Raw material preheating production method for smelting titanium slag

The invention relates to the field of titanium slag smelting methods, in particular to a raw material preheating production method for smelting titanium slag, which reduces the smelting power consumption of the titanium slag and improves the production benefit of the titanium slag, comprises a titanium slag electric furnace and a heat exchange device, and comprises the following steps : a, introducing the tail gas of the titanium slag electric furnace as a heat source into the heat exchange device; b, carrying out heat exchange on a raw material for smelting titanium slag arranged in the heatexchange device and tail gas of the titanium slag electric furnace so as to finish preheating; and c, introducing the preheated raw material for smelting titanium slag into the titanium slag electricfurnace for smelting production, and finally obtaining a product. According to the invention, the electric energy consumption of the raw material heating part in the titanium slag smelting process issaved, the overall energy c
