Calculation method for adding amount of low-carbon low-silicon aluminum killed steel LF refining aluminum wire

The invention provides a method for calculating the addition amount of low-carbon low-silicon aluminum killed steel LF refining aluminum wires, and relates to the technical field of ferrous metallurgy. The calculation method for the addition amount of the low-carbon low-silicon aluminum killed steel LF refined aluminum wire comprises the following steps: firstly, obtaining the acid-soluble aluminum content of a converter ladle sample molten steel component, and determining the initial addition amount M of the aluminum wire according to the acid-soluble aluminum content; then the sulfur content, the acid-soluble aluminum content and the molten steel weight in LF refining entering molten steel are obtained, a first-time aluminum wire adding amount calculation model is established accordingly, and the first-time adding amount M1 of an aluminum wire is determined; and after the initial heating and slagging operation of the LF is completed, the acid-soluble aluminum content in the LF refining process is obtained,
