Invoicing on theoretical weight or actual weight as customer request

Payment terms: 30% advance payment by T/T, 70% payment against the copy of the B/L; 100% L/C at sight, etc.

Usage & Applications of Steel Heavy Rail GB2585-81 with High Quality:

Heavy Steel Rail is suitable for the laying of main trunk line of the curves and the orbit of the tunnel, can also be used for tower crane and other crane track.

For example: railway, subway, transportation track, express, curve way, tunnel way.

 

Packaging & Delivery of Steel Heavy Rail GB2585-81 with High Quality:

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

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

 

6. Delivery Time: All the Ms Heavy Steel Rail will be transpoted at the port of Tianjin, China within 30 days after receiving the advance payment by T/T or the orginal L/C at sight.

Production flow of Steel Heavy Rail GB2585-81 with High Quality:

Material prepare (billet) —heat up—rough rolling—precision rolling—cooling—packing—storage and transportation

Q:What is the width of the rail grade 43kg/m?
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 welding method of rail butt joint?
In order to adjust the melt temperature and the chemical composition of weld metal and alloy, often adding additives amount in thermites. Thermit welding has the characteristics of simple equipment, convenient operation and no power supply. It is often used in welding of rails, bars and other large section workpieces.
Q:U71Mn what does "U" mean in the rail?
Rail steel (rail, steel) is used for the manufacture of locomotives, cranes and other rail steel for professional use. Most of the rail steel by oxygen open hearth and oxygen converter smelting and rolling by. Rail used in the main wear and long-term repeated load, so the requirements of wear, pressure, fatigue, welding and good toughness.
Q:Why can't the vertical rail bend the rail?
The railway line to solve the rail expansion and contraction method is generally used for fastening the way, is the shrapnel into spring fastener fastener (also called spring bar fastener), rail tightly in the sleepers, forcibly will produce thermal expansion and contraction of the energy to digest, but the existence of such a problem is generated when the thermal expansion and contraction energy is greater than the distance unit of sleeper rail adhesion, makes up the phenomenon of rail, rail sleeper unit length twist.
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: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 is the working principle of a rail profilometer?
Two dimensional scanning sensor ZLDS200 series is a small range, high speed and high precision two-dimensional sensor, with digital, integrated structure. The two-dimensional laser sensor ZLDS200 series with high precision can reach Z per second, 0.1% 1200 axis scanning contour data of high response and high degree of protection IP67, and synchronization characteristics of high performance, and in addition to the standard series of products, can also be customized according to the user's special needs.
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:What railway tracks are also live?
The power supply technology is adopted in many cities abroad and in China, with the advantages of beautiful appearance, no visual obstacles of the electric pole and power supply line, and low maintenance cost. The supply rails are usually equipped with protective covers.
Q:What are the requirements of the two rails on the track?
At that level, the same section of line about two shares of the top surface of the rail height difference; line to line tolerance of 4mm, the other line is 6mm.
