ABOUT THIS PROJECT — φ8221 Large Gear for Metso

The φ8221 large gear is a custom heavy steel casting made of ZG45CrMo material, designed and produced by Hanhai Metallurgy for Metso. The gear blank weighs nearly 80 tons and requires UT and MT first-class flaw detection.
This cooperation came after Metso’s on-site inspection at Hanhai Metallurgy, during which the company recognized our technical strength, production capacity, and management efficiency.

PROJECT OVERVIEW — Process Simulation and Precision Casting

After the contract was signed, the technical department of Hanhai Metallurgy conducted repeated digital simulations of the casting process.
Our engineers, production supervisors, and quality control team collaboratively reviewed every stage of the process, conducted risk pre-assessment, and developed a safe and scientific production plan.
From molding to pouring, the operation was completed seamlessly in one process, ensuring structural integrity and dimensional accuracy.

CONCLUSION — Setting a New Benchmark in Northern Henan

The φ8221 large gear represents the largest mill gear ever produced in northern Henan, with quality standards exceeding national specifications.
This successful collaboration officially marked Hanhai Metallurgy as a qualified supplier for Metso, reinforcing our brand as a trusted large cast steel manufacturer in China.

Client Review
