Ungashintsha kanjani izitini ezikhanyisayo ekugcinweni kwemishini yokuncibilikisa ithusi

Isithando sokucwilisa i-Rotary ikakhulu silungele ukucwenga ithusi lencibilikisi encibilikisiwe, futhi izitini ezilahlayo ezilahlayo zokulungisa nokufaka ezinye esikhundleni sazo ikakhulukazi imfucumfucu yezitini ze-chrome kanye nezitini zobumba ezilahliwe. Lapho kuncibilikiswa ithusi le-blister, kuvunyelwe ukwengezwa kuphela impahla eqinile engama-20% kuya kuma-25%. Izinzuzo zayo ukulahlekelwa ukushisa okuphansi kokushisa, ukubekwa uphawu okuhle, kanye nemvelo yokusebenza ethuthukisiwe; kuncishiswe izikhathi zokulungisa, kunciphisa kakhulu ukuqaqa kanye nokufaka esikhundleni sezitini ezikhanyisayo; ukusebenza okuguquguqukayo, ukusindisa abasebenzi, namandla aphansi emisebenzi. Okubi ukuthi ukutshalwa kwemali kwemishini kuphezulu. Lokhu okulandelayo kwethula izizathu zokuthi kungani isithando sokucwilisa i-rotary sidinga ukulungiswa ngaphezulu futhi kufakwe ezinye izitini eziphikisayo.

1. Ukushisa kwesithando somlilo sokucwilisa ojikelezayo kuphakeme kune-1350 ℃ (isikhathi sokusakaza), kanti izinga lokushisa eliphakeme lingafinyelela ku-1450 ℃ (isikhathi se-oxidation). Ngoba umzimba womlilo ujikeleza, awukho umugqa we-pool oncibilikisiwe oncibilikisiwe esithandweni somlilo, futhi i-slag izogxilwa futhi incibilike. Ukuguguleka kwensimbi kucishe kubandakanye okungaphezulu kuka-2/3 kobuso bangaphakathi besithando somlilo, futhi ukulahleka kwezitini ezinenkani kulesi sigaba sokusebenza kukhulu, okudinga isikhathi sokubheka nokulungisa, kanye nezitini ezilahlayo ezilahlayo ezonakele kakhulu kufanele isuswe futhi ifakwe enye.

2. Ngenxa yokushintshana kaningi komzimba wesithando somlilo, kudingeka ukuhlolwa nokugcinwa ngesikhathi esifanele. Izitini zokukhipha imfucuza ezilimele kufanele zisuswe futhi zifakwe esikhundleni sazo, ukuze ukwakhiwa kwamatshe kanye negobolondo lensimbi kusondelene kakhulu ukukhulisa ukungqubuzana okumile phakathi kwamatshe negobolondo lesithando sensimbi. Igobolondo lesithando lizungeza ngokulandelana ukugcina ukuzinza kwamatshe.
