Cored wire is usedforsteelmaking. It can purify the liquid steel, change the impurities
shapes, improve the castability of iron and steel, improve the
using performance of steel, and significantly enhance the
ferroalloy yield rate, reduce alloy consumption as well as the cost
of steelmaking in consequence to get remarkable economic benefits.
1.Change the composition and morphology of inclusions in steel,
improvethemechanical properties of steel.
2.Reduce and eliminatenozzle blockingof steelmaking.After silicon calcium cored wires feeding and calcium treatment,
thesolidAl2O3withhigh melting point and aluminum silicate are changedinto calcium aluminate. Calciumaluminateappearsto be liquidunder the pouring temperaturebecause ofits low melting point,which helpsavoidgathering andeliminatingthe phenomenon ofnozzle clogging.
3. Improve therecovery rateof alloyelementsand stay stability.The recoveryrateof Calcium was 1% ~ 3%withthegeneral addition method,5%withpowder spraying method, and 10% ~30%after applying the line feeding method.
