The Advanced System for Conducting the Electric Furnaces for Heat Treatments

Abstract:

The control of furnaces for heat treatment is a result of the permanent efforts to help work by amplifying of this capacity in solving problems of productions. The advanced system for conducting the furnaces of heat treatments has the main importance in different activities developed in hard conditions. The electric furnaces heat treatment is aimed primarily at obtaining specific temperature profile characteristic type of heat treatment imposed by technology, the heat treatments applied to heat-sensitive parts with complex configuration of alloy or operating in demanding work environments or arrangements often require temperature the furnace is kept constant with maximum deviations of 2 ÷ 3 °C above the prescribed manufacturing technology. Resolving these conditions requires accurate tracking of the desired temperature profile, goal difficult to achieve with conventional control algorithms. In this scientific work will be shown how to solve complex problems of driving an electric furnace heat treatment using the thermo regulators with algorithms type PID (proportional-integral-derivative controller ) and PID-predictive (proportional-integral-derivative - predictive controller)
