MT 22 - TC 27/MT 22

Specifies the dimensions of turned and threaded cylindrical graphite arc furnace electrodes and graphite electrode pins for use as full graphite electrode columns on arc furnaces. Is essential for the interchangeability of electrodes from different sources.

Applies to cylindrical carbon electrodes, manufactured from upgraded coal, for use in electric direct-arc and submerged-arc furnaces, for melting silicium and carbide and for other purposes. Covers a) dimensions and tolerances on the length and diameter of carbon electrodes b) dimensions and thread details for carbon electrode heads and sockets.
