Impamvu zo gucamo impeta ziragoye kandi zigomba gusesengurwa birambuye; icyakora, barashobora kubivuga muri make kubwimpamvu zikurikira:
1. Byatewe nimpeta ipfa ibikoresho kandi bifite ireme
1)Ibikoresho bikoreshwa mu mpeta bipfa ni imwe mu mpamvu zingenzi. Kugeza ubu, impeta y'Ubushinwa ipfa gukoresha cyane cyane 4Cr13 na 20CrMnTid, ihagaze neza. Ariko, hariho abakora ibikoresho bitandukanye. Kubikoresho bimwe, hazabaho itandukaniro mubintu bigize ibimenyetso, bizagira ingaruka kumiterere yimpeta.
2)inzira yo guhimba. Iri ni ihuriro ryingenzi mubikorwa byo gukora. Kubikoresho byifashishwa cyane byuma byuma, mubisanzwe haribisabwa muburyo bwa metallografiya nko gukwirakwiza karbide mubikoresho. Ubushyuhe bwo guhimba bugomba kandi kugenzurwa cyane, hagomba gushyirwaho uburyo bunoze bwo gushyushya, hakwiye gukoreshwa uburyo bwo guhimba, kandi gukonjesha buhoro cyangwa gufatira mugihe nyuma yo guhimba bigomba gukorwa. Inzira zidasanzwe zirashobora gukurura byoroshye gucikamo impeta umubiri upfa.
3)Imyiteguro yo kuvura ubushyuhe. Ukurikije ibikoresho nibisabwa mubibumbano, inzira yo gutunganya ubushyuhe bwateguwe nka annealing, kuzimya hamwe nubushyuhe bikoreshwa mugutezimbere imiterere, gukuraho inenge zubatswe muguhimba no kubeshya, no kunoza imikorere. Uburyo bukwiye bwo gutunganya ubushyuhe bwo gutunganya ibyuma bya karubone binini cyane birashobora gukuraho karbide y'urusobe, spheroidize no gutunganya karbide, kandi bigateza imbere gukwirakwiza karbide. Ibi bizafasha kwemeza ubwiza bwo kuzimya no gutwarwa no kongera ubuzima bwububiko.
2. Impeta ipfa kuvura ubushyuhe
1)kuzimya no kurakara. Numuhuza wingenzi muburyo bwo kuvura ubushyuhe. Niba ubushyuhe bukabije bubaye mugihe cyo kuzimya no gushyushya, ntibizatera gusa ubugome bukabije bwakazi, ahubwo bizanatera byoroshye guhinduka no gucika mugihe cyo gukonja, bigira ingaruka zikomeye kubuzima bwikibumbano. Ibisobanuro byo gutunganya ubushyuhe bigomba kugenzurwa cyane kandi hagomba gukoreshwa uburyo bwo kuvura ubushyuhe. Ubushuhe bugomba gukorwa mugihe nyuma yo kuzimya, kandi hagomba gukoreshwa inzira zitandukanye zubushyuhe ukurikije ibisabwa bya tekiniki. ?
2)guhagarika umutima annealing. Ifumbire igomba gukorerwa imihangayiko nyuma yo gutunganywa bikabije kugirango ikureho imihangayiko yimbere iterwa no gukora imashini ikabije kugirango wirinde guhindagurika gukabije cyangwa guturika biterwa no kuzimya. Kubibumbano bifite ibisobanuro bihanitse bisabwa, ubuvuzi bwokugabanya ubukana burakenewe nyuma yo gusya, bikaba byiza muguhindura neza imiterere no kongera ubuzima bwa serivisi.
3. Gufungura igipimo cyimpeta
1)Niba igipimo cyo gufungura impeta ipfa ari kinini cyane, amahirwe yo gupfa impeta aziyongera. Buri ruganda rukora impeta ruzagira itandukaniro rinini bitewe nuburyo butandukanye bwo kuvura ubushyuhe. Mubisanzwe, ibicuruzwa byisosiyete yacu birashobora kongera igipimo cyo gufungura 2-6% hashingiwe ku bicuruzwa byo mu rwego rwa mbere byo mu gihugu, kandi birashobora gutuma ubuzima bwa serivisi bubaho.
4. Impeta ipfa kwambara
1)Iyo impeta ipfuye yambarwa mububyimba runaka kandi imbaraga zikagabanuka kugeza aho idashobora kwihanganira umuvuduko wa granulation, gucika bizaba. Birasabwa ko impeta ipfa gusimburwa mugihe impeta ipfuye yambarwa kugeza aho ibizunguruka byerekana umuvuduko.
5. Gukoresha impeta bipfa
1)Mugihe cyo guhunika impeta ipfa, ubwinshi bwibintu byinjira ntibushobora kwemererwa gukora ku mutwaro 100% kubera umusaruro mwinshi w’impeta bipfa ubwabyo. Ibikorwa nkibi birebire kandi byimbaraga nyinshi nabyo bizaganisha kumeneka impeta ipfa. . Turasaba kugenzura umutwaro kuri 75-85% kugirango ubuzima bwa serivisi bwimpeta bupfa.
2)Niba impeta ipfuye kandi uruziga rukanda cyane, gucika bishobora kubaho byoroshye. Mubisanzwe, turasaba ko intera iri hagati yimpeta ipfa na roller yumuvuduko igomba kugenzurwa hagati ya 0.1-0.4mm.
6. Ku cyumweru
1) Kumeneka birashoboka cyane mugihe ibintu bikomeye nkibice byicyuma bigaragara mubikoresho byasunitswe.
7. Impeta zipfa kwishyiriraho nibibazo bya granulator
1) Impeta ipfa ntabwo yashyizweho neza kandi hariho intera hagati yayo na granulator. Impeta ipfa irashobora kandi gucika mugihe cyo guhunika.
2) Nyuma yo kuvura ubushyuhe, impeta yimpeta izahinduka cyane. Niba bidakosowe, impeta yimpeta izacika mugihe cyo kuyikoresha.
3) Iyo granulator ubwayo ifite inenge, nkigiti kinini cya granulator ihinda umushyitsi, nibindi.
