METALLIC FRAME FOR A POURING NOZZLE, ASSEMBLY OF A METALLIC FRAME WITH A POURING NOZZLE AND DEVICE FOR THE INSERTION AND/OR REMOVAL OF A POURING NOZZLE

摘要

The present invention relates to a metallic frame used to girdle a pouring nozzle used in a device for the insertion and/or removal of a pouring nozzle of a molten metal casting installation. The invention also concerns an assembly of such a metallic frame with a pouring nozzle. According to another of its aspects, the invention concerns a device for the insertion and/or removal of a pouring nozzle of a molten metal casting installation which is particularly adapted for using the metallic frame of the invention. The metallic frame is provided with coupling means to pulling means of the device for the insertion and/or removal of the nozzle and with coupling means (11) to a manipulator. Thus, the time required to insert a new nozzle is reduced so as to reduce or even eliminate the risk of the molten metal freezing in the casting channel, particularly in case of non natural opening of a ladle.
