Embodiment 1
[0058] Manganese ore (TMn=42.8%, SiO 2 =16%, TFe=11.6%, P=0.13%, S=0.016%), lime, coke are used as raw materials after drying, crushing and grinding, and the ingredients (weight %) are: manganese ore 70%, lime 10% , coke 20%, the prepared material is used as a spare material of the manganese ore mixture after being mixed; meanwhile, aluminum powder is prepared, which is 30% of the amount of the manganese ore mixture. Use a thin steel belt to wrap the prepared manganese ore mixture and aluminum powder together, in which the aluminum powder is wrapped in the center with aluminum foil, and the manganese ore is wrapped in the periphery of the aluminum foil, and then the outside is pressed with a thin steel belt to make a diameter of 40mm and a length of 500mm , cored wire weighing 2.5kg.
[0059] In a 500kg level converter thermal simulation test furnace, load 200kg of scrap steel, induction heating to 1650 °C, take initial steel samples, measured [C] = 0.2%, [Si] = 0.4%, [Mn] = ...
Embodiment 2
[0062] Manganese ore (TMn=42.8%, SiO 2 =16%, TFe=11.6%, P=0.13%, S=0.016%), lime, coke are used as raw materials after drying, crushing and grinding, and the ingredients (weight %) are: manganese ore 80%, lightly burned 10% stone, 10% coke, the prepared material is mixed as a spare material for the manganese ore mixture; at the same time, aluminum powder is prepared to be 25% of the manganese ore mixture. Use aluminum foil to wrap the aluminum powder in the center, wrap the prepared manganese ore mixture on the periphery of the aluminum foil with a thin steel strip, and then press it tightly to make a cored wire with a diameter of 40mm, a length of 500mm, and a weight of 2.5kg.
[0063] In a 500kg-class converter heat simulation test furnace, load 200kg of scrap steel, induction heating to 1650 ° C, take the initial steel sample, measured [C] = 0.22%, [Si] = 0.34%, [Mn] = 0.3%, [ P] = 0.02%, [S] = 0.02%.
[0064] Insert 2 cored wires into the molten pool, and blow bottom-blo...
Embodiment 3
[0066] Manganese ore (TMn=42.8%, SiO 2 =16%, TFe=11.6%, P=0.13%, S=0.016%), lime, coke are used as raw materials after drying, crushing and grinding, and the ingredients (weight %) are: manganese ore 80%, lightly burned 10% stone, 10% anthracite, the prepared material is mixed and used as a spare material for the manganese ore mixture; at the same time, aluminum powder is prepared, which is 30% of the manganese ore mixture. Use a thin steel belt to wrap the prepared manganese ore mixture and aluminum powder together, in which the aluminum powder is wrapped in the center with aluminum foil, and the manganese ore is wrapped around the aluminum foil, and then pressed tightly to make a 40mm in diameter, 500mm in length and 2.5kg in weight cored wire.
[0067] In a 500kg-class converter thermal simulation test furnace, load 200kg of scrap steel, induction heating to 1650 ° C, take the initial steel sample, measured [C] = 0.25%, [Si] = 0.4%, [Mn] = 0.2%, [ P] = 0.02%, [S] = 0.02%....
