The invention relates to the technical field of iron and steel smelting, in particular to a method for controlling titanium content of silicon steel and a silicon steel production method. According tothe method for controlling the titanium content of silicon steel, infrared sliding plate slag blocking equipment is adopted in the tapping process of converter smelting, and the thickness of a lowerslag layer in a ladle is less than 10 mm after the converter tapping. The process does not require the titanium content range of molten iron, the needs of titanium nitride furnace protection for blastfurnace production are met, the process cost of pre-titanium removal of molten iron is avoided. By using the process method, the content of residual titanium element in molten steel can be stably controlled within 20 ppm, and the lowest content can reach within 10 ppm, and thus the requirement of silicon steel production on the titanium content in molten steel is met.
