Xichao Kangwei State Fifth Promotion and Wenzhou User Recognition
First of all, the promotion activity was kicked off in the speech of Ma Kehua, General Manager of Wenzhou Huama Company, followed by Gu Zhanfu, the manager of Shifeng Zhejiang Region, to do the presentation of wind products, and highlighted the advantages of Xichai State No. 490 without adding urea. At the same time, there were representatives of the users who spoke. The Xichai representatives also introduced the five advantages of Xichai 490.
This time, FAW Xichai mainly promoted Conway Five 490 products, it will use the country's six technology countries five to upgrade from the country four to the five countries still do not add urea engine, the use of cost reduction to save money more peace of mind; while active and passive regeneration The DPF post-processing technology complies with the regulations of the State Five and Beijing Five; the product structure is basically the same as that of the National IV, and the components are versatile, convenient and worry-free. At the same time, the launch of the 40,000 kilometer long oil change service of Xichai Kangwei also represents Xichai's guarantee of Conway quality.
Technicians give technical explanations
In the Wenzhou area, the company’s share of Wuxi’s five products reached 100%, which once again demonstrated the user’s recognition of the wind’s dumping and the five products of Xichai.
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
