High quality core wire alloy for steelmaking
The core-clad wire is to crush various additives (deoxidizing agent, desulfurizer, modifier, alloy, etc.) to be added into the molten steel or molten iron into a certain particle size, and then include them into a composite material with an arbitrary length by cold rolled low-carbon steel strip. Based on different alloy powder, it can be divided into: calcium-silicon cored wire, calcium-silicon wire, calcium-barium silicon wire, barium aluminum wire, calcium-aluminum wire, calcium-iron wire, pure calcium wire, etc. Winding appearance similar to coil.

Useage
Cored wire technology is a kind of refining method developed on the basis of jet metallurgy technology. Cored wire is suitable for steel making and casting. It can purify the form of steel inclusions, improve the castability of molten steel, improve the use performance of steel, significantly improve the recovery rate of alloy, reduce the alloy consumption, reduce the cost of steel making, and achieve significant economic benefits.
Advantage
1. It is beneficial to adjust and control the content of readily oxidizable elements and trace elements, greatly improve the alloy yield, reduce the smelting cost, shorten the smelting time and accurately control the composition.
2. It can purify molten steel and partially change the property and form of slag inclusion, improve the quality of molten steel and the casting state.
3. Clad core wires are divided into two types: internally drawn type and externally laid type. The mechanical equipment required for wire feeding is simple and reliable, and the floor area is small. Particularly, internally drawn type sheathed core wires can adapt to narrow places.
