Casting Rail Shoulders

Casting rail shoulder is a rail shoulder produced by casting method, which is usually used in railway, subway, light rail and other track systems. Casting is a method of pouring liquid metal into a casting cavity that matches the shape of the part, and after it cools and solidifies, the part or blank is obtained.
Cast rail shoulders are made by pouring molten iron into a mold through a casting process to make castings that match the shape of the rail shoulders. After cooling and processing, they can be used in the track system. Cast rail shoulders have high strength and wear resistance, and can withstand large pressure and impact forces, so they are widely used in track systems. At the same time, cast rail shoulders also have good durability and stability and can be used for a long time in different environments and climate conditions.

Sand casting: This method uses a sand mold for casting. The molten metal is poured into the sand mold, and after it cools and solidifies, the cast rail shoulder can be obtained. The advantages of sand casting are lower cost and short production cycle, but the disadvantages are lower precision and poor surface quality. 

Precision casting: Precision casting is a method of producing high-precision, high-quality cast rail shoulders through precision casting processes and molds. The molds used in this method are usually metal molds or high-precision plastic molds, which can achieve higher accuracy and surface quality.
Centrifugal Casting: Centrifugal casting is a method that uses a centrifugal force field to produce cast rail shoulders. The molten metal is poured into the rotating mold, and the centrifugal force field causes the metal to form a thin shell on the inner wall of the mold. After it cools and solidifies, the cast rail shoulder can be obtained. The advantages of centrifugal casting are high production efficiency and low cost, but the disadvantage is that it is only suitable for the production of cylindrical or tubular cast rail shoulders.
In short, casting rail shoulder is an important track component, and its quality and performance are of great significance to ensure the safe operation of trains. There are many production methods for cast rail shoulders, and different methods are suitable for different production needs and product requirements. Choosing the appropriate production method is of great significance to ensure the quality and performance of cast rail shoulders.
