The invention belongs to the technical field of refractory materials, and a preparation method of low carbon magnesium carbon rod head is proposed. A preparation method of low carbon magnesium carbon rod head was proposed. The composite powder of aluminum, magnesium oxide and titanium oxide was used as precursor. When the composite powder is introduced into the mixing process of low carbon magnesium carbon rod head material, the composite powder which accounts for 2~6 % of the raw material weight of low carbon magnesium carbon rod head material is introduced into the blank in the form of fine powder, and the blank is formed by isostatic pressing to obtain the green body of low carbon magnesium carbon rod head. The green body is placed in the heat treatment atmosphere with N₂ content greater than 99.99 vol%, and the heat treatment is carried out at 1150°C~1450°C for 2~5 hours; finally, a titanium nitride in-situ composite low carbon magnesium carbon rod head material was formed. The invention improves the thermal shock resistance, oxidation resistance and erosion resistance of low carbon magnesia carbon refractory.
