Eccentric Bottom Tapping

Eccentric bottom tapping leads to slag-free tapping, shorter tap-to-tap times. It also reduces refractory and electrode consumption, and improves ladle life.

This technology is considered to have high application potential for China, India and the US - depending on the size, type and life of the existing unit if retrofit is considered.
