University-Industry Strategic Partnership

Qingzhou Taihong & University of Science and Technology Beijing (USTB)

In September 2025, Qingzhou Taihong Wear-Resistant Materials Co., Ltd. officially partnered with the University of Science and Technology Beijing (USTB)—a premier national authority in metallurgy and materials science—to launch a landmark RMB 102 Million ($14M+) high-performance wear-resistant materials development project.

Combining USTB's authoritative metallurgical research facilities with Taihong's 11 proprietary manufacturing equipment patents, this joint innovation focuses on optimizing high-chrome alloy formulas, upgrading automated heat-treatment processes, and elevating product standards to deliver ultra-durable, cost-effective grinding media for world-class mining, cement, and power plant operations.

Advanced Testing & Strict Quality Control

Equipped with state-of-the-art laboratory testing instruments to ensure high hardness, exceptional wear resistance, and ultra-low breakage rates for every batch of grinding balls.

  • ✓
    Chemical Composition Precision (Spectrographs)

    Using advanced direct-reading spectrographs and wet chemical analyzers, we rigorously inspect raw material heat codes and alloy ratios (Chromium, Carbon, Manganese) to guarantee exact chemical specifications.

  • ✓
    Hardness & Impact Toughness Assurance

    Fully automatic Rockwell hardness testers inspect surface-to-core hardness gradients, while impact toughness detectors ensure high energy absorption to prevent ball breakage under heavy mill impacts.

  • ✓
    Metallographic Structure & Internal Quality

    High-precision metalloscopes and wire cut preparation equipment allow detailed grain structure analysis and defect-free internal inspection, providing full quality traceability from raw steel to finished products.
