Variable parameter adjusting method and device in hot rolling production process, equipment and medium

The invention discloses a variable parameter adjusting method and device in the hot rolling production process, equipment and a medium. The variable parameter adjusting method in the hot rolling production process comprises the steps that in the process of monitoring actual parameter values of key process parameters in a first production procedure of a hot rolling product in real time, a target interface is displayed; comparing the monitored actual parameter values with reference values of the key process parameters to determine whether the key process parameters are abnormal or not; under the condition that the comparison result indicates that the first key process parameter is abnormal, alarm information indicating that the first key process parameter is abnormal is output; and in response to the input of the user for the first program identifier corresponding to the first key process parameter, displaying an adjustment interface of the first key process parameter, so that the user adjusts the variable para
