Quick calculation method for titanium alloy smelting burden

The invention discloses a quick calculation method for titanium alloy smelting burden. The method specifically comprises the steps of firstly according to quality and element composition requirementsof a titanium alloy cast ingot needed to be smelted, selecting sponge titanium and intermediate alloy; secondly listing out a linear equation set among an individual element composition, a usage amount and cast ingot required element content in raw materials; and according to a Cramer rule, solving a matrix corresponding to the equation set, thereby obtaining a unique solution of a usage amount ratio of the raw materials. The quick calculation method is suitable for burden calculation of smelting methods of vacuum arc remelting, plasma, an electron beam cold hearth and the like of various titanium alloys; by initially obtaining chemical components of the sponge titanium, the intermediate alloy, scraps and the like, and the quality of the cast ingot, conversion is performed to form a matrixform; the accurate unique
