Zusammenfassung:	Provided is a pressure ring assembly for contact shoes in an electrode system of an electric arc furnace provided with at least one electrode column assembly. The electrode column assembly comprises a contact shoe ring formed of a plurality of contact shoe elements, a pressure ring formed of a plurality of pressure blocks, and a heat shield formed of a plurality of heat shield segments. An elongated groove is formed on both substantially vertical side edges of each pressure block, and an elongated lock bar is placed in the grooves of two adjacent pressure blocks to join said pressure blocks with each other. The form of the lock bar essentially matches to the form of the grooves of said two adjacent pressure blocks. Each lock bar is locked in place in the grooves by fastening bolts through holes in the pressure blocks.
