I-HPGR Wear Protection Solutions

Njengoba kudingeka ama-HPGR ukuze asingathe izingcindezi eziphakeme kakhulu nezinto ezihuquzelayo, ukuguga kuyizindleko ezinkulu zokusebenza kanye nesici ekusebenzeni kahle nokutholakala kwazo. Ukuvikela ukugqoka okusebenzayo kubalulekile. Ake sihlaziye izixazululo zokuvikela ukugqokwa kwamaroli okugaya umfutho ophezulu (i-HPGR).

I-HPGR Wear Protection Solutions

1. Izinto Ezisetshenziswayo Zokusonga Nokuklama:

I-Base Material: Umzimba we-core roll ngokuvamile wenziwa ngensimbi ekhandiwe enamandla amakhulu noma ngezinye izikhathi ama-alloys ensimbi ayisipesheli ukuze amelane nezingcindezi ezinkulu zokusebenza.

I-Wear Surface Design: Izindlela ezivame kakhulu zokugqokwa kwangempela yilezi:

Ama-Solid Rolls (Angajwayelekile Kancane Kumayunithi Amakhulu): Wonke umzimba we-roll ungase wenziwe nge-alloy engagugi, kodwa lokhu akuvamile kuma-HPGR amakhulu, esimanje ngenxa yezindleko nezinselele zokukhiqiza.

Amaroli Ahlukanisiwe: Indawo engaphezulu yenziwe ngabalingisi abaningi noma amasegimenti enziwe ngomgunyathi aboshwe noma afakwe ukhiye emzimbeni weroll. Lokhu kuvumela ukushintshwa kalula kwezigaba ezigugile.

Amathayi/Imikhono: Ungqimba oluguquguqukayo lwangaphandle ("isondo" noma "umkhono") luyashwabana noma luboshelwe ku-core roll shaft/umzimba. Lona umklamo ovame kakhulu futhi osebenzayo, ovumela ukushintshwa kalula kwendawo egugile ngaphandle kokushintsha wonke umzimba we-roll.

2. Ubuchwepheshe Bokuvikela Ubuso (Busetshenziswa Emathayini/Imikhono noma Izingxenye):

Kulapho kulele khona amasu ahluke kakhulu okuvikela ukugqokwa:

I-Welded Hardfacing Overlays:

Inqubo: Ukusebenzisa izendlalelo zezinto zokushisela eziqine kakhulu, ezingagugi endaweni yomqulu. Izindlela ezijwayelekile zifaka i-Summerged Arc Welding (SAW) noma i-Open Arc Welding (i-Flux-Cored Arc Welding - FCAW).

Izinto: Ngokuvamile ama-alloys aphezulu e-chromium carbide (CrC), ama-carbides ayinkimbinkimbi, noma ngezinye izikhathi izinhlanganisela ze-tungsten carbide (WC) ngaphakathi kwe-matrix.

Izici: Idala indawo eqinile, ekwazi ukumelana nemihuzuko. Kungenziwa ezendlalelo eziningi. Ngokuvamile isetshenziswa kumaphethini athile (isb., i-chevron, i-waffle) ukusiza ukukhishwa kwezinto kanye nokuthutha. Ingashicilelwa kabusha/ilungiswe izikhathi eziningi, kungaba in-situ noma endaweni yokusebenzela.

Izinzuzo: Isixazululo sokuqala esingabizi kakhulu, ubuchwepheshe obulungisekayo, obuzinze kahle.

Ububi: Impilo yokugqoka ingashintshashintsha kuye ngensimbi; ikwazi ukuchitheka kalula noma ukuqhekeka ngaphansi komthelela omkhulu kakhulu noma ukuhluka kwengcindezi; ikhwalithi ye-weld ibalulekile.

I-Tungsten Carbide (WC) Studs / Insert:

Inqubo: Kushumeka izikhonkwane ze-tungsten carbide eziyisilinda noma ezimise ngokukhethekile emigodini ebhojwe ngaphambili endaweni yomqulu (isondo/ingxenye). Izikhonkwane ziyaziqhenya ngendawo ephansi.

Indlela: Izikhonkwane zithatha umhuzuko oqondile. Okubalulekile, into ecolekile ihlangana phakathi kwama-studs, yakhe isendlalelo "esizenzakalelayo" noma "sokuzivikela ngokuzenzakalela" esivikela into engaphezulu kwe-base roll. Ukugqokwa kwenzeka ikakhulukazi ezikolweni ze-WC nalolu ungqimba lwempahla oluvalelekile.

Izinto: Izikhonkwane zekhwalithi ephezulu ze-Tungsten Carbide Cobalt (WC-Co).

Izinzuzo: Impilo yokugqoka enhle kakhulu, evamise ukuba yinde ngokuphawulekayo kune-hardfacing kuma-abrasive kakhulu; igcina iphrofayili engaphezulu engaguquki njengoba igqoka; ikhuthaza ukusebenza okuzinzile ngenxa yesendlalelo esizenzakalelayo.

Ububi: Izindleko zokuqala eziphakeme; idinga ukukhiqizwa okukhethekile; engalungiswa kalula kalula endaweni (imvamisa idinga ukushintshwa kwamasondo); okungaba khona ukulahleka kwe-stud uma kungakhiwanga/kufakwe ngendlela efanele noma uma i-tramp metal idala umonakalo.

Amasegimenti we-Cast Wear / Tiles:

Inqubo: Ukubhawulisa noma ukunamathisela amabhulokhi noma amathayela angakwazi ukumelana nokugqoka okuphezulu (ngokuvamile I-Iron Emhlophe Ye-Chrome - i-HCWI, noma amanye ama-alloys akhethekile) emzimbeni wokugoqa noma esakhiweni sethaya lesisekelo.

Izici: Kuyafana ngokomthetho namaroli ahlukene kodwa kwesinye isikhathi angasetshenziswa njengamathayela amancane, amaningi kakhulu.

Izinzuzo: Ivumela ukushintshwa kwezingxenye zokugqoka okuphezulu; ingasebenzisa izinto zokuphonswa eziqinile kakhulu.

I-Cons: Amakhanda we-Bolt / amaphuzu okunamathiselwe angaba amaphuzu okugqoka; kungenzeka ukuthi amathayili aqhekeke noma axege; amalunga amaningi kwesinye isikhathi angathinta ukukhishwa kwempahla uma kuqhathaniswa nendawo eqhubekayo.

Izixazululo Ezihlanganisiwe: Kwesinye isikhathi kusetshenziswa izinhlanganisela, isb., ukufaka okuqinile phakathi kwemigqa yezigxobo, noma izixazululo ezihlukene ezingxenyeni ezihlukene zobuso be-roll.

3. Ukuvikelwa Konqenqema (Amapuleti Ehlathi):

Izinhlangothi zamaroli (amaphethelo) nazo zibhekana nokuguga okuphawulekayo kusuka kungcindezi yezinto ezibonakalayo kanye nokuhuzuka.

Isixazululo: Amapuleti okugqoka omhlatshelo, aziwa ngokuthi "amapuleti ezihlathini" noma "amabhulokhi onqenqemeni," afakwa eduze neziphetho zomqulu. Ngokuvamile lezi zenziwa ngensimbi enobuso obuqinile, izinsimbi zensimbi ezine-chrome, noma ngezinye izikhathi izitsha zobumba. Zenzelwe ukuthi zishintshwe ngezikhathi ezithile. Idizayini efanele yepuleti lesihlathi nokugcinwa kwayo kubalulekile ukuze kuvinjwe ukuguga okweqile konqenqema endaweni eyinhloko.

4. Ukucatshangelwa kokuSebenza:

Ukulawula Okuphakelayo: Ukuphakelwa okungaguquki kubalulekile. Ukusabalalisa okuphakelayo okungalingani kuholela ekugqokeni okungalingani.

Ukulawula Ukucindezela: Ukusebenza ebangeni elifanele lengcindezi kulinganisa ibhalansi, ukusebenza kahle kokugaya, nezinga lokuguga. Ukucindezela okwedlulele kusheshisa ukuguga.

Ukususwa kwe-Tramp Metal: Omazibuthe nezitholi zensimbi ezikhuphuka nomfula zibalulekile ukuze kuvinjwe umonakalo oyinhlekelele ezindaweni eziqengqelekayo.

Okuqukethwe Komswakama: Kungathinta ukugeleza kwezinto kanye nokuhuga.

Isivinini Sokugoqa: Isivinini esiphezulu ngokuvamile sinyusa izinga lokuguga.

5. Ukuqapha Nokunakekela:

I-Wear Monitoring: Isilinganiso esivamile sobubanzi be-roll nephrofayela (kusetshenziswa izikena ze-laser noma izikali zephrofayela) kubalulekile ukuze ulandelele amanani okuguga nokubikezela amashejuli okushintshwa.

Ukuqapha Isimo: Ukudlidliza, izinga lokushisa, nokuqapha kwe-acoustic kungasiza ekutholeni izinkinga ezifana nokuthwala izinkinga noma ukusebenza okungalingani okungase kubhebhethekise ukuguga.

Ukuhlola: Ukuhlolwa okuvamile okubonwayo kokuqhekeka, ama-spalling, ama-stud alahlekile, noma ukulimala kwepuleti lezihlathi.

Ukunakekela Okubikezelwayo: Ukusebenzisa idatha yokuguga nomlando wokusebenza ukuze uhlele ukuvela kabusha (i-hardfacing) noma ukushintshwa kwamasondo/ingxenye ngokuqhubekayo, kuncishiswe isikhathi sokuphumula.

I-Roll Grinding: Ukugaya ama-roll ezindawo ngezikhathi ezithile (ikakhulukazi ezinobuso obuqinile) kungabuyisela iphrofayili oyifunayo futhi kususe ukungahambi kahle kwendawo, nakuba lokhu kususa izinto ezigugayo ezisebenzisekayo.

Izinto zokukhetha:

Isixazululo esingcono kakhulu sokuvikela ukugqoka sincike kakhulu kulokhu:

Izici ze-Ore: Ukuqina (okubucayi!), Ukuqina, usayizi wezinhlayiyana, i-mineralogy.

Amapharamitha Okusebenza: Ingcindezi, isivinini, okuhlosiwe kokuphumayo.

Isabelomali: Izindleko zokuqala uma kuqhathaniswa nezindleko zesikhathi eside zobunikazi (impilo yokugqoka, imvamisa yokushintsha, isikhathi sokuphumula).

Isu Lokulungisa: Amakhono okulungisa endaweni uma kuqhathaniswa nokuthandwayo kokushintsha indawo yokusebenzela.

Izincomo ze-OEM: Abakhiqizi banolwazi olunzulu ngezinhlelo zokusebenza ezahlukahlukene.

Kafushane, ukuvikelwa kokugqokwa kwe-HPGR kuhilela inhlanganisela yomklamo oqinile, ubuchwepheshe obuthuthukisiwe bokuvikela indawo (ikakhulukazi i-hardfacing noma izikhonkwane ze-WC), ukuvikela okusebenzayo konqenqemeni, izinqubo zokusebenza ezithuthukisiwe, nokuqapha nokunakekela ngenkuthalo. Inketho incike kuhlelo lokusebenza, okuhloswe ngayo ukulingana okungcono kakhulu kwempilo yokugqoka, ukusebenza, kanye nezindleko.
