A new technology of hydrogen bottom blowing instead traditional argon in the current converter steelmaking process is proposed herein, aim overcoming problems such as energy shortages caused by increased scrap charging, low stirring intensity blowing, high CO2 emissions, and endpoint carbon content control. The thermal effect metallurgical characteristics were investigated based on production d...

Kambara Reactor (KR) desulfurization slag used as slag-making material for converter smelting can promote early melting in the initial stage and improve efficiency of dephosphorization. However, its direct utilization a slagging increase sulfur content molten steel since KR contains 1~2.5% sulfur. Therefore, this research focuses on effect basicity precipitation behavior occurrence state order ...

The pulverized lime/limestone injection by top oxygen blowing lance during the basic furnace (BOF) process has gained much interest in recent years due to its advantages helping slag formation and consequently promoting refining reactions such as dephosphorization. In this pneumatic process, understanding motion behavior distribution of powder particles is importance for regulating designing sy...
