High-Temperature Dry Casting

The Dry Casting technology is a cutting-edge solution designed to address some of the most pressing challenges in the steel industry. Low temperatures in continuous casting often lead to issues such as surface cracks, uneven cooling, and equipment wear, which can compromise product quality and operational efficiency. By enabling dry casting for high-temperature continuous casting, this innovative technology directly mitigates these issues, significantly improving the quality, reliability, and efficiency of the casting process.

Dry Casting transforms the continuous casting process by reducing or eliminating the need for spray cooling. This advanced technology ensures that heat is primarily transmitted through radiation and extracted by the strand guide rollers. By maintaining a high and uniform strand surface temperature, Dry Casting minimizes the risk of surface cracks and enhances the overall quality of slabs. The uniform temperature control prevents local overcooling, improving slab surface quality and reducing defects.

This technology is particularly effective for crack-sensitive steel grades, such as peritectic steel, micro-alloyed carbon steel, and advanced high-strength steels (AHSS). By maintaining a very high strand surface temperature, it prevents surface cracks in these sensitive steel grades. Additionally, Dry Casting extends the lifetime of casting equipment by reducing the heat load on rollers and segment frames, which lowers maintenance costs. The improved temperature control also increases yield and operational efficiency by reducing the need for slab scarfing efforts.

Benefits of Dry Casting Technology

• Elimination of surface cracks: significantly reduces transversal surface cracks, ensuring higher-quality slabs
• Enhanced slab quality: uniform temperature control leads to better surface quality and fewer defects.
• Extended equipment life: reduced heat load on components extends operational life and lowers maintenance costs.
• Higher yield: improved temperature control and reduced slab scarfing efforts increase overall yield.
• Cost efficiency: minimizes the need for expensive cooling systems and reduces maintenance efforts
