Packaging & Delivery of Ms Heavy Steel Rai 50Mn, U71Mn

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

Ms Heavy 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.

5. Delivered by container or bulk vessel

Q:Can a track circuit stand between two rails without getting an electric shock?
If the electric two rail, rail, sleeper and ground are insulated, people do not contact track, not electric shock, no "step voltage. If the insulation is not good, the ground has power, it would have to waste much power, is a great waste.
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:Why can't stainless steel be used as rail?
Stainless steel prices are high. Of course, the cheaper the rail, the better. The price of stainless steel is about 3 times of that of iron
Q:What kind of steel should be used for railway rails?
At present, foreign timber rail basically is pearlite steel, while the rail strength can be increased by alloying and heat treatment technology, but is close to the limit, cannot be solved in improving the strength while maintaining good toughness from the root of the problem, more unable to meet the requirements of high speed and heavy haul railway on rail and rail turnout is higher and the technology. Bainitic steel is the invention patent of Professor Fang Hongsheng of Tsinghua University. In 2005, it was coordinated by Baotou science and Technology Bureau to promote cooperation between Baotou Steel and Tsinghua University. It was listed as a key research cooperation project in Baotou. The bainitic rail solves the technical problems of strength, toughness, plasticity and processability simultaneously meeting the requirements. The operation test of Shenyang Bureau, Shijiazhuang Taiyuan line, Beijing Baotou line, Daqin Railway Line in recent years proved that the bainite rail turnout rail turnout than the strength can be increased more than 2 times, the toughness can be increased more than 4 times, life can be increased more than 3 times. In October last year, the Ministry of Railways organized the "railway heavy rail bifurcated rail structure and material optimization research" bidding project, Baotou Steel won the bid at an absolute advantage. The next step is to generalize to curve rail, combined turnout rail and other varieties, and the economic and social benefits will be more remarkable.
Q:Why can't the blue after rail grinding
Blue is produced martensite, which is a kind of brittle microstructure, high magnification can be found between the metal particles Never mind, cannot form a fibrous structure, will cause the brittle fracture of the rail, there is a big security risk.
Q:What is the connection of the rail joint?
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:Why should there be a gap between the rails?
After laying the rails, the wood seems to swell and the rails will jump up.To prevent the heat from rising and cold contraction, the two rails have strong pressure on each other, thus damaging the rail. So there must be a gap between the rails.
Q:Why are some city railways called light rail? What is heavy rail?
The rail is divided into two kinds of heavy rail and light rail. The rail specification is expressed by the nominal weight per meter.Heavy rail: the nominal weight of more than 30 kg per meter, rail belongs to heavy rail, heavy rail is divided into general rail and crane rail two. General rail means rail laying, dedicated lines, bend and tunnel rails. Among them, the standard track length is 12.50 meters and 25 meters in two, the laying of the curve rail, slightly shorter length, 12.46 meters, 12.42 meters and 24.96 meters, 24.92 meters and other rail, general specification for 38, 43, 45, 50, 60 (kg / m).
Q:Will seamless rail expand and shrink?
In Qin Shen guest is also equipped with telescopic regulator, but also can prevent expansion and contraction caused by distortion of the track, but the train through the telescopic regulator will still produce vibration, affecting comfort.Sometimes the temperature range is too large may also be in the winter and summer transition to release stress release fastener.
Q:What's the difference between a hot rail and a heat treated rail?
The hot rolling is equivalent to the annealed state, while the heat treatment is divided into many kinds, the whole heat treatment, annealing, tempering, normalizing, quenching, chemical heat treatment, carburizing and nitriding;
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.
