FAQ:

Q1: How many tons of steel products could be loaded in containers?

A1: Usually the steel products are delivered by bulk vessel because of the large quantity and the freight. However, there are no bulk vessel enter some seaports so that we have to deliver the cargo by containers. The 6m steel product can be loaded in 20FT container, but the quantity is changed according to the size, usually from 18tons to 25tons.

Q2: what is the difference between actual weight and theoretical weight?

A2: All the section steel has two weights: actual weight and theoretical weight. Actual weight is the weighing out when the product delivered from the mill. Theoretical weight is calculated by pieces.  The invoice can be based on each of them as your request.

Q3: How soon can we receive the product after purchase?

A3: Within three days of placing an order, we will arrange production. The normal sizes with the normal grade can be produced within one month. The specific shipping date is dependent upon international and government factors, the delivery to international main port about 45-60days.

Q:Why not Rail Rail corrosion?
As the train passes, the constant rail friction with the wheel rust away.
Q:What is quenched rail?
Quenched rails are hardened when rails are finished, so the advantage is to increase the hardness of the rails
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:Why can't the blue after rail grinding
Therefore, when the need to control the rail grinding grinding speed, can not produce high temperature, to avoid the phenomenon of blue.
Q:The previous track is seamed, there is no gap, is how to achieve
Seamless rail not thousands of kilometers without gaps, but the 25 meter long rail welding up into hundreds of metres long or even thousands of meters long, and then in the shop on the embankment, or the gap between 11 mm and a section of a seamless rail, now Shanghai Nanjing line is 303 km long ultra long seamless rail. Seamless rail to solve the thermal expansion and contraction by slot number is not enough, now solve the thermal expansion and contraction in two ways: one is the long rail itself under all temperature stress, will be locked in the long rail sleepers, which is due to temperature change and contraction, this method is suitable for throughout the year the temperature is almost the same as in the southern region, Chinese. 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: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: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:Why can't the vertical rail bend the rail?
In order to solve this problem, the railway department within a certain distance, playing a few holes in the rail waist to release the energy generated by thermal expansion and contraction, and within a certain distance (about 1500m) retaining rail joint, to assist in releasing the energy generated by the thermal expansion and contraction, in order to solve the problem of rail expansion and contraction.
Q:How can the 25 meter rail be transported on the highway?
In accordance with the operation of large transport operations, the vehicle can not arrive, you can take towing, or 2 car vertical line to solve.
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.
