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:What are rail insulated joints used for?
The signal light will turn red this section car train to the next junction under light insulation is red and just turned yellow if lots occurred even then this section of the electric lights will turn red this belongs to the accident the driver will stop insulation
Q:U71Mn what does "U" mean in the rail?
With the increase of axle load and the increase of vehicle speed, the rail type of rail becomes more and more heavy, and the performance develops to high strength. In the manufacturing process, from hot rolling to full heat treatment after rolling.
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:The previous track is seamed, there is no gap, is how to achieve
The seamless rail technology in China has been developed independently. The first step is to weld each 25 meter long rail in the welded rail mill into 250 meters long rails, and then use the long rail train to the construction site and weld them into 1 to 2 km long rails. After that, the long rail is connected with a section of a rail, and the rail is firmly buckled on the sleeper by a fastener.
Q:What is the width of the rail grade 43kg/m?
The level of rail 43kg/m, then the cross-section size is 140 mm, the cross-sectional area is 114 square centimeters, theoretical weight is 70 kg.
Q:How to repair welding rail?What kind of electrode is used in rail welding? What's the problem easily?
The rail welding is divided into the docking and repair welding. Rail butt can use aluminium heat welding, with aluminum and iron oxide mixed in proportion, with mold fixed rail, fill the thermite at the seams, lit by magnesium. Because the operation is complex, the heat affected zone, is now rarely used now commonly used. Use special welder. But after welding to reduce the total length of a point.
Q:The hardness of the crane wheel is larger than that of the rail
If the ratio of hardness words, to look at how you play with, good driving wheel with common rail, if the track rail gnawing words, but for sure the grinding wheel, if you are high quality configuration, there should be said that, after the rail gnawing internecine. If you do not gnaw rail, the ordinary will be enough for you to use for several years.
Q:60 detailed dimensions of rail
The standard length of China's rail is 12.5m and 25.0m two kinds. Severe, heavy rail using standard length rail 25.0m, other types of track can be used 12.5m25.0m standard length rail.
Q:What is the rail temperature stress?
The rail temperature stress is that the rail will expand and contract when the temperature changes. It is bound by the fastener and the internal force.
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.
