Abstract
A safety device for protecting a cover used for closing a vessel in which molten metal undergoes metallurgical treatments is presented. The device is used in conjunction with the type of cover which rests on or hangs over the edge of the vessel. The device comprises a plurality of segments which preferably form a substantially cylindrical or funnel-shaped space. These segments may have any variety of configurations and/or shapes so long as they effectively eliminate the splashing and frothing of molten metal and slag.
