The invention discloses a control method of a two-stage auxiliary material module in a revolving furnace smelting process. The control method comprises the following steps of: firstly, adding steel scrap into a revolving furnace, and feeding molten iron into the revolving furnace; supplying oxygen to a molten iron liquid level from the top part by an oxygen lance, supplying stirred gas to the inner part of the molten iron from the bottom part, carrying out dephosphorization processing on the molten iron, lifting the oxygen lance after processing, and carrying out quick deslagging on the revolving furnace; then, supplying oxygen to a molten iron liquid level from the top part by the oxygen lance again, supplying stirred gas to the inner part of the molten iron from the bottom part, and carrying out decarburization processing on the molten iron; and after catching the carbon and lifting the oxygen lance, carrying out tapping operation, and carrying out slag splashing for furnace maintenance and finishing slag for solidification after tapping. According to the control method of the two-stage auxiliary material module in the revolving furnace smelting process, provided by the invention, functions of carrying out dephosphorization processing and decarburization processing on the molten iron are completed in one revolving furnace without additionally arranging a special dephosphorization revolving furnace. Under the condition that the consumption of lime and light calcined dolomite is reduced by 20 percent-40 percent and the quantity of slag is small, high-efficient dephosphorization is realized, and the process control requirements in dephosphorization and decarburization stages of the revolving furnace are met.
