First of all alloy cored wire feeding technology is a kind of out-of-furnace refining technology, the production of alloy cored wire requires various alloy powders to be wrapped through the low carbon steel belt, in the use of the wire feeder needs to be used to traverse the slag layer at a certain speed, the alloy cored wire will be fed into the steel water near the bottom of the steel ladle.

Thus the liquid steel for deoxidation, desulphurisation, alloy composition fine-tuning, inclusions denaturation and other treatments, the correct use of alloy core wire can effectively improve the cleanliness of the steel and steel intrinsic amount, so as to achieve the purpose of reducing costs, due to the use of alloy core wire need to be sent to reach the depths of the liquid steel, so that it can overcome the specific gravity of certain alloying elements are light, low melting point, and the oxygen in the steel of the affinity of not easy to be added in the furnace or Contact with slag, secondary oxidation burns and other unfavourable factors.
