March 17 reported that people familiar with the matter said that Samsung Electronics will deploy facial recognition technology for mobile payments within a few months after the release of the new Galaxy S8, adding cutting-edge security technology to help this big screen device from rivals such as Apple's iPhone Products stand out. According to people close to the situation, the Galaxy S8 will be released later this month to provide users with access to mobile services such as Samsung Pay fingerprint, iris and facial detection certification. Samsung has also been working with banks to help them embrace facial recognition systems in the coming months. Samsung Galaxy Nexus needs to launch a hot cellphone after the Galaxy Note7, which is vulnerable to fire, is being stopped. Samsung Galaxy Note7 lost more than 60 billion US dollars, losing the world leader in intelligent machines. The success of the Galaxy S8 is crucial to salvage Samsung's reputation, especially when the actual head of the company, Jay Y. Lee, was arrested for corruption in South Korea. The Galaxy S8 also needs to contend with Apple's new-generation iPhone later this year, the latter celebrating its 10th anniversary this year. Although previous Galaxy handsets have allowed users to unlock their handsets using facial recognition technology, the Galaxy S8 will be the first to use the technology to certify financial payment applications. Informed sources said that as consumers pay more and more attention to mobile security, Samsung has been trying to improve the accuracy of facial recognition over the years. Iris and face detection complement each other: When the ambient light is too dark to recognize facial features, the phone can rely on iris scans. However, relying on face detection technology, intelligent machine unlock faster, more accurate. Competitors are also developing facial recognition technology. In the past few years, Apple has acquired several developers of facial recognition technology and won a patent last week that uses the information in digital video streams to detect faces. Samsung also hopes to make its Galaxy S8 stand out from its up-and-coming show with other features that its rivals include Chinese makers such as Huawei and OPPO. Informed sources said, Galaxy S8 will also have built-in voice digital assistant. However, the digital assistant is largely self-developed by Samsung, and the first version did not draw on the technology of much of Viv Labs' artificial intelligence software company. Samsung acquired the U.S. company Viv in October last year. The front of the Galaxy S8 will be full screen design, cancel the Home physical key. This borderless design will provide more room for visualization, but Samsung hides a virtual Home key at the bottom. It will also be equipped with a more energy efficient OLED screen.
Cold drawn steel bar is produced by Hot Rolled Steel Bar or wire rod to get smooth surface, more precision size, higher mechanical properties, which improves machining characteristics. It can also get various sections and sizes. So cold drawn steel bar is a better choice for machining users.
For high carbon steel or alloy steel bars, to avoid the cracks in inner or surface, the bars are usually required to be annealed before cold drawing.
To get different mechanical properties or hardness depending on final usage, the cold drawn bars will also be heat treated such as annealed, normalized or quenched and tempered(Q&T).
For CNC machines usage, to get much more precision sizes or much more better surface roughness for chrome plating, the cold drawn steel bars can also be centerless ground or polished.
We have more advantages on producing cold drawn steel bars:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Wide range of cold drawn steel bar sizes: from 10mm to 150mm
3) Different cold drawing medias powder or oil to get different surface
4) Straightening machines to get better straightness up to 0.5mm/m
5) Grinding and polishing machines to get better roughness upto 0.4um
6) Heat treating furnaces to adjust the mechanical properties
7) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
8) Multiple packages to avoid broken packages and anti-rusty
