Applications of Steel Light Rail wfith High Quality for Construction:

Light Steel 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, for example:

railway, subway, transportation track, express, curve way, tunnel way.

Package & Delivery of Steel Light Rail wfith High Quality for Construction:

1. Package: 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.

Tag mark: there will be tag mark tied up on the bundles. The information usually including supplier logo and name, product name, made in China, shipping marks and other information request by the customer.

If loading by container the marking is not needed, but we will prepare it as customer request.

4. Transportation: the goods are delivered by truck from mill to loading port, the maximum quantity can be loaded is around 40MTs by each truck. If the order quantity cannot reach the full truck loaded, the transportation cost per ton will be little higher than full load.

5. Delivered by container or bulk vessel

6. Delivery Time: All the Hot Rolled Steel Rail will be transpoted at the port of Tianjin, China within 30 days after receiving the advance payment by T/T or the orginal L/C at sight.

Production flow of Steel Light Rail wfith High Quality for Construction:

Material prepare (billet) —heat up—rough rolling—precision rolling—cooling—packing—storage and transportation

FAQ:

Q1: How do we guarantee the quality of our products?

A1: We have established an advanced quality management system which conducts strict quality tests at every step, from raw materials to the final product. At the same time, we provide extensive follow-up service assurances as required.

Q2: How soon can we receive the product after purchase?

A2: Within three days of placing an order, we will begin production. The specific shipping date is dependent upon international and government factors, but is typically 7 to 10 workdays.

Q3: What makes stainless steel stainless?

A3: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q:What kind of welding rod should be used for rail and Q235A welding?
Application: suitable for welding tools and moulds, high-speed tool steel, hot work tool steel, steel, cast steel, T-1 steel, steel, vanadium steel, seismic spring steel, martensitic stainless steel, austenitic stainless steel, ferritic stainless steel, and the unknown as well as between the various different types of steel welding etc.. Such as high pressure valves, broken bolt clearance, shaft transformation, etc., the effect is very satisfactory.
Q:Why should there be a gap between the two railway tracks?
Another relatively new way of connecting rails is the continuous welded rail (Continuous, Welded, Rail, CWR), also known as seamless rails or long welded rails. This method couples several kilometers of rails together to form a continuous line. Because there is no seam, the strength of the track increases, less maintenance is needed, and the vehicle runs more smoothly.The cost of welded rails is more expensive than that of a fish board. But because of the high strength, the vehicle can travel at a higher speed on the continuous welded track, and the friction force is reduced.
Q:Why should there be a gap between the rails?
Because the rail will be affected by the environment, thermal expansion, cold contraction, if there is no gap, then the rail heating expansion, will track extrusion deformation.Solving the problem of thermal expansion and cold contraction of track is one of the main aspects. Secondly, it is convenient for laying and maintenance.
Q:Why are the rails made of I-beam?
H section steel is a kind of economical and economical surface profile (other cold bending thin wall steel, pressed steel plate, etc.). Because of the reasonable cross-section shape, they can make steel more effective and improve the bearing capacity. Unlike ordinary I-beam, the flange of H steel is widened, and the inner and outer surfaces are usually parallel so that it is easy to connect with high strength bolts and other components. The size of the series is reasonable, the model is complete, easy to design and use.
Q:Which companies are the main rail products used in China?
There are four major rail and beam factories in China, namely Panzhihua Iron and Steel Group's rail beam factory, Anshan Iron and Steel Group Anshan Iron and steel works, Wuhan steel rail beam factory and Baotou steel rail beam factory.
Q:What is the function of a railway joint connection part?
The intermediate connecting parts, also called fasteners, have different combinations according to the different types of sleepers used. The wooden, including ordinary spike and iron plate. The advantage of this kind of fastener is less parts, easy installation, but little effort. In order to improve the performance of wooden, many countries use screw spike or spring instead of ordinary spike spike, or use a variety of different types of fastener on the concrete sleeper has been effective. The concrete sleeper fastening, including anchor bolts, iron plate, fastening piece and an elastic cushion (a) anchor bolt. For fastening fastening parts by anchoring various methods. The use of China on the railway is a sulfur anchor mix of sulphur, sand, cement and wax mixture is melted into colloid, injected into the reserved hole in the sleeper, as the fixed anchor bolt medium, pulling resistance, durability and insulation performance are very good. (b) iron backing plate. The utility model can disperse the vertical pressure of the rail, and after adding the shoulder, the transverse force transmitted by the rail can be partly taken, but because the compressive strength of the concrete sleeper is very large, the utility model can not be arranged in general. (c) fastening parts. There are two types of rigidity and elasticity. Rigid fastening parts mainly for buckle type; elastic fastening parts are spring and bar use plate elastic strip type two. (d) elastic cushion. When the train passes, the utility model can buffer and reduce vibration, and can improve the insulation performance of the concrete sleeper. Rubber backing plate, plastic backing plate, cork rubber backing plate and wood backing plate etc., and rubber backing plate is the best.
Q:High iron seamless rail is how to solve the problem of the thermal contraction account?
The seamless line is divided into a fixed area, expansion area, buffer, the buffer can be reserved for the large number of rail joints for expansion, expansion area adjacent to the buffer, if the buffer rail gap due to seasonal changes is not enough, the rail to replace the different length in the expansion area to adjust the rail gap.
Q:Why should there be a certain gap in the rail connection?
No, it's expansion and contractionMainly because the track is made of steel, it will heat up and contract cold.If you don't sew it, it will break in summer.But now the latest technology can be used in other ways to overcome the heat up cold contraction effect, as seamless.
Q:What's the difference between a high-speed rail and an ordinary one?
Rail section and weight are the same, generally 60 rail, 60.64kg meters per meter weight, high-speed rail rail is mainly material, better than ordinary rail, more wear-resistant.
Q:What is the method to check the straightness of rail?
The straightness error can be measured by means of flat crystal, laser interferometer and straightness measuring attachment, and the measurement accuracy is very high.
