Arc furnace electrode slip monitoring device

摘要

An arc furnace electrode slip monitoring device comprising a frame-work adapted to be held fixed relative to a movable electrode, a movable unit supported by the frame-work and movable in reciprocating manner along a predetermined path which is substantially parallel to the direction of movement of an electrode. An electrode engaging member is provided in the movable unit movable transverse to the direction of movement of the movable unit to firmly engage an electrode during movement of the movable unit in one direction but to be disengaged therefrom during movement in the opposite direction. The slip monitoring device further includes detecting apparatus for detecting the position of the movable unit along its path of movement, and further apparatus for counting the number of reciprocal movements executed by the movable unit.
