Usages of Steel Light Rail Q235B with Multiple Specifications:

Light rail is mainly used in forest region, mines, factories and construction sites laid of the place such as temporary transport line and light motorcycles with line. Be widely used for railway, subway, transportation track, express, curve way, tunnel way and so on.

Packaging & Delivery of Steel Light Rail Q235B with Multiple Specifications:

1. Packing: it is nude packed in bundles by steel wire rod

2. Bundle weight: not more than 3.5MT for bulk vessel; less than 3 MT for container load

3. Marks:

Color marking: There will be color marking on both end of the bundle for the cargo delivered by bulk vessel. That makes it easily to distinguish at the destination port.

Q:What is the connection of the rail joint?
A part that connects rails or rails and ties. The former is called joint connection parts; the latter is called intermediate connection parts. Its role is to effectively ensure the rail and rail, rail and sleeper between the reliable connection of long-term, continuous rail as soon as possible and integrity, prevent rail relative to the longitudinal movement of the sleeper, ensure the normal track, and give full play to the role of dynamic cushioning performance of vehicles, slow down the line of residual deformation accumulation.
Q:What is called orbital angle?
The rail must provide a continuous, smooth, and least resistant rolling surface for the wheel. In electrified railway or automatic block section, rail can also be used as track circuit. The rail can be divided into three kinds: crane rail (crane track), heavy rail and light rail.
Q:How to solve the problem of thermal expansion and cold contraction of railway rail?
The railway line to solve the rail expansion and contraction method is generally used for fastening the way, is the shrapnel into spring fastener fastener (also called spring bar fastener), rail tightly in the sleepers, forcibly will produce thermal expansion and contraction of the energy to digest, but the existence of such a problem is generated when the thermal expansion and contraction energy is greater than the distance unit of sleeper rail adhesion, makes up the phenomenon of rail, rail sleeper unit length twist.
Q:What kind of welding rod should be used for rail and Q235A welding?
MG600 is a universal, high efficiency, high strength chromium nickel alloy welding rod (welding wire). It has excellent plasticity, toughness and crack resistance. It is almost suitable for all kinds of common steel products. With excellent welding process performance, arc stability, easy to slag, less spatter, welding uniform and beautiful.
Q:What is the difference between Q235B rail and 55Q rail?
The two kinds of material rail is mainly carbon content difference, and the other is brittleness, toughness, tensile strength, impact strength are not the same
Q:How are the rail tracks worn?
Rail is the main component of railway track. Its function is to guide the wheel of the rolling stock, to bear the great pressure of the wheel and to deliver it to the sleeper. The rail must provide a continuous, smooth, and least resistant rolling surface for the wheel. In electrified railway or automatic block section, rail can also be used as track circuit.
Q:Why is the thermit reaction welded to rails instead of welded rails?
Steel contains other added elements, while the thermit reaction produces only iron.
Q:Is the rail of the railway made of steel? Or iron or iron?
Rail is a forging, steel and iron are essentially different from the amount of carbon content. The carbon content of steel is 0. 0218%-2. Between 11%, the carbon content of the cast iron is 2. 11%-6. 69%.Such as a rail model is: 60U71MN, the rail belongs to manganese steel 60, indicating that the weight is 60KG/mU71 means 0.71% carbon content
Q:What's the difference between a hot rail and a heat treated rail?
Surface heat treatment, such as surface hardening. There is still a difference, but for the same material, heat treatment is the same.
Q:What is the connection mode of the return cable on the rail?
Current transformer installation should pay attention to several points: one is the two circuit transformer is not allowed to open, to prevent the generation of high voltage induction harm, two is the two circuit grounding point, three is the current level of transformer should be greater than or equal to the maximum current in the main circuit, otherwise will exceed the current table
