean fuel upgrades and automation systems, making them future-proof and efficient.
