The invention discloses a
wire rod for steel cord and its Al2O3
inclusion control method. The
wire rod for steel cord comprises 0.68-0.89wt% of C, 0.1-1.0wt% of Si, 0.35-0.80wt% of Mn, 0.015wt% or less of P, 0.010wt% or less of S, 0.004wt% or less of N, 0.002% or less of total
oxygen, 0.0010wt% or less of total aluminum, and the balance Fe and inevitable impurities. The Al2O3
inclusion control method comprises the following steps: allowing the content of Si-Fe and Mn-Fe-Al used after converting to be not greater than 0.02% and the content of Al in a carburant to be not greater than 0.05%; allowing the content of Al2O3 in a
refractory material at the pot liner, the pot bottom and the
slag line of a large pot to be not greater than 0.05% in the refining process and the content of Al2O3 in
lime, silica sand,
sillimanite and
wollastonite slagging materials to be not greater than 0.05%; allowing the large pot used in the
molten steel refining to be special; completing the final deoxidation and component micro-adjustment of the
wire rod for steel cord within 15min before the ending of an LF furnace refining; carrying out
argon stirring treatment of the
molten steel, wherein the
argon flow is 150-350NL / min; and allowing the content of Al2O3 in a
tundish covering agent to be not greater than 0.03% and the content of Al2O3 in a
tundish coating to be not greater than 0.04% in the
continuous casting process. The
Al content in the wire rod for steel cord is not greater than 0.001% in the invention, so the Al2O3 inclusion in the wire rod is eliminated, and the fracture rate of the wire rod in the drawing process is reduced.
