Yenziwa njani iStainless Steel?

Intsimbi engagqwaliyo yenye yezona zinto zisebenziseka lula nezisetyenziswa kakhulu kumashishini anamhlanje. Yaziwa ngamandla ayo, ukumelana nokugqwala, kunye nokuthandeka kwayo, idlala indima ebalulekileyo ekwakheni, ekuthuthweni, kwizixhobo zonyango, kwimpahla yasekhaya, nakwamanye amacandelo amaninzi. Kodwa yenziwa njani intsimbi engagqwaliyo?

Inkqubo yokuvelisa intsimbi engagqwaliyo yindibaniselwano yesinyithi, ikhemistri, kunye nokuchaneka kobunjineli. Ukusuka ekukhethweni kwezinto eziluhlaza ukuya ekugqityweni kokugqibela, inyathelo ngalinye liqinisekisa ukuba intsimbi engagqwaliyo ihlangabezana nokusebenza okungqongqo kunye nemigangatho yomgangatho. Eli nqaku lihlola inkqubo epheleleyo yokuveliswa kwentsimbi engagqwaliyo, kubandakanya izinto eziluhlaza, ukucocwa, ukwenziwa, kunye nezigaba zokugqitywa.

Izinto ezisetyenziswa kwimveliso yentsimbi engagqwaliyo

Intsimbi engagqwali yingxubevange eyenziwe ngokuyintlokoisinyithi, i-chromium, kunye ne-nickel, kunye nezinye izinto ezongeziweyo ukuphucula iipropati ezithile.

  • Igoqo lentsimbi: Into esisiseko yokwenziwa kwentsimbi.

  • I-Chromium: Yongezwa ubuncinane nge-10.5 ekhulwini ukuze inike uxhathiso lokugqwala ngokwenza umaleko we-oxide okhuselayo.

  • I-Nickel: Iphucula ukuqina, ukuqina, kunye nokumelana nokugqwala.

  • Ezinye Izinto: Ezifana ne-manganese, i-silicon, i-nitrogen, okanye i-titanium, kuxhomekeke kudidi.

Ezi zinto ziluhlaza zilinganiswa ngononophelo kwaye zidityaniswe ukuvelisa uhlobo lwentsimbi engagqwaliyo olufunekayo.

Inyathelo 1: Ukunyibilikisa nokuCoca

Inqanaba lokuqala lemveliso yentsimbi engagqwaliyo liqala ngexeshaisithando sombane se-arc (EAF).

  1. Ukutshaja isithando somlilo: Isinyithi esilahliweyo kunye nezinto ezikrwada zifakwa esitovini. Ukusebenzisa intsimbi esetyenzisiweyo kunciphisa iindleko kunye nefuthe kwindalo esingqongileyo.

  2. Ukunyibilika: Ii-arcs zombane zifudumeza izinto ukuya kumaqondo obushushu angaphezulu kwe-1500°C, zinyibilikisa iintsimbi zibe yimeko enyibilikisiweyo.

  3. Ukucocwa: Ngexesha lokunyibilika, ukungcola okufana nesalfure kunye nekhabhoni egqithisileyo kuyasuswa. Izinto ezixutywayo ezifana ne-chromium kunye ne-nickel zongezwa ngokuchanekileyo ukuze kufezekiswe ukwakheka kweekhemikhali okufunekayo.

Isiphumo kukuba ibhafu yentsimbi engenasici enyibilikisiweyo ilungele ukucutshungulwa ngakumbi.

Inyathelo lesi-2: Ukuphosa

Nje ukuba icocekile, intsimbi enyibilikisiweyo ibunjwa ngendlelaukuphoswa okuqhubekayo or ukuphoswa kwe-ingot.

  • Ukuphosa Okuqhubekayo: Intsimbi engatyiwayo enyibilikisiweyo igalelwa kwimoldi epholileyo, iqina ibe ziimo ezigqityiweyo njengeeslabhi, iibhilethi, okanye iintyatyambo.

  • Ukuphosa i-Ingot: Isetyenziselwa iiklasi zentsimbi engagqwaliyo ekhethekileyo, apho intsimbi enyibilikisiweyo iphoswa kwiingots ezinkulu ukuze ibunjwe kamva.

Eli nqanaba lichaza uhlobo lokuqala lwentsimbi engagqwaliyo ngaphambi kokuba iqengqeleke okanye iqiniswe.

Inyathelo lesi-3: Ukuyila

Iimveliso ezigqityiweyo ngokwenziwa kwesamente emva koko zitshiswa okanye zenziwe ngendlela esebenzisekayo.

  • Ukuqengqeleka OkushushuIislabs ziyafudunyezwa kwakhona zize zisongwe zibe ziipleyiti, amaphepha, okanye imicu.

  • UkubumbaIibhilethi okanye ii-ingots zibethelelwa ngesando okanye zicinezelwe kwiibhari, iintonga, okanye iimilo ezenziwe ngokwezifiso.

  • Umzobo Weengcingo: Iingcingo zentsimbi engatyiwayo ziveliswa ngokutsala iintonga kwiidayi.

Eli nqanaba lokwakheka limisela ijiyometri esisiseko yeemveliso zentsimbi engagqwaliyo.
