Nyob rau hauv lub sij hawm ntev kev lag luam-crushing kev pab cuam, High Manganese Steel Puab tsaig Plate yog cuam tshuam los ntawm ntau yam: cov khoom hardness, pub txoj kev, cov cuab yeej ua hauj lwm tej yam kev mob, ambient humidity thiab installation raug. Ntau yam ntawm cov xwm txheej tshwm sim tsis tu ncua thiab kev ua haujlwm tsis zoo yuav tshwm sim. Cov xwm txheej no ncaj qha cuam tshuam txog kev ua haujlwm ntawm cov khoom siv thiab kev ua haujlwm zoo, thiab ua haujlwm tseem ceeb ntawm cov ntawv xa mus rau kev ntsuam xyuas lub puab tsaig-plate degradation nrog rau kev saib xyuas thiab hloov raws sijhawm. Txhua qhov tshwm sim muaj qhov sib txawv hauv paus thiab cov yam ntxwv pom tau.
Qhov tshwm sim ntawm kev hnav khaub ncaws ntau tshaj plaws yog qhov hnav tsis zoo ntawm lub ntsej muag, ib qho kev niaj hnub siv tsis tau rau txhua lub puab tsaig phaj. Nyob rau hauv tas li crushing, ore cov ntaub ntawv tsis tu ncua ua zawv zawg kev sib txhuam thiab cuam tshuam scouring tawm tsam lub puab tsaig phaj ua hauj lwm lub ntsej muag thiab crushing hniav. Raws li lub sij hawm ua hauj lwm accumulates, protruding crushing hniav maj mam hnav tiaj tus thiab ua hauj lwm-nto thickness txo tusyees. Cov kev hloov me me tshwm sim hauv crushing-chamber ntim thiab lub kaum sab xis occlusal. Nyob rau theem pib, tsuas yog me ntsis tso tawm-qhov loj me tsis sib xws thiab kev tsim khoom nruab nrab-kev ua tau zoo tuaj yeem pom. Thaum lub sij hawm ntev hnav hnyav heev, crushing hniav poob ua hauj lwm zoo. Cov ntaub ntawv tsis tuaj yeem raug nyem thiab sib cais, uas ua rau cov khoom siv tsis tu ncua, cov khoom poob rov qab thiab tawm ntau dhau. Lub sijhawm no yuav tsum tau hloov lub puab tsaig lub phaj. Hom kev hnav no suav tias yog ib qho khoom siv poob thiab tsis muaj kev pheej hmoo ntawm kev puas tsuaj tam sim ntawd.
Qhov thib ob tseem ceeb tshwm sim yog yas deformation thiab nto-phaj indentation, uas yog tshwj xeeb rau high-manganese hlau. High-manganese steel nta qis pib hardness thiab tsis tshua muaj siab toughness. Thaum crushing loj-loj, high-hardness ores, instantaneous squeezing cuam tshuam ua rau me ntsis, irreversible yas deformation rau ntawm qhov chaw, manifested raws li lub zos ua hauj lwm-surface indentation, skewed crushing hniav thiab me ntsis nto-phaj bulging. Qhov no deformation yuav tsis ncaj qha mus khawb lub puab tsaig phaj, tab sis nws distors lub tsim crushing-chamber profile. Qhov tshwm sim yog cov khoom siv tsis sib xws, cov khoom siv hauv zos jamming thiab inconsistent particle loj. Nws tseem txhawb nqa cov cuab yeej ua haujlwm ua haujlwm thiab ua kom nrawm nrawm ntawm cov motors thiab bearings. Kev puas tsuaj loj zuj zus ntxiv qhov tshwm sim ntawm cov khoom siv tsis ua haujlwm.
Corner chipping, thaiv spalling thiab qaug zog tawg yog cov feem ntau txawv txav-kev puas tsuaj hom nyob rau hauv ntau lawm, feem ntau stemming los ntawm non-standard lag luam thiab txawv txav tej yam kev mob. Thaum uas tsis yog-crushable nyuaj txawv teb chaws lub cev xws li hlau blocks, steel tuav los yog steel daim hlau nkag mus rau hauv lub feed kwj, instantaneous impact loads tshaj lub puab tsaig-phaj bearing muaj peev xwm thiab ncaj qha ua rau lub kaum sab xis chipping thiab loj-thaj chaw spalling ntawm cov chaw ua hauj lwm. Tsis tas li ntawd, kev noj zaub mov ntau dhau mus ntev, yuam kev ua haujlwm ntawm cov khoom siv rov ua dua, thiab ntau zaus pib-nres lub voj voog ua rau lub puab tsaig phaj rau kev hloov pauv tsis tu ncua thiab pib ua kom tawv nqaij tawv nqaij tawg. Yog tsis muaj kev soj ntsuam xyuas kom raws sij hawm, cov kab nrib pleb tsis tu ncua nthuav dav nyob rau hauv kev cuam tshuam rov qab thiab txhim kho mus rau hauv cov pob txha tawg uas ua rau lub puab tsaig phaj tsis tuaj yeem siv tsis tau. Tsis tas li ntawd, xoob lub puab tsaig-phaj kho bolts, installation misalignment thiab offset liner daim hlau ua rau cov kev ntxhov siab tsis sib xws thiab kev ntxhov siab hauv zos, ua rau tawg sai sai thiab thaiv kev sib kis.
Sib nrug los ntawm cov xwm txheej uas tau hais los saum toj no, kev hnav khaub ncaws nrawm nrawm tshwm sim hauv qhov chaw hnyav. Nyob rau hauv qhov chaw qhib huab cua nrog dej nag hnyav, los yog thaum cov khoom noj khoom haus muaj cov sediment ntxiv rau cov kua qaub-alkali impurities, lub puab tsaig phaj ua rau lub puab tsaig abrasive hnav thiab cov tshuaj me me. Nws hnav tus nqi nce mus txog ib mus rau ob npaug ntawm tus nqi pom nyob rau hauv qhuav, huv si, thiab groove-shaped hnav nrog rau pitting corrosion pits nkag rau ntawm cov phaj. Lub caij no, qhov qhib qhov nqaim ntau dhau, cov khoom siv ntau dhau hauv cov crushing chamber thiab cov khoom siv tsis zoo lubrication ntxiv ua rau lub zog hauv zos squeezing hnav ntawm lub puab tsaig phaj thiab txo nws txoj kev xav tau lub neej. Kev ua haujlwm tau zoo thiab kev saib xyuas tsis tu ncua yog li kev ntsuas tseem ceeb rau kev txo qis cov khoom tsis zoo ntawm cov khoom degradation.
