Along with the development of the technology, we merely use the white cast iron. In a word, the white cast iron is difficult to manufacture. Because it contents much more Fe3c, so the white cast iron has high hardness and high fragility. White cast iron, the carbon content is almost 2.5%. In term of forging the tie plate, we would like to choose white cast iron. Based on these characters, it is always used to casting the tie plates and other rail components.įorging is a common method to manufacture the tie plate. Besides, it has high impact toughness at room temperature. The QT400-18 has better weldability, machinability, and plasticity. Cast iron is mainly composed of iron, carbon and silicon alloy. The QT400-18 is made up of the steel, carbon and silicon. For making the tie plate by casting, we would like to choose the QT400-18 carbon steel. The Q235 carbon steel has a good overall performance so that it is widely used in the railway system.Ĭasting is the most common method to manufacture the railroad tie plate. Because the carbon content is moderate, and the strength, plasticity and welding can fit better. Q refers to the yield limiting, and “235” means the yield value is almost 235Mpa. Q235 carbon steel is also called A3 carbon steel. Generally, for the rolling tie plate, they are made of Q235 carbon steel. As for using the rolling measures, it has the requirements for the raw material.

We have a professional team and the mature technology, so we can guarantee the quality of the tie plate. We will introduce the materials according to the different manufacture methods.Īs a leading manufacturer in China, AGICO Rail firstly adopted rolling technology to make railroad tie plates. For different processing methods, the materials are different. With the development of the technology, AGICO Rail as a railway fasteners manufacturer, we try to manufacture the tie plates by rolling the raw materials. There are many manufacturing methods of the railroad tie plates like casting and forging in the past. For the hook twin tie plate, we have been made A Study for Hook Twin Tie Plate Testing already, so we can guarantee the quality of our products.
Hook twin tie plate is a kind of tie plate which is used for frog and railway switch. Double shoulder tie plates are a commonly used type tie plate nowadays. Nowadays, the single shoulder tie plates are usually used on the outside of the railsĭouble shoulder tie plate has two shoulders on the top surface. Along with the railway system developed, the single shoulder tie plate has been knocked out gradually. Single shoulder tie plate, as its name, there is a shoulder on the top surface. There are three typical types tie plates. In general, the railroad tie plate can divide into three types: single shoulder tie plate, double shoulder tie plate and the hook twin tie plate. Meanwhile, the railroad tie plates load distribution to the ties better. Besides, punched and sheared from the steel sections, the railroad tie plates can provide a proper bevel, and uniform bearing surface for the rails. As an important fastener, the railroad tie plate cooperates with railroad spike to fix the rails on the railroad ties. Many countries used the wooden railroad ties as the infrastructure. As a member of the railway fastening system, the railroad tie plates have a crucial impact.Īt the beginning of the 18 th century, the train system develops slowly. Railroad tie plate is a kind of railway fasteners to holds the rails to a correct gauge. Railroad tie plate, we also called the sole plate or base tie plate.
