Melting and casting plant for vacuum or protective gas operation with at least two chambers

摘要

The invention relates to a melting and casting plant with two chambers (1,2), a valve (3) being arranged in their horizontal partition (20). A melting device (6) is arranged in the upper chamber (1), and a crucible lifting device (17) with a linear vertical guide (21) is arranged in the lower chamber (2). To achieve the object of excluding lack of sealing at places where drive portions for the crucible pass through, it is proposed according to the invention that within the lower chamber (2) a rotary drive (29) and a device for converting the rotary motion into a vertical motion of the crucible (11) are associated with the vertical guide (21). <IMAGE>
