Abstract
A double metal composite cast wear-resistant hammer head consists of a wear-resistant layer and a tenacious layer, wherein the thickness of the wear-resistant layer is 0.50 to 0.67 times that of the hammer handle; the wear-resistant layer is made of composite wear-resistant material containing ingredients such as C, Si, Mn, Cr, W, etc., while the tenacious layer is made of composite tenacious material containing ingredients such as C, Si, Mn, etc. Effectively solving the thorny problem of fitting difficulty of wear-resistance and tenacity, the metal composite (ZK2 wear-resistant alloy) cast wear-resistant hammer head, compared with hammer heads of high-manganese steel material, has the advantages of long service life (4 to 6 times increase), simple production technology and high performance-price ratio and is an ideal hammer head product for hammer pulverizers.
Description
Technical field
The utility model relates to a kind of tup, a kind of specifically bimetal composite casting wear-resistant hammer head.
Technical background
The broken tup of the hammer of sector applications such as present domestic metallurgy, mine, cement, building materials, electric power, highway generally adopts potassium steel (Mn13) material, tup with this material manufacturing can not have been given play to the potassium steel internal potential, be that preliminary work hardening rate is not enough, cause in the tup use not wear-resisting, too early spalling failure; Then toughness is not enough to adopt the higher material of wearability to make tup, and easy fracture influences equipment life.
For understanding the problems referred to above, (patent No.: 97200813) provide a kind of is the composite wear-resistant hammerhead of one with high hardness weldable wearproof alloy cast moulding body and the weldering of tup parent to Chinese patent " a kind of composite wear-resistant hammerhead ", is widely used in industries such as mine, cement, power plant, metallurgy.This utility model is levied at tup parent damaged part, be inlaid with high hardness weldable wearproof alloy cast moulding body, and wherein molding body is multiple shape, selects as required to change.The utility model has the advantages that,, improved wearability because one deck high hardness wear-resisting alloy (HRC-55) is inlayed by the impaired portion of tup, and cheap.
But above-mentioned patent is to need wear-resisting position welding one deck wearing layer at tup, except the casting technique of whole tup, also needs at its local welding wear plate, processing technology complexity, cost height.
Technology contents
It is simple that the technical problem that the utility model will be separated provides a kind of production technology, can make wearability and toughness obtain a kind of bimetal composite casting wear-resistant hammer head of optimum Match.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of bimetal composite casting wear-resistant hammer head, to form by wearing layer and ductile layers, and the thickness of wearing layer is the 1/2-2/3 of hammer handle thickness.
Wearing layer material of the present utility model is the composite abrasion resistance material that contains compositions such as C, Si, Mn, Cr, W, and ductile layers is then for containing the compound toughness material of compositions such as C, Si, Mn.
The Casting Technology of the utility model bimetal composite casting wear-resistant hammer head is: with two stoves molten metal of the above-mentioned heterogeneities of melting respectively, wait to melt the back and divide order to pour in the same casting mold and the molten iron that guarantees the high-abrasive material part requiring in the weight range in regulation all the time.Two kinds of metal bonding layers, the tup after the cast form are two kinds of steel grades and different mechanical properties:
Tup working face (wearing layer) mechanical property: HR C60～65 ak, 8.6～9～J/cm
2
Tup non-working surface (ductile layers) mechanical property: δ s (Mpa) δ b (Mpa) δ 5 (%) Ψ (%) ak (J/cm
2)
200～206 535～545 17～19 28～32 40～45
The utility model metal composite (ZK2 antifriction alloy) casting wear-resistant tup has solved wearability effectively and toughness is difficult to coupling ground difficult point problem, compare for the potassium steel tup with material and to have improved 4～6 times of service lifes, and production technology is simple, product price ratio height is the desirable tup product of hammer mill.
