Description
Technical field
The present invention relates to wear-resistant hammer head field, more particularly to a kind of wear-resistant hammer head of hammer mill.
Background technology
Hammer mill is widely used in the industries such as building materials, mine, metallurgy, electric power and chemical industry, wherein tup operationally
Stress is complicated, withstand shocks, extrude, shearing and contact fatigue repeated action, working condition is severe, belongs to crucial accessory, year
A large amount of metal materials are consumed, therefore, developing a kind of novel low-cost, good-toughness and high-wearing feature tup has turned into raising China
The urgent problem for solving of of hammer mill operating rate, from operating mode use requirement, the end wear position of tup will
Hardness very high is sought, shock resistance is good, and anti-wear performance is good；Tup shank installation position, it is desirable to preferable toughness, using not
Fracture, while also having certain hardness, in recent years, proof, the medium and small tup of large usage quantity, using material is used through operating mode
Expect to be single potassium steel, due to wearing no resistance, tup wear extent is big, and broken material efficiency is low, causes high energy consumption low output, always
Puzzlement business economic is fast-developing, also once improves the anti-wear performance of tup with martensite steel in the industry, and due to poor toughness, fragility is big,
Using there is phenomenon of rupture often, operating mode uses little；Rich chromium cast iron hardness is good high-abrasive material, due to fragility very very well
Greatly, easily it is broken, not yet as hammer head material, at present, medium and small tup is manufactured using double metallic composite material both at home and abroad, it is comprehensive
Close mechanical property and reach use requirement, disclosure satisfy that different operating mode use environments, be cast boundary's referred to as forth generation high-abrasive material, it is double
The complex method of metal composite tup mainly has two kinds of techniques：Liquid-solid bimetallic is compound and liquid-liquid bimetallic is combined.Wherein
There is mechanical bond in the compound interface of liquid-solid Double-metal composite hammer, bond strength is low, is also easy to produce crackle, chip off-falling and fracture and lacks
Fall into, using dangerous, and the compound interface of liquid-liquid Double-metal composite hammer is metallurgical binding, and bond strength is high, in use both
Wear-resisting and safe, the preparation method of liquid-liquid Double-metal composite hammer generally uses phenolic sand molding technique, the technique both at home and abroad
Tup mounting hole formed by fuse, moulding needs more sandbox, is equipped with tooling auxiliary tool, and operating procedure is complicated, production efficiency
Low, production cost is higher.
