Summary:The invention discloses a method for introducing a silicon carbide-based synthetic material to improve slag resistance of an ultralow carbon-magnesium-carbon material and belongs to the technical field of preparation of refractory materials for ferrous metallurgy. The method comprises the following steps: sufficiently and uniformly mixing a SiO2-based natural ore with waste slag and a carbon source, putting into a high-temperature furnace, and preparing a SiC-based synthetic material in an inert gas atmosphere; sufficiently mixing the SiC-based synthetic material with an ultralow carbon-magnesium material according to a certain ratio, and carrying out molding, drying and high-temperature thermal treatment, thereby obtaining the silicon carbide-based synthetic material improved ultralow carbon-magnesium-carbon material; finally carrying out a slag resistance experiment by using a static crucible method. By adopting the method, on premise that the content of carbon of a MgO-C material isreduced, the slag resist
