Abstract

Способ нагрева металлической шихты (31), подаваемой непрерывно в плавильную печь (30) по второй горизонтальной секции (34) нагрева, через которую проходят горячие отходящие газы из указанной печи (30), при этом указанные газы формируют фазу нагрева указанной шихты (31), отличающийся тем, что непосредственно перед подачей в указанную вторую секцию (34) нагрева шихту (31) подвергают фазе предварительного нагрева при помощи нагревательных средств, отличных от отходящих газов, поступающих из плавильной печи (30). В установке для воплощения указанного способа указанные отличные нагревательные средства предусмотрены внутри первой секции (33) предварительного нагрева, функционально соединенной с указанной второй секцией (34) нагрева посредством промежуточной секции (35) отвода газов, куда подают газы, поступающие из указанных секций (33) и (34). Указанные секции (33, 34) предпочтительно имеют форму туннеля.
