Low-burning-loss high-silicon aluminum alloy smelting process

The invention relates to a low-burning-loss high-silicon aluminum alloy smelting process, which comprises the following steps of: controlling the temperature of molten aluminum to be 20-30 DEG C above the corresponding melting point of the current molten aluminum components before silicon is added by adopting a mode of controlling the temperature in stages and adding silicon in batches, and ensuring that the temperature of the molten aluminum is reduced to be below the melting point before silicon is added by absorbing heat through silicon after silicon is added so as to form a semi-solid pasty melt; and moreover, the viscosity of the molten aluminum is increased, so that the molten aluminum is not easy to float upwards, and the oxidation burning loss of silicon is reduced. And after the silicon is added, the temperature of the molten aluminum is increased to 40-80 DEG C above the melting point corresponding to the components of the molten aluminum, so that the silicon is quickly melted, the molten aluminum i
