Abstract
The present invention relates to novel manganese steel with high wear resistant performance, which belongs to alloy materials. Alloy materials of rare earth molybdenum or vanadium, titanium, etc. are compounded and added to high-carbon and high-manganese steel; by dispersion treatment, a metallographic structure with spherical second phase wear resistant particles dispersed and distributed on an austenite matrix of solid solution strengthening is obtained. The material has favorable wear resistant performance under the working condition without strong impact and has favorable wear resistant performance under the working condition with strong impact. The present invention has the advantages of simple production technology, low cost and abundant material source, and is a good material for manufacturing a wear resistant component of equipment of metallurgy, mining, construction and construction material machinery.
Description
The invention belongs to alloy material, a kind of novel manganese steel of high-wear resistance.
High mangaenese steel is the time-honored wear-resistant material of a kind of use.Because it has higher impelling strength and work hardening characteristic, still be widely used in making so far fragmentation, grinding and the constructional engineering machinery of mine, building material machinery excavation, loosen the soil and the part easy to wear of metallurgical equipment.Because serious wear, the production consumption of its vulnerable part is very big.In order further to improve the work-ing life of high mangaenese steel, seek to be applicable to the new steel grade under the different operating modes, the researchist of various countries is at the remodeling of high mangaenese steel with carried out a series of research work aspect the alloying more in recent years.Introduce among European patent EP-0141804Al, in high mangaenese steel, add (weight ratio) Cr:0-3%, Ni:0-4%, Mo:0-2.5%, Ti:0.05-0.09%, V:0-0.05%(Ti+V ≈ 0.05%-0.14%), be used for improving wear resistance.U.S. Pat 4494988 is introduced, in Mn13, add (weight ratio) Cr:4%-6%, certain content of Ni4%-6% and N, its wear resistance russian patent SU850725 that also increases is presented in the high mangaenese steel and adds (weight ratio) Cr:0.5%-2%, V:0.1%-0.5%, Ti0.2%-0.6%, Nb:0.1%-0.3%, N0.5-0.65% also can improve its wear resisting property.
This shows that in order to improve the wear resisting property of high mangaenese steel, people have added more more valuable rare alloy material in high mangaenese steel, have increased substantially the cost of material, its ratio of performance to price is unreasonable.And production technique is also complicated more.
The purpose of this invention is to provide a kind of rich alloying element of China that in high mangaenese steel, adds, utilize simple production technique, thereby can obtain the good novel manganese steel material of wear resisting property.
The present invention is compound interpolation rare earth, molybdenum or alloy materials such as vanadium, titanium in high carbon high manganese steel.Handle by disperse, obtain solution strengthening austenite on the distributing metallographic structure of the spherical second mutually wear-resisting particle of disperse.The weight percent of its composition is: C:0.8-1.6, Mn:8-15, Si:0.2-1.0, Mo(or V): 0.1-0.6, Ti0.05-0.6, RE0-0.06, S≤0.05, P≤0.1, surplus is Fe and unavoidable impurities.Foundry goods is handled through disperse.
The weight percent of best proportioning of the present invention is: C:1.0-1.3, Mn:9-12, Si:0.3-0.6, Mo(or V): 0.25-0.45, Ti:0.1-0.2, RE:0.02-0.04, surplus is Fe and unavoidable impurities.
New steel grade provided by the present invention not only has good wear resistance under non-strong impact working condition, and has good wear resisting property under the intense impact operating mode equally.Its material source is abundant, and cost is lower, and production technique is simple.It is the good material of making wearing piece in metallurgical mine, building materials, the building engineering equipments such as crusher tooth plate, tup, backplate, rolled mortar wall, ball grinding machine lining board, excavator bucket teeth, Dou Liang, headwall.
Embodiment: with 250 * 500 jaw crusher swing tooth plates of table 1 numbering 1,2,3 compositions trial-production, foundry goods is handled through disperse, and installation is used then, can broken hardness be the tough and tensile brown corundum of HV1800-2200.Show with the machine test-results: it is 2.75T/Kg that composition is numbered single mill amount of 1, and relative wear resistance is 1, and 2,3 the single mill amount of being numbered is respectively 6.32T/Kg and 5.74T/Kg, and relative wear resistance is respectively 2.30 and 2.10.Composition is numbered 2 and 3 invention steel grade and improves 1.3 times and 1.1 times respectively work-ing life than the common high mangaenese steel (Mn13) that is numbered 1.
