description The invention belongs to the technical field of non-oriented silicon steel metallurgy, and relates to a non-oriented silicon steel RH (Ruhrstahl Heraeus) refining temperature control method, which adopts a process route of combined blown converter-RH vacuum refining-continuous casting, and specifically comprises the following steps: step 1, molten iron and scrap steel are loaded into a converter for converter oxygen blowing smelting, and the converter tapping temperature is controlled at 1670-1690 DEG C; step 2, performing RH vacuum refining on the molten steel after converter tapping, controlling the temperature of RH arrival molten steel to be 1600-1620 DEG C, and controlling the temperature of the molten steel after 3 minutes of RH refining circulation to be 1590-1620 DEG C; 3, the temperature of the molten steel obtained after RH refining circulation is conducted for 15 minutes is controlled to range from 1585 DEG C to 1600 DEG C; 4, after RH refining circulation is carried out for 15 minutes, RH deoxidat
