Kev Cai Casting: Tus yuam sij rau kev qhib qhov siab tshaj plaws ntawm cov khoom siv crusher hnav
Hauv cov kev lag luam mining, quarrying, thiab aggregate processing niaj hnub no, cov crushers ua haujlwm nyob rau hauv cov xwm txheej nyuaj thiab hloov pauv. Txij li cov granite ua haujlwm siab-abrasive mus rau cov hlau ore crushing siab, txhua daim ntawv thov muaj cov teeb meem tshwj xeeb uas cuam tshuam ncaj qha rau lub neej ua haujlwm thiab kev ua tau zoo ntawm cov khoom siv hnav tseem ceeb. Tau ntau xyoo, ntau tus neeg ua haujlwm tau cia siab rau cov khoom siv hnav uas tsis muaj txee, ib qho loj-haum-txhua tus, tsuas yog ntsib cov teeb meem rov tshwm sim ntawm kev ua tsis tiav ua ntej, lub sijhawm tsis tau npaj tseg, thiab kev nce nqi tag nrho ntawm kev muaj (TCO). Raws li kev lag luam xav tau kev ua haujlwm zoo thiab kev txhim kho tus nqi loj hlob, kev tsim kho tshwj xeeb tau hloov pauv los ntawm kev muab khoom tshwj xeeb mus rau qhov tseem ceeb rau kev ua haujlwm ntawm cov crusher. Tsab xov xwm no tshawb nrhiav qhov tseem ceeb ntawm kev tsim kho tshwj xeeb rau cov khoom siv hnav crusher, nws cov qhov loj me tseem ceeb, thiab cov txiaj ntsig ntsuas tau uas nws muab rau cov neeg ua haujlwm thoob ntiaj teb.
Cov Kev Txwv Tsis Pub Siv Cov Khoom Siv Uas Tau Txheem
Cov khoom siv uas siv tau raws li tus qauv, suav nrog cov phaj puab tsaig, cov ntaub thaiv cone, cov pas nrig cua tshuab, thiab cov phaj grate, yog tsim los kom haum rau ntau hom crusher qauv thiab cov ntawv thov dav dav. Txawm li cas los xij, qhov kev tsim qauv thoob ntiaj teb no los nrog kev hloov pauv tsis zam. Piv txwv li, ib lub phaj puab tsaig hlau manganese txheem yog tsim rau qhov nruab nrab ntawm kev cuam tshuam thiab kev sib txhuam, tab sis yuav ua haujlwm tsis zoo hauv qhov chaw sib txhuam siab heev nrog kev cuam tshuam tsawg, qhov twg nws cov khoom ua haujlwm-tawv tsis tuaj yeem ua haujlwm tag nrho. Ib yam li ntawd, qhov kev tsim qauv ntawm cov kab cone liner dav dav yuav tsis sib haum nrog tus neeg teb xov tooj qhov loj me pub, qhov nyuaj ntawm cov khoom siv, lossis qhov tso zis xav tau, ua rau kev hnav tsis sib xws, txo qis throughput, thiab kev siv hluav taws xob ntau dua. Cov ntaub ntawv kev lag luam qhia tau hais tias cov khoom siv uas siv tau raws li tus qauv feem ntau tsuas yog xa 40-60% ntawm lawv lub neej ua haujlwm thaum siv rau hauv cov xwm txheej tsis zoo, yuam cov neeg teb xov tooj kom dais cov nqi hloov pauv tsis tsim nyog thiab lub sijhawm tsis ua haujlwm.
Qhov Loj Tseem Ceeb ntawm Kev Tsim Kho Tshwj Xeeb
Kev ua kom zoo tshaj plaws ntawm kev casting tsis yog tsuas yog hais txog kev hloov kho qhov loj ntawm ib feem xwb, tab sis yog ib txoj hauv kev uas ua kom txhua yam ntawm cov khoom siv haum rau tus neeg teb xov tooj txoj haujlwm tshwj xeeb. Rau cov chaw tsim khoom tshaj lij, qhov kev hloov kho no tsom mus rau peb lub hauv paus tseem ceeb uas tsis tuaj yeem sib tham tau:
Ua ntej, kev hloov kho cov khoom siv. Kev ua tau zoo ntawm ib qho khoom siv hnav pib nrog nws cov khoom siv hlau. Tsis zoo li cov khoom siv txheem uas siv cov khoom siv ruaj khov, ib qho loj me-haum-txhua yam, kev casting tshwj xeeb tso cai rau kev hloov kho kom raug ntawm cov khoom sib xyaw kom phim qhov sib npaug ntawm kev cuam tshuam thiab kev sib txhuam hauv daim ntawv thov. Rau kev sib tsoo thawj zaug uas muaj kev cuam tshuam siab, cov hlau manganese siab hloov kho (xws li Mn18Cr2) nrog cov khoom ua haujlwm tawv dua yog qhov zoo tagnrho, vim nws tsim cov nplaim hnav ruaj khov thaum tseem khaws cov tawv sab hauv kom tiv taus kev tawg. Rau kev sib tsoo theem ob thiab theem peb uas muaj kev cuam tshuam tsawg, kev sib txhuam siab, cov hlau cam khwb cia dawb siab chromium muab kev tiv thaiv kev sib txhuam zoo dua, thaum cov ntaub ntawv sib xyaw bimetallic thiab TiC-reinforced inserts muaj rau cov xwm txheej ua haujlwm hnyav, ntev lub neej kev pabcuam txog li 80% piv rau cov ntaub ntawv txheem.
Qhov thib ob, kev tsim qauv zoo tshaj plaws. Lub geometry ntawm ib qho khoom hnav cuam tshuam ncaj qha rau kev ua haujlwm zoo ntawm kev sib tsoo thiab kev hnav sib xws. Kev tsim kho tshwj xeeb ua rau muaj kev tsim qauv ntawm cov hniav profile rau lub puab tsaig phaj, cov duab kab noj hniav rau cov cone liners, thiab cov qauv qhov rau cov phaj grate, txhua yam sib haum nrog tus neeg teb xov tooj cov yam ntxwv pub khoom noj, cov kev xav tau ntawm lub peev xwm tsim khoom, thiab qhov sib txawv ntawm cov zis tawm. Piv txwv li, kev tsim qauv phaj puab tsaig hniav tob tuaj yeem hloov kho rau cov khoom noj loj kom txhim kho lub zog tom thiab txo qhov slippage, thaum lub cone liner qhov chaw zoo tshaj plaws tuaj yeem ua kom muaj kev faib tawm ntawm cov khoom me me thiab txo qhov hnav hauv zos, ua kom lub neej siv tau ntawm tag nrho cov khoom.
Qhov thib peb, kev txhim kho cov txheej txheem casting. Txawm tias cov khoom siv thiab kev tsim qauv zoo tshaj plaws yuav ua tsis tau raws li qhov xav tau yog tsis muaj cov txheej txheem casting precision. Kev casting tshwj xeeb suav nrog cov txheej txheem kho cua sov tshwj xeeb, xws li kev ua kom cov hlau manganese tawv thiab cov voj voog quenching-tempering rau cov hlau chromium siab, kom ntseeg tau tias cov khoom siv ua tiav nws qhov nyuaj thiab tawv. Cov thev naus laus zis casting siab heev, suav nrog kev casting ua npuas dej poob, kuj tseem siv los tshem tawm cov qhov tsis zoo sab hauv, xyuas kom meej qhov tseeb ntawm qhov loj me, thiab xa cov khoom zoo sib xws thoob plaws txhua pawg ntau lawm.
Cov txiaj ntsig ntawm kev ua haujlwm thiab kev nyiaj txiag uas ntsuas tau
Qhov txiaj ntsig ntawm kev ua cov khoom siv kho kom haum raws li qhov xav tau yog pom tseeb hauv kev txhim kho kom pom tseeb thiab muaj txiaj ntsig zoo rau cov neeg ua haujlwm. Cov kev tshawb fawb hauv kev lag luam qhia tau tias cov khoom siv kho kom haum raws li qhov xav tau ua rau lub neej ua haujlwm ntev dua 30-60% piv rau cov khoom siv txheem, txo qhov zaus hloov pauv thiab cov nqi zog ua haujlwm. Lub neej ua haujlwm ntev no txiav lub sijhawm tsis tau npaj tseg los ntawm 25-40%, ua rau cov neeg ua haujlwm ua tau zoo tshaj plaws thiab ua tiav cov hom phiaj tsim khoom nruj. Qhov tseem ceeb tshaj plaws, kev ua cov khoom siv kho kom haum raws li qhov xav tau txo cov nqi tag nrho ntawm kev muaj los ntawm 20-40% thoob plaws lub neej ntawm cov khoom, txawm tias muaj tus nqi yuav khoom siab dua me ntsis. Rau lub chaw ua pob zeb nruab nrab uas ua tiav 500,000 tons ntawm granite txhua xyoo, qhov no txhais tau tias txuag tau nyiaj txhua xyoo ntau dua $ 120,000, nrog rau kev txhim kho tseem ceeb hauv kev ua haujlwm zoo.
Xaus lus
Raws li kev lag luam thoob ntiaj teb kev sib tsoo txuas ntxiv mus, qhov kev thov rau cov kev daws teeb meem hnav uas ua raws li tus qauv thiab ua tau zoo yuav tsuas yog loj hlob xwb. Kev tsim kho tshwj xeeb daws cov teeb meem tseem ceeb ntawm cov khoom siv txheem, sib phim txhua yam ntawm cov khoom hnav nrog tus neeg teb xov tooj cov xwm txheej ua haujlwm tshwj xeeb kom qhib qhov kev ua tau zoo tshaj plaws thiab kev txuag nqi.
Ua ib lub tuam txhab tsim khoom uas tshwj xeeb hauv kev tsim cov khoom siv crusher nrog ntau xyoo ntawm kev paub txog kev tsim khoom, peb ua haujlwm nrog peb cov neeg siv khoom los ua qhov kev ntsuam xyuas qhov xwm txheej ntawm qhov chaw, tsim cov khoom siv thiab cov kev daws teeb meem tsim, thiab xa cov khoom zoo sib xws, ua tau raws li qhov xav tau ntawm kev lag luam.
