ABSTRACT:
A device for sealing the skirt of a converter waste gas recovery system is disclosed, which comprises a primary sealing apparatus adapted to enclose the converter mouth and mounted along the skirt along a lower edge thereof, a secondary sealing apparatus adapted to encircle about the primary sealing apparatus, and primary hydraulic cylinder for vertically moving the skirt together with the primary sealing apparatus, and a secondary hydraulic cylinder for vertically moving the secondary sealing apparatus independently of the primary sealing apparatus. The primary sealing apparatus is intended to provide sealing for the gap between the skirt and the converter mouth. The secondary sealing apparatus serves to insure sealing when the primary sealing apparatus has failed to provide proper sealing because of adhered slag along the rim of the mouth from prolonged operations. Either or both of the sealing apparatuses include a sealing jacket adapted to enclose the skirt and filled with water and a sealing plate built to extend along the sealing apparatus and mounted to have its lower portion submerged into the water in the sealing jacket for sealing and cooling the respective sealing apparatus in the heat generated by the converter.
