All participants On July 1, 2015, Voith Asia Pacific Business Function Center was officially established and put into operation in Kunshan. At the celebration of this first anniversary, the heads of corporate function centers in the Asia-Pacific region not only helped employees to interpret the operation status in detail, but also focused on reviewing the achievements in the region and the work processes of various functional departments during the year. It also collected the problems and feedback that employees encountered in their daily work.
Voith released its interim report for the 2015/16 fiscal year last month. The business performance of the Group's business units has grown, and the pace of transformation has steadily advanced. “Although the economic environment in the current fiscal year is full of challenges, we are still advancing steadily and implementing our projects step-by-step in an orderly manner. In a market environment full of challenges and lack of economic growth, all the Group's business units have made great progress. Excluding the impact of unconventional projects in the first half of the year, the Voith 150+ Success Plan we implemented throughout the Group is achieving results. The Voith Group's basic profitability has improved significantly.†Group President and CEO Dr. Berth Limhard said in his presentation on the overall development of the group during the first half of the fiscal year
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
