Uburyo bwo kwinjiza itanura
Carburizing agent ikwiranye no gushonga mu itanura rya induction, ariko imikoreshereze yihariye ntabwo ari imwe ukurikije ibisabwa.
.
. irashobora kuba nka 90, niba ubushyuhe buke bwa carburizing, ni ukuvuga, kwishyuza gushonga gusa igice cyubushyuhe bwicyuma gishongeshejwe ni gito, agent ya carburizing yose imaze kongerwaho icyuma cyamazi, Mugihe kimwe, ikanda mumazi icyuma hamwe nubushakashatsi bukomeye kugirango bugumane hejuru yicyuma cyamazi. Ubu buryo bushobora kongera karburizasi yicyuma cyamazi hejuru ya 1.0%.
Gukoresha neza agent ya carburizing mumatanura ya induction
1, gukoresha itanura ryamashanyarazi 5T cyangwa menshi, ibikoresho fatizo nibimwe kandi bihamye, turasaba uburyo bwo kongeramo uburyo. Ukurikije ibisabwa mubirimo karubone, ukurikije igipimo cyibigize, agent ya carburizing hamwe nicyuma cyicyuma hamwe na buri cyiciro cyibikoresho kugirango uhuze itanura mugice cyo hepfo, igice cyicyuma cyishyuza urwego rwibikoresho bya carburizing, igipimo cyo kwinjiza karubone kirashobora kugera kuri 90% -95%, carburizing agent mugushonga ntugacike, ubundi byoroshye gupfunyika mumyanda, bigira ingaruka kumyuka ya karubone;
2. Itanura ryo hagati ya induction yo hagati ya 3T irakoreshwa, kandi ibikoresho fatizo ni kimwe kandi gihamye. Turasaba inama yo kongeramo uburyo. Iyo icyuma gishongeshejwe gishongeshejwe cyangwa kigasigara mu itanura, umukozi wa carburizing yongerwaho hejuru yicyuma gishongeshejwe mugihe kimwe, hanyuma icyuma cyongeweho ako kanya. Umukozi wa karburizingi akanda mucyuma gishongeshejwe, kugirango umukozi wa carburizing ahure rwose nicyuma gishongeshejwe, kandi igipimo cyo kwinjiza kirenga 90%;
3, gukoresha itanura rito ryumuriro wamashanyarazi, ibikoresho bibisi hamwe nicyuma cyingurube nibindi bintu byinshi bya karubone, turasaba ko carburizing agent ikora neza. Nyuma yicyuma / gishongeshejwe icyuma gishonga, hindura ibirimo karubone, birashobora kongerwaho hejuru yicyuma / icyuma gishongeshejwe, binyuze mumyuka ya eddy ikurura amazi yicyuma (icyuma) cyangwa ibihimbano byo gushonga no kwinjiza ibicuruzwa, igipimo cyo kwinjiza karubone ni hafi 93%.
Hanze yuburyo bwa carburisation
1. Shira ifu ya grafite imbere mumufuka
Ifu ya Graphite nkibikoresho bya carburizing, bihuha bingana na 40kg / t, birashobora gutegurwa gukora karubone yibyuma byamazi kuva kuri 2% kugeza kuri 3%. Mugihe karubone yibyuma byamazi byiyongereye buhoro buhoro, igipimo cyo gukoresha karubone cyaragabanutse. Ubushyuhe bwicyuma cyamazi mbere ya karburizasi yari 1600 and, naho ubushyuhe buringaniye nyuma ya carburisation bwari 1299 ℃. Graphite powder carburisation, mubisanzwe ukoresha azote nkuwitwara, ariko mubihe byumusaruro winganda, umwuka ucogora biroroha, kandi umwuka wa ogisijeni mumyuka uhumeka kugirango utange CO, ubushyuhe bwimiti irashobora kwishyura igice cyigabanuka ryubushyuhe, hamwe nikirere kigabanya CO ni byiza kunoza ingaruka za carburisation.
2, gukoresha ibikoresho bya carburizing
100-300 ya grafite ifu ya carburizing irashobora gushirwa mubipaki, cyangwa kuva mumasoko yicyuma hamwe nuwinjiramo, nyuma yicyuma kiva mumazi kimaze kuvangwa neza, uko bishoboka kwose kugirango ushire karubone, igipimo cyo kugarura karubone kiri hafi 50%.
Mugukoresha carburizing agent igomba kwitondera ikibazo
Niba igihe cyo kongeramo ibikoresho bya carburizing ari kare cyane, biroroshye kubihambira hafi y itanura, kandi agent ya carburizing ifatanye nurukuta rwitanura ntabwo byoroshye guhurizwa mubyuma byamazi. Ibinyuranye, kongeramo igihe bitinze, bizatakaza amahirwe yo kongeramo karubone, bivamo gushonga, gushyushya buhoro. Ibi ntibidindiza gusa igihe cyo gusesengura imiti no kubihindura, ariko kandi bishobora no guteza ingaruka ziterwa nubushyuhe bukabije. Kubwibyo, carburizing agent cyangwa mugikorwa cyo kongeramo ibyuma bito buhoro buhoro kugirango winjire.
Nko mugihe cyiyongereyeho byinshi, birashobora guhuzwa nitanura rya induction mugihe ibikorwa byo gushyushya ibyuma byamazi bifatanije no kubitekerezaho, kugirango harebwe ko carburizer mugihe cyo gufata ibyuma byamazi ya 10Min, kuruhande rumwe binyuze mumashanyarazi. Ingaruka ya karburizer ikwirakwizwa ryuzuye, kugirango igire ingaruka. Kurundi ruhande, ingano ya azote yazanwe muri karburizeri irashobora kugabanuka.
Ntukongereho rimwe, ongeramo ibice, hanyuma ushonge igice, shyira igice cyicyuma gishyushye (hafi yipaki) mumufuka, hanyuma usubire mumuriro wa carburizer inshuro 1-2, hanyuma ushireho, ongeramo amavuta.
Hariho ibintu byinshi ugomba kwitondera:
1. Carburizing agent biragoye kubyakira (nta kubara);
2, carburizing agent ivu ryagabanijwe ntabwo ari kimwe;
3. Kwinjira bitinze;
4. Uburyo bwo kwishyira hamwe ntabwo arukuri, kandi guhuza ibice byemewe. Irinde indorerwamo y'ibyuma byamazi na slag cyane iyo wongeyeho;
5. Gerageza kudakoresha ibikoresho byinshi byangiritse.
Ibiranga ubuziranenge bwa carburizing agent
1, ingano yingirakamaro iringaniye, ububobere ni bunini, umuvuduko wo kwihuta urihuta.
2. Ibigize imiti yuzuye, karubone nyinshi, sulfure nkeya, ibintu bito byangiza cyane, umuvuduko mwinshi.
3, ibicuruzwa grafite ya kristu yuburyo bwiza, itezimbere ubushobozi bwumwimerere bwa nucleation ubushobozi. Ongera umubare wa nodular fer nodules mugukingirwa, kandi wongere nucleus ya grafite mumashanyarazi yumuriro wicyuma. Gutunganya ndetse no gukwirakwiza wino yimyanda muri casting.
4. Imikorere myiza kandi itajegajega.
Guhitamo imiti ikwiye ya carburizing ifasha kugabanya ibiciro byo gushonga, kuzamura ubwiza bwicyuma no gushiramo, kugirango uruganda rushonga, guta
