摘要

Casting equipment and method of extraction and removal of a spear to inject solids of a metallurgical vessel. A metallurgical vessel (11) is a tubular spaced perimetricamente bezels (25) by means of which extend spears to inject solids (31) within the vessel.The equipment for the extraction of spear (33) comprises an elongated track support structure (41), and a track rails (40), double inclined upward and in the external direction of the vessel, above the direction of inclination of a respective posts (31).The upper and inner wagons connected (42, 44) can be moved along the track (40) by operation of a winch (47). The equipment of extraction (33) is operable to sequentially to remove sections of the line of the release of solids (36) and (37) and spear (31) by connecting the wagons (42, 44) and the upward movement of the carriages along the track (40).The wagon top (42) has a pivot arm (51) for connecting the upper parts of the components to be removed, so that these components can be articulated descendentemente to positions in which they can be hung from a crane suspended for REM Emotion in a distant place.
