Heavy Type Railway GB Standard Steel Rail Railway Equipment Heavy Rail 43kg Steel Rail Railroad
The development of steel rails can be traced back to the early 19th century. Prior to the use of steel, railways were constructed using cast iron rails. However, these rails were prone to cracking and breaking under heavy loads, limiting the efficiency and safety of railway transportation.
The introduction of steel rails revolutionized railway transportation. Steel rails were able to withstand heavier loads and higher speeds, leading to increased efficiency and capacity in railway systems. With the durability of steel rails, maintenance costs and downtime were greatly reduced, allowing for more reliable and continuous train operations.
Since the introduction of steel rail, there have been ongoing advancements in steel production techniques and rail design. Steel alloys with specific properties, such as high wear resistance and corrosion resistance, have been developed to meet the demands of modern rail transportation.

ADVANTAGE
Rail testing is a test method used to test the quality, performance and condition of rail. Rail testing mainly includes the following aspects:
Appearance inspection: Check whether there are cracks, folds, inclusions, pores and other defects on the rail surface, and whether there are segregation, decarbonization, hard points and other defects at the end of the rail.
Physical and chemical test: Through metallographic analysis, hardness testing, chemical analysis and other test methods, to detect the microstructure and chemical composition of the rail, so as to judge its internal quality.
Flaw detection: The use of ultrasonic, magnetic powder, eddy current and other detection methods, the comprehensive or local inspection of the rail, to find and determine the surface and near-surface defects.
Dynamic detection: The loading and vibration test of the rail is carried out by simulating vehicle driving, and the performance indicators such as the bending performance and impact absorption energy of the rail are detected.
Environmental adaptability test: Simulate the use environment under different environmental conditions, such as high temperature, low temperature, corrosive gas, etc., to test and evaluate the performance of the rail.
Through these test methods, the quality, performance and state of the rail can be effectively tested to ensure its safety and reliability in railway transportation.

APPLICATION
There are heavy rails, light rails, and lifting rails in the rails. The difference between heavy rail and light rail is that the weight per unit length of the rail is different. Rails weighing more than 30kg per meter are called heavy rails; rails weighing less than 30kg per meter are called light rails. Generally, heavy rails are mainly used on railway tracks, and hoisting rails are mainly used in lifting cuttings.
The light rail is mainly used for laying temporary transportation lines and light locomotive lines in forest areas, mining areas, factories and construction sites. Material: 55Q/Q235B, executive standard: GB11264-89.
PACKAGING AND SHIPPING
First, countries have followed such a principle in the design of the rail head tread: the arc of the rail top tread conforms to the size of the wheel tread as much as possible, that is, the size of the tread arc, such as the 59.9kg/m rail in the United States, the rail head arc is adopted R254-R31.75-R9.52; the 65kg/m rail of the former Soviet Union, the rail head arc adopts R300-R80-R15; the UIC 60kg/m rail, the rail head arc adopts R300-R80-R13. It can be seen from the above that the main feature of the section design of the modern rail head is the use of complex curves and three radii. On the side of the rail head, a straight line with a narrow top and a wide bottom is adopted, and the slope of the straight line is generally 1:20~1:40. A straight line with a large slope is often used at the lower jaw of the rail head, and the slope is generally 1:3 to 1:4.
Second, in the transition zone between the rail head and the rail waist, in order to reduce the cracks caused by stress concentration and increase the frictional resistance between the fishplate and the rail, a complex curve is also used in the transition area between the rail head and the rail waist, and a large radius design is adopted in the waist. For example, UIC's 60kg/m rail uses R7-R35-R120 in the transition zone between the rail head and the waist. Japan's 60kg/m rail uses R19-R19-R500 in the transition zone between the rail head and the waist.
