DEVICE FOR FASTENING A PERFORATED BLOCK, AND PERFORATED BLOCK

摘要

In a device for fastening a perforated block (1) to a metal melt container, the perforated block (1) can be fastened by means of at least one clamping wedge (36) which can be inserted transversely with respect to its through opening (D) and which has a clamping jaw (35) coupled thereto, wherein this clamping jaw (35) acts on a clamping surface (13) formed on the circumferential surface of the perforated block (1). The respective clamping wedge (36) is guided in a carrier plate (33) so as to be displaceable in its longitudinal extent and transversely with respect thereto, while the clamping jaw (35) coupled thereto can be moved in this transverse direction. Consequently, the perforated block can be fastened with precise positioning in the carrier plate (33) in a simple manner.
