First of all, flux-cored wire feeding technology is an out-of-furnace processing technology. In order to make flux-cored wires from an alloy, powders of various alloys must be coated with a strip of mild steel. During operation, the wire feeder must overcome the slag layer at a certain speed to direct the flux-cored wire into the molten steel at the bottom of the bucket.
This can be used to deoxidize molten steel, remove sulfur, fine-tune alloy composition, and change the properties of inclusions. Proper use of flux-cored wires can effectively improve the purity of molten steel and the internal quantity of steel, thereby reducing costs. Because flux-cored wires need to be directed deep into molten steel when used, they can overcome the disadvantages of some alloy elements, such as low specific gravity, low melting point, strong affinity for oxygen in steel, difficulty in adding to the furnace or contact with slag, and secondary oxidation and combustion.
Flux-cored wire is suitable for steel smelting and casting. Used in steelmaking, it can clean the shape of steel inclusions, improve the pourability of molten steel, improve the performance of steel, and significantly increase alloy yield, reduce alloy consumption, reduce steelmaking costs, and achieve significant economic benefits.
