EAF melting period
The melting period of the traditional smelting
process accounts for 50% to 70% of the entire smelting time, and
electricity consumption accounts for 70% to 80%. Therefore, the length
of the melting period affects productivity and power consumption, and
the operation of the melting period affects the smoothness of the
oxidation period and the reduction period.
(1) The main tasks of the melting period
The massive solid charge is quickly melted and heated to oxidation temperature;
Form slag in advance and remove phosphorus early to reduce liquid steel inhalation and volatilization.
(2) Operation during melting
Reasonable power supply, timely oxygen blowing, and forming slag ahead of time.
