Abstract: A horizontal can necking machine assembly includes a plural of main turrets and a plural of transfer starwheels. Each main turret includes a main turret shaft, a main gear mounted on the main turret shaft, a pusher assembly, and a die capable of necking a can body upon actuation of the turret shaft. Each transfer starwheel includes a transfer shaft and a transfer gear mounted on the transfer shaft. The main gears are engaged with the transfer gears such that lines through the main gear center and the centers of opposing transfer gears form an included angle of less than 170 degrees, thereby increasing the angular range available for necking the can body. The main turrets and transfer starwheels may operate to neck and move at least 2800 cans per minute, and each pusher assembly may have a stroke length relative to the die that is at least 1.5 inches.

Abstract: The invention provides an arrangement for steelmaking comprising a steel melt and initial reaction chamber arranged to receive source material in the form of scrap and/or pre-reduced iron, an overhead lance for the introduction of an oxidizing gas to the initial reaction chamber, means for introducing, below the level of the surface of the melt in the reaction chamber, a melt stirring fluid medium, means for introducing carbonaceous material into the melt; a secondary refining chamber connecting with the initial reaction chamber at the surface level of the melt and through which the metal is arranged to pass from the initial reaction chamber; and a melt holding vessel into which the metal is passed from the secondary refining chamber.
