    Abstract: A method of rolling NiW alloy tapes for coated conductors belongs to the technical field of metal materials rolling. According to the method, a cylindrical NiW alloy ingot with a diameter not less than 10 mm is used to be rolled back and forth along the axial direction as a rolling direction, wherein the content of W is 5˜7 at. %, and the axis of this ingot is perpendicular to the plane where the axes of working rollers are located. During rolling process, the cross sectional area reduction of the ingot is retained at 5% per pass. When the total cross sectional area reduction of the ingot is larger than 98% and the thickness of the tape is down to 60˜100 ?m, the rolling is stopped, and thus the NiW alloy tape is obtained.

    Abstract: A method of manufacturing large diameter tapered roller bearing cages includes beginning with a metal strip, coil or plate of cage blank material and feeding it into a rolling mill. The rolling mill includes a pair of unparallel forming rolls disposed to define a wedge-shaped gap therebetween. As the cage blank material is fed through the wedge-shaped gap, one lateral side of the cage blank material is plastically deformed to reduce its thickness and to elongate its length, while slight or no deformation is introduced into the other lateral side, thus forming the cage blank into an arc shape. A third roll disposed at the exit side of the forming rolls bends the rolled cage blank into a circular conical ring. Adjacent butt ends of the formed conical ring cage blank are aligned and joined together during the assembly process to form the large diameter tapered roller bearing cage.

  • Patent number: 8920938
    Abstract: With the invention a metallic flat product can be systematically made available with such a fine, stochastic or quasi-stochastic surface texture that after a typical automotive paint application it is only minimally perceptible, if at all, by the human eye. At the same time, in the case of a surface topography constituted according to the invention, the transition between the peak plateaus and the valleys takes place via steep flanks. In this way, it is achieved that the morphology of the sheet metal surface is practically independent of the actual depth of the valleys. As a result therefore, the morphology of the sheet metal surface of a metallic flat product according to the invention is also independent of the skin-pass rate, which is obtained when the fine metal texture is produced by skin-pass rolling.

The Ni—Ti alloy that includes nickel, titanium, and about 3 atomic % (at %) to about 30 at % niobium (Nb). Cold working the Ni—Ti alloy stabilizes the alloy's martensitic phase and yields a linear pseudo-elastic microstructure where reversion to the austenite phase is retarded or altogether blocked. The martensitic phase of cold worked, linear pseudo-elastic Ni—Ti—Nb alloy has an elastic modulus that is considerably higher than the comparable cold worked, linear pseudoelastic binary Ni—Ti alloy. This yields a guide wire device that has better torque response and steerability as compared to cold worked, linear pseudoelastic binary Ni—Ti alloy or superelastic binary Ni—Ti alloy.

The Si content may vary between approximately 4.7 and 10.9 wt %, and the Mg content may vary between approximately 0.15 wt % and 0.50 wt %. The alloy is well suited for operations in which little or no dilution from the base metal affects the Si and/or Mg content of the filler metal. The Si content promotes fluidity and avoids stress concentrations and cracking. The Mg content provides enhanced strength. Resulting joints may have a strength at least equal to that of the base metal with little or no dilution (e.g., draw of Mg). The joints may be both heat treated and artificially aged or naturally aged.

    Abstract: A stainless steel plate is manufactured by performing temper rolling using a dull roller after the finish cold rolling and bright annealing. The stainless steel plate has an arithmetic mean roughness Ra of 0.2 to 1.2 ?m in a direction perpendicular to the rolling direction of the steel plate surface. Furthermore, the stainless steel plate has a transfer ratio of 15 to 70% which is an area ratio of a portion onto which a dull pattern is transferred relative to the steel plate surface. In addition, the micro-pits being formed in the steel plate surface, having a depth of 0.5 ?m or more, and having an opening area of 10 ?m2 or more, have an existing density in the steel plate surface of 10.0 or less per 0.01 mm2, and an opening area ratio in the steel plate surface of 1.0% or less.

  • Publication number: 20130327110
    Abstract: There is provided a method for straightening a steel product, comprising using hard alloy straightening rolls each made of a tungsten carbide-cobalt (WC—Co) based sintered material (hard metal), wherein the hardness of each roll is HRA85 to 87. According to this straightening method, when bends of steel product are straightened, roll wear is suppressed, defective roll mark(s) caused by the roll wear is prevented from being formed on the surface of the product being straightened, and time for changeover and/or setup of rolls is shortened to enhance the operation rate of the straightening machine, whereby the efficiency of a finishing process and, in turn, the productivity can be improved. Therefore, this method is especially effective in the case where a product to be straightened is a high-strength product such as a steel pipe for a motor vehicle air bag.

  • Publication number: 20130273394
    Abstract: A method for surface treating work rolls to produce isotropic textured aluminum sheet features indenting the surface of the working rolls that produce the sheet with spherical media such as steel ball bearings having the requisite properties to avoid fracture and resulting in a smooth surface lacking facets. The spherical media can be introduced into a nip between two rolls and indent by compression, but ultrasonic peening or knurling. The aluminum sheet produced by the roll has properties that facilitate mechanical forming, such as when the sheet is processed by forming tools.
