Zenziwa njani imicu yentsimbi engatyiwayo?

Iteyiphu yentsimbi luhlobo lwemathiriyeli yetsimbi esetyenziswa ngokubanzi kwimimandla eyahlukeneyo yemizi-mveliso, eyaziwa ngokugqwesa kwayo kokugqwesa ukugqwala, iipropathi zobushushu obuphezulu kunye namandla omatshini. Ke yenziwa njani le nto ingundoqo? Oku kulandelayo kuya kwazisa ngokufutshane inkqubo yokwenziwa kwebhanti yensimbi engenasici.

 

Ukulungiswa kwemathiriyeli ekrwada

Ukuveliswa kwamabhanti ensimbi engenasici kuqala ngokukhethwa kwezinto ezifanelekileyo zekrwada. Ngokuqhelekileyo, amacandelo aphambili ensimbi engenasici yintsimbi, i-chromium kunye ne-nickel, apho umxholo we-chromium ubuncinci i-10.5%, eyenza insimbi engenasici inokumelana ne-corrosion. Ukongeza kwezi zixhobo eziphambili, ezinye izinto zingongezwa ukuphucula iimpawu zabo, ezifana nekhabhoni, i-manganese, i-silicon, i-molybdenum, ithusi, njl.

 

Ngena kwinqanaba lokunyibilika

Kwinqanaba lokunyibilika, izinto ezixubileyo eziluhlaza zifakwe kwisithando sombane se-arc okanye isithando somlilo sokunyuswa. Iqondo lobushushu ngaphakathi kwiziko lidla ngokufikelela malunga ne-1600 ngokukaCelsius. Intsimbi yolwelo etyhidiweyo iyacocwa ukuze isuse ukungcola neegesi kuyo.

 

Galela kumatshini wokuphosa oqhubekayo

I-liquid stainless steel ithululelwa kumatshini oqhubekayo wokuphosa, kwaye i-strip yensimbi engenasici yenziwa ngenkqubo eqhubekayo yokuphosa. Kule nkqubo, intsimbi engamanzi engamanzi iphoswa ngokuqhubekayo kumngundo ojikelezayo ukwenza umcu ongenanto wobunzima obuthile. Izinga lokupholisa kunye nokulawulwa kweqondo lokushisa kwesikhunta kunempembelelo ebalulekileyo kumgangatho kunye nokusebenza komcu.

 

Ngena kwinqanaba elishushu lokuqengqeleka

I-billet ishushu igqitywe yi-hot rolling mill ukwenza ipleyiti yentsimbi kunye nobukhulu obuthile kunye nobubanzi. Ngexesha lokutshisa okutshisayo, ipleyiti yensimbi ixhomekeke kwi-multiple rolling kunye nokulungiswa kweqondo lokushisa ukufumana ubungakanani obufunwayo kunye neempawu.

 

Inqanaba lokukha

Kule nkqubo, umgca wensimbi ongenasici uxutywe kwisisombululo esine-acidic ukususa i-oxides yomhlaba kunye nokungcola. Umphezulu womgca wensimbi engenasici emva kokukhetha ulula, obonelela ngesiseko esihle sokuqengqeleka okubandayo okulandelayo kunye nonyango lomphezulu.

 

Inqanaba elibandayo lokuqengqeleka

Kweli nqanaba, umcu wentsimbi ecocekileyo uqengqeleka ngakumbi kwilitye elibandayo ukuze ulungelelanise ngakumbi ubungqingqwa kunye nokuba mcaba. Inkqubo yokuqengqeleka ebandayo inokuphucula umgangatho womphezulu kunye nokuchaneka komgca wensimbi engenasici.

 

Inqanaba lokugqibela

Emva koluhlu lweenkqubo zonyango emva kokunyanga, ukupholisa kunye nokusika, umgca wensimbi ongenasiphelo ugqibezela inkqubo yokuvelisa. Inkqubo ye-annealing inokuphelisa uxinzelelo ngaphakathi kwintsimbi yensimbi engenasici, iphucule iplastiki yayo kunye nokuqina; Inkqubo yokupolisha inokwenza umphezulu womgca wentsimbi egudileyo ngakumbi kwaye uqaqambe; Inkqubo yokusika inqumla umgca wensimbi engenasici kubude obufunwayo kunye nobubanzi njengoko kufuneka.

 

Isishwankathelo

Inkqubo yokwenziwa komgca wensimbi engenasici ibandakanya ukulungiswa kwezinto ezikrwada, ukunyibilika, ukuphoswa ngokuqhubekayo, ukuqengqeleka okushushu, ukucolwa, ukuqengqeleka okubandayo kunye nonyango lwasemva konyango kunye namanye amakhonkco. Inyathelo ngalinye lifuna ulawulo oluchanekileyo lweeparamitha zenkqubo kunye nemigangatho yomgangatho wokuqinisekisa ukuba imveliso yokugqibela ihlangabezana neemfuno zomgangatho. Ukusetyenziswa okubanzi kweentambo zensimbi ezingenasici ngenxa yokumelana nokugqwesa okugqwesileyo kunye neempawu zemishini, kwaye ukulawulwa kakuhle kwenkqubo yokuvelisa kuyisitshixo ekufezekiseni ezi zakhiwo.
