Operating a blast furnace in high productivity has some challenges, as a higher production rate leads to an increased reductant consumption. Since the use of natural resources as fuel in the blast furnace relates to a great variability in quality of the reductant agent, a screening unit was implemented and an algorithm was applied in the process control to minimize these variabilities. Also, taking notice that an increased iron yield favors a lower metallic charge in the blast furnace, pig iron scrap produced in the pig casting machine was added to the blast furnace, considerably reducing the production cost of hot metal.
