11. Decline of the Bessemer Process In spite of the basic simplicity, the Bessemer steel suffered from several limitations: • A large part of the heat generated through exothermic reactions is lost in the form of sensible heat of the N2 gas. So, the scrap melting ability of this process is very limited. • The 'N' content in the Bessemer steel is …

The iron obtained as part of this process is either secreted, stored inside ferritin, or employed as part of the labile iron pool. Hepcidin, the master regulator of iron metabolism, is produced and secreted by hepatocytes, where its production is regulated by iron stores and plasma iron levels. Hepcidin binds to Fpn and thereby initiates its ...
