Advanced Melting Technology

Induction melting process, LRF ladle and CCM continuous casting

In Prima Steel Complex, the melt, after initial melting in EAF electric arc and induction furnaces, enters the Ladle Refining Furnace (LRF) for homogenization of chemical analysis and removal of sulfur and phosphorus, and then is converted into billet in 4-strand continuous casting machines with controlled cooling.

۱

Ladle Refining Furnace (LRF)

Precise adjustment of C, Si, Mn elements percentage and deep degassing to achieve premium mechanical properties.

۲

4-Strand Continuous Casting Machine (CCM)

Uniform solidification system free of any surface shrinkage and shrinkage cracks.
