The electrode column:
The electrode column delivers the electrical power to the furnace burden. It must accept the power from the high-current transmission system via flexibles designed to facilitate the full regulation stroke of the column and deliver the power to the furnace via either a pre-baked or process-baked conductive electrode.
The electrode column is suspended from- or is standing on regulation cylinders attached to the furnace building structure. It is firmly guided down through the roof and delivers the conductive electrode stump to the furnace burden.
Making use of a patented copper alloy, the hot forged segmented pressure ring assembly is able to withstand the onerous under-roof conditions whilst resisting creep and deformation. The individual segments are bound by our patented C-clamp that reliably brings the segments together and binds them whilst the bellow exerts the necessary pressure on the contact shoes to ensure optimal current transmission to the electrode. The lower electrode is suspended on the electrode mantle. On the mantle the layout of the current conductors and cooling water risers maximises insulation integrity and ensures a “clean”, clutter-free arrangement for intuitive problem solving. Segmented heat shields made from either forged copper or stainless steel protect the mantle components beneath the furnace roof.
