20-kilometer-long slope Fast reversal escort for heavy truck drivers

The fast sales of Fast Retarder in the market have been frequently reported. Recently, after supporting some users in northern Shaanxi, there were dozens of hydraulic retarders that were used as supporting vehicles for hazardous chemicals in Shanxi and high-end logistics vehicles in Sichuan and Chongqing. They continued to heat up in the markets of Shanxi, Sichuan and Chongqing. Has become the standard of many heavy trucks, the driver's heart "safeguardian."

Installation of hydraulic retarder delivery ceremony

On November 19th, 2016, at the delivery ceremony for dangerous chemicals transport vehicles in Shanxian County, the person in charge of Ascendas Transport stated that the company was mainly engaged in the transportation of hazardous chemicals, taking into account the special nature of the transportation of hazardous chemicals. A total of 17 vehicles were equipped with Fast Retarder. Fitting a FAST hydraulic retarder allows every driver to feel at ease.

Adding hydraulic retarder process

Master Zhong Zhong, a customer in Chongqing, praised the superior safety braking performance of Fast Reactor Hydraulic Retarder. He purchased Jieshi 480 horsepower, mainly running from Chengdu to Tibet, and the cargo load rating. â€œFastite hydraulic retarder gave me the greatest feeling of safety and economy.â€ He said that when no hydraulic retarder was installed before, the long slope of the next 20 kilometers was frightened and he feared that the brakes would fail. Now equipped with a FAST hydraulic retarder, there is no pressure to run downhill at 60 km/h. Not only save the cost of adding water, but also the replacement of the brakes hub, brake pads, tires, the number of tires less, and save a lot of money.

Fast FH series retarder

Hydraulic retarder is a new generation of automotive brake products tailored for heavy trucks and equipped with independent intellectual property rights. It fills the gap in the domestic market and breaks the intellectual property barriers established by multinational corporations. It is a key technology and core technology. It has reached the international advanced level and its superior retarding performance fully meets the development needs of heavy-duty gears, large tonnages, large horsepower, and high-speed development, as well as the individual needs of different users, for passenger cars, medium and heavy trucks, and special vehicles. Vehicles provide reliable safety protection and efficient deceleration braking. During the R&D process, Fast's hydraulic retarders have been subjected to harsh natural environments, conditions, and road conditions such as high altitudes, high temperatures, high temperatures, and long-distance sections, and the performance indicators are far higher than national standards. With the advantages of advanced design, high performance-to-price ratio, and high security, it has become the "safeguardian of safety" for heavy truck drivers.

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.

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
