EAF oxidation period

EAF oxidation period
The oxidation period is the main process of oxidation smelting, which can remove phosphorus, gas and inclusions in steel.
When the scrap steel is completely melted and reaches the oxidation temperature, more than 70% to 80% of phosphorus is removed and enters the oxidation period.
In order to ensure the progress of the metallurgical reaction, the oxidation start temperature is 50-80℃ higher than the melting point of molten steel.
The main tasks of the oxidation period:
Continue dephosphorization to the requirement----dephosphorization;
Decarburization to the lower limit of specification----decarburization;
Remove gas, remove inclusions----two removes;
Increase the temperature of molten steel----heating up.
