The invention discloses a method for preparing an aluminium-chromium intermediate alloy by using chromium shavings, and relates to a method for preparing an aluminium-chromium intermediate alloy and the method is used for solving the problems of high temperature, long production period and high burnt loss rate of a smelting furnace during the existing preparation of the aluminium-chromium intermediate alloy. The method for preparing the aluminium-chromium intermediate alloy disclosed by the invention comprises the following steps: step one, arranging aluminium ingot bars in the smelting furnace, sprinkling a covering agent on the surface of an aluminium solution after the aluminium ingot bars are molten, heating to 900-910 DEG C, adding 1/3-1/2 of the needed Cr shavings, and subsequently stopping stirring in the furnace; and step two, increasing the temperature of the smelting furnace to 900-910 DEG C, insulating and then evenly adding the rest Cr shavings, blowing out, stirring removing slag, heating to 900-910 DEG C again, insulating, subsequently slagging off, and casting into ingots so as to obtain an aluminium-chromium intermediate alloy. The preparation of the aluminium-chromium intermediate alloy in the invention has the advantages of short production period, low alloy burnt loss rate and low heating temperature of the smelting furnace. The method for preparing the aluminium-chromium intermediate alloy by using chromium shavings is mainly used for the preparation of the aluminium-chromium alloys.
