9th ECCC European Continuous Casting Conference – ECCC 2017

The dynamic soft reduction is more and more applied in bloom casting to improve internal soundness for long products, aiming to achieve consistent and reliable results in reducing V-shape segregation and central porosity. Soft Reduction for Round sections represents a new step ahead in CCM development, requiring a new concept for application to be effective, considering the “shape factor” of...

In the objective to improve the internal soundness of the as-cast round format 400mm in ArcelorMittal Ostrava, a strong collaboration has been launched between the team of the steel plant and the R&D centre of Gandrange, specialized in long products. In this framework, a focus has been made on forging grades, which have shown a high sensitivity to the occurrence of central cracks and...

This paper provides an overview about latest realized solution for the bloom continuous casters on the example of a heavy section bow type caster, which is equipped with latest technological packages. Bars and wires, which are rolled out of the blooms, serve as primary material for engine and gearbox parts for Hyundai Motors Group. The caster is equipped with latest mold-level control and...

In 2016 a new 5-strand bloom caster was installed and successfully commissioned by Inteco melting and casting technologies GmbH at Jiangsu Shagang, Shagang Group (CN). The CCM is designed to cast section size 300 x 390mm on a 9m vertical bending-unbending machine equipped with latest SBQ-Technology. Besides other features, a tundish design with optimised liquid steel flow distribution, large...

A new vertical caster for special steel grades was started up at Zhongyuan Special Steel Co., Ltd., in Jiyuan, China in June 2015. The 2-strand vertical round bloom continuous caster has a capacity of up to 370,000 metric tons per year, which enables Zhongyuan to produce additional high-quality steel grades, since the company only had an ingot casting plant for the production of mainly steel...
