Kumakhonkco ahlukeneyo emveliso yamashishini,ukuphosa izitena zentsimbi, njengezinto eziphambili ezineempawu ezikhethekileyo, zidlala indima engenakuthathelwa indawo. Ngokuxhathisa kwabo kubushushu obuphezulu, ukuxhathisa umhlwa kunye nezinye iimpawu, ziye zasetyenziswa ngokubanzi kwiindawo ezininzi, zibonelela ngesiqinisekiso esibalulekileyo senkqubela phambili egudileyo yemveliso yemizi-mveliso.
Indima ephambili kwi-Metallurgical Casting
Kwishishini lokuphosa i-metallurgical, ukuphosa izitena zentsimbi zizinto eziphambili eziyimfuneko. Injongo yabo ephambili kukusebenza njengomjelo wentsimbi etyhidiweyo ukuba ihambe ukusuka kwi-ladle ukuya kwi-ingot mold kwinkqubo yokuphosa engezantsi. Ngokukodwa, ukuphosa izitena zetsimbi zakhiwe kwi-grooves ye-ingot casting base plate, enye isiphelo esiqhagamshelwe kwisitena sokusabalalisa intsimbi kunye nesinye isiphelo esiqhagamshelwe kwi-ingot mold, eyenza indlela ephambili yokuhamba kwentsimbi etyhidiweyo. Ke ngoko, zihlala zibizwa ngokuba "zitena ze-tundish" ngabangaphakathi
Ngexesha lenkqubo yokugalela intsimbi enyibilikisiweyo, ubushushu bentsimbi enyibilikisiweyo yobushushu obuphezulu buphezulu kakhulu, buhlala bufikelela kumawaka edigri kaCelsius, nto leyo ibeka iimfuno eziphakamileyo kakhulu kubushushu obuphezulu bokumelana nezitena zentsimbi. Ngelo xesha, insimbi etyhidiweyo iya kuba nefuthe elinamandla kunye nokuhlahlela kumzimba wezitena ngexesha lokuhamba, kunye nentsimbi etyhidiweyo ngokwayo iya kuba neempendulo ezithile zeekhemikhali kunye nomzimba wezitena. Izitena zetsimbi ezikumgangatho ophezulu ziyakwazi ukumelana nolu vavanyo kwaye ziqinisekise ukuhamba kakuhle kwentsimbi etyhidiweyo. Umngxuma wayo wangaphakathi ugudile, onokuthi unciphise ngokufanelekileyo ukuchasana xa isinyithi esityhidiweyo sihamba, sigweme ukuhamba kwesiphithiphithi ngexesha lokuhamba kwensimbi etyhidiweyo, ngokunciphisa isizukulwana seziphene ezifana namaqamza kunye nokufakwa kwi-ingot, kunye nokuphucula umgangatho we-ingot. Nokuba kukuphosa okusicaba kwentsimbi engatyiwayo, intsimbi yealloyi okanye intsimbi eqhelekileyo yekhabhoni, izitena zentsimbi ezigalelweyo zinokulungelelaniswa kakuhle ukunika inkxaso ezinzileyo yokuphosa iintlobo ezahlukeneyo zentsimbi.
Isixhobo esiBalulekileyo seLining kwii-Industrial Furnaces
Izitofu zemizi-mveliso zizixhobo eziphambili kwiinkqubo ezininzi zemveliso yemizi-mveliso, ezifana nezitofu eziqhumayo kunye nezitovu ezitshisayo kwishishini lentsimbi kunye nentsimbi, kunye neziko lokuphendula kwishishini lemichiza. Ezi ziko zihlala kufuneka zisebenze kwindawo ezinobushushu obuphezulu, kwaye imeko yangaphakathi ilukhuni kakhulu. Izitena zentsimbi ezisalayo, ezinokumelana nobushushu obuphezulu kunye nokumelana nomhlwa, ziye zaba lolona khetho lufanelekileyo kumbane weziko lemizi-mveliso.
Ukusebenzisa izitena zetsimbi ezigayiweyo njengoko i-lining of furneces ye-industrial inokumelana ngokufanelekileyo nokubhaka okuphezulu kweqondo lokushisa kwiziko kunye nokukhukuliseka kweegesi ezahlukeneyo ezinobungozi kunye nolwelo. Inokukhusela isakhiwo segobolondo sesithando somlilo, ugweme i-deformation kunye nokulimala komzimba wesithando somlilo ngenxa yokushisa okuphezulu, kunye nokwandisa ubomi benkonzo yesithando somlilo. Ngexesha elifanayo, ukuphosa izitena zetsimbi kunokusebenza kakuhle kwe-thermal insulation, enokunciphisa ilahleko yobushushu kwiziko, ukuphucula ukusetyenziswa kwamandla, kunye nokunciphisa ukusetyenziswa kwamandla okuvelisa. Kwamanye amaziko afuna ulawulo oluchanekileyo lobushushu, ukusebenza okuzinzile kokuphosa izitena zentsimbi kunokunceda ukugcina ukufana kweqondo lobushushu kwiziko, ukuqinisekisa ukuzinza kwenkqubo yokuvelisa, kwaye ngaloo ndlela kuphuculwe umgangatho wemveliso.
Isicelo soKhuseleko kwiiNkqubo zeMibhobho eziKhethekileyo
Kweminye imveliso yemizi-mveliso, kukho iinkqubo ezikhethekileyo zemibhobho yokuthutha i-high-temperature kunye ne-high-pressure media (njenge-steam-high-temperature, isinyithi esinyibilikisiweyo, njl.). Le mibhobho ikwimeko enzima yokusebenza ixesha elide kwaye ithanda ukukhuhla, ukubola kunye nomonakalo wobushushu obuphezulu ngamajelo eendaba, nto leyo echaphazela ukhuseleko kunye nobomi benkonzo yemibhobho.
Ukuphosa izitena zetsimbi zingasetyenziselwa ukukhusela iindawo eziphambili zezi nkqubo zemibhobho ekhethekileyo. Ngokwakha izitena zetsimbi zetsimbi kwiindawo ezithile ngaphakathi okanye ngaphandle kombhobho, umqobo wokukhusela oqinileyo unokubunjwa ukuchasana nempembelelo ethe ngqo kunye nokukhukuliseka kwendawo ephakathi kumbhobho. Ngokukodwa kwiindawo ezijikayo kunye ne-interfaces yombhobho, okulungele ukugqoka kunye nokubola, umphumo wokukhusela wokuphosa izitena zetsimbi kubonakala ngakumbi. Inokunciphisa ngokufanelekileyo izinga lokuguga kombhobho, inciphise umngcipheko wokuvuza kwemibhobho, iqinisekise ukusebenza ngokukhuselekileyo nokuzinzileyo kwenkqubo yemibhobho, ukunciphisa ukuphazamiseka kwemveliso okubangelwa kukugcinwa kwemibhobho, nokuphucula ukusebenza kakuhle kwemveliso.
Ukuphosa izitena zetsimbi, kunye neempawu zazo ezikhethekileyo, zinezicelo ezibalulekileyo kwi-metallurgical casting, iziko loshishino, iinkqubo zemibhobho ekhethekileyo kunye nezinye iindawo. Ngophuhliso oluqhubekayo lweteknoloji yokuvelisa imveliso, iimfuno zokusebenza kwezitena zetsimbi zikhula rhoqo. Kwixesha elizayo, uluhlu lwabo lwesicelo kulindeleke ukuba lwandise ngakumbi, lubonelele ngenkxaso yezinto eziphathekayo ezithembekileyo kwiinkalo ezininzi zoshishino. Ukuba ujonge izinto ezifanelekileyo zokumelana nobushushu obuphezulu kunye ne-corrosion-resistant yeeprojekthi ezinxulumene nemizi-mveliso, ukwenza izitena zentsimbi ngokungathandabuzekiyo lukhetho olukumgangatho ophezulu ofanele ukuqwalaselwa.
