Method for machining abrasion-resisting steel bar for quartz sand bar mill

The invention discloses a method for machining an abrasion-resisting steel bar for a quartz sand bar mill. The continuous casting technology is adopted, the tapping temperature is 2400+/-5 DEG C, the temperature of a ladle is maintained at 2300 DEG C, and the temperature of a tundish is maintained above 2130 DEG C. Steel drawing is conducted when the liquid level of molten steel is located at the one-fourth position of the tundish. According to the method for machining the abrasion-resisting steel bar for the quartz sand bar mill, the production cost is low, and the service life of abrasion-resisting steel is long and is 6-7 times that of common abrasion-resisting steel.
