The following are the advantages of the twostage reduction system: (1) In the prereduction process, a high degree of ore reduction near the end point of the reaction is saced for the sake of a high reaction rate.
Steel and sustainability: new ideas, better solutionsThe direct conversion of steel plant wastes into useful byproducts, without combustion, is an efficient use of energy streams. With a number of pilot and demonstration plants already in operation, this biotechnology is well on its way to contribute to the environmental sustainability of the steel industry.
