The material of straightening roll (ring) for section steel rolling machine
Straightening rolls, also known as straightening rings, are rolled parts with circular, roller or cylindrical cross sections, and are an important component of section steel rolling machines. Section steel straightening rolls need to withstand severe bending and rolling pressures and must have good structural stability and wear resistance. As a result, the material for producing the straightening rolls for section steel rolling machines must have the necessary characteristics to ensure the quality of the finished product.
The most commonly used materials for section steel straightening rolls are 1045 carbon steel and 42CrMo. 1045 carbon steel has a carbon content of 0.45%, and it encompasses numerous other elements, such as chromium, manganese and molybdenum. When selecting 1045 carbon steel, consideration should be given to the necessary purposes and components, such as strength, toughness and wear resistance, since 1045carbon steel offers advantages in these areas. 42CrMo is an ultra-high strength alloy steel, which offers increased strength and wear resistance while also reducing the weight of the part. Additionally, 42CrMo also has excellent mechanical properties and good machinability, making it suitable for a variety of processing methods.
In addition to 1045 carbon steel and 42CrMo, other materials such as cast iron, stainless steel and titanium can also be used for the straightening rolls for section steel rolling machines. Cast iron is often used due to its excellent castability and machinability, while titanium is often used due to its high strength and good corrosion resistance. Stainless steel, on the other hand, is often used due to its excellent corrosion resistance and wear resistance properties.
Each material has its own advantages and disadvantages, and the selection of the material for the straightening rolls for section steel rolling machines will depend on the application and required characteristics for the part. Taking into consideration the strength and wear properties of the different materials, along with their cost, will ensure the best material is selected for the job. 1045 carbon steel and 42CrMo are the two main materials used for the straightening rolls for section steel rolling machines, but other materials such as cast iron, stainless steel and titanium may also be used depending on the application.
