Abstract
The utility model relates to a hard metal-steel composite material wear-resisting product which comprises a hard metal working part, a steel matrix, and a mutual soluble transition layer between the hard metal working part and the steel matrix. The utility model has the advantages that the utility model has the high hardness high wear resistance of the hard metal and has the high intensity high tenacity of the steel matrix, not only the range of application of the hard metal is widened, but also the production cost of the wear-resisting product is reduced conspicuously, and service lives of the hard metal, the steel matrix, and the wear-resisting product are prolonged. The utility model is favorable to both producers and users.
Description
The utility model relates to the wear-resisting product of a kind of carbide alloy-steel composite material.
Carbide alloy has obtained application more and more widely because of its intrinsic characteristic.But, because its hardness height, fragility is big, can't be used to make the big vulnerable part of the power of being hit, in addition, also there is the cost height in whole hard alloy spare, the drawback that one-time investment is big, many users want with also with not rising, individual really no small problem.
The utility model is that its working portion is wear-resisting carbide alloy, but is unlikely to initial failure because containing steel substrate for society designs a kind of novel wear-resisting product, has also just overcome defect of high cost simultaneously.
The wear-resisting product of carbide alloy-steel composite material of the present utility model contains carbide alloy working portion 1 and steel matrix 2, its feature: it also contains between carbide alloy working portion 1 and steel matrix 2 and by the two transition zone 3 that dissolves each other and form.
The wear-resisting product that the utility model relates to comprises various rolls (format roll, thread delivering roller, smoothing roll, guide roller, peeling rollers, crimping seaming roller etc.), various hot and cold punch, die, punch-die, drift, core bar and the swaging dies of making mould also comprise the machine components that multiple cutter, folder, measurer and working face are easy to wear.In fact, it is the workpiece face that these products have only part surface, and the effective thickness of these working faces general only 0.02～10mm among a small circle in.The utility model is exactly that (thickness 3～10mm) is after preliminary treatment with the hard alloy blocks of definite shape, be fixed on the assigned address in the metal mold chamber, utilize the molten steel heat of cast to make the top layer fusion that contacts with molten steel, between the two, form a transition region of dissolving each other, solidify the latter two seam and constitute advanced composite material (ACM) product blank, promptly get required product through machining.
In order to realize the satisfactory metallurgical binding of carbide alloy and steel, to note two especially.The first will be selected the mutual matched materials of performance for use, and carbide alloy can be used TiC base, WC base (W.Ti) C, Cr
3C
2Base etc., and the liquidus temperature of steel should differ 10～30 ℃ than the sintering temperature of carbide alloy, and the difference of the thermal coefficient of expansion of the two is not more than 1.5*10
-6/ ℃; If but when mating with steel with the carbide alloy of machinable heat treatment, the two heat treatment process parameter should be basic identical.It two is to carry out following preliminary treatment to hard alloy blocks; (prescription is HY-2 multiple-effect oil emulsion 1.5kg to → 80 ℃ of washing lotions of clear water washing, sodium carbonate 0.15kg, nitrous acid steel 0.1kg, add water 100kg) in shake in → 250 ℃ of baking ovens of rinsing → clear water flushing in oven dry → pickling (pickle is 14～18% aqueous hydrochloric acid solutions, adds the methenamine of acid solution total amount 0.5～1%) → → 80 ℃ of 2～3% sodium carbonate aqueous solution of washing neutralization → flowing water clean → in the supersaturation borax solution that seethes with excitement, flood several minutes → in 200～230 ℃ drying box, be incubated 2 hours.
The wear-resisting product of carbide alloy-steel composite material had both had the high rigidity of carbide alloy, and high-wearing feature has the high strength of steel again, high tenacity, thereby the phenomenon of initial failure in use can not appear, not only prolongs working life, and enlarged application; Secondly, can significantly reduce the consumption of Hardmetal materials, thereby can be the strategic resource of national saves valuable, and significantly reduce the production cost of wear-resisting product, thereby factory and user can both therefrom get profit.
Accompanying drawing 1 is the structural representation of carbide alloy-steel composite material roll.
Accompanying drawing 2 is the structural representation of carbide alloy-steel composite material stretching die.
Among the figure, 1, the carbide alloy working portion, 2, steel matrix, 3, transition zone.
Claims (1)
- The wear-resisting product of a kind of carbide alloy-steel composite material contains carbide alloy working portion (1) and steel matrix (2), it is characterized in that, between described carbide alloy workpiece (1) and steel matrix (2), also contains the transition zone (3) that the two dissolves each other and forms.
