Packaging & Delivery of Hot Rolled Mild Heavy Steel Rials for Minas GB, AREMA, DIN Standard

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

Heavy 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.

Q:The rails of the high iron welded together as a whole
Seamless welding technology, can make between two rails almost can not see the welding point, natural transition, in the high-speed rail, "bang" sound will become history.
Q:How do seamless rails solve thermal stress problems?
In the laying time, according to the laying of long-term local meteorological data, calculate a fit temperature and corresponding stress, during the production of rail, the rail using tensile data properly, the internal rail leaving a stress. In this way, even if the rail is stretched and contracted, it is only offset with the original stress, so as to ensure the expansion of the rail within the controllable range
Q:What is called orbital angle?
It is a major component of a 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.
Q:Contact surface between train wheel and rail
Because the wheels of the train all have rims, you can go and have a look at it, that is, a part of the inside of the wheel. The main function of this wheel flange is to guide and prevent derailment. The rim has a very complex profile. The standard requirement is that if the flange of a car is too worn out, it is prone to derailment. The machined flange must be machined to the standard contour.
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 the function of a railway joint connection part?
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 are the three types of rail damage?
Rail damage has always been a key problem in railway transportation. The main damage types are rail crush, side wear, corrugation and delamination, accounting for more than 80% of the rail damage.
Q:What are the requirements of the two rails on the track?
Gauge requirements, linear standard gauge is 1435mm, curve can be properly widened.
Q:Seamless rail is not afraid of expansion and contraction?
Seamless rail is also afraid of thermal expansion, cold contraction, but better than ordinary steel pipe. Thermal expansion and contraction are the laws of physics. When heated, the distance between molecules increases, and the rails extend. Similarly, cold contracts.
Q:What is the cause of the side or rail end of the rail? If not timely remediation, what will easily lead to consequences?
Simple and straightforward to say: rail by lateral, vertical long-term pressure fatigue, make rail deformation deformation, so that the profile of horizontal widening, that is, fat edge.
