The invention provides a low-titanium-content double-layer covering agent for silicon steel and a use method of the low-titanium-content double-layer covering agent. The low-titanium-content double-layer covering agent comprises an upper layer covering agent part and a lower layer covering agent part; the lower layer covering agent part is contacted with molten steel; the upper layer covering agent part is located above the lower layer covering agent part; the upper layer covering agent part comprises the following raw materials, by weight percentage, 44-62% of SiO2, 2-10% of MgO, 1-10% of CaO, greater than 0 and less than or equal to 7% of Fe2O3, 20-38% of Al2O3, greater than 0 and less than or equal to 1% of C (all), greater than 0 and less than or equal to 0.5% of TiO2, and the balance ignition lost; and the lower layer covering agent part comprises the following raw materials, by weight percentage, 15-25% of SiO2, 3-8% of MgO, 48-68% of CaO, 2-10% of Fe2O3, greater than 0 and less than or equal to 1% of Al2O3, greater than 0 and less than or equal to 1% of C (all), greater than 0 and less than or equal to 0.2% of TiO2, and the balance ignition loss. With the use of the low-titanium-content double-layer covering agent, the content of titanium in molten silicon steel can be reduced effectively.
