Abstract

Disclosed are a high-boron high-vanadium high-speed steel and a method for preparing the same. Pig iron, scrap steel, ferrochromium, ferromanganese, ferroboron, ferrovanadium, industrial pure iron, ferromolybdenum, ferrotungsten, ferrosilicon and ferrotitanium are subjected to smelting at 1580-1600° C. and refining to obtain a liquid steel. The liquid steel is subjected to superheating, and directional solidification at a casting temperature of 1420-1430° C., and cooled to room temperature to obtain the directionally solidified high-speed steel.
