<p>PURPOSE:To reduce consumption and loss quantity of fluorite at the time of using low P converter slag as slag-making agent in a dephosphorizing furnace. CONSTITUTION:At the time of reusing the low P converter slag 5 obtd. at the time of decarbonize-refining molten iron already executing the dephosphorized treatment in the converter 2 and receiving the converter slag 5 removed from the converter 2 into a slag pan 3, in the condition of pre-charging auxiliary material of at least the fluorite 4, etc., in the slag pan 3, the above converter slag 5 is received, and after the above auxiliary material 4 is melted and mixed in the converter slag 5, this auxiliary material is used to the dephosphorizing treatment in the dephosphorizing furnace 1 or a ladle 6.</p> |
