Indlela yokujongana nemingxunya yesanti kwimveliso yodonga oluncinci lwe-ductile

Ngokuphathelele isiphene sesanti senzeka kwimveliso ye-gucile inyibilikisi (ubukhulu be-Wall Iindlela ezithile zonyango zezi zilandelayo:

1. Hlaziya unobangela wemingxunya yesanti. Eyona nto iphambili kwimingxunya yesanti kukwakha imingxunya kumphezulu okanye ngaphakathi kwemingxunya ngenxa yokufaka okanye ukukhutshwa kwamasuntswana ngexesha lokugcwalisa isinyithi. Amancinci amancinci ajongene nokungcola, amandla, kunye nokuphosa uzinzo kwisanti ebumbayo ngenxa yobunzima babo bobunzima, ukuqina okukhawulezayo, kunye nenqanaba lokuqhuba lentsimbi. Unobangela oqhelekileyo ubandakanya ukusebenza kwesanti engonelanga, ukungcola okuphantsi, amandla amanqam anqabileyo, njenge-sio ₂ yomxholo okanye i-scocking esebenzayo). Imodeli Inkqubo yokulinganisa imodeli: Ukungaveleli kwendawo ye-Sand Bulls (njengeekona kunye nokuvuza kwesanti), kunye nomgangatho webhokisi yesanti (njengamandla aphantsi kwezakhiwo zokulungisa). Uyilo olungenangqondo lwenkqubo yokuthulula: Inqanaba eliphezulu lokuhamba kwinqanaba lokulinganisa ngaphakathi lukhwela udonga, ubuthathaka be-Slag Blog (i-Slag Angetion), kunye nokutshintsha okukhulu kubushushu / isantya esikhulu.

2. Amanyathelo athatyathiweyo

a. Yenza inyathelo lokwenza isanti yokubumba ukuphucula ukubekwa kwengqungquthela kunye nokufana: lungisa iiparamitha zomatshini wesanti Ukuphucula ukwakhiwa kwesanti: isanti yesanti ephakathi ye-sodium esekwe kwi-Bentotite ye-sodium esekwe (ibuyisela i-calcium esekwe) ukuya kwi-4-6% (i-accounting yesanti yantlandlolo) yokuphucula amandla aphezulu; Lawula umgubo osebenzayo we-coalr nge-3-5% (yenza ifilimu ye-carbon), kwaye isixa sentlabathi ehlaziyiweyo kufuneka ibe ≤ 50% (ukunciphisa uthuli). Ukulawulwa komswakama: Umgaqo wokufuma kwentlabathi eluhlaza kufuneka igcinwe kwi-3.5-4.0% ukuthintela ukuba phezulu kakhulu (ukunciphisa amandla) okanye ukudityaniswa komxube wesanti.

b. Ukuphucula indlela yokugcina imodeli yemodeli kunye ne-Santi Conset: Jonga ukungcola kwetemplate yetemplate (ukunqanda ukugqobhoza ibhokisi yesanti Ukulawulwa komgangatho wokulungiswa kwe-mold: kuphephe ukwenza ibumba ithambile kakhulu. Sebenzisa isanti eninzi egudileyo (njengokudibanisa inani elincinci lodongwe) kunye neCompact indawo yokulungisa. Akuvumelekanga ukuyigcwalisa ngodaka.

c. Yenza uyilo lwenkqubo yokuthulula ukunciphisa ireyithi yokuhamba kunye nokhuphiswano lwenkqubo yokutsala (F ngokuthe ngqo: I-Inner-1: 2: 2 ~) i-0.5-1.2: i-s (iphantsi kancinci kwi-0.5). Yongeza i-buffting kunye nokucoca: yongeza iingxowa ze-bufftic (njengee-ceramic rings) ezantsi kwe-0.5-1.0mm ye-Poramic (kunye nobungakanani be-ceramic (ngobukhulu be-ceramic (kunye nokucoca i-slag. Matching pouring parameters: pouring temperature: ductile iron liquidus line is about 1150 ℃, and it is recommended to pour ultra-thin wall castings at a temperature of 1390-1450 ℃ (for thin-walled parts, the upper limit should be taken to avoid excessive overheating and erosion). Ukuthulula Isantya: Ukukhawuleza kunye nokuqhubeka nokugalela ukuphazamiseka kubangela ukufuduswa okanye imingxunya yesanti yendawo.

d. Ukomeleza ukhuseleko lwesanti ubumba kwaye usebenzise iingubo ezinganyangekiyo zomlilo: Faka isicelo se-Alumina Alumina Alumina Aluminas 80-120 mesh) kumphezulu we-mold cavity, ngobukhulu be-0.2-0.3mm. Emva komonga, yenza i-worter yodwa ukunciphisa ukungena kwe-molten yentsimbi. Ukudibana kufanele ukuba iyunifomu kwaye uphephe ukuqokelelwa (ngenye indlela ukuphefumla okusulelekileyo kunokubangela iipores).

e. Lawula umgangatho kunye nokuzinza kwenkqubo yentsimbi ye-molten: qinisekisa ubushushu kunye nokuqulunqwa kwentsimbi ye-molten nge-1550-1560, kwaye kunqande ukwenziwa kweqondo (c: 2,4-2.8%). Unyango lwe-SLAG: Ngaphambi kokugalela, ukucoca umphezulu we-slag yentsimbi okanye ukusebenzisa i-slag valng cotton / stimmer ukhusela i-stavity ye-stavity kunye ne-stales esinemikhono yesanti.

f. Uhlalutyo lwedatha kunye nokuqinisekiswa kweempawu ezinesiphako: Bala indawo (ezinje ngesango, indawo yotshintsho), ubungakanani, kunye ne-morphology (kwaye ichonge ukuba ingaba banxulumene nale ndawo ethile yenkqubo). Uvavanyo lokuthelekisa: Emva kokulungelelanisa umlinganiso wentlabathi okanye ukuhambisa iParameter, ukuveliswa kwetyala elincinci kwenziwa ukuthelekisa inqanaba lokubetha kwesanti kwaye uqinisekise indlela yokuphucula.

3. Isishwankathelo

Imingxunya yesanti kwizinto ezincinci ezilawulwa ngokuqondakaliswa "ukuqiniswa kwentlabathi + yokuphosa uzinzo + lwenkqubo yokuzinza". Isitshixo kukuphucula amandla kunye nokuchasana komlilo kwesanti yokubumba, yiyile inkqubo yokuthulula ofanelekileyo ukunciphisa inqanaba lokuhamba, kwaye ulawule ngokungqongqo ukwenziwa kweenkcukacha ezisemgangathweni kunye neenkcukacha zomsebenzi zentsimbi etyhidiweyo. Ukuba yintlabathi ye-resen yesanti, igalelo labo eliphezulu linokunikwa ingqalelo ephambili; Isanti yodongwe ifuna uhlengahlengiso oluhle lwe-Bentotite, umgubo wamalahle, kunye nokufuma, ukudityaniswa nokhuseleko oluhlekisayo, ukunciphisa ngokufanelekileyo isiphene sesanti.
