Method for carrying out calcium treatment on low-silicon steel by adopting high-calcium wire

The invention discloses a method for performing calcium treatment on low-silicon steel by adopting a high-calcium wire, which is characterized in that the high-calcium wire is adopted for performing calcium treatment in the production of low-silicon aluminum-containing killed steel, the piece weight of the high-calcium wire is 288.78 g/m, the powder particle weight is 58.78 g/m, the diameter of a cored wire is 9.3-10.2 mm, and the thickness of an iron sheet is 1-1.2 mm; the smelting process before and after LF refining and wire feeding comprises the following steps: after the first furnace of steel is subjected to LF refining, firstly heating to melt slag and desulfurize, adjusting components to reach the standard, off-line measuring temperature and determining oxygen, then feeding a certain amount of aluminum wire according to the oxygen content of molten steel, then feeding the high-calcium wire, measuring temperature and determining oxygen after wire feeding, softly blowing for a certain time, and hoisting
