Heavy Rail  wavy wear refers to the wavy uneven wear on the top surface of the rail, which is essentially wavy crushing. Wave grinding will cause high wheel and rail power effects, accelerate the damage of locomotive vehicles and track components, and increase maintenance and repair costs. In addition, the severe vibration of the train will make passengers uncomfortable and will also threaten driving safety in severe cases. origin of. There have been serious waves in some of our country's freight routes. Its development speed is faster than side grinding, and it has become the main reason for changing rails. Heavy Rail Wave grinding can be divided into two types: short wave (or wave) and long wave (or wave). The ripple is a periodic irregularity with a wavelength of about 50-100mm and an amplitude of 0.1-0.4mm; the long wave is a periodic irregularity with a wavelength of more than 100mm and less than 3000mm and an amplitude of less than 2mm. Wave grinding mainly o...

Heavy rail I-beams, also called steel beams, are long steel bars with I-shaped cross sections. The specifications of I-beam can be expressed by the model. The model represents the number of centimeters of waist height. The I-beam with the same waist height has several different leg widths and waist thicknesses. It is necessary to add abc to the right of the model to distinguish. Steel and light I-beam, high-quality profiles are profiles made of high-quality steel. It is divided into hot-rolled (forged) high-quality profiles, cold-drawn (drawn) high-quality profiles and other varieties. Hot rolled (forged) high-quality profiles include carbon structural steel, carbon tool steel, alloy structural steel, spring steel, stainless steel, bearing steel, alloy tool steel, die steel, high-speed tool steel and other varieties. Cold-drawn (dial) high-quality profiles include carbon structural steel, carbon tool steel, alloy structural steel, spring steel, stainless steel, bearing steel, alloy to...

Heavy Steal Rail  is a heavy rail, which is different from light rail. It is a track run by heavy vehicles. It is not the weight of the track itself. The requirements are relatively high. Because heavy-duty vehicles run on heavy rails, the rails are heavier and the specifications of the rails are higher. The heavy rail has a larger cross section than the light rail and can withstand greater forces. Cracks on the surface of the rail: including screw hole cracks, rail head jaw cracks (through embroidery), rail waist horizontal cracks, rail head longitudinal cracks, rail bottom cracks, etc. (excluding the top or near surface of the rail caused by wheel-rail contact fatigue is fish scale crack). The length of the chin of the rail head is more than 30mm. The rail was deformed in any part (the rail head was enlarged, the rail waist was twisted or bulging), and it was confirmed that there was a dark crack inside. Heavy Steal Rail In order to facilitate the statistical ana...

As an infinitely long beam supported on a continuous elastic foundation, the rail mainly bears concentrated vertical loads from rolling stock and generates a certain bending moment on its section. Rails are rarely damaged due to insufficient cross-section bending strength. What are the main reasons for rail replacement?  Steel Crane Rail Manufacturer  will tell you next. The main reasons for rail replacement are wear and fatigue. The wear of light steel rails manifests in different forms and degrees on straight lines and curves. The saddle-shaped abrasion of the joint part is mainly on the straight line. The curve is mainly the side wear of the outer strand rail, the head crush and wave wear of the inner strand rail, and it is especially serious on the small radius curve. The main manifestation of rail fatigue damage is nuclear injury. It originates from the small cracks existing inside the rail head. With the extremely complicated stress combination inside the rail head ...

Train rails are used to lay railways. To withstand the stress, impact load and friction of the train operation, it is required to have sufficient strength and certain toughness. The quality requirements are strict. In addition to ensuring its chemical composition, it is also required to test mechanical properties, drop weight test and acid immersion low-fold structure. Light rails are used to lay railways, and they must withstand the pressure, impact load and friction of the train operation, and require sufficient strength and certain toughness. The quality requirements are strict. In addition to ensuring its chemical composition, it is also required to test mechanical properties, drop weight test and acid immersion low-fold structure. The standard length of the rail is 12.5m and 25m. Heavy-duty rail: Rails with a nominal weight of more than 30kg per meter. Train rails and crane rails are heavy rails. Crane rail: the  Steel Crane Rail , its height is low, the head width and waist ...

Heavy rail, that is, heavy-duty track, is different from light rail. It is the orbit of heavy-weight vehicles. It is not the weight of the single-track track itself, but it is also related. Because the track of a heavy-weight vehicle is to bear a large vehicle weight, the rail is relatively heavy and the specification of the track is relatively high. The  43kg Heavy Rail Manufacturer  below will take you to understand the heavy rail. Heavy Rail Track system: The weight of vehicles is divided into light rail and heavy rail. The track width is divided into wide rail, standard rail, narrow rail (including meter rail and inch rail), and the application range of heavy rail is mainly national standard inter-regional railway (including high-speed railway, heavy-duty railway), inter-city railway, city area. Railways, as well as subways in urban rail transit, are all heavy railroads. Rail weight rail specifications are expressed in net kilograms per meter length.  Ste...
