Description

A kind of alterant for wear-resistant steel forging
Technical field
The present invention relates to alterant technical field, particularly relate to a kind of alterant for wear-resistant steel forging.
Background technology
Alterant is widely used in metallurgy industry, and Metamorphism treatment is to improve alloy microstructure, improves alloy mechanical property Conventional effective means, especially in refining alloy microstructure, and then improve the intensity of alloy, hardness, percentage elongation, impact flexibility and The aspects such as heat stability, have important function and meaning.Conventional alterant is divided into alloy inoculant and compound alterant two big Class.Alterant element in alloy inoculant exists with simple substance and/or intermetallic compound form, melts also after adding metal bath It is diffused in melt, plays metamorphism.Alterant element in salt alterant exists with compound form, adds metal bath Afterwards with molten metal generation displacement reaction, alterant element enters melt, plays metamorphism.
It is believed that the feature mechanical property to wear-resistant steel forging such as graphite form in wear-resistant steel forging tissue, size, quantity Energy, machinability have vital impact, control the graphite features in wear-resistant steel forging tissue and are i.e. obtained in that required Wear-resistant steel forging ferrum property.
If controlling the growth of primary austenite in wear-resistant steel forging process of setting, making primary austenite is that spatial network is sent out Exhibition, then can limit the growth of graphite during eutectic freezing, is conducive to obtaining the graphite that shape bending, size are tiny, thus Reach to improve the purpose of wear-resistant steel forging mechanical property.
Summary of the invention
The technical problem existed based on background technology, the present invention proposes a kind of alterant for wear-resistant steel forging, promotes The tissue of wear-resistant ball changes, and makes the intensity of wear-resistant ball obtain beyond thought significantly improving, hardness up to 72HRC, and Impact strength is up to 33J/cm2。
A kind of alterant for wear-resistant steel forging that the present invention proposes, its component includes by weight percentage: V:3～6%, Si:5～8%, Ca:1～2%, Cr:3～6%, Sc:1～2%, Sr:7～10%, Nb:2～5%, Mo:1～3%, Ce:1～ 3%, Y:2～5%, La:2～3%, N:3～5%, surplus is Fe.
Preferably, Y element, Ce element, the content of La element meet following relation: 100 × nY=100 × (nCe+nLa)× 0.3+2, wherein nY、nCe、nLaRepresent Y element, Ce element, La element shared percentage by weight in the component of alterant respectively.
Preferably, Sr element, Nb element, Y element, Ce element, the content of La element meet following relation: 100 × nSr= 100×(nNb+nY+nCe+nLa) × 0.2+6, wherein nY、nCe、nLaRepresent that Y element, Ce element, La element are at alterant respectively Shared percentage by weight in component.
Preferably, V element, Si element, the weight ratio of Cr element are 3.5～5.5:6～7:4～5.
Preferably, Cr element, Sc element, Sr element, Nb element, the weight ratio of Mo element are 4～5:1.2～1.8:7.5 ～9.5:3～4:1.5～2.5.
Preferably, its component includes by weight percentage: V:3.5～5.5%, Si:6～7%, Ca:1.5～1.8%, Cr:4～5%, Sc:1.2～1.8%, Sr:7.5～9.5%, Nb:3～4%, Mo:1.5～2.5%, Ce:1.5～2.5%, Y:3～4%, La:2.4～2.6%, N:3.5～4.5%, surplus is Fe.
Use the organizational structure of wear-resistant ball that the present invention processes compared with wear-resistant ball of the prior art, primary austenite by Common equiaxed dendrite thick, non-is changed into isometry network architecture dendrite, and dendrite is the most tiny, number substantially increases Many；Graphite is few by number, thick, straight, wedge angle is sharply changed into number showed increased, tiny, bending, sharp corner passivation；Eutectic Group is few by number, size big change is that significantly number is many, size is the least for number.The transformation of tissue makes the intensity of wear-resistant ball obtain Beyond thought significantly improving, hardness is up to 72HRC, and impact strength is up to 33J/cm2。
