Abstract： |
The present invention discloses one kind of new high carbon and high tungsten high speed steel roll and its making process, and belongs to the field of high speed steel roll making technology. The high carbon and high tungsten high speed steel roll contains C 2.0-3.0 wt%, W 6.0-18.0 wt%, V 2.0-4.0 wt%, Mo 1.0-3.0 wt%, Cr 3.0-9.0 wt%, Si less than 1.2 wt%, and Mn less than 1.2 wt%, and possesses MC type composite carbide of V and W. The making process of the high carbon and high tungsten high speed steel roll includes heating high carbon and high tungsten high speed steel to 1580-1620 deg.c before deoxidizing, casting at 1400-1500 deg.c and rotary forming while adding stable magnetic field of 0.05-0.25 T to the centrifuging casting mold and rotating the casting mold at 600-1800 rpm speed. |
