Abstract
A dummy bar head for a continuous casting installation, particularly for casting steel, containing a dovetail-shaped coupling portion which can be decoupled by carrying out a relative movement between the dummy bar head and the cast strand. The relative movement is undertaken in a direction approximately transverse to the strand withdrawal direction. To ensure a disturbance-free starting of the continuous casting operation, with high casting speeds, the dovetail-shaped coupling portion comprises a raised or protruding dovetail-shaped body. The dovetail-shaped body or body member essentially contains a trapezoidal-shaped surface area. A boundary surface of the raised body has aligned therewith a boundary surface of the dummy bar head which is arranged in the strand withdrawal direction and as to the remaining three boundary surfaces at least two oppositely situated ones thereof contain undercut portions.
