ABSTRACT:
A sound and dust insulating wall separates the furnace hall from the casting hall in a metallurgical mill. In order to allow the transport of an overhead crane from one hall to the other, an upper wall portion of the separating wall pivots out of the way. The wall portion comprises frame elements and a plurality of relatively thin overlapping slats. The wall portion is opened by pivoting the frame elements about a horizontally extending hinge. The slats, secured to the frame elements by hinges, also pivot, so that the slats only block the now opened crane passageway by not more than the width of one individual slat.
