Indlela yokujongana neziphene ezibandayo ezinesiphene esinemigangatho emincinci exineneyo yentsimbi?

Ukuvela kwe-Fough Fought kunye ne-Dough Applies yokuThengiswa kweendawo ezincinci ezixineneyo zentsimbi yentsimbi yingxaki eqhelekileyo kwimveliso. Izinto ezinodonga ezitshisiweyo zihlazisa ngokukhawuleza ubushushu, kwaye i-ductile inyibilikisa ihlwempuzekile kune-iron yentsimbi, yenze kube lula ukuqinisa ngaphambi kokuba i-molvity ye-molle izaliswe yintsimbi etyhidiweyo. Ukucombulula le ngxaki kufuna ukuba usebenze lwenkqubo kwimiba emininzi.

Umbono ophambili: Phucula ulwelo lwentsimbi enyibilikisiweyo, ukukhawulezisa isantya sokugcwalisa, ukulibazisa ukuphola kwe-mold cavity, kunye nokuphucula ukuphazamiseka. Oku kulandelayo ngamanyathelo athile anokuthathwa:

I-1. Yenza ubume kunye nonyango lwentsimbi enyibilikisiweyo: Ukunyusa ikharbon elinganayo (CE): Ngelixa iqinisekisa i-spbonmentral (CE), ngakumbi i-spbon elinganayo (ikhabhoni ye-swicon). Le yeyona ndlela isebenzayo yokuphucula ukungabinamali. Iinxalenye ezinqabileyo zentsimbi zivumela amaxabiso e-Cep (zihlala 4.3-4.7%), enokuzama ukufikelela kumda ophezulu okanye ngaphezulu (intsebenzo kufuneka iqinisekiswe). Ibeka phambili umxholo wekhabhoni, ulandelwa ngokujonga isilicon. Ngokungqongqo ulawule umxholo wesalfure ye-iron ye-molten ye-molfur: i-sulfur esezantsi sisiseko sokungasebenzi kakuhle. I-sulfure ephezulu iya kutya i-spheroding agents, ivelise i-Slag, kwaye inciphise ulwahlulo. Ithagethi ye-iron entshukumo ye-slten iphantsi kwe-0.02%. Ukuphucula inkqubo yokubuyiswa kwe-spresidis: ukusebenzisa i-inoculants efanelekileyo (efana ne-Silicon Bagium Calcoum), ukhuseleko oluninzi lwenziwa (kwi-inpoupation eninzi) Ukuzalwa ngokuhamba kubalulekile ekuphuculeni ukungabinakho nokunqanda ukwehla. Lawula isixa semali yearhente yokufihlakala: Qinisekisa ukukhutshwa okuhle (Inqanaba elifanelekileyo ≥ 3), iarhente egqithisileyo igqithisileyo iya kwandisa i-SLAG kunye nee-oxis. I-MG eqhelekileyo kufuneka ilawulwe nge-0.03-0.05%, kwaye i-res entsukeleyo ayifanele iphakame kakhulu. Ukuphakamisa amaqondo obushushu okugada: Eli linyathelo elibalulekileyo kwizinto ezinqwenelekayo. Ukwandisa ngokufanelekileyo amaqondo obushushu okugalela anokwandisa kakhulu ulwelo lwe-iron etyhidiweyo kwaye wanyusa ixesha lokuzalisa. Uluhlu lobushushu ekujoliswe kubushushu luhlala lufuna ukuba yi-1400 ° C, kunye ne-1420-10-120-120-120-10 cume (iimfuno ezithile ekufuneka zimiselwe ngokusekwe kwisakhiwo sokupholisa, kunye novavanyo lwenkqubo yoyilo). Kodwa kuyimfuneko ukulungelelanisa umngcipheko we-shrinkage, i-slag ekrwelwe, kunye namacala entlabathi ebangelwa ngamaqondo obushushu aphezulu. Qinisekisa ukucoceka kwentsimbi ye-mollen: Ukomeleza ukususwa kunye nokuvala i-fudle icocekile, kwaye faka i-scrue nozzle icocekile okanye isebenzise i-scrue screen (i-oxide) yokungena kwi-slavity kunye nokuhamba okuphumayo.

2. Yenza uyilo lwenkqubo yokuthulula: Le yikhonkco eliyintloko ukusombulula ingxaki yokubanda kubandayo obandayo. INKQUBO YOKUVULA YOKUVULA: Yandisa indawo enqamlezileyo ye-Sprue: Iinxalenye ezinamacala anqabileyo, indawo enkulu yecandelo le-sprue ye-sprue ifuneke kwi-iron ye-onld kwi-moltity ngesantya esikhawulezayo kwaye sizalise ngaphambi kokuqina. Kungayimfuneko ukwandisa inani okanye ububanzi be-sprues. Nciphisa inkqubo kwaye usasaze intshayelelo: Uprunes kufuneka usasazwe kufutshane neendawo ezinamagqabi okuphosa kangangoko kunokwenzeka ukuba umgama wentsimbi uqhwithela. Kulumkele ukuhamba ixesha elide kwi-iron etyhidiweyo kwi-mold cavity. Ngezinto ezinzima ezixineneyo ezixineneyo, iziqholo ezininzi zinokufuneka. Ukucutha inqanaba lokuhamba kwesigcawu: Nangona ukugcwaliswa ngokukhawuleza kuyadingeka, ireyithi yokuhamba okugqithisileyo inokubangela ukutshiza, i-curling, kunye nokwandisa i-slaxide yesibini. Ngokwandisa indawo enqamlezileyo ye-Sprue, inqanaba lokuhamba linokuncitshiswa ngelixa kuqinisekisa umgangatho wokuhamba. Yongeza ukuphakama kweSprue / Sebenzisa iiNdebe yeSprue: Phakamisa i-Inder yensimbi kwaye unyuse amandla okugcwalisa. Cinga ngenkqubo yokuthulula inyathelo: Kwizinto ezinodonga ezinamanqanaba aphezulu, sebenzisa iimbaleki eziphezulu zokwazisa ungqimba olusuka ezantsi, embindini, okanye ngaphezulu, okanye ngaphezulu komgama wokuhamba kwentsimbi. Sebenzisa "ububanzi, iflethi elicekeceke, kwaye iflethi" yinzuzo ye-iron ukuze ingene kwi-mold can ngokuthe tyaba ngokuthe tyaba, ngokuzinzileyo, kwaye ihluze indawo enkulu.

3. Yomeleza ukungabinamsebenzi: Ukuseta ngokupheleleyo imingxunya / ngeyona ndawo iphakamileyo ye-mold cavity, indawo yokugcwalisa intsimbi yentsimbi (elona nqanaba linganeleyo kunye nengqokelela yokuphelisa kunye nokuqokelelwa kwe-stag). Qinisekisa ukuba irhasi ngaphakathi kwe-mold cavity ingagxothwa ngokukhawuleza ukuthintela "ibhloko yegesi" ethintela ukugcwaliswa kwentsimbi etyhidiweyo. Jonga i-thessical moya yesanti ebunjiweyo: Qinisekisa ukuba isanti yokubumba (ngakumbi isanti yomphezulu) inomoya owoneleyo womoya. Umxholo wokufuma kwesanti eluhlaza ufanele ukuphakama kakhulu. I-compact efanelekileyo yokuthintela ukuqina kwendawo echaphazela ukuphelisa.

4. Yenza umsebenzi wokuqalisa: Ukuthulula ngokukhawuleza: Umsebenzi othululwayo kufuneka agxile kwimizamo ephezulu yokufezekisa ukuhamba okuphezulu kwaye aqiniseke ukuba isinyithi esifutshane sinobushushu obaneleyo kunye namandla e-kinetic ukugcwalisa i-sevity ye-sld. Ixesha lokugalela ixesha elide sesinye sezizathu eziphambili zokushunyayelwa kwezinto ezinamagqabi. Ukuphapha okuqhubekayo: Inkqubo yokugada kufuneka iqhubeke kwaye ayinakuphazamiseka. Ukuphazamiseka kokuhamba kunokubangela isithintelo esibandayo kwindawo yokuphazamiseka. Ukuthulula ixesha: emva kokuba unyango lokungafakwanga i-spisid lugqityiwe, kufuneka luthulule ngokukhawuleza (ngesiqhelo kwimizuzu engama-8 ukuya kweli-10) ngaphambi kokufumana isiphumo sobuchule bokufakwa kwemveliso kunye nolwelo.

5. Olunye ukuqwalaselwa: Jonga ubunzima kwi-iron etyhidiweyo ukuqinisekisa ukomelela okwaneleyo kokuthulula, kuthathelwa ingqalelo iimfuno zenkqubo yeSprue. Ukucutha inani le-cores / i-proough of theript: Iisanti ezintsonkothileyo zinokuthintela ukuhamba nokuphelisa. Yenza uyilo oluphambili ukuze uqiniseke ukukhuthala okuthandekayo (njengokubeka i-ducts enamandla, kusetyenziswa iintambo zokugcina iintambo / i-wax, kunye nokusebenzisa isanti ephefumlelweyo). Amandla kunye nokuqunjelwa kwisanti yokubumba: Qinisekisa ukuba isanti yokubumba inamandla aneleyo okuxhathisa ukhukuliseko lwe-iron encwina kunye nokuthintela isanti yokuthintela i-sprue okanye i-cavity. Kodwa ukungasebenzi kufanele ukuba iyunifomu ukuthintela ubunzima bendawo echaphazela i-shrinkage okanye ukuphefumla.
