<p>The present invention relates to a manufacturing method of low-silicon steel for coating a steel plate and comprises steps of: measuring the aluminum concentration of molten steel contained in desulfurizing units such as LF or VD equipment; calculating aluminum input by substituting both the aluminum concentration and a preset quicklime input into the below interaction formula; and inputting the preset quicklime and the calculated aluminum input into a slag layer and refining the molten steel after stirring the same.
