A roll for transporting elongated ferro-magnetic bar-like products, includes a series of axially aligned magnetizing coils, and a magnetic circuit around each coil. Each magnetic circuit comprises an annular magnetic core within the coil, magnetic elements extending from the core on each side of the coil, and ring means surrounding the coil. The ring means includes a nonmagnetic portion of less width than that of the magnetic portion. The coils are supplied with direct current, and the roll is mounted on a non-magnetic shaft.
摘要:
Process for producing a motorized land vehicle wheel, in general having a wheel disk and an essentially cylindrical rim, the wheel disk being obtained from a blank plate of specific thickness subjected to several shaping operations, and composed of an essentially flat central part having an opening that serves to center and attach the wheel to the vehicle's axle hub, an essentially conical interior riser, another inverted conical part that defines, with the interior riser, a curved tip that has a large radius of curvature, the inverted conical part terminating in a flanged edge used to join the disk to the rim, a process characterized in that during the forming operation of the flanged edge, the plate is laminated in such a way as to preserve or reduce the thickness of the base plate.

The machine for cooling metal sheets or plates comprises a casing having at least two parallel planar portions in facing relation to each other and defining therebetween a gap whose width exceeds the thickness of the sheet to be cooled so as to define two chambers with the sheet. A series of sheet guide and support rollers extend transversely of the longitudinal direction of the sheet. The casing comprises part-cylindrical portions surrounding the rollers and the planar portions are disposed between two adjacent ones of the rollers which are located on the same side of the sheet. Cooling water is supplied to the chambers and flows in a direction substantially parallel to the plane of the sheet.
摘要:
Process for quenching steel and rails, in a fluidized powder medium. The fluidized medium is formed by mixing a powder of chromium, iron, nickel, molybdenum or tungsten, or alloys of these metals, with a pure steam or a gas comprising essentially steam.
摘要:
Roll for transporting rolled steel products comprises rings of ferromagnetic material separated by rings of nonmagnetic material. All rings have same diameter but nonmagnetic rings are narrower than magnetic rings. Annular coil within each magnetic ring supplied with DC power to magnetize ferromagnetic rings. Entire assembly mounted on rotatable shaft. Apparatus may comprise plurality of such rolls on parallel shafts with idler rolls between them; nonmagnetic rings of the rolls being out of alignment.
