Vanadium-containing hot-rolled wire rod for wear-resistant and anti-corrosion port machine steel wire rope, production method of vanadium-containing hot-rolled wire rod and steel wire

The invention relates to the technical field of wire rod production, in particular to a vanadium-containing hot-rolled wire rod for a wear-resistant and corrosion-resistant port machine steel wire rope, a production method of the vanadium-containing hot-rolled wire rod and a steel wire. The vanadium-containing hot-rolled wire rod for the wear-resistant and corrosion-resistant port machine steel wire rope comprises, by weight, 0.73%-0.77% of C, 0.17%-0.35% of Si, 0.45%-0.65% of Mn, not larger than 0.020% of P, not larger than 0.020% of S, 0.02%-0.04% of V, not larger than 0.10% of Cr, not larger than 0.05% of Ni, not larger than 0.05% of Cu, not larger than 0.05% of Mo, not larger than 0.05% of Ti and the balance Fe. W < = 0.05%; and the balance of Fe and inevitable impurities. According to the vanadium-containing hot-rolled wire rod for the wear-resistant and anti-corrosion port machine steel wire rope, the sorbite rate is larger than or equal to 90%, centreless martensite and grain boundary cementite are ado
