| titleOfInvention | Method for melting ultra-low carbon steel in LF (ladle furnace) |
| abstract | The invention relates to a method for melting ultra-low carbon steel in an LF (ladle furnace). The method for melting the ultra-low carbon steel is characterized by comprising the following specific steps of (1) carrying out argon blowing and slagging on molten steel; (2) after breaking slag blankets open, adding aluminium to the molten steel; (3) carrying out electrode heating on the molten steel; (4) weighting lime in a feed bin before heating the molten steel; (5) controlling temperature; (6) lifting up an electrode; (7) finely adjusting the alloy according to the laboratory reports of a sample II; (8) after the components of alloy are qualified, carrying out fire feeding; and (9) stopping argon blowing. The method for melting the ultra-low carbon steel has the advantages that the top slag of the molten steel is completely melted by blowing lots of argon and fully slagging before heating the molten steel; the bottom argon blowing is controlled during heating the molten steel, or the argon is closed in the earlier stage of heating the molten steel, so that the opportunity that the molten steel is in contact with the electrode is reduced; aluminium and lime are added in batches; the opportunity of increasing the carbon content in the smelting process is effectively reduced by reducing the heating frequency in a smelting process and other manners; and the content of end point carbon is reduced, and the quality and the property of the product are improved. |
