Iindaba

Kwishishini lokubumba isinyithi kunye nokuthunga, ukuthembeka kwezinto ezichaseneyo kuchaphazela ngokuthe ngqo ukusebenza kakuhle kwemveliso, ukhuseleko, kunye nomgangatho wemveliso. Phakathi kwezi zinto zibalulekileyo,Izitena zokugalela ezantsiazinamsebenzi, zenzelwe ukumelana nobushushu obugqithisileyo, iintsimbi ezinyibilikisiweyo ezitshatyalaliswayo, kunye nokutshayiswa kobushushu ngelixa ziqinisekisa ukuhamba kwesinyithi okugudileyo nokulawulwayo. Ukusuka kwimveliso yentsimbi ukuya ekubunjweni kwe-alloy ngokuchanekileyo, usetyenziso lwazo oluguquguqukayo luzenza zibe yintsika yemisebenzi yanamhlanje yokwenziwa kwezinto zokubumba. Apha ngezantsi kukho isishwankathelo esineenkcukacha zokusetyenziswa kwazo okubalulekileyo kunye nexabiso lemizi-mveliso.

1. Isicelo esingundoqo: Intsimbi kunye ne-Alloy Casting

Ukusetyenziswa okuphambili kweIzitena zokugalela ezantsiIkwiinkqubo zokuphosa intsimbi kunye ne-alloy. Njengeenxalenye ezibalulekileyo zeenkqubo zokuphosa i-ladle, zibeka ii-ladle, zenze i-nozzles zokuthulula, izitena zesihlalo, kunye nezitena zemikhono. Iitshaneli zazo zokuhamba ezilungiselelwe ngokuchanekileyo zivumela ukusasazwa kwesinyithi esinyibilikisiweyo ngokulinganayo, okungenaziphazamiso, into ebalulekileyo ekunciphiseni iziphene zokuphosa ezifana nokuqhekeka, ukufakwa kwezinto, kunye nokungahambi kakuhle komphezulu.

Kwiindawo zokugaya isinyithi, ezi zitena zidlala indima ebalulekileyo kwiinkqubo zokugalela ezantsi, zigcina ukuthembeka kwezinto ezisetyenziswa ekutshiseni kunye nemijelo ngexesha lokudluliselwa kwesinyithi esinyibilikisiweyo.Iindidi ezisekelwe kwi-alumina ephezulu kunye ne-mullitezibonelela ngokumelana okugqwesileyo nentsimbi enyibilikisiweyo kunye nokugqwala kwe-slag, zandisa ubomi benkonzo yeladle kwaye zinciphisa ixesha lokungasebenzi. Kwi-alloy casting—apho ukwakheka kweekhemikhali ngokuchanekileyo kunye nolawulo lobushushu kungaxoxiswana ngako—Izitena zokugalela ezantsiqinisekisa ukuthululwa rhoqo, ukuthintela ukwahlulwahlulwa kwe-alloy kunye nokuphucula umgangatho wemveliso yokugqibela.

2. I-Foundry Furnace Lining kunye ne-Thermal Insulation

Ngaphaya kweenkqubo zokuthulula,Izitena zokugalela ezantsizisetyenziswa kakhulu njengezinto zokubopha iifeni ezisisiseko, iifeni ezisetyenziswa kwi-arc, kunye neefeni ezisetyenziswa kwi-induction. Ngozinzo oluphezulu lobushushu (ukumelana namaqondo obushushu angaphezu kwe-1700°C), ziyayigquma ngokufanelekileyo ingaphakathi lefeni, zinciphisa ukulahleka kobushushu kwaye ziphucule ukusebenza kakuhle kwamandla. Olu gquma lushushu alugcini nje ngokunciphisa iindleko zokusebenza kodwa lukwadala imeko-bume yokufudumeza ezinzileyo, ebalulekileyo ekunyibilikiseni nasekucocweni kwesinyithi ngokulinganayo.

Ukuxhathisa kwazo ukutshayiswa bubushushu kuthintela ukuqhekeka kunye nomonakalo wesakhiwo ngenxa yokutshintshatshintsha kobushushu ngokukhawuleza, kuqinisekisa ubomi benkonzo yesithando somlilo ixesha elide kunye nokunciphisa ukuvalwa kokugcinwa. Kwi-converter steelmaking, umzekelo, ezi zitena zixhasa imisebenzi esebenzayo yokuvuthela ezantsi ngokugcina uzinzo lokuhamba kwegesi kunye nokumelana nokukhukuliseka okuvela kwisinyithi esinyibilikisiweyo esinesantya esiphezulu.

3. Ukwenziwa kwe-Precision Casting kwi-High-End Industries

Amacandelo okulahla ngokuchanekileyo—kuquka ukwenziwa kweenqwelo-moya, iimoto, kunye nezixhobo zonyango—axhomekeke kakhulu kwiIzitena zokugalela ezantsiukuze kuhambe isinyithi esinyibilikisiweyo nesilawulwayo. Kwi-investment casting (i-lost-wax casting), balawula amazinga okuhamba kwee-molds ezintsonkothileyo, beqinisekisa ukuzaliswa ngokupheleleyo ngaphandle kokonakalisa izakhiwo ze-mold ezibuthathaka.

I-porosity efanayo yomgangatho ophezuluIzitena zokugalela ezantsiikwanceda ekukhupheni igesi kwisinyithi esinyibilikisiweyo, isuse ukungcola kunye namaqamza omoya abeka emngciphekweni iimpawu zoomatshini zezinto ezichanekileyo. Kwiindawo ezibalulekileyo ezifana neebhloko zeenjini zeemoto okanye izinto zeenqwelo moya ezifuna amandla aphezulu kunye nokuthembeka, oku kuchaneka kwenza ezi zitena zibe yinxalenye engenakutshintshwa kwikhonkco lemveliso.

4. Izisombululo ezenzelwe wena kwiimfuno ezahlukeneyo

Inzuzo ephambili yeIzitena zokugalela ezantsiyindlela ezikwaziyo ukuzivumelanisa ngayo neemfuno ezahlukeneyo zoshishino. Abavelisi banikezela ngeendlela ezenzelwe wena ngokwemilo, ubungakanani, kunye nokwakheka kwezinto ukuze zihambelane neenkqubo ezithile: Izitena ezenziwe ngodongwe zibiza kakhulu xa kusenziwa i-cast engena-ferrous kubushushu obuphakathi (i-aluminium, ubhedu); izitena ze-alumina eziphezulu zigqwesile xa kusenziwa i-cast ene-ferrous kubushushu obuphezulu kwaye zinokumelana nokugqwala okuphezulu; izitena ze-mullite zilungele iindawo ezirhabaxa, ezithandwa yi-slag ezifana neeladle zokwenza intsimbi, ngenxa yesakhiwo sazo esixineneyo esithintela ukungena kwesinyithi esinyibilikisiweyo.

Kutheni Ufanele Ukhethe Izitena Ezigalelwa Ezantsi Ezisemgangathweni Ophezulu?

Ukutyala imali kwiiBricks ezigalelwa kwiBottom Pouring premium kuthetha ukuba umgangatho wokubumba uphucukile, ixesha lokungasebenzi liyancipha, kwaye iindleko eziphantsi zexesha elide ziyancipha.Ukuqina kwazo kunye nokuzinza kokusebenza kwazo kuqinisekisa imveliso ehambelanayo, ngelixa ukuguquguquka kwazo kuxhasa uluhlu olubanzi lweenkqubo zokubumba. Nokuba zezemveliso ezinkulu zentsimbi okanye ukwenziwa kwezinto ezichanekileyo, ezi zitena zibonelela ngokuthembeka nokusebenza kakuhle okufunekayo kwiimveliso zokubumba zanamhlanje.

Yenzelwe eyenzelwe wenaIsitena Sokugalela Ezantsiizisombululo ezihambelana neemfuno zakho zoshishino, nxibelelana neqela lethu leengcali ezichasene nomthetho namhlanje. Sinikezela ngeemveliso ezisebenza kakuhle ezenzelwe ukuphucula imisebenzi yakho yokusika.
