Improvement in the production of high grade wire rods and bars by using a billet caster

Kobe works is equipped with two casters : a bloom caster and a billet caster. For improving the product quality at the billet caster, some techniques are developed : inclusions decreasing, surface defects decreasing, center segregation reduction. A precise control of the temperature in tundish has been carried out. As a result, a new target is to produce higher grade steels.
