In order to reflect concentration and specificity, Xiao Bian will only know about science and turning lights. The turn signal, as the name implies, is used during steering to convey important indicators of vehicle dynamics to the outside world, so that the surrounding vehicles and pedestrians know the movement of the vehicle and make appropriate correct judgments and measures. It also guarantees traffic safety to a certain extent.

However, with regard to the knowledge of the turn signal, it is only known to turn left to change lanes to the left and to change lanes to the right. However, it has many other uses, such as:

When driving around the island

Do not play lights when entering the roundabout. Hit the right light when leaving the roundabout. Because you have to walk down the road when you enter the roundabout, you don't need to play lights, but you must slow down. The purpose of driving the right turn signal when leaving the roundabout is to remind the rear and opposing vehicles. This is a clear rule of the new rules. Many drivers used to turn left when they entered the roundabout. In addition, we must pay attention to the enthusiasm of driving, driving in the roundabout should be based on the principle of first-in, first-out, not strong, safe driving is the most important.

Steering lights grab car parking spaces

Nowadays parking has become a common problem in the city. When we circle around the parking lot, it is hard to find a parking space. It is preparing to stop, but I don’t know that the guy who doesn’t know where to come from. Stopped, this time wait for them to come down to find them to fight a is not, in fact, this time turning lights come in handy!

When driving at high speed

Turn on the left light when entering high speed, and hit the right light when leaving high speed. Because entering high speed is turning left and turning away from high speed is turning right. Driving on high speed should pay more attention to safety, I believe this one will still be used frequently. In the same way, when you enter the main road, you will turn left, and from the main road, you will turn right.

Postscript: Although the turn signal is only an accessory on the car, it is also an elegant point of communication. It is also a bridge for you to communicate with other vehicles. Communication is not barrier-free, and it will not cause accidents to block yourself and others.

Cold Drawn Steel Bar

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.

According to different steel grade, the production line is usually different. The Basic production line is as below:

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
