The invention relates to a small billet low silicon steel flocculating flow prevention method. The end point carbon content is controlled to be not lower than 0.03% by adopting a high drawing point blowing technology in a converter in the converter process; bottom argon blowing is carried out at a flow of 0.12 m<3>/min.t or less before tapping, and stirring is carried out for 5-8 min; ferroaluminium-manganese and iron barium calcium silicon are adopted to carry out common deoxidation, iron barium calcium silicon is added preferably, and then ferroaluminium-manganese is added; the addition amount of ferroaluminium-manganese is corrected according to tapping carbon and the point blowing time in the point blowing melt process; only fluorite and lime are used in the slagging process in a refining step; an appropriate calcium/aluminum ratio is controlled; the argon blowing time is controlled, wherein the argon blowing time of primary tank molten steel is 8-12 min, and the argon blowing time of continuous cast tank molten steel is 5-8 min; and the skilling time is not shorter than 10 min. The method reduces the flocculating flow phenomenon of small billet low silicon steel, improves the continuous cast furnace quantity to 8 or above, avoids molten steel return accidents, and reduces the cost.
