Apllications of Steel Rail
Package and Delivery of High Quality HR 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
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:What is rail thermit welding?
- Thermit welding, thermit, welding, welding method using chemical reaction heat as heat source. When welding, advance the end to be welded two workpiece fixed in the mould, then the aluminum and iron oxide powder mixture (called thermite) is heated in a crucible, the reduction of the exothermic reaction, become liquid metal (iron) and slag (Al2O3), injection mold.
- Q:Cause analysis of manganese stiffness in rail
- The characteristics of manganese steel are unique. If the manganese in 2-3% is added to the steel, the low manganese steel is as brittle as glass and cracked at the same time.
- Q:How do seamless rails solve thermal stress problems?
- Seamless line is not entirely seamless, but this gap is pulled very longOrdinary line every 25 meters, one rail seam, seamless rail with long rail and long rail, almost every 1 kilometers to set a rail seam. This rail joint is used to solve the temperature stress as common rail joints
- Q:How to repair welding rail?What kind of electrode is used in rail welding? What's the problem easily?
- Repair welding is found when pitting corrosion pits local rail surface, affecting the smooth operation of the train, but the rail has not reached the need to replace the degree, can be used in welding repair: first by flame heated to a certain temperature, and then use the welding welding, using heat to control the cooling speed. When reduced to a certain temperature. The grinding wheel along the longitudinal smoothing.
- Q:Several questions about high speed rail and subgrade.
- You said concrete thick plate, should be the track board, that is, the use of ballastless track line, there is gravel laying corresponding to the ballasted track. This has nothing to do with operational safety. Many high-speed rail lines are adopted both at home and abroad, and ballasted tracks are adopted.
- Q:How to deal with old rail rail?
- To be recycled all the way, there is a strategic metal "Mo" in the rail, which can make rail super wear, recycling molybdenum extraction, processing new tracks, molybdenum reserves are very low, and strategic metals
- 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: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:What is the connection mode of the return cable on the rail?
- Current transformer installation should pay attention to several points: one is the two circuit transformer is not allowed to open, to prevent the generation of high voltage induction harm, two is the two circuit grounding point, three is the current level of transformer should be greater than or equal to the maximum current in the main circuit, otherwise will exceed the current table
- Q:What is heavy rail? What is light rail?
- 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).
