Titanium ingot production method

The invention discloses a titanium ingot production method, and belongs to the technical field of titanium ingot production. The titanium ingot production method comprises the steps that a distilled and purified sponge titanium lump is placed in an electron beam cold bed smelting furnace in a vacuum state to be smelted, an electron gun scans the center position of the top of the titanium lump during smelting, the peripheral part of the top of the titanium lump is scanned after the depth of the center position of the top is no longer reduced, titanium liquid is controlled to slowly flow to the edge of the titanium lump, and the depth of a molten pool is reduced; and repeating the operation of scanning the central position and the peripheral part of the titanium lump, so that the titanium liquid flows into the crystallizer, and pulling out a qualified titanium ingot. By means of the titanium ingot production method, the complex procedures of dicing, crushing, mixing, gathering, screening, packaging and the like
