Features of modelling dynamics for heating processes of cylindrical cast iron products in gas ovens

The process of heating the billets of rolling mills from cast iron in gas heating ovens (both in covalent and casting floors) has clear requirements for temperature heating regimes. Compliance with the requirements of technology is possible with the use of automatic control devices. Programmable logic controllers are commonly used as a temperature control device. Correct operation of automation is possible because of a definite model of the heating process dynamics.
