Sintering main exhaust fan frequency regulation method

The invention relates to a sintering main exhaust fan frequency regulation method. The sintering main exhaust fan frequency regulation method includes the steps that a sintering wind box final temperature signal is acquired, and the sintering wind box final temperature signal is sent to a main exhaust fan unit through a sintering unit in a communication manner; query tables corresponding to the material type, the material layer thickness and the sintering pipeline negative pressure of the sintering unit are established; the material type and the material layer thickness on a sintering pallet are acquired by the main exhaust fan unit through an Ethernet I/O acquisition module; the sintering pipeline negative pressure and temperature are detected; and when the material type, the material layer thickness and the sintering pipeline negative pressure and temperature reach set conditions, the operation frequency of a main exhaust fan is regulated by the main exhaust fan unit according to thefinal temperature signal
