Bi-metallic Casting | Nanhai Machinery

1. Why Bi-metallic Casting is a Great Way to Achieve Toughness and Wear Resistance? There has been a massive demand for casting with special characteristics such as corrosion and wear resistance. Bi-metallic castings are a great way to avoid cracks in the heated zone and making an additional layer using a welding method. These are mainly comprised of alloy steel with a chrome white iron, known for toughness and easy wear out. Ever wondered about combining chrome white iron with bi-metallic castings? CWI and steel are united together to form an exceptional way to achieve wear resistance and toughness. CWI on bi-metallic liners reaches 60 HRC in hardness while steel remains in a good condition in terms of strength and durability. Why bi-metallic liners are used? Bi-metallic castings are designed with two or more metal components, which results in resistance to corrosion, and abrasion, or both. Because of their outstanding resistance to impact as well as wear, they are commonly used in chutes, hoppers, mix boxes, and more. You may witness these castings on places like mine and oil fields at the bottom of hoppers and mix boxes to gently absorb the impact pressure that other kinds of bimetal plates couldn’t manage. How do bi-metal castings work?

2. This advanced technology integrates various casting materials into a single product. Several melts are discharged one after the other into multiple mould sections and further solidified together. The method takes place in complete requirements to ensure different materials and sections of the same casting without any compromise to quality and performance. This technique is good to combine with crusher liners to achieve a high level of wear-resistant alloy. It can be used to alter weldable areas of white cast iron elements, so they can be collected fast and seamlessly. Optimal automation and production techniques result in an economical high-grade solution for series parts to meet complex challenges and industry requirements. Key Benefits Bi-metallic casting provides a wide range of benefits in comparison to single-alloy casting, which includes: •Combine the exceptional properties of two different metals •Ideal production of high-wear resistant shells with tough inner cores •Enhance both breakages and wear resistance Bi-metal castings usually start with a controlled melting and metal alloying. Unique casting procedures allow you to achieve a rapid rate of heat transfer, right from the shell to the core portion to deliver a solidified metal. It produces components that are high wear-resistant and have tough inner cores.
