Publication number: 20180056348Abstract: This invention provides a method for producing a polishing bar made of valve steel 53Cr21Mn9Ni4N. The process flow is as below: electric furnace smelting?outside-the-furnace refining?continuous casting?heating?high-speed wire rolling?heat treatment (off-line/online)?straightening?polishing?inspection?storage. The production method of the invention adopts a casting method of continuous casting to overcome the poor high-temperature plasticity and the great deformation resistance of 53Cr21Mn9Ni4N which leads to a difficulty in continuous casting. The continuous casting is directly carried out on casting billets for rolling, which greatly reduces the material loss and energy consumption of this step, and improves the yield of the billets. The high-speed wire precision rolling technology is directly used on the continuous casting billets to improve the production efficiency, and greatly improve the size precision control of rolled and finished wire rods.Type: ApplicationFiled: August 22, 2017Publication date: March 1, 2018Applicant: Jiangsu SHENYUAN Special Steel Co.,Ltd.Inventors: Guofu ZHANG, Yuguo TU, Dejian ZHAI, Hongsheng KE, Guoping SHEN, Weibin XUE

Publication number: 20180056349Abstract: A method for producing metal strip in a rolling mill, so that as a result of a more accurate manufacturing of metal strips in the future, a more precise forecasting of the profile contour of the metal strip can be obtained over the width of the metal strip, as well as a more precise setting of the profile actuator of the rolling mill. A forecast value is calculated for the profile contour within the context of the simulation of the rolling process before the rolling of the metal strip. In contrast to that, the calculation in the simulation is not conducted prior to the rolling, but instead it is obtained by a post-calculation after the rolling of the metal strip has been carried out.Type: ApplicationFiled: March 15, 2016Publication date: March 1, 2018Applicant: SMS group GmbHInventors: Jürgen Seidel, Uwe Baumgärtel, Ralf Wachsmann

Publication number: 20180056350Abstract: An improved system and method of producing nanostructured or ultrafine grained metals is disclosed. In one embodiment, an improved system and method of producing nanostructured materials includes extruding the material through two deformation zones. The first zone consists of an inlet channel for inputting the material and a narrow channel through which the material is extruded, thus reducing its diameter. The second zone is an angular channel through which the compressed reduced diameter material is extruded to increase its diameter back to the original diameter. This eliminates the need for a dual press to provide back pressure to the material for increasing its diameter. Moreover, the total amount of strain applied to the material includes strain applied as a result of extrusion through the narrow channel and strain applied as a result of extrusion through the angular channel. As a result of the additional strain, fewer passes through the system are needed to achieve a desire strength.Type: ApplicationFiled: November 6, 2017Publication date: March 1, 2018Inventors: Mahnaz Ensafi, Ghader Faraji

For example, a removable or portable apparatus can be applied to the surface of the supply bin once the bin has been filled. The apparatus can include a vibrational component that agitates the underlying powder to compact the material. The apparatus can then be removed during the remainder of the additive manufacturing process, which then follows in its normal course. A vacuum can also be used the remove of air or other gases that are emitted during the compaction process, for example, as voids are filled during densification.Type: ApplicationFiled: August 22, 2017Publication date: March 1, 2018Applicant: EOS GmbH Electro Optical SystemsInventors: Ankit Saharan, III, Erling Richard LaSalle

Publication number: 20180056388Abstract: A method of manufacturing a structural component having tailored material properties by applying an IR-absorbent coating to a substrate formed of a ferrous-based, aluminum-based, magnesium-based, or fiber reinforced composite material is provided. The coating is preferably formed of iron oxide (Fe304) decorated multiwall carbon nanotubes. Alternatively, the coating is wax-based or polymer-based and includes TriSilanollsooctylt POSS and additives. Different coating compositions may be applied to different zones of the substrate so that the emissivity coefficient varies along the substrate. The coated substrate is heated and formed between a pair of dies to achieve a complex shape or features. The IR-absorbent coating increases the infrared absorption rate during the heating step, which improves formability of the substrate.Type: ApplicationFiled: March 2, 2016Publication date: March 1, 2018Inventors: Timothy Walter SKSZEK, Xiaoping NIU, Thomas James OETJENS
