Abstract:
In a sliding chain-type ingot mold (12, 13), each mold is constituted by molding elements (14, 15; 114, 115; 214, 215) representing two half-molds which can be made to face each other so as to form a closed mold shaping a cavity to hold the molten metal. According to the invention, some engaging elements (34, 134, 234) are provided, capable of interacting with cam-shaped surfaces (33, 133, 233) provided on one side on at least one (14, 114, 214) of said molding elements, and on the other side on a fixed frame (35) designed to detach and approach said molding elements.
Abstract:
A multifunction injector (10, 11, 12) comprising a De Laval nozzle (20) adapted to act as a burner at subsonic or supersonic speed, combined with a plurality of nozzles (31, 32) for fuel and comburant respectively, arranged in two rings, concentric and co- axial to said De Laval nozzle (20) and externally protected by a specifically shaped protection cavity (40).
Abstract:
A roller cleaning system (10) for an oven (20) equipped with a series of motorized rollers (21) each of which is in turn connected to a relative motor-reducer (24) for rotation activation, in turn connected to a relative frequency converter (25) driven by a respective control and activation device (26), said roller cleaning system (10) comprising a control and regulation unit (14) to independently control the rotation rate and direction of each roller of the series of motorized rollers (21) for the advancing of one or more flat blooms (40) and for cleaning at least one roller (34) causing the detachment of the flakes of oxide therefrom by scraping it against a flat bloom (40) with a variation in the rotation rate and/or direction of the same.
