Core wire is a type of ferroalloy in which various additives (deoxidizers, desulfurizers, modifiers, alloys, etc.) to be added to molten steel or iron are crushed to a certain particle size and then made into a composite material of any length using cold rolled mild steel strip, which mainly consists of three aspects: gestation, extra-hearth refining and alloying of special elements.
Types of cored wire include: dicalcium wire, pure calcium wire, calcium-silicon wire, calcium-aluminum wire, rare-earth wire, titanium-iron wire, carbon wire and so on.
Cored wire is suitable for steelmaking and casting. It can purify the form of inclusions, improve the castability of steel, improve the performance of steel, significantly increase the alloy yield, reduce alloy consumption, reduce the cost of steelmaking, and achieve significant economic benefits.
1, core wire ferroalloy is also conducive to regulating and controlling the content of oxidizable elements and trace elements, which can greatly improve the alloy yield, reduce smelting costs, shorten the smelting time, and accurately control the composition.
2,Core wire plays a role in purifying steel and partially changing the nature and shape of inclusions, improving the quality of steel and improving the casting condition.
3,Core wire can be divided into two types: internal stretching and external placement. The mechanical equipment required for wire feeding is simple and reliable, and covers a small area. In particular, internally drawn core wire is more suitable for use in narrow places.
With the advantages of uniform core composition and high filling rate, core wire can be used in many industries, effectively reducing the production cost and storage time in the smelting process.
