Inside the Great Wall Cast Steel manufacturing workshop, a 69-ton cast steel upper hammer body for a counter-hammer was packaged, loaded onto a truck, and officially shipped to India. This is another example of Great Wall Cast Steel's continuous supply of large structural components to overseas forging equipment manufacturers in recent years, marking that the company's manufacturing capabilities in the field of large forging equipment cast steel parts have gained international market recognition.

　　The counter-hammer is a core forging equipment in the forging industry, utilizing the immense impact force generated by the high-speed collision of upper and lower hammers to form metal billets. As a key moving component of the counter-hammer, the upper hammer body withstands repeated high-frequency impact loads during operation, placing extremely stringent requirements on the fatigue resistance, internal density, and overall structural strength of the cast steel parts.

　　Great Wall Casting Steel's Casting Advantages – How Did It Secure a 69-Ton Export Order?

　　The successful export of this 69-ton core cast steel component of the forging equipment to India relies on Great Wall Casting Steel's years of accumulated technical expertise and manufacturing strength in the field of large cast steel parts:

　　1. Large-Ton Casting Capacity: Great Wall Casting Steel possesses a casting capacity of hundreds of tons of cast steel parts, equipped with large-tonnage electric arc furnaces/refining furnaces and large sand box molding lines, capable of completing the casting of 350-ton-class large cast steel parts in a single operation, with ample molten steel and precisely controllable pouring temperature.

　　2. Casting Process Design Strength: The upper hammer body of the counter-hammer exhibits significant differences in wall thickness and complex heat distribution. Great Wall Cast Steel's process team optimizes riser layout and gating system design through solidification simulation analysis, ensuring the castings have a dense internal structure free of shrinkage cavities, meeting service life requirements under high-pressure impact conditions.

　　3. Heat Treatment and Performance Assurance: Post-casting heat treatment is a crucial factor determining the final performance of large cast steel parts. Great Wall Cast Steel possesses a large heat treatment furnace complex, capable of customizing normalizing, quenching and tempering processes according to product operating conditions, ensuring the castings' mechanical properties (tensile strength, yield strength, impact toughness) fully meet standards.

　　4. Machining and Testing Capabilities: The company is equipped with heavy-duty CNC machining equipment, providing roughing and finishing services for large castings. Furthermore, castings undergo non-destructive testing such as UT ultrasonic testing and MT magnetic particle testing before leaving the factory, with test records delivered to the customer along with the product.

　　5. Export Packaging and Logistics Experience: As seen in the on-site photos, the products are fully sealed in heavy-duty wooden crates, with complete and standardized product information and export markings clearly labeled on the outside of the crates. Great Wall Casting Steel has mature experience in export casting packaging and transportation management, which can ensure that large cast steel parts arrive safely at overseas customers' sites.
