Abstract
The invention relates to a process for preparing wearable ceramic bar orientation arrangement reinforced steel or iron-based casting composite material, which is characterized in that wearable ceramic bars are arranged vertically to an abrasive surface at intervals of 5-10mm and fixed in a casting mold in which mother molten metal is poured, and a wearable composite material casting is obtained after the molten metal is solidified. The invention mainly solves the problem that the common wearable material can not have wearing resistance and impact ductility at the same time, the wearable composite material casting can be prepared in the common casting conditions, and the use of the commercial wearable ceramic bars avoids the occurrence of a compound interface, so that the production process and the product performance are more stable.
Description
Technical field
The present invention relates to the metal-base composites field, the preparation technology of more specifically say so a kind of wearable ceramic bar orientation arrangement reinforced steel or iron-based casting composite material, the method for producing the composite-material abrasive foundry goods by casting technique.
Background technology
The widely used consumable accessorys in field such as metallurgy, building materials, electric power, mine adopt common wear resistant cast iron or abrasion resistant cast steel usually, and the wearability of common high-abrasive material and impact flexibility are a pair of contradiction, increase the wearability that hardness can improve material, but can reduce the impact flexibility of material simultaneously, easily cause the wear part early fracture and lost efficacy, severe patient can cause equipment or personal safety accident.Usually for of the security of assurance equipment, the sacrificial section wearability in use.
Along with industrial production technology is constantly progressive, the user is more and more higher to the requirement of high-abrasive material, not only enough toughness will be arranged, and also higher wearability will be arranged.
Wear-resistant ceramic has high hardness and wearability, but can't use under having than the thump operating mode because of its toughness is very low.
Composite can effectively solve the contradiction of material on wearability and impact flexibility, has developed various process for producing composite material at present, and casting-sinter process, casting infiltration, original position method of formation etc. are arranged.But defectives such as because of technology is stable inadequately, there is pore easily in the faying face between wild phase and the parent metal (interface), is mingled with, lack of fill-out cause piece easily, come off and early stage the damage, are difficult to obtain the product of stable performance.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, the preparation technology of a kind of wearable ceramic bar orientation arrangement reinforced steel or iron-based casting composite material is provided, ceramic rod is evenly arranged in the foundry goods, can guarantee the uniform wear of material, avoid the early stage damage that causes because of the technology instability.
Technical solution problem of the present invention adopts following technical scheme:
Wearable ceramic bar orientation arrangement reinforced steel of the present invention or iron-based casting composite material preparation technology's characteristics are wearable ceramic bar is arranged perpendicular to wear surface with the spacing of 5～10mm and to be fixed in the casting mold, pour into base metal liquid, obtain the composite-material abrasive foundry goods after solidifying.
The preparation technology's of wearable ceramic bar orientation arrangement reinforced steel of the present invention or iron-based casting composite material characteristics are that also described wearable ceramic bar is that diameter is that 3～6mm, length are the Al of 40～60mm

3, SiC or ZrO
2
The preparation technology of wearable ceramic bar orientation arrangement reinforced steel of the present invention or iron-based casting composite material carries out according to the following procedure:
A, select wearable ceramic bar, select the ZrO2 ceramic rod for the impact wear operating mode according to the wear resistance castings applying working condition; Select Al2O3 or SiC ceramic rod for the abrasive wear operating mode;
B, by casting technique swabbing in die cavity, adopt down that a staying is fixed on the die cavity abrading section with ceramic rod in loam core method or the type, the ceramic rod orientation is perpendicular to main wear surface.
C, mould assembling cast are finished casting technique and are promptly got wearable ceramic bar orientation arrangement reinforced steel or iron-based casting composite material.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention uses wearable ceramic bar, aligns with certain spacing, and is fixed on the setting position of casting mold, pours into liquid metal in casting mold, obtains the composite abrasion resistance material foundry goods after solidifying.Because the parent metal parcel is also supporting wearable ceramic bar, make the parent metal wearing and tearing through use after, exposes wearable ceramic bar, with these effectively opposing wearing and tearing.Under the prerequisite that guarantees enough impact flexibility, can increase substantially the wearability of material with the composite of the inventive method Foundry Production.
2, the invention solves the wearability of common high-abrasive material and the contradiction that impact flexibility can not get both, can under the conventional cast working condition, prepare composite abrasion resistance material,, effectively avoid the compound interface problem by using the finished product wearable ceramic bar, make production technology more stable, properties of product are more stable.
3, the present invention makes full use of the high rigidity, high-wearing feature of wearable ceramic bar as wild phase, with common antifriction alloy or normal steel casting is fertile material, process by casting obtains the wearing composite material foundry goods, technology is easy, the yield rate height, its wearability is wanted more than the Senior Three times than widely used common high-abrasive material at present, and cost increase only 20%.Not only can improve the economic benefit of manufacturing enterprise,, can prolong the parts replacement cycle, enhance productivity applying unit; Can reduce spare parts consumption, increase economic efficiency; Capable of reducing energy consumption, reduce environmental pollution.
