Background technology:
Rich chromium cast iron is the abbreviation of high chromium white antifriction cast iron, is a kind of excellent property and is subject to the special wear-resistant material paid attention to. It is with the wear resistance more much higher than steel alloy, with the toughness more much higher than general white cast iron, intensity, simultaneously it also has good high temperature resistance and corrosion resistance concurrently, produce in addition convenient, cost is moderate, and is described as one of the most excellent anti-abrasive wear material in the present age. But still have to be strengthened for its wear resistance of tup technical field, thus extend its work-ing life. High-vanadium high-speed steel not only has very high hardness and suitable toughness, and has excellent wear resistance, and therefore as wear-resisting material of new generation, high-vanadium high-speed steel receives much concern. Research shows, the wear resistance of high-vanadium high-speed steel is more than 3 times of rich chromium cast iron, is more than 10 times of high mangaenese steel, has been used to the multiple wearing pieces such as roll, tup, ball grinding machine lining board and rotor body. Therefore both alloy phases are combined form the alloy with two kinds of common advantages of alloy and be applied to the production of tup very necessary.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of wear resisting property good, it may also be useful to the life-span is long, the production technique of the hot composite hammer head of the high-vanadium high-speed steel that metallographic structure is trickle and low alloy steel.
