The invention discloses a production method for a low-phosphorous low-sulfur anti-sulfur pipeline steel continuous casting round billet. The production method comprises the processes of converter smelting, LF refining, VD vacuum treating and continuous casting. According to the production method for the low-phosphorous low-sulfur anti-sulfur pipeline steel continuous casting round billet, a molteniron pretreatment technology is canceled, consumption of passivated magnesium used in the molten iron pretreatment technology is reduced, therefore, consumption of non-renewable resource magnesium isreduced, and the purpose of reducing the production cost is achieved; and meanwhile, splashing in the molten iron pretreatment process is avoided, and production safety is guaranteed. The specification of the anti-sulfur pipeline steel continuous casting round billet is phi 300-600 mm; the product inclusion types comprise an A fine system at the 2.0 level or below, an A coarse system at the 2.0 level or below, a B fine system at the 2.0 level or below, a B coarse system at the 2.0 level or below, a C fine system at the 2.0 level or below, a C coarse system at the 2.0 level or below, a D finesystem at the 2.0 level or below, a D coarse system at the 2.0 level or below, an A, B, C and D coarse system at the 6.0 level or below and an A, B, C and D fine system at the 6.0 level or below; andthe DS grade is at the 2.0 level or below.
