Embodiment 1
[0016] A method for rapid deoxidation in the smelting process of an LF refining furnace comprises the following steps:
[0017] (1) After the molten steel enters the LF station, the aluminum iron containing 40% of aluminum is added at one time according to the aluminum composition of the initial molten steel, so that the aluminum content in the steel reaches 0.04%-0.05%, and at the same time, low-aluminum slag balls are added (mainly composed of aluminum: 20%, CaO: 10-15%, Al 2 o 3 : 40%), the addition amount is 150 kg, and the active lime addition amount is 2.0Kg / T steel.
[0018] (2) Power transmission slag, the power transmission process is divided into 3-5 times, each time add 0.2Kg / T steel molten steel deoxidizer (the main component is CaC, the content is more than 60%) for submerged arc, after 5 minutes of power transmission, The top slag melts and stops power transmission.
[0019] (3) Adjust the flow rate of argon gas so that the diameter of the slag surface is blow...
