Ngokusebenza kakuhle kwemveliso, ukungcoliseka kwendalo esingqongileyo kunye neendleko eziphantsi zemveliso, i-EPC ithathwa njengetekhnoloji entsha yokulungisa izinto zenkulungwane yama-21. I-RETE yinxalenye ebalulekileyo yomatshini wokusebenza we-metring, umatshini wokutya onobuqili kwi-rate kwi-quation, i-Ash Slag idlala indima yobushushu, i-scress ifuna ukumelana nobushushu, rand cr2mi2s. Ubungakanani bemigca ye-Grate String i-70 mm ephezulu, i-40 mm ububanzi kunye ne-800 mm ubude, kunye nobunzima obungenanto yi-19 kg. Itekhnoloji yokuphosa ifuna ukuqhubekeka ngokupheleleyo, akukho ziphene zokuhlaselwa zivunyelweyo kumhlaba wokusebenza, kwaye kufuneka impumelelo ekusebenzeni kakuhle. Ingabonwa ukuba nangona ubume be-Grate String ilula, ineemfuno eziphezulu zetekhnoloji yemveliso kunye netekhnoloji.
Ukuveliswa komtya we-GRATY nge-EPC yinkqubo ephezulu nefanelekileyo. Ukugxininisa kwiingxaki zokubandakanywa kunye nesanti ukubandakanywa kwimo yendlela yokuphosa i-Commol, kunye nezizathu zokuphononongwa kwenkqubo yokuphononongwa, ukuze kuphuculwe ukusebenza ngempumelelo kwenkqubo yokuphosa.
Inkqubo yoqobo kunye nenqanaba lemveliso
1.1 Iiparamitha zenkqubo yentsusa, yamkele indlela yemveliso yendlela elahlekileyo. Iqela ebhokisini liyamkelwa kwimodeli, kwaye imifula izaliswe yipeyinti emanzi. Ubungakanani bebhokisi yesanti yi {}}} mm ubude, 1 200} mm ububanzi kunye ne-800 mm ephezulu. Ibhokisi nganye iqulethe iqela le-1 lemifanekiso, kwaye iqela ngalinye livelisa iimodeli ezili-12. Inkqubo yobukrakra iboniswe kwi-Fig . 2. ubushushu bokuphosa bu- 1 620} uxinzelelo olubi ngu -0.
1.2 Inkqubo yoqobo yeempawu kunye nomgangatho wokuphosa
1.2.1 Iimpawu zenkqubo yoqobo
Kukho umngcipheko emibini ekuphoseni kwinkqubo yoqobo. Ulwelo lwentsimbi luthunyelwe ekuphoseni ukusuka kumphakamisi omnye. Ukuphakama ekugqibeleni kukude kukukhubazeka kubanda, kwaye isiphelo esikufuphi neSprue ngumsindo oshushu. Umgama wokukhula okhukuliseko kwinkqubo yoqobo ilingana namaxesha ama-3 obo bubukhulu benxalenye yokuphosa. Ngenxa yefuthe lokugula elihluphekayo lokukhubazeka kude kube sekupheleni, indawo ephakathi yokuphosa ayinakutyiwa ngaphaya komgama wokutya, ke le nkqubo yokondla ayinangqondo. Ubungakanani bebhokisi yesanti inkulu, enokufumana izindululo ezingaphezulu. Nangona kunjalo, inkqubo yokuvelisa iziqwenga ezili-12 zeqela lemodeli kwibhokisi enye kwaye zingcwabe kuphela ungqimba olunye kwibhokisi engcwatywe ayinangqondo. Isithuba sebhokisi yesanti ayisetyenziswa ngokufezekileyo, kwaye ukuvelisa impumelelo kusezantsi kakhulu.
1.2.2 Ukuphosa umgangatho
I-1) I-Cafings nge-Slag kunye neSanti Ukubanjwa kweSanti ibandakanywa ngokupheleleyo, ifuna umgangatho wokuphosa okuphezulu. Kodwa ngenxa yokusetyenziswa kohlobo lweBhokisi yeBhokisi, ngenxa yoko amandla amalungu azaliswe yipeyinti emanzi ayonelanga, i-adheni ayomelele, yeyakwiindawo ezisengozini zengxaki. Ngexesha lokugalelwa, ezi ndawo zixhotyisiweyo ziya kwaphulwa liqondo lokushisa eliphezulu, elikhokelela ekuphoseni isiphene nesanti. In addition, in the casting process, because the actual use of the casting is not taken into account, the actual working face of the casting is upward in the direction of the casting position, but the working face of the casting is not allowed to have defects, resulting in the casting scrap due to slag and sand. Iziphene ze-Slag kunye nesanti zibandakanywa emva kokuba zigqityiwe zibonisiwe kumzobo 3.
2) I-pores esongelweyo ivela kumphezulu wemifanekiso. Ngokutsho kobume besiphene, kugqitywe ukuba umphunga wamanzi owenziwe ngumdlalo odadayo akasomi ngokwaneleyo ukubangela iipores. Ngenxa yenkqubo yemveliso, oku kukuba, umsebenzi ukwimo yokumisa kwaye ujonge ikhonkco ukuba ungabi nangqondo, kubangela ukuba i-cast ukungafumani ukomisa ngokupheleleyo. Ubume besiphene seStomal siboniswe kumzobo 4.
2. Inkqubo yenkqubo kunye nefuthe lokufaka isicelo
2.1 Ulungelelwaniso lwenkqubo
Ngokweengxaki kwimveliso yokwenyani kunye nesizathu sokuphosa i-scrap, inkqubo yokuphosa i-Grate Strip ilungiselelwe.
2.1.1 Ukuphuculwa kokugada ukhula
Ukwenzela ukwandisa uzinzo lwenkqubo, uyilo lokuphuphuma komgangatho lutshintshiwe. Intokwa-ntandathu ihamba isondele embindini wendlela yokuphosa. Ngokokubalwa komgama wokutyibilikwa, iziko lokunyuka yi-260 mm kude nakwiziphelo zombini zokuphosa, kwaye ukondla kunokufezekiswa endaweni. Zintathu ii-grate nganye phenyane. Ukongeza, isango langaphakathi linxibelelana ngqo nabakhweli babini ukufezekisa ukondla okushushu, kwaye kwenza intsimi yokutya, kwaye yenza intsimi yobushushu ekuphoseni isengqiqweni. Emva kokuphumelela, iqhinga lenkqubo yokutshata yi-60 mm × 60 mm, i-sprue ingama-60 mm × 50 mm × 40 mm × 40 mm × 40 mm. Iqela lemodeli linamacala amathathu, kwaye umgama phakathi kwengqimba nganye yi-60 mm.
2.1.2 Ukulawulwa kwesiphene
1) I-Slag kunye nesanti ukubandakanywa, ubuso bendawo yokuphosa iya kuba phantsi kwicala lendawo yokugalela ukuqinisekisa umgangatho wobuso bokusebenza; Ukusebenzisa iqela ngaphandle kwebhokisi, ukuqinisekisa ukuba imodeli i-Airlight emva kokuqala, ukuthintela iinxalenye ezibuthathaka zomonakalo obambeleyo obangelwe yi-staint, isiphene sesanti; Ikomityi ye-piruper isetyenziswa. Xa ukhathazeka, iNdebe yeSpuer ifanele iphinde ivuthwe. Xa ungcwaba ibhokisi, isanti ye-resarn ibekwe kwi-Pifuer yeNdebe yeSprue ukuze kuqinisekiswe amandla endebe ye-sprue, ukuze ulawule unxibelelwano phakathi kweNdebe yeSprue kunye neSprue.
2) I-Stomata
Kuyimfuneko ukulawula ngokungqongqo kwimiba yolawulo, inkqubo yokufezekiswa kunye nokubekwa esweni kunye nokuhlolwa ukuqinisekisa ukomisa kunye nokuthintela ukomisa. Ukuze ingxaki angenzi ntshukumo, umzi-mveliso kufuneka aqeqeshe abasebenzi kunye nabasebenzi abalawulayo, ukuze iliso labelwe umntu, iliso libekade likhona, kwaye ikhonkco ngalinye lisikelwe umda ukuthintela isibonelelo senqanaba eliphantsi.
2.2 Isiphumo seSicelo
Ulungelelwaniso lwantlandlolo lwe-moldm emhlophe kukhokelela kwinqanaba lokusetyenziswa eliphantsi lwebhokisi yesanti. Iingqimba ezimbini ezingaphezulu zezokulahleka zinokubekwa kwicala lokuphakama ukuze kufezekiswe ukugalelwa ngama-36 eengcaciso ezi-3 zeqela lemodeli. Ngokwalo mbono, indlela yenkqubo yokuphosa i-Grate Strip inokufunyanwa kumzobo weqela lesi-5, emva kokupheliswa kwesango, ukuvelisa impumelelo kuyancitshiswa ngamaxesha ama-3, kwaye indleko incitshisiwe. Kwinkqubo yemveliso ye-batch encinci, iziphene ze-Slag kunye nesanti ukubandakanywa kokuphosa zilawulwa ngempumelelo, kwaye iqondo lokwaliwa lelitha lingaphantsi kwe-5%. Okwangoku, inkqubo ye-batch ifikelelekile, inkqubo iyazinza, akukho mngxunya we-shrinkge, i-shrinkage, i-slog, isanti kunye nezinye iziphene zifunyenwe emva kokuphoswa kwenkqubo.
3 ISIQINISEKISO
1) Ngokwenza inkqubo yokuphononongwa, ukusebenza kwemveliso yokuphosa kuyaphucuka ngokufanelekileyo kwaye iindleko zemveliso zincitshisiwe.
2) Ukusoma okumhlophe kunye nokudibanisa okubhaliweyo kubaluleke kakhulu, kufuneka yome, ukuthintela iziphene ezibangelwa ngumphunga wamanzi.
3) Ukubumba ngaphandle kwebhokisi kunokuphepha isiphene somonakalo wendawo enendawo yokubiyela kunye nesanti. Inkqubo yokuphosa inokuba zizinzile ngokuhlengahlengisa isikhundla sokuphelisa isikhundla sokugalela kwaye sisebenzela ukuphosa ukuphulula.
I-4) Inkqubo efanelekileyo yamkelwe kwaye ikhuthazelwe kumzi-mveliso, kwaye imveliso enkulu iqinisekisile ukuba le nkqubo isebenza kakuhle kunye nomgangatho wemveliso ethembekileyo.
