The invention belongs to the field of titanium alloy raw materials, and particularly relates to a method for evaluating the proportion of non-metal oxide inclusions in an intermediate alloy for titanium alloy, which comprises the following steps: S1, carrying out microscopic structure observation and shooting on a metallographic sample after sampling, inlaying, coarse grinding, fine grinding and polishing treatment on the intermediate alloy for titanium alloy to obtain a plurality of metallographic sample photos; s2, calculating the proportion of non-metal oxide inclusions for each metallographic sample photo, and formulating an evaluation grade; and S3, counting the calculation result of the nonmetal oxide inclusion proportion of each metallographic sample photo, converting the corresponding evaluation grade into a final grade, and defining the use risk of the final grade. The method solves the problem that the non-metal oxide inclusions in the intermediate alloy for the titanium alloy cannot be accurately d
