How to ensure the high strength and wear resistance of the castings in the production process of Rail Transit Casting?

Ensuring high strength and wear resistance of the castings is crucial in the production of Rail Transit Casting. We carefully select high-quality raw materials, such as high-strength alloy steel, wear-resistant cast iron, etc. These materials themselves have good mechanical properties and wear resistance foundation. Next, we will use advanced melting technology and equipment to strictly control the melting temperature and chemical composition, ensuring the purity and uniformity of the melt.
In the casting process, we use precise mold design and manufacturing techniques to ensure the accuracy of the shape and size of the castings. At the same time, by optimizing the pouring system and cooling system, the solidification rate and temperature gradient of the casting are controlled to reduce internal defects and improve tissue density. In addition, we will also perform heat treatment on the castings, such as quenching, tempering, etc., to further improve their mechanical properties and wear resistance.
In addition to the above process measures, we also pay attention to the post-treatment process of castings, such as shot blasting cleaning, surface strengthening treatment, etc., to improve the surface quality and wear resistance of castings. Through these comprehensive measures, we can effectively ensure the high strength and wear resistance of Rail Transit Casting, meeting the long-term, high load operation needs of the rail transit system.
