Compared with available treatment process, the present invention raises the nitial wear resistance of high manganese steel and has the features of simple production process, stable surface performance, etc.
Description
Technical field
The present invention relates to a kind of surface aging treatment process that improves high manganese steel initial wear-resisting performance, particularly integral body is passed through the high mangaenese steel after tough processing of water and/or the tough processing of water add low temperature aging processing and mechanical workout, adopt surface heated method that ageing treatment is carried out on its surface.After the ageing treatment of surface, the interior tissue of high mangaenese steel still be the austenite of high tenacity, and surface structure is even dispersion is distributing tiny on austenitic matrix carbide hard particle, thereby has improved the wear resisting property of high mangaenese steel at the use initial stage.Belong to the material surface modifying field.
Background technology
High mangaenese steel is as high-abrasive material, and aspect the abrasive wear or cutter skiving damage of resisting under thump, the big stress, its wear resistance is that other materials is incomparable.
High mangaenese steel normally formerly integral body be heated to about 1000 ℃ insulation, the tough processing of water subsequently obtains single-phase austenite and/or the tough processing of water and adds low temperature aging and handle and obtain the structural state that austenite adds minor amount of carbide and use down, because the austenite in the high mangaenese steel is more stable, and has good plasticity and toughness, crack growth rate is very low, thereby high mangaenese steel is as safe as a house in use reliable.
High mangaenese steel why have high wear resisting property be since high mangaenese steel under bigger shock load or contact stress effect, its top layer austenite can produce work hardening rapidly, and surface hardness is sharply raise, thereby has improved wear resisting property.Applied shock load is big more, and the hardness on himself top layer is high more.When surface hardness is improved, and inner still for having the austenite of excellent toughness.Therefore, the high mangaenese steel after the tough processing of water has good wear resistance, and the while can also be born bigger shock load and do not broken.Under the plus load continuous action, though the case-hardening layer will constantly be worn away, the austenite on inferior top layer will continuously form new work hardening layer, thereby guarantees that high mangaenese steel in use maintains high wear resisting property always.This special performances of high mangaenese steel is widely used in the mechanized equipments such as metallurgy, mine, building materials, railway, electric power, coal it for a long time, as grinder hammerhead, tooth plate, rolled mortar wall, dig wall machine bucket tooth, ball grinding machine lining board, railway switch etc.
But high mangaenese steel is at the initial stage of using, because austenitic hardness is on the low side, its top layer will have bigger dimensional change under the first secondary action of plus load, thereby reduce the contact precision between the friction pair, will have influence on the work-ing life at initial stage of high mangaenese steel at last.In order to improve the initial wear-resisting performance of high mangaenese steel, people have carried out research extensively and profoundly from the integral body that improves high mangaenese steel or two aspects of hardness on top layer, and have obtained many achievements in research, and make raising have by a relatively large margin been arranged in work-ing life of high mangaenese steel:
The first, improve its work-ing life by the integral hardness that improves high mangaenese steel.
1, the alloying of high mangaenese steel
At present, the high mangaenese steel that we use always is the ZGMn13 type, and its chemical ingredients is roughly C:0.9～1.2%, Mn:11～14%, Si:0.3～0.6%, S≤0.04%P≤0.07%.Adding alloying elements on this basis is one of main means that improve at present the high mangaenese steel wear resistance.The main trend of high mangaenese steel alloying research is by adding Cr, Mo, V, Ti, rare first-class alloying element in traditional composition, thereby obtains carbide particle that disperse distributes to improve the wear resistance of high mangaenese steel on its austenitic matrix.Publication number is that CN1068857's " multicomponent alloy malleablized high-Mn steel " and publication number is that " rare earth boron micro-alloyed high manganese steel " patent of CN1644744A has reported that respectively the intensity and the wear resistance of high mangaenese steel are greatly enhanced after adding multicomponent alloys such as rare earth, Mo, Ti, W and micro-B element and rare earth on the basis of common high mangaenese steel chemical ingredients.And publication number to be the patent " railroad frog special-purpose nitrogen austenite Mn-Cr steel " of CN1451777 reported adds a certain amount of nitrogen, chromium, vanadium, rare earth and copper on the basis of common high mangaenese steel chemical ingredients, make to have improved 50%-80% in work-ing life of High Manganese Steel Frog.
2, disperse insert process
Disperseing insert process is in the castingprocesses of high mangaenese steel, within it the alloy-steel wire of portion's castingin certain diameter and quantity and obtain a kind of method of matrix material.This material through the tough processing of water after because alloy-steel wire becomes the martensite fibrous bundle of rectangular net distribution in inside, thereby the matrix material of the higher martensite reticulin fiber bundle of intensity that obtains on the austenite of high mangaenese steel, distributing.
3, whole ageing treatment method
Single austenitic sosoloid is adopted whole ageing treatment, make the carbon precipitation in the austenite and separate out, carbide particle that like this will even dispersion is distributing hard on soft austenitic matrix with the form of carbide.Such tissue will be favourable to shock resistance abrasive wear and the raising wear resistance that improves high mangaenese steel.Publication number is that the patent " a kind of novel manganese steel of high-wear resistance " of CN 1038468 has been reported after high mangaenese steel is carried out alloying, adopt the suitable tough treatment process of water, make on the austenitic matrix of high mangaenese steel the disperse spherical second mutually wear-resisting particle that distributes, improved the wear resisting property of high mangaenese steel.
The second, improve its work-ing life by the surface hardness that improves antiwear high manganese steel.
1, explosion hardening method
The explosion hardening method is to utilize the time (10 of extremely lacking after the blast
-9S) high pressure (3 * 10 that produces in
7KPa) affact on the surface of high mangaenese steel, it is out of shape under stress and obtains certain thickness hardened layer.The surface hardness of hardened layer can reach 300～500HB.Pressure is higher, and hardened layer is thicker.
2, the surface alloying method of high mangaenese steel
The surface alloying method is to be coated with brush cast at mo(U)ld face with the coating that contains alloying element in modeling process, the alloy powder fusing and be diffused into the certain depth on foundry goods top layer under heat effect of high mangaenese steel when casting is solidified the back and is formed and the high mangaenese steel composition tissue top layer different with performance.Publication number is the method that the patent " top layer or partial gradient reinforced wear-resistant manganese steel composite material and preparation technology " of CN1616706 has adopted surface alloying, making the strengthening layer on surface is that the higher titanium carbide+martensite of hardness+Jie's stable austenite, intermediate layer are the complex tissue structure of the titanium carbide+martensite+stable austenite of gradient gradual change, and heart portion still is the higher austenite of toughness.Like this, guaranteeing that high mangaenese steel has under the condition of higher safety in utilization, because the raising of the hardness on top layer, and make it obtain very high wear resisting property.
The surface alloying method also can directly be inserted the casting mold mold cavity surface and realize with the high-abrasive material of high rigidity.Like this, under the heat effect when molten steel is cast, high-abrasive material will with the high mangaenese steel welding, have transition layer therebetween.Publication number is that the patent " a kind of technology that improves service life of high manganese steel wear resistant part " of CN1785554 has adopted rapid steel, hard alloy steel etc. as high-abrasive material, after the casting and common high mangaenese steel welding by molten steel, also can make the matrix material that is obtained have very high wear resistance.
In sum, improving the method for high mangaenese steel integral body or surface hardness, all is fruitful for improving high manganese steel initial wear-resisting performance.No matter but the sort of method, all there are some bigger drawbacks in they on selection and production method.For the method that improves the high mangaenese steel integral hardness, though the hardness on top layer has improved, the hardness of material internal also and then improves, thereby the plasticity of material internal and toughness will reduce, and has influenced the safety in utilization of high mangaenese steel.In the alloying of high mangaenese steel, increased the production cost of material owing to the adding that alloying element is arranged.And for the surface burst hardening process, the site requirements when handling in the management of explosive and to explosion hardening is all very strict; For the surface alloying method, the alloying degree of depth on surface and content is wayward or high-abrasive material and high mangaenese steel in conjunction with the not firm work-ing life that also influences high mangaenese steel.Therefore, in order to improve the initial wear-resisting performance of high mangaenese steel, guaranteeing that high mangaenese steel itself has under the condition that performance advantages such as good toughness, the carrying sclerosis is high, wear resistance is good do not suffer damage, develop the surface hardness that a kind of production method effectively simple and low production cost improves high mangaenese steel is complete necessity.
