Ukwelashwa kwe-Uneven Wear Surface ye-Carbide Stud Roller

Ngokomshini wokuguga we-roller surface ye-high pressure roller mill, indawo eyi-carbide stud roller surface iye yathuthukiswa eminyakeni yamuva nje. Isilinda esifakwe i-tungsten-cobalt cemented carbide sishunyekwe emzimbeni we-roller sleeve ukuze sakhe isigaba esiqinile esinobulukhuni obufika ku-HRC67. Igebe phakathi kwe-stud futhi ligcwaliswa yizinhlayiya ezinhle kumpahla, ngaleyo ndlela yakhe i-liner ebonakalayo ukuvikela umzali womkhono we-roller. I-Stud roller surface inezinzuzo zokungagugi kahle, impilo ende yesevisi yesikhathi esisodwa, umsebenzi omncane wokulungisa nsuku zonke, futhi isetshenziswe ezimbonini eziningi.

Izizathu zokugqoka okungalingani kwe-roller surface:

Ngenxa yomphumela onqenqemeni we-high pressure roller mill, ingcindezi ye-extrusion phakathi kwe-roller inkulu kunaleyo emikhawulweni yomibili lapho impahla incinywa. Ngokuhamba kwesikhathi, ukuguga phakathi nendawo ye-roll kuba kubi kakhulu kunalokho kuzo zombili iziphetho (isithombe 1). Esigabeni sakamuva sokuguga, igebe phakathi kwama-roller amabili likhulu kakhulu ukwenza ungqimba lwezinto ezibonakalayo, futhi umphumela wokukhipha umshini wokugaya umfutho ophakeme uba mubi kakhulu, futhi igebe eliphakathi lingancishiswa kuphela ngokulungisa igebe lokuqala le-roller. ama-roller amabili. Ngenxa yokuguga okuncane emikhawulweni yomibili, ubuso bokugcina bamarola amabili buzoshayisana uma bulungiswa ngokwezinga elithile, futhi izimo zokwakheka kwesendlalelo sezinto ezimaphakathi azikafinyelelwa, ngaleyo ndlela kuthinte ikhwalithi yokugaya i-roller enomfutho ophezulu. ukuzinza kwemikhiqizo kanye nemishini.

Indawo yerola evundlile yendabuko ingalungisa indawo engaphezulu yerola ukuze ihlangabezane nezidingo zokukhiqiza. I-Stud roller surface iwubude obuthile be-cylindrical cemented carbide stud eshumekwe embotsheni eyi-cylindrical yezinto eziyisisekelo ze-roller surface ukuhlangabezana nezidingo zamandla nobulukhuni bomkhono we-roller, kodwa impahla ye-matrix yomkhono we-roller ibuthakathaka ekusebenzeni kokushisela. , kanye ne-tungsten cobalt cemented carbide esetshenziswa i-stud ayinakho ukusebenza okungaphezulu, ngakho-ke indawo ye-stud roller idinga ukuxazulula inkinga yokulungisa ukuguga okungalingani ngemva kokugqoka kwe-roller surface.

Izimbangela zokuguga okungalingani kwe-roll surface zifaka ukusebenza okungalungile, ukuhlukaniswa kwezinto ezibonakalayo komgqomo wesisindo sokugeleza njalo njalo. Abanye abasebenzisi balungisa inani elidlulayo le-high-pressure roller mill ngokulungisa ukuvuleka kwesango lebha yamanuwali elibekwe ngaphansi kwethangi lokugeleza elizinzile. Uma kuphela isango lebha yezandla phakathi livuliwe, izinto eziningi zidlula phakathi kwe-roller, futhi izinto ezincane kuphela ezidlula emikhawulweni emibili, okuholela ekugqokeni okungalingani kwe-roller. Ukuhlukaniswa kwezinto ezibonakalayo kubangelwa ikakhulukazi ukusethwa okungalungile kwepayipi lenqubo, okuholela ekuhlanganiseni okunganele kwezithako ezintsha kanye nezinto ezijikelezayo emgqonyeni wokugeleza ozinzile.

Indlela yokwelapha:

Kunezinkulungwane zezikhonkwane ze-tungsten-cobalt ze-carbide ezinosimende ezisetshenziswa ezigayweni ezinkulu ze-high-pressure roller, ezingalungiswa ngokusebenza kabi, futhi abukho ubuchwepheshe bokwelapha obuvuthiwe nobuthembekile ekhaya naphesheya. Uma ukusebenza kahle komsebenzi we-high pressure roller mill kubuyiselwa ngokufaka esikhundleni somkhono we-stud roller, akubizi nje kuphela, kodwa futhi ukuchithwa komkhono omdala we-roller kuzoholela ekulahlekeni kwezinsiza. Ngemuva kophenyo olugcwele kanye nengxoxo, kunqunywa ukusebenzisa indlela yokugaya ukuze kuxazululwe inkinga yokuguga okungalingani kwe-roller surface, futhi kuthuthukiswe umshini wokugaya we-stud roller surface. Ngenxa yesikhala esilinganiselwe sokusebenza se-high pressure roller mill kanye nobunzima bokuphakamisa, kuyadingeka ukuklama indlela ekhethekile yamandla okugaya, futhi yonke idivayisi kufanele ibe lula futhi ilula ukuyifaka, ukuze kuzuzwe ukugaya endaweni. .

Idivayisi yokugaya i-stud roller surface ikakhulukazi yenziwe idivayisi yokulinganisa yokulinganisa idatha yokuguga yendawo eqengqelekayo, ipuleti lokugaya, indlela yamandla yokushayela ipuleti lokugaya, indlela yokuphakelayo yokudonsa ipuleti lokugaya eduze kwe-roller axis kanye neradial. ukunyakaza kanye nesistimu yokulawula ukulungisa okuzenzakalelayo. Ngokwezici zokugqokwa kwama-stud roller surface roller, izici zokugqokwa zeziphetho ezimbili ze-stud roller surface zincane futhi ukugqokwa okuphakathi kukhulu, ukhiye wokuxazulula inkinga yedivayisi yokugaya i-stud roller surface ukuhlanganisa ama-roller amabili. Ingxenye ephezulu ye-stud iphansi. Ukuze kuthuthukiswe ukusebenza kahle kokugaya, idivayisi yokugaya iklanyelwe ukuze iziphetho ezimbili ze-roller zisebenze ngesikhathi esisodwa futhi ngokuzimela.

Ngenxa yokuqina okuphezulu kwe-stud, i-disc yokugaya evamile inokusebenza okuphansi nokulahlekelwa okukhulu. Ngokuhlolwa kokugaya okuningi okulingisiwe, ukusebenza kahle kokugaya nokusetshenziswa kwezinhlobo ezahlukene zezingcezu zokugaya kuyaqhathaniswa, futhi isakhiwo seshidi lokugaya esifanele, usayizi, uhlobo oluqhumayo, usayizi wezinhlayiyana, ukuqina kanye nohlobo lokuhlanganisa kuyakhethwa. Indlela yokuphakelayo yedivayisi yokugaya i-stud roller ingalungisa ububanzi bokugaya ngesikhathi sangempela ngesistimu yokulawula ukulungisa okuzenzakalelayo ngokuya ngedatha yokuguga yendawo ye-stud roller. Njengamanje, idivayisi yokugaya isetshenziswe ezigayweni eziningi zamarola ezinomfutho ophezulu wokwelapha ngemuva kokugqokwa kwe-pin roller surface.

Isiphetho:

I-Stud roller surface hardness, ukumelana nokugqokwa okuhle, kungakha ulwelwesi oluvikelayo lomkhono we-roller matrix. Kodwa-ke, esikhathini sakamuva sokusetshenziswa, ngenxa yomphumela wonqenqema we-high pressure roller mill kanye nokuhlukaniswa kwezinto ezibonakalayo komgqomo wesisindo ogelezayo, ukugqokwa kwe-roller surface akufani, nezici zokugqoka zokuguga okuncane emikhawulweni yomibili kanye ukuguga okukhulu phakathi kuthinta isivuno kanye nekhwalithi yemikhiqizo yokugaya i-high pressure roller roller mill. Ngokusebenzisa idivayisi yokugaya i-stud roller ukuze ugaye indawo engalingani ye-stud roller esizeni, ukufana nomphumela wokukhipha i-stud roller ungabuyiselwa, impilo yesevisi yendawo ye-stud roller inganwetshwa, kanye nezindleko eziphezulu nokumoshakala kwensiza. okubangelwa ukushintsha komkhono we-roller entsha kungagwenywa, ngaleyo ndlela kuthuthukiswe ukusebenza kahle kokukhiqiza kanye nezinsiza zokulondoloza.
