The main areas of using digital control and modeling methods in Severstal coke and blast-furnace production are presented. The results of using a system for monitoring the composition of the gas over the charge and a system for radar measurement of the stockline in a blast furnace are described. A system for continuous monitoring of the temperature of cast iron using multiwave pyrometers and online analyzers for rapid adjustment of the composition of a sintering charge were used successfully. Laser rangefinders and a 3D-scanner are used as an example to describe methods for monitoring the condition of the blast furnace profile and determining the actual charge profile. The use of video monitoring systems based on long-wave infrared sensors made it possible to obtain the ecological effect of reduced emissions due to the reduction of the gassing of coke-oven battery doors. Determining the volume of raw materials in open warehouses using quadcopters significantly reduced the measurement cost. The developed statistical models and digital twins of processes are based on the calculation of the integral process parameters and the theoretical calculations of physical and chemical processes, including drawing up material and heat balances.
