Industrial Sectors — 08 / Crushing, grinding & bulk material handling

Steel, Cement & Chemical Industries

Cement and steel plants destroy metal for a living. Crusher hammers, kiln components and vertical raw mill grinding elements face abrasion, impact and pressure at the same time, and the established answer is not replacement but rebuild — gouging out fatigued material, rough grinding, machining, building back up with hardfacing wire and stress relieving afterwards. Chromium-carbide and tungsten-carbide overlays are chosen for the specific wear mode, and getting that choice wrong is expensive.

What this sector demands

  • Hardfacing overlays matched to the actual wear mode — abrasion, impact, or high-pressure grinding
  • Rebuild-and-hardface capability rather than replacement, to control spare-part cost
  • Capacity for large, heavy components and long weld runs
  • Stress relieving and heat treatment after overlay to prevent cracking in service
  • Delivery inside planned shutdowns, when the whole line is down and every hour counts

How Rainbow supports it

Rainbow's welding shop runs multiple processes and hardfacing consumables, backed by heat treatment to international standards, a large machine shop for oversized components, a foundry for wear castings and a fabrication section for chutes, silos and liners. Where a component cannot be moved, in-situ teams take the work to the plant instead.

Behind it

  • ISO 9001:2015
  • ISO 14001:2015
  • In-house heat treatment & foundry

Our specialities

What we do for Steel, Cement & Chemical Industries

01
