The Development and Reform Commission's Central Resources Department convenes a "limited plastic" work summary meeting

On December 3, in order to implement the Circular of the General Office of the State Council on Restricting the Use of Plastic Shopping Bags for Production and Marketing (hereinafter referred to as the “Limited Plastic Order”), the Department of Environmental Resources held a summary meeting of “limited plastics” and all relevant departments notified In the past two years, the relevant circumstances of the "Special Plastics" special inspection and related work carried out after the "plastic limit order" was issued. In response to the problems reflected in the implementation of the “plastic limit order”, the participating departments focused on the next step of the work and put forward practical suggestions. In 2011, the relevant departments will continue to promote the implementation of the “plastic limit order” from four aspects: continuously increasing propaganda, joint departmental joint special law enforcement inspections, implementing local government responsibilities, and improving the policy system, and further consolidate the achievements of “limited plastic”.
Ministry of Information of the Central Propaganda Department, Department of Social Development of the Ministry of Science and Technology, Energy Conservation Department of the Ministry of Industry and Information Technology, Ministry of Finance of the Ministry of Finance, Department of Pollution Prevention of the Ministry of Environmental Protection, Department of Commerce of the Ministry of Commerce, Department of Politics and Law of the State Administration of Taxation, Department of Industry and Commerce of the General Administration of Industry and Commerce, General Administration of Quality Supervision, Inspection and Quarantine The relevant law enforcement department responsible comrades attended the meeting.

Heat Treated Steel Bar And Tube

HEAT TREATED STEEL BAR AND TUBE

Heat treated steel bar is produced by heating and cooling in different temperature based on the steel grades to improve the steel bar mechanical properties or machinability for various industrial applications. Heat treated steel bar includes annealed steel bars, Normalized Steel Bar, quenched and temper qt steel bar.

Annealed Steel Bar has better ductility and lower hardness, which can be easier to be machined. The annealing processing is usually widely used for steel grade with higher carbon content above 0.5%. However, some low carbon steel also requires to do annealing for special usage such as 20CrMnTi gear steel. For some special material such as 20CrMnTi gear steel and GCr15 such bearing steel, spheroidizing annealing is often required.

Normalized steel bar sometime is also one kind of annealing processing. It mainly changes the grain to remove the impurities in steel and improves the strength and hardness. For some hot rolled steel bars, to keep the basic mechanical properties, normalizing is often used.

Quenching and Tempering, abbreviated as Q&T is a king of processing that strengthen or harden steel bars by heating the materials and then cooling in water, oil or other liquid medium, that rapidly the change from austenite to perlite to get the proper properties for various usage. The quenched & tempered steel bar materials are usually with carbon from 0.30% - 0.60%, it is widely used as merchant bars in components of various machines.

Our advantages on producing heat treated 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
