Description
Technical field
The present invention relates to metal material field, especially relate to a kind of alloy that is applicable to manufacturing high rigidity cold roll, and the manufacture method of this alloy.
Background technology
Because cold roll is to work under the condition of stressed complexity such as bending, distortion, extruding, at this time the part top layer is subjected to the stress more much higher than heart portion, the surface also will constantly be worn simultaneously, therefore must make quench-hardened case at the cold roll body of roll through hard surfacing, this quench-hardened case should have enough hardness, intensity, wear resistance, and body of roll heart portion must keep enough plasticity and toughness for the effect of the load that can withstand shocks.
If the hardness of the cold roll body of roll is less, easily in the working roll body of roll part permanent deformation appears, " roll marks " that promptly is commonly called as in cold-rolled process.During rolled sheet material, should " roll marks " defective will pass to steel plate, influence strip quality and product percent of pass, and increase the roll consumption amount, increase cost.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art, a kind of alloy composition and manufacture method thereof that is used to make the high rigidity cold roll is provided.
Realize a kind of alloy that is used to make cold roll of the object of the invention, the weight percentage of chemical ingredients is in the alloy: C is 0.9～1.2%, Si is 0.85～1.25%, Mn is 0.40～0.60%, Cr is 2.50～5.50%, and Ni is 0.25～0.45%, and Mo is 0.25～0.45%, V is 0.05～0.15%, and all the other are Fe and unavoidable impurities.Use the cold roll top layer of this alloy manufacturing can have good hardness.
