Thermal Spray Coating for
Steel Plants
Heavy-duty surface protection and dimensional reclamation for continuous casting rollers, table rollers, sleeves and shafts that run hot, abrasive duty in integrated steel plants and rolling mills.
Components We Coat in Steel Plants
Continuous casting roller reclamation and re-profiling
Table roller anti-skid and anti-wear coatings
Straightener and pinch roll wear surfaces
Furnace skid rails and hearth roll thermal protection
Morgoil bearing journal and shaft build-up before grinding
Typical Outcome
Typical outcome: worn rollers returned to drawing size and put back on line instead of being scrapped.
Coating Processes Used
Twin wire arc spray for high deposition build-up
Wire flame spray (metallizing) for shaft and journal reclamation
HVOF for dense carbide wear faces on finishing rolls
Coating Materials Specified
13% chrome steel and 420 martensitic stainless wire
Molybdenum bond coat for adhesion on smooth journals
NiCrBSi self-fluxing alloy for hot abrasion
WC-Co (86/10/4) for carbide wear surfaces
