| description | The invention relates to a furnace pressure control method and device for an annealing furnace. The furnace pressure control method is applied to each furnace section of the annealing furnace, an injecting pipeline for injecting protection gas is arranged at each furnace section, and a flow controller is arranged on each injecting pipeline. The furnace pressure control method comprises the following steps that the current furnace pressure value of the annealing furnace is obtained, whether the furnace pressure value meets the pre-set furnace pressure range is judged, when the pre-set furnace pressure range is met, based on the furnace pressure value, the flow correction coefficient of the injecting pipeline in a target furnace section and the flow rating of the corresponding injecting pipeline, and the flow correction value for correcting the flow controlled by the flow controller on the corresponding injecting pipeline is obtained; and based on the flow correction value, correcting control is conducted on th |
