Gupfa nikintu cyibanze munganda ya pellet. Kandi ni urufunguzo rwagukora pellet. Dukurikije imibare ituzuye, ikiguzi cyuruganda rwa pellet gipfa gutakaza hejuru ya 25% yikiguzi cyo gufata neza amahugurwa yose. Kuri buri ijanisha ryiyongera kumafaranga, irushanwa ryisoko ryaragabanutseho 0.25%. Urusyo rwa pellet rero ibisobanuro ni ngombwa cyane.
Shanghai Zhengyi (CPSHZY) ni umunyamwugakugaburira urusyoutanga isoko mu Bushinwa. Dutanga impeta ipfa pellet urusyo, urupfu rwa pellet urusyo naibice bya pellet, nka bipfa gupfa, impeta ipfa, pellet urusyo, nibindi bice kumashini ya pellet.
1.Urusyo rwa pellet rupfa ibikoresho
Uruganda rwa pellet rupfa muri rusange rukozwe mubyuma bya karubone, ibyuma byubatswe byubatswe cyangwa ibyuma bidafite ingese binyuze mu guhimba, gutunganya, gucukura umwobo, hamwe nuburyo bwo gutunganya ubushyuhe. Umukoresha arashobora guhitamo ukurikije ruswa yibintu bito. Ibikoresho by'urusyo rwa pellet bipfa bigomba gukorwa mubyuma byubatswe cyangwa ibyuma bidafite ingese.
Ibyuma byubaka karubone, nkibyuma 45, ubukana bwayo bwo kuvura ubushyuhe muri rusange ni 45-50 HRC, ni ibikoresho byo mu rwego rwo hasi bipfa gupfa, kwihanganira kwambara no kurwanya ruswa birakennye, ubu byavanyweho.
Gukoresha ibyuma byubaka, nka 40Cr, 35CrMo, nibindi, hamwe nubushyuhe bwo kuvura ubushyuhe hejuru ya 50HRC hamwe nibikoresho byiza byahujwe. Urupfu rukozwe muri ibi bikoresho rufite imbaraga nyinshi kandi rukarwanya kwambara, ariko ibibi ni uko kurwanya ruswa atari byiza, cyane cyane kugaburira amafi.
Igiciro cyimpeta ipfa, ikozwe mubikoresho, pellet ya marigold, chipi yimbaho, pellet pelles, nibindi, birarenze cyane ibyuma bitagira umwanda. Byombi 20CrMnTi na 20MnCr5 ni ibyuma bitanga karubasi nkeya, byombi birasa, usibye ko icyambere ari ibyuma byabashinwa nicyuma cyubudage. Kubera ko Ti, ibintu byimiti, bidakunze kuboneka mumahanga, 20CrMnTi cyangwa 20CrMn yo mubushinwa ikoreshwa aho gukoresha 20MnCr5 yo mubudage, ntabwo rero iri murwego rwibyuma byubaka. Nyamara, urwego rukomeye rwicyuma rugarukira kubikorwa bya carburizing kugeza ubujyakuzimu bwa mm 1,2, nabyo bikaba akarusho kubiciro biri hasi yicyuma.
Ibikoresho byuma bidafite ibyuma birimo Ubudage butagira umuyonga X46Cr13, Ubushinwa ibyuma bitagira umuyonga 4Cr13, nibindi. mubisanzwe ibiciro biri hejuru kuruta ibyuma bya karubone. Bitewe nubuzima burebure bwibyuma bitagira umuyonga bipfa ibyuma, inshuro zo gusimbuza ni nkeya bityo igiciro kuri toni ni gito.
Mubisanzwe, ibikoresho bipfa kumpeta bipfa gusya ni ibyuma byubatswe byubatswe hamwe nibyuma bidafite ingese.
2.Ikigereranyo cyo kwikuramo urusyo rwa pellet rupfa
i = d / L.
T = L + M.
M ni ubujyakuzimu bw'umwobo wagabanutse
Ikigereranyo cya Compression (i) ni igipimo cya diametre yipfa (d) nuburebure bukomeye (L) bwurupfu.
Ukurikije imiterere yibikoresho fatizo, igipimo ni 8-15, Umukoresha ahitamo igipimo cyo guhunika cyurupfu, kandi agahindura igipimo cyihariye cyo kwikuramo, nko guhitamo igipimo gito cyo kugabanuka gato, gifite akamaro ko kongera umusaruro, kugabanya gukoresha ingufu, gabanya kwambara kwimpeta, ariko kandi ugabanye ubwiza bwibice, nka pellet ntabwo bikomeye bihagije, isura irekuye kandi uburebure buratandukanye, kandi igipimo cyifu ni kinini.
3.Igipimo cyo gufungura impeta kirapfa
Igipimo cyo gufungura urusyo rwa pellet gipfa ni igipimo cyubuso bwose bwumwobo wapfuye nubuso bwuzuye bwurupfu. Muri rusange, uko igipimo cyo gufungura bipfa, niko umusaruro utubutse. Hashingiwe ku kwemeza imbaraga zo gupfa, igipimo cyo gufungura impeta ipfa gishobora kunozwa uko bishoboka.
Kubikoresho bimwe bibisi, hashingiwe ku kigereranyo gikwiye cyo kugabanuka, urusyo rwa pellet rupfa urukuta ruto cyane, ku buryo imbaraga zo gupfa zidahagije, kandi ibintu byo guturika bipfa bizagaragara mu musaruro. Muri iki gihe, umubyimba wimpeta ugomba gupfa ugomba kwiyongera hashingiwe ku kureba niba uburebure bw’umwobo bupfa.
4.Guhuza urusyo rwa pellet bipfa na roller
Nubuhanga bwingenzi cyane kunoza imikorere ya granulation no kongera ubuzima bwurupfu. Igomba kuba ikubiyemo ibintu 4:
- Impeta nshya ipfa hamwe nigitutu gishya, irinde gukoresha birenze urugero.
- Ukurikije imiterere yibikoresho, ubwoko bwimashini ziranga uburyo bwo guhitamo uburyo butandukanye bwumuvuduko wumuvuduko, kugirango ugere kubikorwa byiza byo gukuramo hagati yo gupfa no kuzunguruka.
- Urufunguzo rwo gutandukanya bikwiye ni ihame kandi ihame ni: utagize ingaruka kubushobozi, gerageza kuruhuka.
- Kugenzura umuvuduko wo kugaburira, hindura umwanya muremure kandi mugufi wo kugaburira scraper kugirango ugenzure aho ugaburira, kugabana ibintu.
5.Uruganda rwa pellet rupfa gutunganya inzira
Impeta zipfa zirasabwa cyane mubijyanye no gutunganya no gutunganya ibikoresho, kandi kubyuma bidafite ingese, imyitozo idasanzwe yimbunda nibikoresho byo gutunganya ubushyuhe bwa vacuum birasabwa kugirango habeho impeta nziza. Uburyo bwiza bwo kuzimya ubushyuhe bwo hejuru burashobora kunoza cyane gukomera, gukomera, kurwanya abrasion, imbaraga z'umunaniro no gukomera kwibyuma. Nyamara, ubushobozi bwo kwemeza uburinganire buringaniye kuri buri mwobo upfa bisaba urwego rwo hejuru rwubuhanga bwo gutunganya nuburambe burebure.
6.Urupfu ruri hejuru yurukuta rwimbere rwumwobo
Ubuso bwubuso nabwo ni ikimenyetso cyingenzi cyerekana impeta ipfa. Muri rusange, agaciro gake k'urukuta rw'imbere imbere gukomera bizamura ireme ryiza, bigabanye kwambara kandi byongere ubuzima bwimpeta ipfa, ariko ikiguzi cyo gutunganya impeta kiziyongera.
Umuhengeri w'impeta nawo ugira ingaruka ku kigereranyo cyo kugabanuka no gukora ibice, kimwe no gukora neza. Ku mpeta imwe ipfa kugabanuka, igabanutse agaciro kayo, niko igabanuka ryikwirakwizwa ryibiti cyangwa ibiti, niko gusohora neza, niko ubwiza bwa pellet bwakozwe kandi niko umusaruro wiyongera. Gutunganya impeta nziza yo gupfunyika bishobora kugera kuri microne 0.8-1,6, impeta ipfa ubukana ni microni 0.8, imashini iboneye kubintu bikoreshwa, nta gusya.
