Light Steel Rail Good development

The development of light rail is getting faster and faster

As China's manufacturing industry is growing faster and now basically from the development of fast, into a good development, out of some high consumption, low capacity of some enterprises, including some iron and steel enterprises, for the refined steel business is very good A phenomenon.

Before the short time, according to the news that, as the light rail railway development technology is getting better and better, basically as long as the use of light rail railway place, have some results, we know that the robot is by mechanical plus metal plus some Comprehensive knowledge, which can not be light steel rail grinding robot.

From the above to get light and steel development is very fast, and now technology development, for light rail railway, light steel and some of the grinding and cleaning has changed from a simple artificial into intelligent mechanization.

Our long-term supply of light rail railway sales, used in a variety of rail cars, or the better the effect of power cars, stability is getting better and better, welcomed the need to come to consult light rail railway related business.

Tell you 3 strokes effectively reduce the damage caused by light rail railway

Light rail railway frequency is relatively large, the damage is not avoided, you want to reduce the damage to light rail railway, it is necessary to take appropriate measures in a timely manner, each case to take the appropriate countermeasures for processing, as follows:

When the light steel railway nuclear injury is the most effective way to control the cooling of steel to avoid light steel within the railway due to hydrogen escape and produce small cracks, from the fundamental elimination of nuclear injury caused by the source of fatigue. Despite the various precautions, the new light rail nuclear injury still can not be absolutely avoided. In order to ensure the safety of traffic, it is necessary to carry out regular inspection of light and steel railways in order to eliminate hidden risks in time to avoid major traffic accidents. When used as a temporary measure, you can use the curve of light steel rail side of the oil or in the small radius of the curve laying high wear resistance of the special alloy light steel railway.

The main measures are to improve the design of the bogie for locomotives and vehicles, so as to improve the interaction between wheel and rail and reduce the friction between them.

Often to light steel railway inspection, found that the situation at any time to take measures to eliminate hidden dangers. Light steel is to guide the wheels of the vehicle forward, to withstand the enormous pressure of the wheel, light rail must provide the wheels for continuous, smooth and resistant to the smallest rolling surface. In the use of light and steel railways are often subject to wear and tear, good light rail railway with you to understand the light rail contact fatigue damage.

Resulting in light rail railway contact fatigue damage can be divided into three stages:

1, light steel tread surface shape changes, light steel rail tread appears uneven, the weld appears saddle wear, will increase the impact of the wheel on the impact of light rail railway.

2, light steel and railway joints contact fatigue formation, because the metal contact fatigue strength is insufficient, the maximum shear stress point exceeds the shear yield limit, will make the point into the plastic area.

3, light steel rail surface metal damage, due to the cold hardening of the metal, the head of the face of the hardness will continue to grow, the total mass of 150 ~ 200mt, the formation of micro-cracks in the head surface. Control the shape of debris. The use of hardened steel rail, the development of high-quality heavy rail, the reform of the old track re-use system, the rational use of light rail; rail steel material classification and so can reduce the light rail railway contact fatigue damage.
