Ca Wire

Pure Calcium Cored Wire is solid calcium metal compacted inside a low-carbon steel sheath, fed into the ladle during secondary metallurgy. Calcium boils near 1484 C — below steel-ladle temperature — so direct addition flashes off and oxidizes before it can work; the steel jacket carries the Ca below the slag line, where it releases at depth for controlled recovery. Dissolved calcium reduces alumina and modifies hard, angular Al2O3 inclusions into rounded, low-melting calcium aluminates. This curbs nozzle clogging during continuous casting and lifts transverse ductility and fatigue life. Typical uses cover EAF and BF-BOF clean-steel routes, line-pipe and forging grades, and engineering steels needing tight inclusion control. Injection speed and length are tuned to the target Ca/S and total oxygen, with addition rates commonly around 50-200 g Ca per tonne of steel. The 9 mm wire carries about 195 g/m of Ca at >= 98% purity, sheathed in low-carbon steel and wound on ~1.8-2.0 t coils for stable payout. Each lot ships with COA and MTC, multi-regional sourcing, CIF Marmara or Gebze bonded stock, 20 MT FCL. Send your grade, Ca/S target and coil spec for an RFQ.
