To provide a continuous casting method of a wear-resistant steel in which in continuously casting a wear-resistant steel containing Ti, even the reduction reaction of SiO2 in a mold powder by Ti in a molten steel progresses and SiO2 in the mold powder decreases, the viscosity rise after the mold powder melts is suppressed, and the molten steel is made to enter between a mold and a solidified shell, thereby a surface defect of a longitudinal crack, slag inclusion, a gas catching bubble or the like can be prevented, and to provide the wear-resistant steel obtained by the same.
In the continuous casting method continuously casting the molten steel of the wear-resistant steel having a composition containing C and Ti in a prescribed amount, a mold that performs the continuous casting is vibrated by the amplitude of 3.0-9.0 mm, the frequency of at least 60 times/minute and less than 120 times/minute, the mold powder containing 0.1-0.5 mass% of a fatty acid is injected in the mold, the casting speed is made 0.6-1.0 m/minute, and the continuous casting is performed.
