Analysis of measures used to reduce energy expenditures shows that methods in which a single parameter is changed are ineffective. Coordinated adjustment of several parameters is required. Theoretical analysis reveals the combinations of parameters with the greatest effect. The influence of the granulometric composition of the sinter on the blast-furnace efficiency is considered in terms of the influence...
The influence of elevated pressure on the reduction processes and gas dynamics in the blast furnace is analyzed. With scope for greater air injection and greater upper and lower pressure differences, increase in gas pressure at the charge hole boosts furnace productivity and reduces the CO consumption in the reduction of iron from wustite, thanks to the briefer batch residence in the isothermal zone...
