The continuous increase in the cost of vehicles has forced people not to miss the details of any savings. Tires are actually a consumable item that costs a lot during the car's use. Four tires are worth several thousand yuan. If they are used improperly, they will cause abnormal wear and tear. It is also a test for owners' wallets. How to reduce the wear of tires and make tires useable? Lifetime maximization is the knowledge that car owners must master. Good and skilled driving techniques can effectively reduce tire wear, extend the life of the tire, and improve driving safety. Insufficient or too high tire pressure can easily lead to puncture "The high speed must be to refuel the tires." Many riders believe that the high speed should be full of gas, the car has "strength" to run high-speed, "but in fact, this idea is wrong. Tire pressure High, will reduce the contact area between the tire and the ground, and at this time the pressure on the tire is relatively increased, the tire's grip will be affected, coupled with the vehicle through the groove or bumpy road, the tire does not have enough space to absorb the vibration, In addition to the impact on driving stability and ride comfort, it will also increase the impact on the suspension system, which will also bring harm. When the tire pressure is lower than the standard value, the tire shoulder wear increases sharply; when the tire pressure is higher than the standard value, the tire ground contact area decreases, the unit pressure increases, so that the middle tire tread wear increases, while increasing the tire rigidity Therefore, the dynamic load on the wheels is increased and the carcass bursts easily. Do not start too fast. Avoid frequent use of brakes and emergency brakes to avoid accelerated tread wear due to tires and ground dragging; proper control of turning, passing, passing through intersections, narrow roads, railroad crossings, etc. Speed ​​and pay attention to the dynamics of roads, pedestrians, and vehicles, prepare for braking, reduce frequent braking, avoid emergency braking, and thus reduce tire wear; if you face cullet or other foreign objects that cannot be avoided, you must slow down and pass through. Do not slam the brakes, because the brakes cause the pressure to increase, and glass fragments and foreign objects can get into the tire more easily. Check the tread for cracks “I have a glass tie on the side of my tires. Is there any problem with high-speed running?†asked the owner. 4S shop staff introduction, the tire side of the injury, the insurance factor can not be guaranteed, because the side of the tire is basically no steel wire, the tire wall is very thin, high-speed easy to puncture. Regularly check the tire surface for cracks, deformation, and other defects. The groove of the tire gradually becomes lighter due to wear and tear. If it wears flat, it will lose the effect of drainage and slippage. The performance of the car will be greatly reduced, and the seemingly small cracks are the hidden dangers of puncture at high speeds. Pay attention to remove small stones in the groove in time. Avoid parking your vehicle on rough, sharp or sharp stones. Vehicles should not be parked near or in contact with petroleum products, acids, or other materials that affect the deterioration of rubber. The driver should not turn the steering wheel after parking. Such operation will accelerate the wear of the tire. The tires tend to overheat in the summertime when they are driving for a long time or when they are driving at high speeds, and the air pressure increases. At this time should stop cooling, is strictly prohibited deflation pressure or splash water cooling, to prevent the abnormal aging of the tread rubber. Usually pay attention to the good habits of the road than usual maintenance When driving on the highway maintenance construction site, apply a slow-moving method to select the road surface to avoid excessive impact on the tires, or even be stabbed or scratched; on a bumpy road, one must select the road surface to reduce the tires and the road surface. Strike to avoid mechanical and tire damage; Second, slow down to avoid tire bumps and strong vibration; Through the muddy section, should choose a more solid, non-slip place to pass, so as not to tire subsidence, idling, severe heat Severe cuts and scratches on tires and sidewalls. The turning of the vehicle should be based on the curved road conditions and the turning radius. Generally, the speed should be decelerated appropriately to avoid acceleration of unilateral tire wear due to inertial force and centrifugal force. When the vehicle is descending, appropriate speed should be controlled according to the size, length and road conditions of the slope. This can avoid or minimize the use of emergency braking to reduce tire wear; vehicles parking on the way and stop at the stop should develop the habit of safe gliding. In the maintenance and use of tires, do not forget the most important tire - spare tire. Reserve tires are factory-fit, but they are often forgotten by the owner and lack maintenance. It is recommended that the owner periodically check the spare tire every 3 months and inflate it if necessary so as not to find it flat when it is needed. 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
