Abstract
The invention provides a DC furnace bottom electrode connector, an electrode, electrode hearth and a DC furnace. The electrode connector includes a circular flat metal plate which is dimensioned to be similar to the circumference of it corresponding furnace. The plate distributes current flow more evenly and non conductive areas provided in the plate can be used to manipulate current flow to minimise arc deflection.
