The invention discloses a 
smelting process for efficient slagging and desulfurization of LF aluminum killed steel. The 
smelting process for efficient slagging and desulfurization of the LF aluminum killed steel comprises the following steps that S1, converter 
steelmaking is carried out, and the end point temperature of a converter is controlled within 1610-1660 DEG C; the adding amount of 
scrap steel is less than or equal to 70 tons; and a strong bottom blowing mode is adopted in the later converter blowing stage to enhance 
molten pool stirring. According to the 
smelting process for efficientslagging and desulfurization of LF aluminum killed steel, converter tapping, 
argon blowing 
station and LF refining tasks are adjusted through 
process design to form a three-in-one refining process ofconverter tapping, 
argon blowing 
station and LF refining, LF slagging work is advanced, a rapid slagging process 
system is formulated, 80% or above of slagging 
slag materials are added in the tappingprocess through design optimization, and 
slag melting is promoted by fully utilizing tapping steel flow 
impact kinetic energy, 
molten steel sensible heat and 
ladle bottom 
argon blowing stirring kinetic conditions; an argon 
station adopts a top-bottom strong stirring proper deoxidation process, 
slag is rapidly formed to promote steel slag reaction, top slag reduction pre-desulfurization is realized, and LF slagging desulfurization burden is reduced; and an LF target is heated once to basically complete slagging and desulfurization tasks.
