High manganese steel, paub txog nws txoj haujlwm tshwj xeeb - hardening zog thiab cuam tshuam tsis kam, yog siv dav hauv kev siv mining, kev tsim kho, thiab kev siv tshuab hnyav.
Khoom Specifications:
Lub metallurgical muaj pes tsawg leeg ntawm hwm siab manganese hlau yuav tsum tau raws li qhov yuav tsum tau muaj:
Manganese cov ntsiab lus khaws cia ntawm 11-14% rau kev pom zoo austenitic stability
Cov pa roj carbon ntau tswj ntawm 1.0-1.4% kom ntseeg tau tias muaj kev sib zog ua kom zoo
Kev txwv nruj ntawm impurities (P<0.05%, S<0.04%) to prevent embrittlement
Kev xaiv chromium ntxiv (1.5-2.5%) rau kev txhim kho corrosion kuj
Txoj kev tsim khoom:
Advanced foundry cov txheej txheem kom zoo ib yam:
Hluav taws xob arc rauv melting nrog argon oxygen decarburization
Khoos phis tawj- tswj qhov kub thiab txias (1420-1480 degree)
Tshwj xeeb xuab zeb molding tshuab rau qhov tseeb qhov tseeb
Tam sim ntawd quenching dej tom qab casting los tiv thaiv carbide tsim
Mechanical Property Verification:
Cov txheej txheem kev sim ua tiav ua pov thawj kev ua haujlwm casting:
Tensile zog pov thawj (Ntau dua los yog sib npaug rau 700 MPa yield zog)
Kev ntsuas cuam tshuam ntawm ntau qhov kub thiab txias
Hardness progression analysis ua ntej - thiab post- ua hauj lwm hardening
Kev ntsuam xyuas microstructural rau kev ntsuas qhov loj ntawm austenite
Dimensional Accuracy thiab Surface Quality
High manganese steel castings yuav tsum ua raws li:
TS EN ISO 8062 Cov qauv kev kam rau siab
Qhov yuav tsum tau ua kom tiav (feem ntau 6.3-12.5 μm Ra)
Kev tshuaj xyuas nruj ntawm qhov hnav thiab qhov tseem ceeb ntawm qhov ntev
Quality Assurance thiab Certifications
Reputable foundries tuav:
ISO 9001 Kev Tswj Xyuas Kev Tswj Xyuas Zoo
ASTM A128 ua raws li cov khoom siv
NDT daim ntawv pov thawj rau cov neeg ua haujlwm soj ntsuam
Daim ntawv thov thiab kev ua haujlwm validation
Kev lag luam- kev ntsuas tus qauv validates casting kev ua tau zoo nyob rau hauv tiag - ntiaj teb no tej yam kev mob:
Abrasion kuj kuaj ib ASTM G65
Kev sim teb hauv kev siv mining thiab crushing
Kev tshuaj xyuas microstructural los xyuas kom meej cov qauv austenitic
Rau siab -kev ua tau zoo manganese steel casting kev daws teeb meem uas ua tau raws li cov qauv zoo thoob ntiaj teb, sab laj nrog peb cov kws tshaj lij niaj hnub no.
