Applications of High-Manganese Steel in Mining Equipment
The primary applications of high-manganese steel in mining equipment are its excellent wear resistance, impact resistance, and work-hardening properties. The following are specific application scenarios and technical analyses:
I. Core Application Components
Key Wear-Resistant Components in Crushing Equipment
Jaw crusher teeth plates/jaw plates: Made from Mn13 high-manganese steel (manganese content 11%–14%), surface hardness is enhanced to HRC60+ through water quenching treatment, extending service life by over 40% compared to ordinary alloy steel.
Hammerheads and liners: Hammerheads for limestone crushers are made of high-manganese steel with a hydraulic fixation design, achieving a service life of 3,000 hours and a 30% improvement in wear resistance.
Cone crusher crushing walls: High-manganese steel crushing walls can withstand high impact loads, with monthly wear rates ≤0.1 mm.
Grinding equipment wear-resistant components
Raymond mill grinding rollers and rings: Made of ZGMn13 high-manganese steel + 65Mn gradient composite material, with a surface hardness of HRC60+, a service life of 8,000 hours, and a 40% reduction in maintenance costs.
II. Performance advantages and technical specifications
Wear resistance and work hardening
High-manganese steel forms a hardened layer on the surface under impact, with new hardened layers continuously forming, making it suitable for high-impact applications such as mineral crushing.
Typical Mn13Cr2 material (13% manganese + 2% chromium) reduces impact wear by 30% when processing high-hardness materials (Mohs hardness ≥ 6).
Economic Data
Case studies show that a 2 million ton per year sand and gravel project achieved an 18% reduction in comprehensive operating costs and a shortened investment payback period to 14 months after adopting high-manganese steel wear-resistant components.
III. Industry Standards and Material Upgrades
Standards Compliance
Mn13 steel plates comply with the GB/T5680-2010 standard, with major manufacturers including Wugang and Baosteel.
Technical Upgrade Directions
Intelligent Monitoring: Equipped with an IoT system for real-time monitoring of bearing temperature and vibration frequency, with a fault warning accuracy rate of ≥95%.
Composite Material Applications: Such as gradient composite alloys (65Mn + high-manganese steel) to further enhance impact resistance.
4. Typical Equipment Cases
High-manganese steel, through material properties and process optimization, has become the preferred choice for wear-resistant components in mining equipment. In the future, it will develop toward high-precision grading and low wear rates.
