Model of Bof Lapping with Setted Temperature and Carbon Content

In order to increase the accuracy of process control refinement converter smelting, a series of mathematical models of controlling were developed. Melting model was created to calculate the charge (“static control”), control fuse in the process of purging (“dynamic management”) and finishing melting after the measurement of carbon content and temperature of the bath without interrupting the purge and calculation of reductants. The influence of control actions on the process of finishing converter smelting was studied.

Control of the Temperature Mode of BOF Process

We analyze the existing methods of the bath temperature control. We study direct and indirect methods of controlling the temperature in the course of purging. We define the dependence between the output parameters of converter melting and the bath temperature. Finally, we elucidate the results obtained by implementing the dependencies in the algorithms of control of the BOF process
