Abstract

The calculated path of optimal control management of slab heating before rolling preforms is a function of the workpiece temperature parameters (center and surface temperatures) of time. While the process of implementing the optimal control heating furnaces transmission type main problem is the transition from the calculated optimal trajectories of each workpiece heating temperature setpoint to the zones of the heating furnace. The task is complicated by the uneven speed of movement blanks on the length of the furnace, and the difference in the initial thermal state of individual parties blanks. The paper deals with the realization of the optimal energy-saving mode with the help of the method for determining the set values of temperature settings for each heating zone reheating furnace. The possibilities of the method described in industrial furnace rolling mill 2000 JSC "MMK", under the existing mode of operation and the implementation of the optimal energy-saving heating mode. The main result of the implementation of the method in the form of subsystems for local control are setting values of temperatures of the heating zones. Recalculation setting occurs continuously with the speed and current thermal state of the heated billets.
