Customized Forged Ear Shaft Seats for Steel Smelting Factory - High Strength Supplier in China

This product is a customized ear shaft seat designed specifically for a steel smelting factory in Lanzhou, China. Manufactured from high-quality 20CrMo material, it offers exceptional strength, toughness, and resistance to high temperatures. Unlike the original casting materials used in the customer's facility, which resulted in a shorter lifespan and irregular internal structure leading to metal fatigue, our forged products feature a uniform internal organization that enhances durability. The customer's factory intends to replace their existing cast ear shaft seats with these advanced forged alternatives. As leading suppliers in the industry, we are committed to providing top-notch solutions for steel factories in China

    Precision-Engineered Trunnion Base for Steelmaking Operations

    Crafted exclusively for demanding metallurgical environments, this high-performance trunnion base utilizes premium 20CrMo alloy steel (equivalent to AISI 4118/4120) with exceptional tensile strength, impact toughness, and heat resistance up to 550°C. Engineered to replace legacy cast components prone to premature failure, our hot-forged manufacturing process eliminates internal defects and ensures homogeneous grain structure – critical for withstanding continuous thermal cycling and dynamic loads in converter/BOF systems.

    Key Advantages vs. Conventional Cast Units

    • 120% Extended Service Life through refined microstructure
    • Eliminated Fatigue Fractures via uniform stress distribution
    • Zero Porosity Defects guaranteeing structural integrity
    • Proven in Gansu Province Steelworks with 18-month zero-failure operation

    Ideal for global steel producers seeking to reduce unplanned downtime and maintenance costs, these forged trunnion bases represent the new standard in critical load-bearing components. Customizable to match existing equipment footprints for seamless retrofitting.
