Abstract
The utility model provides an abrasion-resistant hammer of a crusher. The abrasion-resistant hammer comprises a hammer handle and a hammer body. A working surface on the hammer body consists of a base material layer and a composite layer, the composite layer comprises base metal and hard ceramic particles, and the hard ceramic particles are staggered to form a regular mesh spread in the base metal. The hard ceramic particles are arranged to form the regular mesh, the hard ceramic particles and the molten base metal are subjected to metallurgical combination reaction under the action of the molten base metal at high temperature, the local temperature is reduced due to a heat absorption effect of the hard ceramic particles, the course of crystallization is shortened, and further diffusion of elements in the hard ceramic particles is stopped, so that a good metallurgical transitional combination effect of the hard ceramic particles and the base metal is achieved, interface bonding is firm, abrasion resistance and tenacity are unified organically, the overall performance of the hammer of the crusher is obviously improved, and the abrasion-resistant hammer can be widely applied to abrasion resistance in fields of mines, electric power, metallurgy, coal, building materials and the like.
Description
Technical field
The utility model relates to a kind of grinder hammerhead, particularly a kind of wear-resistant grinder hammerhead.
Background technology
Hammer mill is industries such as metallurgy, mine, building materials and electric power disintegrating apparatus commonly used; Tup is wherein main vulnerable part; Its operation principle is to rely on the tup of rotation at a high speed to clash into the purpose that gets into the material in the cracking cabin and reach comminuting matter, and the main failure forms of tup is wearing and tearing and fracture.For a long time, the wear resistence of grinder hammerhead is poor, and service life is short, changes frequently, is the key factor of restriction material crush efficiency.Therefore development of new hammer head material and shape technology becomes problem demanding prompt solution the service life of improving tup.
The grinder hammerhead of present domestic employing mainly contains the monoblock cast tup: related material have potassium steel (Mn13) (CN200710152334.0), medium carbon alloy steel (CN1050566A), abrasion resistant Mn-W-Ti casting steel (CN1068637C), low-alloy steel (40CrMnSiMoRe), high carbon chromium nickel-molybdenum alloy steel and rich chromium cast iron etc.; Composite hammer head: comprise double-fluid double metal composite casting tup, castingin inlay or the box-like tup of soldering group (CN200320116032.5, CN91218917.7, CN201316649Y, CN93245615.4, CN2257218Y, CN2564248Y, CN2283517Y); Surface overlaying or whole built-up welding tup (CN1419990A, CN1517173A); CN101530904A explains that mainly the method with centrifugal casting obtains the apparatus and method that WC particle strengthens the base steel composite material tup; CN201300204Y discloses the method that adopts hot composite casting tup, and CN200920088270.7 discloses a kind of compound wear-resisting alloy hammer head; CN101314145A discloses a kind of grinder hammerhead with ceramic wearing coat with disappearance mould and casting infiltration preparation; CN200510096149.5 discloses a kind of iron base composite material tup and casting method thereof; CN200510043187.4 discloses a kind of WCp and has strengthened the iron-based skin layer composite material with the complexing agent technology; CN95113785.9 discloses a kind of local composite material and manufacturing approach thereof.For monoblock cast steel alloy tup, though it has high obdurability, in running, be difficult for rupturing, because the integral hardness of tup is lower, and the M in the tissue
3The hardness of carbide such as C is not enough to resist the thump abrasive action of material, so wear no resistance, service life is short.Although people attempt to improve the wear resistence of tup through adjusting measures such as alloying component and improvement Technology for Heating Processing, its result manufacturing cost often significantly increases, and the wear resistence raising is very little; For monoblock cast rich chromium cast iron tup, easy fracture then is the main cause of its premature failure in the running.And the top composite hammer head of mentioning, the complicated process of preparation that has, controllability are not strong, and composite bed comes off under percussion during the actual use that has, does not have the due wear-resisting effect of composite bed.
The utility model content
The purpose of the utility model is to provide a kind of can satisfy the high performance grinder hammerhead that uses under the complex working conditions such as various wearing and tearing, impact.
The utility model provides a kind of so wear-resistant grinder hammerhead; Form by hammer handle and hammer body; Said hammer working face (zone that withstands shocks and wear and tear) on one's body is made up of substrate layer and composite bed, and this composite bed is made up of the ceramic on metal particulate reinforced composite.
Said ceramic on metal particulate reinforced composite is made up of substrate metal and hard ceramic particles piece, and wherein the hard ceramic particles piece is staggered into netted being distributed in the substrate metal of rule.
The volume of the mesh portion that said hard ceramic particles piece constitutes accounts for 20～80% of composite bed volume.
The hard ceramic particles piece becomes regular net distribution in the tup working region in this tup that has a composite bed, improves its shock-resistant and anti-wear performance.Hard ceramic particles is a kind of in aluminium oxide, carborundum, tungsten carbide, silicon nitride, the titanium nitride or any several kinds, the hard ceramic particles piece that is formed by sintering or bonding; Substrate metal is potassium steel, steel alloy, high chrome, ordinary carbon steel, casting pig or spheroidal graphite cast-iron.
Compare with prior art, the utility model has following beneficial effect:
The utility model is arranged into the hard ceramic particles piece regular netted, and under the high temperature action of substrate metal liquid, metallurgical combination reaction takes place for hard ceramic particles and substrate metal liquid; Because the heat-absorbing action of hard ceramic particles has reduced local temperature, shortened crystallization process simultaneously; Having hindered the element in the hard ceramic particles further spreads; Combine thereby make hard ceramic particles piece and substrate metal form the excellent metallurgical transition, the interface combines firmly, wearability and toughness organic unity; Gained grinder hammerhead overall performance significantly improves, and can be widely used in wear-resisting fields such as mine, electric power, metallurgy, coal, building materials.
