Nippon Steel High Speed Variable Width Mold 'NS-VWM' for Slab Caster

摘要

In slab continuous caster, when slabs with different widths are to be produced, casting has to be stopped in order to change the mold width to the required size. The technique to solve such problem is variable width mold which can change the mold width during casting. Nippon steel developed the high speed variable width mold "NS-VWM" which permits us to shift mold width changing speed to higher speed by a combination of change of narrow face taper and parallel movement. In this paper, the features and effects of this equipment are outlined.
