The invention provides a method for producing beta-hemihydrate gypsum by annular kiln waste heat. The method concretely comprises the steps of: by utilizing waste heat of a kiln body generated by a sintered product after burning and the sintered product, selecting a coal-fired pinkeye with the temperature of 280-500 DEG C, feeding 300-800kg of industrial desulfurization gypsum, controlling the air speed of induced air at 11-15m/s, and then fully heating and removing 3/2 crystal water of gypsum to completely generate the beta-hemihydrate gypsum, collecting, recovering, screening, and aging to produce the beta-hemihydrate gypsum product. The beta-hemihydrate gypsum can be produced under the condition without any investment; industrial waste resources are fully utilized under the condition of completely ensuring the quality of the produced product; the energy source is saved; investment on production equipment is not needed; the fire coal of burning gypsum is also not needed; and power is saved, and any waste gas pollution is not generated.
