High Manganese Steel, tseem hu uaAustenitic Manganese hlaulos yogHadfield Steel, yog lub siab - alloy steel dav lees paub rau nws cov khoom siv tshuab tshwj xeeb. Nws yog ib qho ntawm cov khoom siv feem ntau siv nyob rau hauvCrusher Hnav Partssector vim nws superiorabrasion tsis kam.
Tus nqi tseem ceeb ntawm siab manganese steel castings siv los ntawmDuma Machinerynyob rau hauv lawv lub peev xwm los mus ua hauj lwm Hardening thaum raug cuam tshuam thiab siab ceev. Qhov no tsim ib qho nyuaj heev, hnav- txheej txheej tiv thaiv uas tiv thaiv cov khoom siv sab hauv.
Key Alloy Composition thiab Standards
Kev ua haujlwm ntawm cov hlau manganese siab feem ntau yog tswj hwm los ntawm nws cov ntsiab lus carbon (C) thiab manganese (Mn). Raws li cov qauv kev lag luam (xws li ASTM A128), cov tshuaj lom neeg muaj pes tsawg leeg yog raws li hauv qab no:
| Element | Qhov hnyav% | Muaj nuj nqi |
| Mn | 11.0% ~ 14.0% |
Stabilizes tus qauv austenitic thiab induces ua hauj lwm hardening raws li kev cuam tshuam. |
| C | 0.9% ~ 1.3% |
Muab siab zog thiab hardness, ua hauj lwm nyob rau hauv synergy nrog manganese kom ua tau ib tug austenite -carbide equilibrium. |
| Si | Tsawg dua lossis sib npaug li 1.0% |
Txhim kho castability thiab lub zog. |
| P & S | Tsawg dua lossis sib npaug li 0.07% |
Tswj nruj impurities, raws li cov ntsiab lus siab txo qhov cuam tshuam toughness. |
> Kev ntseeg tau qhov peev txheej:Cov kev sib xyaw ua ke no ua raws li cov qauv kev lees paub thoob ntiaj teb cov khoom siv (Piv txwv li, ASTM A128 Standard Specification rau Steel Castings, Austenitic Manganese), tsim kev lag luam benchmark rau kev ntsuam xyuas siab manganese steel casting zoo.
3. Tshwj xeeb zoo thiab hnav tsis kam tshuab
High manganese steel yog qhov kev xaiv zoo tshaj plaws rau crusher hnav qhov chaw tsis yog vim nws qhov pib hardness, tab sis vim nws qhov tsis sib xws.ua hauj lwm - hardeningmuaj peev xwm.
① Ua haujlwm hnyav
* Mechanism:Thaum raug mob hnyavcuam tshuam, compression, los yogsiab -stress abrasion, txheej txheej ntawm steel undergoes saimartensitic kev hloov pauvthiabntxaib deformation.
* Qhov tshwm sim:Cov khoom siv nrog qhov pib Brinell Hardness (BHN) ntawm kwv yees li 200 tuaj yeem pom nws qhov tawv tawv sai sai rau 500-600 BHN, tsim kom muajmuaj zog heev, hnav- tiv taus txheej txheej.
② Siab Toughness
Hauv qab lub hardened nto, cov khoom sivcore khaws tshwj xeeb toughness. Qhov no enables siab manganese hlau qhov chawnqus tau ntau lub zogtsis muaj kev puas tsuaj thaum raug mob hnyav (piv txwv li,tawg tsis kam).
Cov yam ntxwv no yog qhov tseem ceeb rau siab - cuam tshuam crusher Cheebtsam xws li lub puab tsaig phaj, rauj, thiab mantles.
③ Cov txiaj ntsig nyiaj txiag
Los ntawm kev ncua kev pab cuam lub neej ntawm cov khoom, siab manganese steel castings zootxo cov khoom siv downtimethiabtu ncua zaus, txo qis tag nrho cov nqi ua haujlwm rau cov neeg siv khoom lag luam.
4. Kev Tswj Xyuas Zoo thiab Daim Ntawv Thov ntawmDuma Machinery
Duma Machinerynruj me ntsis raws li cov txheej txheem hauv qab no hauv kev tsim cov khoom siab manganese steel castings kom ntseeg tau tias cov khoom ua tau zoo:
* Kev kho cua sov:Cov khoom siv yuav tsum tau ua kom tiavkev kho mobthiabdej quenchingtshem tawm carbides precipitated thaum lub sij hawm casting, kom ntseeg tau ib tug ntshiab austenitic qauv thiab siab tshaj plaws tej yam toughness.
* Daim ntawv thov:High manganese steel castings yog qhov kev xaiv zoo tshaj plaws rau kev tsim khoomLub puab tsaig Crushers rau lub puab tsaig, Mantles thiab Concaves rau Cone Crushers, thiab paub tseebRauj taub hau rau rauj Crushers.
5. Cov lus xaus
High manganese steel castings yog qhov tseem ceeb rau kev daws cov teeb meem ntawmsiab abrasion thiab hnyav cuam tshuamhauv kev lag luam mining, metallurgy, thiab kev tsim kho, ua tsaug rau lawv cov haujlwm tshwj xeeb - muaj peev xwm hardening thiab superior cuam tshuam. XaivCrusher Hnav Partslos ntawm manufacturers nyiamDuma Machinery, uas nruj me ntsis ua raws li cov qauv thoob ntiaj teb thiab cov txheej txheem siab heev, yog qhov tseem ceeb los ua kom cov khoom siv tau zoo thiab ruaj khov.
