Abstract
The invention discloses high-wear-resisting high-manganese steel and a preparation method thereof. The high-wear-resisting high-manganese steel comprises the following components in percentage by weight: 6.0-14.0% of Mn, 1.00-1.25% of C, 0.45-0.60% of Si, less than or equal to 0.03% of S, 1.8-2.2% of Cr, 0-2.0% of Ti, 0-1.0% of Mo and 80.0-90.0% of Fe. The preparation method comprises the following steps of: A. smelting, namely, adding Mn, C, Si, P, S, Cr, Ti, Mo and Fe to a furnace, and smelting; B. modification treatment, namely, carrying out modification treatment on smelting liquid in the step A by adopting a modifier; C. molding by casting: namely, adding the smelting liquid in the step B to a casting mold and molding to obtain a primary product; D. thermal treatment: namely, carrying out water toughening treatment on the primary product in the step C, and then carrying out aging treatment at 250-800 DEG C. The invention aims at providing the preparation method of the high-manganese steel with high toughness, high strength, high wear resistance and long service life.
Description
Technical field
The present invention relates to a kind of wear and shock-resistant high mangaenese steel, the invention still further relates to a kind of method for preparing this wear and shock-resistant steel.
Background technology
Mn13 is high manganese wear-resistant steel, is one of the most frequently used material in opposing thump, lost material.The characteristics of high mangaenese steel maximum have two: the one, and external shock is larger, and himself surface layer abrasion-proof is higher; The 2nd, along with the wearing and tearing gradually of cementation zone, new work hardening layer can successively form.Be specially adapted to impact abrasive wear and the heavily stressed abrasive wear operating mode of pulverizing, be usually used in manufacturing ball grinding machine lining board, hammer head of hammer crusher, jaw plate of jaw crusher, cone crusher rolled mortar wall, crushing wall, excavator bucket teeth, headwall, railroad turnout, the shock resistances such as grip-pad of tractor and tank, wear-resistant foundry goods.High mangaenese steel is also for armour plate, safety locker steel plate etc.
Along with socioeconomic development, the intensity of machinery work is also increasing, becomes important influence factor the work-ing life of material, and therefore also more and more higher to the requirement of material, this also just substitutes current material in the urgent need to the material of a kind of more long life.
Due to the formula of high mangaenese steel and the characteristic on the preparation method, can not heat-treat strengthening in prior art, after thermal treatment, the flaky carbide intercrystalline precipitation of organization internal, become fragile foundry goods, and decrease toughness seriously shortens work-ing life of material.Materialogy ABC is pointed out, if carbide is separated out the replacement Intergranular precipitation with intracrystalline in heat treatment process, replace the sheet network with spherical particle, form the tissue of a kind of high rigidity Second Phase Particles disperse at the high tenacity matrix, will increase substantially hardness and the work-ing life of material.Prepared this kind of high manganese steel material based on this theory.
Summary of the invention
The objective of the invention is, in order to overcome the defect that existing high mangaenese steel can not heat treatment reinforcement, provides a kind of preparation that is easy to, and toughness is good, and wear resistance is high, the high mangaenese steel that the life-span is long; The method of this high mangaenese steel of preparation is provided simultaneously.
For achieving the above object, the present invention adopts following scheme:
The heat treated antiwear high manganese steel of a kind of energy is characterized in that composed of the following components by weight percentage:
A kind of high abrasion high mangaenese steel as above is characterized in that composed of the following components by weight percentage:
The present invention is a kind of method of antiwear high manganese steel as mentioned above for preparing, and its feature comprises the following steps:
A, melting
Mn, C, Si, P, S, Cr, Ti, Mo, Fe are joined in stove and carry out melting;
B, the rotten processing
Adopt alterant to the processing of going bad of the melting liquid in steps A
C, casting
Melting liquid in step B is added to moulding in mold, obtain first product;
D, thermal treatment
First product in step C is carried out to the tough processing of water, then under 250 ℃-800 ℃, carry out ageing treatment.
Preparation method as mentioned above, its feature 1 be described alterant by Re5%, Ti15%, Ca5%, V0.5-2%, Mo0-2%, Mg15%, Fe56-60% forms, the 0.2-0.5% that the consumption of described alterant is molten steel weight.Feature 2 is to have changed the characteristics (after thermal treatment, at crystal boundary, form netted separating out and make toughness drop) that common high mangaenese steel can not carry out ageing treatment under 250 ℃-800 ℃, after described high mangaenese steel carries out ageing treatment under 250 ℃-800 ℃, separate out spherical hard particles at intracrystalline and see Fig. 1, increased toughness, intensity and the wear resistance of material simultaneously.
In sum, the present invention with respect to its beneficial effect of prior art is:
The present invention adds the self-control alterant in castingprocesses, the processing of going bad, by the thermal treatment process in technical solution of the present invention, material is carried out to the tough processing of water again, improve material structure, make material see Fig. 2 at the inner globular carbide that generates of crystal grain, and can not form at crystal boundary the carbide network of sheet, such tissue increases the toughness of material, intensity and wear resistance to some extent, thereby extends the work-ing life of material.
The accompanying drawing explanation
One of microstructure schematic diagram that Fig. 1 is the wear and shock-resistant steel;
One of microstructure schematic diagram that Fig. 2 is the wear and shock-resistant steel.
