Zhongjiao West built J series mixing equipment passed the technical appraisal of the Ministry of Communications

On November 1, 2008, he was chaired by the Department of Science and Technology Education of the Ministry of Communications, Liu Jiazhen, Vice President of the Research Institute of the Ministry of Communications, Wang Wuqin, General Manager of the Science and Technology Department of China Communications Technology, Professor Jiao Shengjie, Dean of the School of Engineering and Mechanics of Chang’an University, and Professor Feng Zhongxu of Chang’an University. Dr. Yang Donglai, chief engineer of Guangdong Changda Highway Engineering Co., Ltd., Xie Liyang, deputy director of Xi'an Road Construction Machinery Testing Center, and Ren Shuozhe, deputy general manager of Shaanxi High Speed ​​Mechanization Co., Ltd., composed of seven experts from the country, and their counterparts in Xi’an The products of the JL Machinery Co., Ltd. - J series forced intermittent type asphalt mixing equipment project were technically appraised.
J-Series Container Asphalt Mixing and Mixing Equipment is based on the introduction of the advanced technology of Germany BENNINGHOVEN Company and uses other leading technologies from home and abroad for reference. It also independently develops and manufactures according to the requirements of domestic transportation, hoisting equipment and construction conditions. A series of products produced. It adopts modular structure of container, no basic design, convenient transportation, installation, and disassembly; has developed burners suitable for multiple fuels, expands the scope of fuel use, and is environmentally friendly and energy-saving; the system is stable and reliable, with low noise and low energy consumption; The secondary weighing, the position of the small door can be arbitrarily controlled, the weighing accuracy is high, and it can meet the accurate weighing of various gradations. Specially designed insulation layer is adopted to ensure the temperature stability of the finished product and the energy saving effect is significant. Since it was put on the market, it has won unanimous praise from the industry and users, and many sets of equipment have been exported overseas.
After the committee conducted data review and field trips, it was assessed that this series of equipment has advanced technology, reasonable design, reliable work, and overall reached the international advanced level. The J-Series Container Asphalt Mixing Equipment of China Jiaoxi Xiji Corporation successfully passed the Department of Science, Technology and Education of the Ministry of Transport. Technical appraisal.

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.

Qt Bar 

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
