Do you know what problems are likely to occur during the use of rails? Rails are prone to problems during use, and these problems are manifested in eight forms. The  Steel Crane Rail Manufacturer  will give you a detailed introduction below. 1. Seamless line welding low collapse and empty hanging. The weld seam and heat-affected zone wear and collapse of the welded joints are fast, and the saddle-shaped abrasion irregularities appear during operation, which increases the additional power of welding, which is the main reason for the welding to collapse and empty; Track bed compaction, slip and subsidence, muddling and mud fallout, sleeper failure, etc., have accelerated welding low collapse and empty hanging. 2. Seamless line aluminum thermal welding head arch back. The main reason is that the welding process is incomplete, resulting in permanent deformation of the geometry of the welding place, resulting in the phenomenon of welding arch back. 3. The track bed is ...

It is generally believed that the shear stress under the rail surface caused by the contact stress is the main reason for the rail damage caused by the vertical force. Due to the interaction of wheels and rails, the contact stress on the top surface of the rails repeatedly causes plastic deformation, fatigue wear and fatigue cracks on the rail surface. The  Steel Crane Rail Manufacturer will introduce the damage to the rail surface. 1 Rail head plastic deformation and wear Rail plastic deformation is directly proportional to contact stress and inversely proportional to rail hardness. When the contact stress is close to the shear yield limit of the rail, the contact surface begins to plastically deform. When the contact stress reaches 4 times the shear yield limit, continuous accumulated plastic deformation occurs on the contact surface, which causes the rail head to be widened or rolled. At the same time, the rail top surface metal is hardened, the hardness is increased, and...

Generally speaking, the heavier the  Steel Rail , the less damaged the rail will be, and it will not be easy to bend and deform. According to this problem, there are two ways of strengthening. 1. Rail alloying. It has simple production process, low investment, low energy consumption, overall strengthening of the rail, uniform surface hardness, and good weldability. 2. Heat treatment of carbon steel, this method can also improve the strength and hardness of the rail, at the same time good toughness, saving alloy, suitable for mass production. The metallurgical industry production practice believes that if the steel type is not changed, it is difficult to greatly increase the strength only by heat treatment of carbon steel. Only by combining microalloy and heat treatment, the two can complement each other to obtain the higher strength, and high quality steel rails with corresponding toughness, hardness and weldability. These two methods can greatly reduce the previous situ...

We know that the rail is mainly used in some steel rail roads or some special vehicle guide rails. Its use is very important to us. Let's look at the rail knowledge explained by  Steel Crane Rail Manufacturer . Crane Rails Rails with a nominal weight of more than 30kg per meter. Both train rails and  Crane Rails  are heavy rails. Train rails: used for railway laying, to withstand the pressure, impact load and friction during train operation, sufficient strength and certain toughness are required. The quality requirements are strict. In addition to ensuring its chemical composition, it also requires inspection of mechanical properties, drop weight test and acid leaching low-power structure. Crane rail: The crane rail has a low height, a large head width and a large waist thickness, and only requires inspection of chemical composition and tensile strength. Used for laying crane tracks and trolley tracks. It is a steel rail with a nominal weight of less than or ...

Light Steel Rail  as a whole engineering structure, the track is laid on the subgrade, plays a guiding role in train operation, and directly bears the huge pressure of rolling stock and its load. Under the power of train operation, its various components must have sufficient strength and stability to ensure that the train runs safely, smoothly and uninterrupted at the maximum speed specified. Light Steel Rail 1. Rails Railway equipment is an important railway equipment, and steel rail is the main symbol of railway equipment. Classification Steel rails can be divided into heavy rails and light rails in terms of kilograms of approximate weight per meter: ① Heavy Steel Rail . According to the type of steel used, it is divided into: ordinary manganese-containing rails, copper-containing ordinary carbon steel rails, high-silicon copper-containing steel rails, copper rails, manganese rails, and silicon rails. There are mainly three types of 38, 43 and 50kg. In addition,...

There are many types of  railway track fasteners , which are roughly divided into three categories of accessories, each of which has its own special existence. The first is the  railway track  connection fittings, one is the connecting fittings of the same side rails, and the other is the connecting fittings between the parallel rails. Commonly used connecting components between parallel rails are gauge rods, gauge feet, and other link accessories. The general gauge pull rod is a common rail connection accessory in railway fittings. In special cases, an insulated gauge rod is required. The splint is an indispensable accessory in the railway track connection and is used for the connection between the rail and the rail. The second is the railway track products, one is the  GB standard steel rail , and the other is the large-sized ballasts and cores in the railway track. The laying of railway rails in railway transportation is the basic configuration and appears in...
