Description
Technical field
The present invention relates to roll technology field, relate in particular to a kind of containing alloy steel material and preparation method thereof for yttrium roll.
Background technology
Roll is the central module of wire rod machine, and gadolinium part is carried out to gadolinium processing processed, makes metal produce the main tool of viscous deformation.Roll working load is large, bears very large gadolinium pressing pressure and torsional moment, and has very strong shock load and very large mass force; In addition, the Working environment of roll is harsh, bear very high temperature, has again water coolant, is in the cold and hot lower work that accompanies each other, serious wear.
High carbon and chromium cast steel, the several types such as ordinary steel and Wimet.High carbon and chromium cast steel is owing to there being certain wear resistance, and low price, is therefore widely used, and high carbon and chromium running roller has 13Cr13WMoV and 18Cr20WMoV with the conventional material of steel.Because these two kinds of steel hardness and wear resistance mainly rely on the carbide Cr of chromium
