The invention relates to a recycling method of an LF (
ladle furnace)
scrap ladle slag inclusion, and belongs to the technical field of
steelmaking in the
metallurgical industry. The method adopts the technical scheme that the method comprises the following process steps that (1), the LF
scrap ladle slag inclusion is subjected to natural cooling,
magnetic separation, crushing and screening, and then made into refining
slag, with a particle size
diameter of 5-30mm, and with the following chemical components by
mass percentage: less than or equal to 10% of SiO2, greater than or equal to 40% of CaO, less than or equal to 12% of MgO, 18-45% of Al2O3, less than or equal to 3.0% of MnO, less than or equal to 3.0% of FeO, and less than or equal to 1.5% of S; (2), plain
carbon steel is made in a converter, the refining slag is added to a ladle during tapping, 2-3Kg refining slag is added to
molten steel per
ton, all the refining slag is added before 1 / 3 of a tapping course, and
argon blowing is conducted for 3-8min after tapping. The method has the positive effects that the method facilitates improving ladle slag adsorption
silicate inclusion capacity, reducing oxidability of the
molten steel, reducing consumption of iron and steel materials and alloys in the converter, and further improving the quality of the
molten steel.
