The invention discloses an argon oxygen refining low-carbon ferrochromium process endpoint carbon content and temperature control method. In the method, molten iron crudely refined in an electric furnace is poured into an AOD (Argon Oxygen Decarburization) furnace, oxygen is blown from a top gun for quick decarburization, when carbon content is reduced to a critical value, oxygen and argon mixed gas is blown from a bottom gun to carry out decarburization reaction, and finally pure Ar gas is blown for several minutes to make residual oxygen in the molten iron continue to react with carbon so as to further reduce the carbon content; when the carbon content reaches a preset target, ferrosilicon is added under the stirring of the Ar gas to carry out reduction; and on the basis of the thoroughanalysis of a smelting process mechanism, partial mathematical models in the low-carbon ferrochromium production process are established, and based on the models, an inference control method is adopted to accurately control the carbon content and the temperature of a molten bath, the hit rate of an endpoint is greatly improved, the output is increased, the quality of iron alloy is improved, the consumption of raw materials and energy is reduced, the production cost is reduced, and the economic benefits are increased.
