product key technologies
The core advantage of the High Manganese Steel Wear Resistant Liner Board lies in its unique work hardening performance. When subjected to strong impact and friction during use, the surface of the liner board will quickly form a hardening layer (hardness up to HRC 55-60), while the inner core still maintains good toughness, which effectively avoids the problems of brittle fracture and falling off that are common in ordinary wear-resistant liner boards. This special performance makes the High Manganese Steel Wear Resistant Liner Board especially suitable for working environments with high impact and high wear, and its wear resistance is 5-8 times that of ordinary carbon steel liner boards.
Our High Manganese Steel Wear Resistant Liner Board is manufactured in strict accordance with national and international industry standards, with precise size control and smooth surface. The product adopts integral casting or welding structure design, which has strong structural stability and can be closely attached to the inner wall of the equipment, effectively reducing the impact of materials on the equipment shell, extending the service life of the main equipment, and reducing maintenance costs and production downtime. At the same time, we can adjust the material formula and product structure according to the specific working conditions of customers, so as to meet the personalized needs of different industries.

Excellent Product Features, Laying a Solid Foundation for Wear Resistance
Exceptional wear resistance and durability:
Crafted from high-strength high manganese steel with a stable structure, it acts as a core wear-resistant component in grinding processes and effectively prolongs the equipment operation cycle.
Safe and compliant material:
Produced via medium frequency electric furnace smelting combined with metal mold or sand casting technology, it strictly follows national safety standards to control material purity and stability from the production source.
Excellent fracture resistance:
A small amount of rare earth elements are added to the material, which greatly enhances its grinding and crushing resistance, prevents breakage and excessive wear, and adapts to complex and harsh working environments.
Strong compatibility:
It can be flexibly adapted to the working conditions of different industries, meeting the installation and application requirements of various types of equipment.
Diverse Application Scenarios, Covering Industry-wide Needs
High Manganese Steel Wear Resistant Liner Board has an extremely wide range of applications, covering core industrial fields such as metallurgical mines, cement building materials, thermal power generation, flue gas desulfurization, aerated concrete magnetic materials, chemical industry, and coal water slurry. In practical production, it is often used to manufacture wear-resistant components such as excavator bucket teeth, rolling wall and crushing wall of cone crushers, jaw crusher fork plates, ball mill liners, railway switches, plate hammers, and hammerheads. It can easily cope with high-wear and high-impact operating scenarios, providing effective protection for core equipment components and improving overall production efficiency.
Production Process
Raw Material Inspection & Preparation
Select pig iron and scrap iron (1:1-2 ratio) as the matrix, strictly inspect chemical components (C, Mn, Si, etc.) to meet ZGMn13 series or customized standards, and prepare refining agents to reduce casting defects.
Smelting & Refining
Melt pig iron, conduct desulfurization and deoxidation, add alloy elements in batches (23-26 minutes intervals) for alloying, then melt scrap iron for secondary refining and adjust components to qualification.
Casting Molding
Adopt sand-lined metal mold casting, design reasonable gating/feeding systems and insulation risers to reduce defects; metal mold cooling refines grains and improves casting accuracy.
Post-Casting Heat Treatment (Water Toughening Treatment)
Core process: Heat to 500-510℃ (200-220℃/h, 60-70min heat preservation), then to 700-710℃, cool to 560-590℃, reheat to 940-950℃ (3-4h), then water quench to obtain austenite structure.
Machining & Surface Treatment
Precision machining according to drawings; sandblasting/shot blasting to remove oxide scale and burrs, improving surface quality and corrosion resistance.
Factory scene
Common domestic grades & application scope
All grades have a manganese content of 11.0%~14.0%, and the high manganese steel liners of these grades enjoy huge market demand. Specific parameters and applications are as follows:
ZGMn13-1 (C: 1.10%~1.50%): For low-impact components
ZGMn13-2 (C: 1.00%~1.40%): For ordinary components
ZGMn13-3 (C: 0.90%~1.30%): For complex components
ZGMn13-4 (C: 0.90%~1.20%): For high-impact components
