Baiyin Metallurgy Drive Alloy Steel Forging Case, Gansu

Jianing Forging presents a comprehensive case study on the supply of alloy steel forged components for the Baiyin Metallurgy Drive project in Gansu. This case demonstrates how our precise forging solutions addressed critical operational challenges in heavy industrial drive systems.

Case Overview

In this project, a prominent metallurgy enterprise required high-strength alloy steel drive shafts and gears for a large-scale rolling mill upgrade. The components needed to withstand extreme torque fluctuations and high-temperature operating environments while maintaining dimensional accuracy over extended service cycles.

Customer Pain Points

The client faced three major challenges: frequent premature fatigue failures in existing forged parts due to inadequate material homogeneity, high rejection rates caused by inconsistent grain flow patterns in complex geometries, and extended downtime during maintenance due to non-standard replacement part dimensions. These issues led to reduced production efficiency and increased operational costs.

Our Solution & Product Advantages

To address these pain points, Jianing Forging developed a tailored alloy steel forging process employing controlled thermomechanical treatment. Our approach included:
- Utilization of vacuum-degassed, microalloyed steel grades to enhance internal cleanliness and fatigue resistance.
- Multi-directional forging sequences combined with optimized reduction ratios to achieve uniform grain refinement and isotropic mechanical properties.
- Precision CNC machining of critical surfaces with tolerances within ±0.02mm, ensuring seamless interchangeability with existing drive system components.
- Rigorous non-destructive testing (ultrasonic and magnetic particle inspection) for every forged piece, guaranteeing defect-free material integrity.

The delivered forged shafts and gears demonstrated a 40% improvement in fatigue life compared to the client's previous supplier, with zero dimensional deviations across the first batch of 50 units. Field performance over 18 months showed no maintenance-related stoppages attributable to the forged components.
