Control of metal heat treatment process in a furnace using a diagnostic system based on batch heat capacity

Аннотация

A method for determining the time at which ingots heated in a furnace achieve a predetermined thermal state is proposed, based on a real-time determination of the average heat flux density on the surface of a metal charge and the corresponding heat content increase relative to the initial state. An appropriate heating control algorithm is described, and the calculation results are presented for the example of a bogie hearth furnace.
