Abstract:
The invention relates to a deep rolling roller head (1) of a deep rolling tool for deep rolling radii or recesses (22) on the main and lifting bearing journals of crankshafts (21). Said deep rolling roller head is equipped with a housing (2) inside of which one or two laterally interspaced deep rolling rollers (4) are rotationally guided in a loose manner and with little play in two roller cages (5, 6). The roller cages (5, 6) are fastened to supports (15) on the face (3) of the housing (2) oriented toward the crankshaft (21). Said supports support the roller cages (5, 6) on their faces (10) oriented away from the deep rolling rollers (4) while laterally guiding them at the same time. The face (3) of the housing (2) oriented toward the crankshaft (21) is provided, on both ends thereof, with a projection (11, 12) for supporting each of the roller cages (5, 6). A fastening and guiding element (15) is provided for each roller cage (5, 6), engages inside the roller cage (5, 6), and can be fastened to one of the projections (11, 12) of the housing (2) at the same time.
Abstract:
The invention relates to a deep-rolling roller head (1) of a deep rolling tool with deep-rolling rollers (2) that are rotatably mounted in roller cages (3) and are at a distance (4) from the center (5) of the underside (6) of the housing (7) of the deep-rolling roller head (1) and are supported on the front (8) at the end of the long leg (9) of two L-shaped holding devices (11) that can be adjusted and fixed in the direction of the center (5). A first screw (13) enters an oblong hole (12) in each long leg (9) to hold the L-shaped holding device (11) on the underside of the housing (7) while a second screw (14) passes through a bore (15) in each short leg (10 and enters a bore (26) in the adjoining front (21) of the housing (7), being provided in order to adjust the precise position of the roller cage (3) relative to the center (5). With the L-shaped holding device (11) shown on the left half of the drawing the front (25) adjoining the underside (6) is at a predetermined first distance (18) from the center (5) over a segment (17) of its length. The appertaining short leg (10) is supported over a segment of its inside on the segment (17) of the housing (7). The front (8) of the appertaining long leg (9) is at a predetermined distance (17) from the segment (17).
Abstract:
The invention relates to a deep-rolling roller head (1) of a deep-rolling tool for the deep rolling of radii or undercuts (22) on the main and stroke journals of crankshafts (21), with a housing (2) in which one or two deep-rolling rollers are tracked with little clearance and are loosely rotatable in a roller cage (5) at a lateral distance from each other. The roller cage (5) is attached to underside (3) of the housing (2) towards the crankshaft (21) by means of pins (15) which support the roller cage (5) on its face (10) away from the deep-rolling rollers (4) and at the same time track them laterally. The housing (2) is provided with a projection (11, 12) for the support of the roller cage (5) on either end of its underside (3) towards the crankshaft (21). Pins (15) serving as fastening and tracking elements of the roller cage (5) are provided and engage the roller cage (5).

Abstract:
A process for the production of steel with increased ductility in which a sulfur-containing steel melt is deoxidized and, if desired, is supplied with alloying elements, the deoxidized melt is treated with calcium as part of a purification action simultaneously reducing the sulfur content and the reaction is carried out in a casting ladle having a lining free from siliceous oxides. The melt is covered with a synthetic slag free from siliceous oxides and the calcium-containing substance is introduced in fine-grain particulate form into the melt in a carrier gas at a level at least 2000 mm below the melt surface and at a rate which is less than the maximum rate at which the calcium-containing substance is capable of reacting with the melt.
Abstract:
A steel melt is confined and subjected to a partial vacuum. A particulate additive is entrained by a neutral nonreactive carrier gas and introduced into the melt below the surface thereof at a depth such that the additive is immediately vaporized and rises toward the surface of the melt in the form of bubbles which react with components of the melt. With particulate calcium as the additive an injection depth 1500 mm, a temperature of approximately 1500.degree.C, and a vacuum of 20 Torr allows the sulfur content of a steel melt readily to be reduced below 0.005% by weight.
