The demand for heavy metal monitoring instruments and instruments increased investment in atmospheric and water quality monitoring. Heavy metal and soil monitoring were included for the first time, and environmental monitoring instrument industry growth was determined. The cleansing factor for total discharge control of cleansing substances during the “Twelfth Five-year Plan†period will be increased from two items to four items. The comprehensive management of drinking water safety and air purification will continue to increase, and inventory requirements related to atmospheric and water quality monitoring instruments will increase. Growth determined. The purification of heavy metals and soil purification were initially focused on policies. From the State Council to the Ministry of Environmental Protection and then to local governments, the input for comprehensive management will soon gradually enter the implementation level, confirming the incremental demand growth associated with heavy metal monitoring instrumentation.
The market for heavy metal and soil monitoring instrumentation is promising. Market competition for atmospheric and water quality monitoring instruments is fierce, and the market for heavy metal and soil monitoring instruments is just beginning. From the list of qualified products released by the China National Environmental Monitoring Center and the list of companies inspected, there are many market participants for existing atmospheric and water quality monitoring instruments. The industry competition is fierce. For example, as of February 24, 2011, the chemical oxygen demand was automatically detected online. There are 55 manufacturers that have passed the certification and testing of qualified products. As of February 12, 2011, there have been 45 qualified manufacturers of fume smoke continuous automatic monitoring and system certification. In February 2011, the State Council formally approved China's first “Twelfth Five-Year Plan†special plan “The 12th Five-Year Plan for Integrated Prevention and Control of Heavy Metal Decontaminationâ€; in April 2011, the Ministry of Environmental Protection issued the 2011 “National Essentials for Decontamination Prevention and Controlâ€. The primary obligation is to "put in heavy fists and use heavy codes to ensure that the "12th Five-Year Plan" for the "Comprehensive Prevention and Control of Heavy Metal Decontamination" is a good starting point"; although short-term top-down policy drivers are difficult to reach at the implementation level, For the time being, we are optimistic about the country’s strong investment in comprehensive prevention and control of heavy metals and soil purification.
The government's efforts to strengthen environmental supervision will bring new opportunities to the environmental protection instrumentation industry. It will also intensify the competition in the industry. When major companies face both opportunities and challenges, the only way to enhance their competitiveness is to achieve long-term expansion. .
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
