Borovichi: the motherland of Russian refractory

Roh Tae-kyun, Diachko A.G., Smirnov O.M. Correction of innovative project’s indices subject to dynamic simulation results

A dynamic mathematical model for an innovative project of casting blocks production for the new large-diameter pipe factory in Nizhny Taghil is presented. Dynamic simulation of design operation modes showed performance gaps and much unused equipment capacity. Organizational and managerial actions were proposed and tested on he simulation which decrease the resource demand. Predictive simulation was used for analyzing the effect of random disturbances on the operation results. A control algorithm was offered and tested ensuring stable plant operation under random noises.
