Mining Week Kazakhstan 2025 closed on 26 June after three busy days inside the MultiLogic Sport Complex Zhastar in Karagandy. Thousands of engineers walked the aisles hunting safer chain drives, lighter shackles, and cleaner ore flow ideas. Our booth drew mine owners, OEM buyers, and logistics planners who quizzed us on Grade 120 roundlink chains, DIN 745 shovel shackles, and ESGready galvanised fittings. We logged their questions, took notes during panel talks, and boiled the event down to five clear trends every chain or shackle buyer should track.

1 Compact Mining Chain Rules the Longwall

Speakers from ArcelorMittal Temirtau and ERG shared data on downtime driven by chain stretch. They switched to DIN 22252 compact links forged from 23MnNiCrMo54 and quenched into the 43–46 HRC window. The shorter pitch cuts flight bar whip, while the higher alloy lifts break load 25 %. Our live demo chain handled 1 600 kN without necking, and visitors ran hands over the weld—no underfill, no slag.

2 Shackle Geometry Shrinks but Strength Climbs

Traditional coal shackles carry bulky side plates that snag flights. Two Kazakh conveyor builders now bolt pad-less twin outboard shackles (see second carousel image). Machined radii shed fines, and forged 42CrMo4 keeps impact energy above 32 J at −20 °C—vital for Karagandy winters. Tests at booth C-14 showed zero crack after 25 000 reverse bends.

3 ESG Push Drives ZincNickel Coatings

Environmental panels hammered carbon footprints, so buyers asked how chain finish cuts lube wash-off. We compared black oxide, hotdip zinc, and zincnickel. Labs prove zincnickel slashes rust by 5× and halves grease top-ups. Freight carriers like KTZ loaded coated chain samples; they prefer longer shelf life for steppe rail trips.

5 Transport Chaos Makes Local Stock Critical

Logistics panels showed rail rates up 28 % YoY; customs queues stretch at Dostyk. Buyers want ready-made chains in Shymkent or Karagandy, not six-week sea freight. We secured a regional warehouse partner and will stage 400 tons of G80 and G100 chain plus DIN 745 shackles by April 2026. Visitors wrote preorders on the spot.
