High Quality Steel Rail

Applications of High Quality Steel Rail

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.

Heavy rail is suitable for the laying of main trunk line of the curves and the orbit of the tunnel can also be used for tower crane and other crane track.

Packaging & Delivery of High Quality Steel Rail

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

High Quality Steel Rail

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.

High Quality Steel Rail

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.

7. Invoicing on theoretical weight or actual weight as customer request

8. Payment terms: 30% advance payment by T/T, 70% payment against the copy of the B/L; 100% L/C at sight, etc.

Inspection of High Quality Steel Rail

We will send the MTC of the factory to the clients directly which contains the anlisis of the heat, chemiqual composition, phisical characteristicas, etc.

And our inspectors will arrive at the factory to meke the inspection of the size, length, weight and quantity before the transportation from the factory.

Q:What is the method to check the straightness of rail?
The measurement accuracy of the latter is up to 0.4 microns /1000 mm. Straightness measurement is mainly to measure the straightness error of cylinder and cone, the guideway of machine tools and other machines, and the straightness error of the workpiece's linear guide surface.
Q:High iron seamless rail is how to solve the problem of the thermal contraction account?
There is a direct relationship between changes due to temperature stress in CWR under the size and temperature of rail, so we locked rail must be correct, reasonable selection of locked rail temperature, to ensure the CWR winter break, summer is not caused by track swelling, endanger traffic safety.Seamless rail to solve the heat up, cold contraction, light by a small number of cracks is not enough, and now solve the heat up, cold contraction, there are two ways. One is the long rail itself to bear all the temperature stress, the long rail is locked on the sleeper, so that it does not shrink due to temperature changes. This method applies to areas where the temperature varies slightly throughout the year, for example in southern china. In some temperature difference regions should take another approach, namely the long rail itself does not bear the temperature stress, and stress or regular bleeding stress to automatic bleeding, make the long rail with temperature rise and free shrinkage, at the time of laying also try to choose the best temperature of laying the rail expansion value in the minimum range, so that regardless of temperature rising or falling, the rail expansion always control in the smallest range.
Q:How are the rail tracks worn?
Two methods:1, the rails will be melted recast.2. Make rail into other landmark buildings.Note: old rail should be prepared after the public security reported.
Q:What is quenched rail?
. In the past, the heat treatment of the rail head was made by high frequency induction heating or flame heating to 850~900 degree Celsius, and then quenched at 600~650 C for tempering at high temperature to obtain the structure of tempered bainite.
Q:Why is the thermit reaction welded to rails instead of welded rails?
Yes.Rails and rails are similar concepts. Steel is iron with very little carbon content.
Q:60 detailed dimensions of rail
The type of rail is expressed by the mass kilogram of rail length per meter. The rails used in China's railways are 75kg/m, 60kg/m, 50kg/m, 43kg/m and 38kg/m.
Q:Why does the train not skid on the rails?
But in the actual operation, locomotive could slip, which is mainly due to the change of external conditions, the formula is in good condition to face, if there is oil, cream, water and other impurities on the track, or line quality is not good, may also be part of the locomotive itself result, the adhesion coefficient will decrease, when the locomotive traction motor traction play may be greater than the adhesive force, formed the so-called idle, the locomotive is harmful and must be eliminated quickly. Generally use sand to increase adhesion coefficient, no, then the locomotive will reduce load, reduce traction.
Q:Why is the railroad track free of expansion joints now?
Buy high iron, steel reinforced insulation insulation card _ tie rail (cross word type), hot melt gasket (can also be used for vegetables piperoof construction), SK--2 type rail protection cover, telescopic tube, screw cap protective cover.
Q:What is a rail flaw detector used to detect?
JGT-2 type rail flaw detector is usually used for flaw detection. The horizontal probe is mainly detected by a straight probe, and the smaller inclined crack can also be found. In the detection, the probe is placed on the rail surface and the defect is judged by the presence or absence of the bottom wave of the rail. When no bottom wave is indicated, the flaw detector sends out an alarm signal. There are no defects in rail, bottom wave. When there is a horizontal defect, there is a defect wave, no bottom wave. When there is an inclined crack, the defect wave decreases or disappears, and there is no bottom wave. If there is a horizontal or inclined crack near the screw hole, there is a screw hole reflection and defect wave, but there is no bottom wave. The part of the nuclear damage available 50 degree oblique probe, available before and after the screw edge inclined crack and waist 35 degree oblique probe, the rail weld with double 35 degree oblique probe.
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
WING,a famous enterprise specializing in the production and sales of hot rolled hexagonal steel, flat bar and steel rails. Since the establishment of our company, we have been devoted to setting up a good CIS.
