CRUCIBLE FURNACES WITH NODULATED WALL FOR INDUCTION MELTING

摘要

An induction melting crucible is prepared from electricity insulating material, optionally provided with a rim and/or pouring spout of the same product. The crucible is dimpled partly or throughout on its internal wall (BP) and base (BF) as indicated by the spread out planar design. Alternatively, the external surface of the crucibles prepared from an electricity conducting material are dimpled as shown by a planar design. The internal surfaces of a particular electricity insulating material-based crucible are dimpled over the whole surface area. The dimensions of the evenly spaced dimples are identical.
