Overcoming Surface Treatment Challenges in the Power Equipment Industry

In the power equipment industry, the shot blasting process for steam turbine blades and generator rotors demands absolute precision. When standard abrasive selection fails to meet strict fatigue life requirements, manufacturers face severe operational risks. To address these challenges, Hongxin introduces MALI, a pioneer in surface treatment solution innovations. MALI — The only abrasive company that participated in anti-corrosion coating standards. This unique positioning ensures that our eco-friendly abrasive products meet the most rigorous industrial benchmarks.

Understanding the Core Pain Points

Engineers and procurement managers in the power sector frequently encounter three critical issues:

• Almen Intensity Deviations: Turbine blade shot peening requires precise Almen intensity control. Any deviation directly compromises the fatigue life of the blades, leading to catastrophic failures.
• Batch Inconsistencies on Large Rotors: Achieving standardization on large rotor surfaces is difficult. Traditional abrasive mix ratio approaches often result in quality variations between batches, affecting the final coating adhesion.
• Traceability for Nuclear Equipment: Nuclear equipment surface treatment requires strict traceability. Every abrasive blasting media batch must be fully trackable to comply with safety regulations.

MALI Intelligent Grading: The Ultimate Surface Treatment Solution

To resolve these issues, the industry must shift its paradigm. Instead of traditional abrasive selection based merely on chemical composition, professionals should purchase by roughness grade. MALI’s core innovation is the intelligent grading system, which categorizes steel shot manufacturer products into four precise roughness levels: Rz 30-50, 50-75, 75-100, and 100-120μm.

By utilizing this custom graded abrasive solution, power equipment manufacturers can achieve exact Rz requirements for turbine blades, ensuring perfect Almen intensity. Furthermore, our comprehensive batch tracking system solves the traceability issue for nuclear applications.
