Joining up dummy bar in continuous steel casting - by leaving gap between mould wall and sleeve, lining plate with paper or plastic foil etc.

摘要

In a continuous steel casting procedure, the joint to a dummy bar is effected in the ingot mould by leaving a first gap between the mould wall and a sleeve, filled with steel scrap, at the head of the dummy bar. A thick plate at its bottom end is lined with paper or plastic foil and is sealed by graphite seals the periphery of a smaller second gap. This assembly is joined to the dummy bar by a rectangular coupling bar, bolted to the dummy bar head. ADVANTAGE - This method has a higher rate of success. The parts used cost little and some can be re-used.
