First of all, alloy cored wire feeding technology is an out-of-furnace refining technology. To make alloy cored wire, various alloy powders need to be coated with low-carbon steel strip. When in use, the wire feeder needs to traverse the slag layer at a certain speed to send the alloy cored wire into the molten steel near the bottom of the ladle.
This can be used to de-oxygenate the molten steel, remove sulphur, fine-tune the alloy composition, and alter the properties of inclusions. The correct use of alloy cored wire can effectively improve the cleanliness of the molten steel and the intrinsic quantity of the steel, thereby reducing costs. Since the alloy cored wire needs to be sent deep into the molten steel when in use, it can overcome the disadvantages of some alloy elements, such as their low specific gravity, low melting point, strong affinity for oxygen in the steel, and their difficulty in being added to the furnace or coming into contact with the slag, as well as secondary oxidation and burning.
Cored wire is suitable for steelmaking and casting. Used in steelmaking, it can purify the form of steel inclusions, improve the castability of molten steel, improve the performance of steel, and significantly improve the yield of alloys, reduce alloy consumption, reduce steelmaking costs, and achieve significant economic benefits.
