Iron boron cored wire

The iron-boron cored wire includes a wire core and a sheath covered by a steel strip. The weight accounts for 30%-60% of the total weight of the cored wire.

When the iron-boron cored wire is fed into the molten steel, because of the thin sheath of the wire, the splash is very small when feeding the molten steel, the smoke pollution caused by gasification is greatly reduced, and the pollution to the environment is greatly reduced. It significantly reduces the probability of BN formation on the surface of the slab, effectively improves the phenomenon of cracks on the surface of the slab after wire feeding, improves the yield of the slab and the yield of boron, and the yield is also very stable.

The iron-boron cored wire is injected into molten steel by wire feeding machine equipment, which can greatly improve the absorption of calcium alloy and improve the quality of molten steel. It can improve the purity of molten steel and reduce the oxygen content and oxide inclusions in steel. Refining and feeding line is an important refining process, which plays a very important role in improving the purity of molten steel and reducing heavy skin and inclusion waste after rolling.
