Embonini yokuthunga insimbi kanye nokuthunga, ukuthembeka kwezingxenye eziphikisayo kuthinta ngqo ukusebenza kahle kokukhiqiza, ukuphepha, kanye nekhwalithi yomkhiqizo. Phakathi kwalezi zingxenye ezibalulekile,Izitini Zokuthela Ngaphansizibalulekile, zenzelwe ukumelana namazinga okushisa aphezulu, izinsimbi ezincibilikisiwe ezigqwalayo, kanye nokushaqeka kokushisa ngenkathi kuqinisekiswa ukugeleza kwensimbi okubushelelezi nokulawulwayo. Kusukela ekukhiqizweni kwensimbi kuya ekubunjweni kwe-alloy ngokunemba, ukusetshenziswa kwazo okuguquguqukayo kuzenza zibe yitshe lesisekelo lemisebenzi yesimanje yokwenziwa kwensimbi. Ngezansi umbono oningiliziwe wokusetshenziswa kwazo okubalulekile kanye nenani lezimboni.
1. Isicelo Esiyinhloko: Insimbi Nokuphonswa Kwe-Alloy
Ukusetshenziswa okuyinhloko kweIzitini Zokuthela Ngaphansikusezinqubweni zokubumba insimbi ne-alloy. Njengezingxenye ezibalulekile zezinhlelo zokubumba i-ladle, zibeka imigqa ye-ladle, zakha ama-nozzle okuthulula, izitini zesihlalo, kanye nezitini ze-sleeve. Iziteshi zazo zokugeleza eziklanywe kahle zivumela ukusatshalaliswa kwensimbi encibilikisiwe efanayo, engenawo ama-turbulence, okuyisici esibalulekile ekunciphiseni amaphutha okubumba njenge-porosity, i-inclusions, kanye nokungahambi kahle kwendawo.
Ezindaweni zokugaya insimbi, lezi zitini zidlala indima ebalulekile ezinhlelweni zokuthela phansi, zigcina ubuqotho bezitsha zokubhaka kanye neziteshi ngesikhathi sokudluliselwa kwensimbi encibilikisiwe.Izinhlobo ezisekelwe ku-alumina ephezulu kanye ne-mulliteinikeza ukumelana okumangalisayo nensimbi encibilikisiwe kanye nokugqwala kwe-slag, yandisa impilo yensika futhi inciphise isikhathi sokungasebenzi. Ngokusebenzisa i-alloy casting—lapho ukwakheka kwamakhemikhali okunembile kanye nokulawula izinga lokushisa kungaxoxiswana ngakho—Izitini Zokuthela Ngaphansiqinisekisa ukuthululwa okuqhubekayo, ukuvimbela ukuhlukaniswa kwe-alloy nokuthuthukisa ikhwalithi yomkhiqizo wokugcina.
2. Ukufakwa Kwesithando Somlilo Se-Foundry kanye Nokufakwa Kokushisa
Ngale kwezinhlelo zokuthulula,Izitini Zokuthela Ngaphansizisetshenziswa kabanzi njengezinto zokwakha ulwelwesi lwezitofu ze-foundry, izitofu ze-arc, kanye nezitofu zokungenisa. Njengoba zizinzile kakhulu ekushiseni (zimelana namazinga okushisa angaphezu kuka-1700°C), zivikela ngempumelelo ingaphakathi lesitofu, zinciphise ukulahleka kokushisa futhi zithuthukise ukusebenza kahle kwamandla. Lokhu kuvikela ukushisa akugcini nje ngokunciphisa izindleko zokusebenza kodwa futhi kudala indawo yokushisa ezinzile, ebalulekile ekuncibilikisweni nasekuhluzweni kwensimbi okufanayo.
Ukumelana kwazo nokushaqeka kokushisa kuvimbela ukuqhekeka kanye nomonakalo wesakhiwo ngenxa yokushintshashintsha kwezinga lokushisa okusheshayo, kuqinisekisa impilo yesevisi yesithando somlilo isikhathi eside kanye nokunciphisa ukuvalwa kokugcinwa. Ekwenzeni insimbi ngokuguqula, isibonelo, lezi zitini zisekela imisebenzi ephumelelayo yokushaya phansi ngokugcina ukuzinza kokugeleza kwegesi kanye nokumelana nokuguguleka okuvela ensimbini encibilikisiwe enesivinini esikhulu.
3. Ukusakaza Okunembile Kwezimboni Ezisezingeni Eliphezulu
Imikhakha yokusakaza ngokunembile—kufaka phakathi ukukhiqizwa kwezindiza, izimoto, kanye namadivayisi ezokwelapha—ithembele kakhuluIzitini Zokuthela Ngaphansiukuze kugeleze insimbi encibilikisiwe elawulwayo nenembile. Ekubunjweni kwezimali (ukukhishwa kwe-wax elahlekile), balawula amazinga okugeleza abe yizibunjwa eziyinkimbinkimbi, baqinisekise ukugcwaliswa okugcwele ngaphandle kokulimaza izakhiwo zesikhunta ezibucayi.
I-porosity efanayo yekhwalithi ephezuluIzitini Zokuthela Ngaphansifuthi kusiza ekukhipheni igesi encibilikisiwe, ukususa ukungcola kanye namabhamuza omoya abeka engcupheni izakhiwo zemishini zezingxenye ezinembile. Ezingxenyeni ezibalulekile njengezinjini zezimoto noma izingxenye zezindiza ezidinga amandla aphezulu nokuthembeka, lokhu kunemba kwenza lezi zitini zibe yingxenye engenakuphikiswa yochungechunge lokukhiqiza.
4. Izixazululo Ezenziwe Ngokwezifiso Zezidingo Ezihlukahlukene
Inzuzo ebalulekile yeIzitini Zokuthela Ngaphansiukukwazi kwazo ukuzivumelanisa nezidingo zezimboni ezahlukahlukene. Abakhiqizi banikeza izinketho ezenziwe ngokwezifiso ngokwesimo, usayizi, kanye nokwakheka kwezinto ukuze kuhambisane nezinqubo ezithile: Izitini ezenziwe ngobumba zisebenza kahle ekubunjweni okungenansimbi okuphakathi nendawo (i-aluminium, ithusi); izitini ze-alumina ephezulu zisebenza kahle ekubunjweni kwe-ferrous okuphakathi nendawo okunokumelana nokugqwala okuphezulu; izitini ze-mullite zilungele izindawo ezinzima, ezivame ukuba ne-slag njengezitsha zokwenza insimbi, ngenxa yesakhiwo sazo esiqinile esivimbela ukungena kwensimbi encibilikisiwe.
Kungani Kufanele Ukhethe Izitini Ezithululwa Ngaphansi Ezisezingeni Eliphezulu?
Ukutshala imali ezitini ezisezingeni eliphezulu zokuthela i-Bottom Pouring Bricks kuholela ekuthuthukisweni kwekhwalithi yokubumba, ukuncipha kwesikhathi sokungasebenzi, kanye nokwehla kwezindleko zesikhathi eside.. Ukuqina kwazo kanye nokuqina kokusebenza kwazo kuqinisekisa umkhiqizo oqhubekayo, kuyilapho ukuguquguquka kwazo kusekela izinqubo eziningi zokwenziwa kwensimbi. Kungakhathaliseki ukuthi kukhiqizwa insimbi enkulu noma kukhiqizwa izingxenye ezinembile, lezi zitini ziletha ukuthembeka nokusebenza kahle okudingwa yizinto zokwenziwa kwensimbi zanamuhla.
Okwenziwe ngokwezifisoIsitini Sokuthela Esingezansiizixazululo ezifanela izidingo zakho zezimboni ezithile, xhumana nethimba lethu lochwepheshe abaphikisayo namuhla. Sinikeza imikhiqizo esebenza kahle kakhulu eyenzelwe ukuphakamisa imisebenzi yakho yokusakaza.
