The utility model discloses a device for automatically adjusting air intake of an annealing kiln. The device comprises a flue oxygen content sensor arranged in a flue of the annealing kiln, wherein an output end of the flue oxygen content sensor is connected with an input end of a PID (proportion integration differentiation) regulator, and an output end of the PID regulator is connected with a hearth air input adjusting device of the annealing kiln. The device for automatically adjusting air intake of the annealing kiln has the characteristics of energy conservation, emission reduction, consumption reduction and the like. As a temperature control auxiliary device of the annealing kiln, the device for automatically adjusting air intake of the annealing kiln is capable of improving the control accuracy of the furnace temperature and improving the annealing quality of casts, so that the product percent of pass is improved, and the production cost is saved.
