The invention discloses a generating device and method for hot air in front of a blast furnace, an iron smelting device and method and iron and belongs to the technical field of blast furnace iron smelting. The hot air generating device comprises a hot air system, an oxygen system, a hot air pipeline, a first oxygen pipeline and a mixing pipeline. The hot air generating method is achieved based on the hot air generating device. The smelting device comprises the hot air generating device, a main hot air pipe and the blast furnace. The smelting method is achieved based on the smelting device. The iron is smelted through the smelting method in the smelting device. By means of the hot air generating device and method and the iron smelting device and method, the oxidation rate of a defect position of the inner wall of a hot blast furnace shell can be reduced while the generation amount of nitrogen oxides in the hot blast furnace is reduced in the iron smelting process. 本发明公开了种高炉前热风生成装置和方法、铁的冶炼装置和方法及铁，属于高炉炼铁技术领域。该热
