Development of a method for discrete-continuous inverting control of pressure control circuit inside a heating furnace

The article addresses the problem of designing an inverting regulator for controlling the pressure in a furnace for metal heating prior to rolling. Based on actual engineering data, a regression model is constructed with the elements of differential equations describing the in-furnace pressure with high accuracy, taking into account various technological factors (the position of the gate, the total gas flow into the furnace, and the operation of the metal unloading gates). Based on the obtained model and considering the features of the pressure circuits, a new discrete-continuous inverting pressure control method was designed and modeled, taking the operation of unloading machines into account.
