Nyob rau hauv mining thiab aggregate ntau lawm, hloov zaus ntawm crusher coj qhov chaw xws lilub puab tsaig phaj, mantles, thiab lub tais linermuaj kev cuam tshuam ncaj qha rau cov nqi khiav lag luam thiab cov khoom siv uptime.
Txawm tias thaum hnav cov khoom yog tsim los ntawm tib qib siab manganese steel, lawv lub neej kev pabcuam tiag tiag tuaj yeem sib txawv. Qhov sib txawv tseem ceeb yog tsis tsuas yog nyob rau hauv lub alloy muaj pes tsawg leeg tab sis nyob rau hauv lubKev kho cua sov txheej txheem, tshwj xeeb tshaj yog covdaws tshav kub kho nrog dej quenching.
1. Vim li cas kev kho cua sov txiav txim siab qhov kev ua tau zoo ntawm Crusher Liners
High manganese steel qib xws liMn18Cr2 thiab Mn22Cr2yog dav siv nyob rau hauv siab - cuam tshuam thiab siab - abrasion crushing daim ntaub ntawv. Nyob rau hauv kev cuam tshuam thiab kev nyuaj siab, kev kho manganese steel tsim kom muaj txheej txheej tawv tawv thaum khaws cov tub ntxhais austenitic tawv, muab kev tiv thaiv zoo rau kev puas tsuaj.
Txawm li cas los xij,raws li - cam khwb cia siab manganese hlau tsis lawm muaj cov khoom no.
Tus Txheej Txheem Tseem Ceeb: Kev Ua Haujlwm Hardening yuav tsum tau ua kom tiav
Qhov tseem ceeb ntawm cov hlau manganese siab -ua hauj lwm hardening yogtsis muaj nyob tom qab casting. Nws yuav tsum tau qhib los ntawm kev tswjtshuaj kho cua sov, feem ntau raug xa mus rau hauv kev lag luam lidej quenching cua sov kho.
Txheej txheem parameter:
- Qhov kub thiab txias:1050-1100 degree
- Lub sijhawm so kom txaus
- Cov dej nrawm nrawm
Tom qab kho kom raug:
- Carbide tes hauj lwm tag nrho yaj mus rau hauv cov hlau matrix
- Ib leeg, ruaj khovaustenitic microstructureyog tsim
Cov qauv no coj raws li "mos tab sis tawv puag":
- Pib hardness nyob ib ncig ntawmHB 200
- Nyob rau hauv kev cuam tshuam thiab compression, nto hardness sai nce mus rauHB 500+
- Lub liner yuav nyuaj dua thaum lub sijhawm ua haujlwm thaum tswj kev toughness sab hauv
Qhov no yog vim li cas vim li cas thiaj zoo - kho manganese steel liners feem ntau piav raws li"qhov ntau lawv ua haujlwm, qhov hnav ntau dua- lawv dhau los."
2. Kev tswj xyuas kev kho cua sov ntawm Duma Machinery
Raws li tus kws tshaj lij crusher hnav qhov chaw tsim khoom,Jiangxi Duma Machinerynruj me ntsis siv atswj cov txheej txheem kev kho cua sovlos xyuas kom meej qhov kev ua tau zoo liner.
Kauj Ruam 1: Digitally tswj cua sov
Crusher liners tau muab tso rau hauv cov khoom siv hluav taws xob kho cua sov thiab maj mam ua kom sov1050-1100 degree.
Precise cua sov curves yog qhov tseem ceeb los tiv thaiv thermal stress cracking, tshwj xeeb tshaj yog rau cov loj castings.
Duma ua haujlwm cov tshuab hluav taws xob siv hluav taws xob nrog lub sijhawm tiag tiag - tswj qhov kub thiab txias, kom ntseeg tau tias cov cua sov tsis sib xws thiab qhov zoo ntawm metallurgical tej yam kev mob.
Kauj Ruam 2: Siab -Tub Soaking rau Microstructural Uniformity
Ntawm qhov kub siab tshaj plaws, cov ntaub pua tsev tau tuav ntev txaus kom ua tiav cov carbide dissolution.
Qhov no yog qhov tseem ceeb rau tuab - ntu ntu.
Qhov tseeb-raws li muaj peev xwm:
Txawmgyratory crusher liner nrog phab ntsa thickness tshaj 200 mmua tau zoo ib yam nyob rau hauv thiab sab nraud microstructures nyob rau hauv Duma tus txheej txheem tswj.
Kauj Ruam 3: Cov dej nrawm nrawm (Lub Sij Hawm Txiav Txim Siab)
Tam sim ntawd tom qab soaking, liab - cov ntaub kub kub tau hloov mus rau hauvloj - muaj peev xwm circulating dej tanks.
- Cooling txoj cai:
High - cov twj tso kua mis ua kom ceev ceev thiab txias txias
Tiv thaiv carbide re- nag lossis daus
Locks nyob rau hauv cov qauv austenitic
- Kev ntsuas kev ua tau zoo:
Deg hardness tom qab ua hauj lwm hardening:Ntau dua lossis sib npaug rau HB 500
Elongation:Ntau dua lossis sib npaug li 40%
Impact toughness txhim kho:20% + piv nrog cov txheej txheem pa
3. Peb Qhov Zoo Tshaj Plaws ntawm Duma High Manganese Steel Liners
1. Superior Impact Resistance
Txawm nyob rau hauv rov cuam tshuam los ntawm cov pob zeb nyuaj xws ligranite thiab basalt, liners tiv thaiv kev tawg thiab tawg, txo qis kev poob qis.
2. Lub neej ua haujlwm ntev dua
Cov ntawv thov hauv teb qhia tias cov ntaub ntawv kho nrog Duma cov txheej txheem dej quenching feem ntau ua tiav20-40% lub neej ua haujlwm ntevtshaj li cov ntaub ntawv uas tsim los nrog kev kho cua sov.
3. Kev txhim kho zoo heev raug
Los ntawm kev ua kom zoo rau lub qhov cub thauj khoom thiab quenching orientation, cua sov-kev kho-induced deformation yog tsawg.
Qhov no xyuas kom meej haum nrog loj crusher hom xws liMetso thiab Sandvik, txo cov teeb meem kev teeb tsa thiab kev txhawb nqa kev sib txuas.
4. Yuav ua li cas txheeb xyuas qhov siab -Quality Crusher Wear Parts
Rau cov kws tshaj lij cov neeg yuav khoom thiab cov kws kho tsheb, cov kev kuaj xyuas hauv qab no tau pom zoo:
Paub meej tias tag nrho cov qauv austenitic thiab carbide tswj raws liASTM A128qauv.
- Hauv -cov chaw kho cua sov hauv tsev
Tsuas yog cov tuam txhab lag luam uas muaj lub tank loj loj thiab cov tshuab hluav taws xob siv hluav taws xob tuaj yeem ua kom cov khoom sib xws - mus rau - cov khoom sib xws.
- Tsis yog -kev kuaj kev puas tsuaj (NDT)
Xyuas kom tseeb tias liners undergoUT lossis MT tshuaj xyuastxhawm rau tshem tawm cov kev pheej hmoo tawg sab hauv.
Xaus
Kev ua tau zoo ntawm siab manganese steel crusher hnav qhov chaw nyob ntawm qhov tsis yog ntawm cov tshuaj muaj pes tsawg leeg, tab sis raumeej thiab tswj kev kho cua sov.
Los ntawm kev sib txuas cov kev xaiv zoo tshaj plaws alloy nrog kev tswj xyuas nruj heev kev kho cua sov thiab dej quenching,Duma Machinery xa cov crusher liner nrog cov ntaub ntawv pov thawj toughness, ntev hnav lub neej, thiab txhim khu kev qha qhov tseeb.
Kev xaiv Duma txhais tau hais tias xaiv cov khoom hnav uas tau lees paub los ntawm kev tshawb fawb metallurgical thiab tiag -lub ntiaj teb crushing tej yam kev mob.
