Find here details of Heavy Steel Rail on our website. Today we would like to talk about material analysis of rail press plate.
The track plate is a type of plate used on the rails. The main material is cast steel. In fact, for cast steel, there are different materials to choose from. The rail pressure plate mainly plays a certain connection role to the rail. When the train is running on the rail, it will have a large impact. If there is no component to fix the rail, the rail will be deformed after the impact, or the train will derail. The existence of the track plate is very necessary, let's analyze the material used for the track plate.
Cast carbon steel: cast steel with carbon as the main alloying element and containing a small amount of other elements. Less than 0.2% carbon is cast low carbon steel, carbon content 0.2% to 0.5% is cast medium carbon steel, and carbon content greater than 0.5% is cast high carbon steel. As the carbon content increases, the strength of the cast carbon steel increases and the hardness increases. Cast carbon steel has high strength, plasticity and toughness, low cost, and is used in heavy machinery to manufacture parts with heavy loads, such as rolling mill stands, hydraulic press bases, etc.; Parts that are subject to impact, such as bolors, side frames, wheels and couplers.
Cast low alloy steel: as a 12m Heavy Steel Rail Exporter, we know that cast steel containing alloying elements such as manganese, chromium and copper. The total amount of alloying elements is generally less than 5%, which has a large impact toughness and can obtain better mechanical properties by heat treatment. Cast low alloy steel has better performance than carbon steel, which can reduce the quality of parts and improve the service life.
Casting special steel: Alloy cast steel refining to meet special needs, a wide variety, usually contains one or more high-alloy elements to achieve a special performance. Various stainless steels with chromium or chrome-nickel as the main alloying elements for parts that are exposed to corrosion or high temperatures above 650 °C, such as chemical valve bodies, pumps, vessels or turbine casings for large-capacity power plants.
In fact, for different tracks, the material used for the rail press plates is different. Some manufacturers use insulated track press plates to reduce the radiation of the rails. This also reduces the corrosion of the cast iron plate rails in the surrounding environment, and can better play the track. The performance advantage of the pressure plate.
