Erdenet, located in northern Mongolia's Orkhon Province, is globally recognized as one of the world's most critical mining epicenters. Anchored by the massive Erdenet Mining Corporation (EMC)—one of the largest copper and molybdenum mining and ore-processing complexes in Asia—the regional industrial landscape presents extraordinary mechanical and environmental challenges for heavy machinery components.
The processing of abrasive porphyry copper-molybdenum ore involves primary crushing, SAG mill grinding, flotation, and high-tonnage tailings management. Equipment operates under unrelenting severe abrasion, heavy impact, and continuous mechanical shock loads. Furthermore, Mongolia's extreme continental climate demands that cast steel and iron parts maintain high fracture toughness even when ambient operating temperatures plummet to -40°C to -50°C during winter harsh freezes.
Porphyry copper ore in the Erdenet deposit contains high quartz fractions (Mohs Hardness 7), accelerating abrasive wear on jaw crusher liners, cone crusher mantles, ball mill discharge grates, and slurry pump casings by up to 35% compared to standard copper deposits.
Standard carbon steel and low-grade cast irons undergo a ductile-to-brittle transition (DBTT) at freezing temperatures, resulting in catastrophic brittle fractures under high-impact mining stress. Henan Hanhai Metallurgy Mining International Trade Co., LTD addresses this through advanced chemical ladle refining and specialized cryogenic heat treatment protocols.
We supply high-manganese Hadfield steel (Mn13Cr2, Mn18Cr2, Mn22Cr2), chromium-molybdenum alloy steels, and high-chromium white irons optimized for low-temperature Charpy V-Notch (CVN) impact toughness.
| Alloy Grade | Primary Microstructure | Hardness (HB/HRC) | CVN Impact Toughness (-40°C) | Target Erdenet Application |
|---|---|---|---|---|
| Mn18Cr2 Hadfield Steel | Austenitic (Water Quenched) | 220 - 550 HB (Work Hardened) | > 90 Joules | Primary Jaw Plates, SAG Mill Liners |
| Cr-Mo Low Alloy Steel | Tempered Martensite/Bainite | 340 - 420 HB | > 35 Joules | Crusher Support Sleeves, Girth Gear Rings |
| KmTBCr26 High Cr Iron | Eutectic M7C3 Carbides | 58 - 64 HRC | N/A (High Abrasion) | Slurry Impellers, Dredge Pump Liners |
| ZG280-520 Cast Steel | Normalized Ferrite-Pearlite | 160 - 210 HB | > 27 Joules | Hydraulic Press Frames, Sprocket Seats |
To eliminate interior shrinkage cavities, porosity, and non-metallic inclusion defects in large castings weighing up to 50 tons, Hanhai Casting employs MAGMAsoft® solidification simulation modeling. This digital twin technology allows our foundry engineers to optimize gating systems, riser positions, and thermal gradients before liquid steel is poured.
