Biggest continuously cast round steel bloom
The new three-strand caster for big blooms of up to 1,000 mm diameter by SMS Concast sets a mile stone in steel production history.
Together with SMS Concast, Taewoong has successfully designed, commissioned and is now running a caster, with a casting radius of 18 m. This ensures the elongation within the straightening zone remains below permissible values, even in the case of grades which are susceptible to cracking. The result is that 100% of the blooms can be produced without cracks. Moreover Taewoong could reduce their re-stranding times of up to 65% by using the top feeding dummy bar system by SMS group.
