Zhang Xinxin stated that since the issue of shortage of diesel fuel is still unclear whether it is a long-term problem or a short-term problem, the internal research of the public will continue. Volkswagen is studying whether the domestic schedule of diesel engines should be postponed. On April 24th this year, after the meeting of the 2008 International Advanced Diesel Engine Technology Symposium, Zhang Yuxin disclosed that Volkswagen is preparing to build a domestic diesel engine production line in China, and it will be completed and put into operation in 2010 at the earliest. Previously, due to oil quality problems, diesel vehicles have been subject to many policy restrictions. There are few followers of diesel cars in China. However, diesel technology is a strong point for the general public and is also a near-term route for its new energy vehicle program. As a result, Volkswagen spared no effort in promoting the development of diesel vehicles and lifting the ban on policies. Volkswagen has set a target to achieve 5% diesel vehicles sales in China in 2010. However, Zhang Xinxin said on that day that due to these uncertain circumstances, the 5% target in 2010 may change. Tungsten Carbide Roll Rings, also known as hard alloy roller ring, has been widely used in the rolling production of high-speed wire, bar, threaded steel, seamless steel pipes, etc. due to its good wear resistance, high-temperature hardness, heat fatigue resistance, thermal conductivity, and high strength.

The Tungsten Carbide Roll Rings we produce mostly come in two series: WC Co and WC Co Ni Cr, with Co and Co Ni Cr as binders ranging from 6wt% to 30wt%. From a usage perspective, hard alloy rollers have good comprehensive mechanical properties, with a bending strength of over 2200 MPa and an impact toughness of (4-6) × At 10 ^ 6J/m ^ 2, the Rockwell hardness (HRA) can reach 78~90. During the high-speed wire rolling process, the single groove steel passing amount is much higher than that of cold hard cast iron or high-speed steel rollers.
Volkswagen diesel domestic plans face variable or will be postponed
On July 21, after the publication of the Volkswagen Sustainability Report, Zhang Jianxin, vice president of Volkswagen China, revealed that due to the recent shortage of diesel supply in the domestic market, Volkswagen China is internally analyzing and evaluating the plans for domestic diesel engines that do not need to be changed.
