Applications of Hot Rolled Light Steel Rail for Warehouse ,Minas, Structures

Light rail is mainly used in forest region, mines, factories and construction sites laid of the place such as temporary transport line and light motorcycles with line.

Heavy 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.

Packaging & Delivery of Hot Rolled Light Steel Rail for Warehouse ,Minas, Structures

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

High Quality Steel 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:Why is rail insulated?
The rail must provide a continuous, smooth, and least resistant rolling surface for the wheel. In electrified railway or automatic block section, rail can also be used as track circuit.
Q:What is a rail flaw detector used to detect?
The main defects in the rail are nuclear damage (white nucleus, black nucleus), crack and so on. If these defects are not found in time, they will expand and cause accidents. Special attention should be paid to the cracks in the holes at the rail joints and the transverse cracks in the rails, because these defects will easily lead to fracture of the rails. Bar and square steel, resulting in defects and inclusions, shrinkage, crack etc..
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:What is quenched rail?
. In the past, the heat treatment of the rail head was made by high frequency induction heating or flame heating to 850~900 degree Celsius, and then quenched at 600~650 C for tempering at high temperature to obtain the structure of tempered bainite.
Q:What is the function of a railway joint connection part?
The joint connection parts include plywood, bolts and spring washers. Plywood. Commonly known as fish plate, with the same steel rail made of material. The utility model is mostly double headed, and the upper and the lower sides are inclined planes and are wedged with the bottom surface of the rail head and the top surface of the bottom. Bolts. A fastener that clamps a rail with the pressure of a nut against a splint. In order to prevent the nut from tightening and loosening due to the vibration of the train, a spring washer is required. Bolts are usually made of high carbon steel and should not be too large in diameter to avoid excessive damage to the strength of rails and cleats. Some countries also add a nylon sleeve around the bolts to reduce vibration and prevent the loosening of the nut. Rail joint is the weak link of track. In order to reduce rail joint, the standard length rail can be welded into long rail of certain length.
Q:55Q rail performance
This is the main rail material of different carbon content, the other is brittle and ductile tensile strength and impact strength are not the same, 55Q rail material is mainly used for mine rail, and Q235 is more commonly used, but cheaper
Q:Does the crane use the touch wire or the rail directly?
The sliding rail line (fixed part, and is connected to a power supply rail, often by a single 4m/ or 6 meters long root / root connected together), the collector (or within the sliding part, can slide wire track and sliding contact with the copper strip to take power, for the collector is connected with the mobile motor).
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 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.
Q:Generally, how often do rail rails change?
This depends on the line conditions, such as the Daqin Line Heavy Haul lines, because each year the volume can reach 7 tons, generally less than a year to track, on the small radius curve rail replacement cycle is shorter, for many reasons, such as serious abrasion, stripping off block etc..
