The pretreatment process of low niobium hot metal could be divided into three stages: the desiliconization, extraction of niobium and manganese and dephosphorization. Keywords: Hot metal treatment, desiliconization, niobium, selective oxidation, soft blowing. 1. Introduction.
Development of a Continuous Desiliconization Process in the …
An efficient continuous desiliconization process equipped with a mechanical stirrer in a hot metal runner was newly developed. The facility was installed during the revamping of No.3 blast furnace at Kobe Works, and the commercial operation started up successfully in January 2008.
Desiliconisation and Dephosphorisation Behaviours of Various Oxygen ...
To further investigate the effect of gaseous oxygen on the desiliconisation and dephosphorisation of the hot metal, a series of experiments with 0.8 kg of hot metal were carried out using different supply methods of gaseous oxygen. The detailed conditions are described in Table 2.
desiliconization. Another reason is that a silicon content of less than 0.15 % is necessary before effective dephosphorization can start. The process of hot metal desiliconization requires oxygen which can be supplied as gaseous oxygen or in form of iron oxides (“solid oxygen”) . HM De solid oxygen is endothermic and
