Njengoko kuvunywa kakuhle, ukususela ekuqulunqweni kwentsimbi, abasebenzi besinyithi baye bavelisa amabakala ahlukeneyo ensimbi ngokusekelwe kwizicelo. Oku kwenziwa ngokutshintsha inani lekhabhoni. Namhlanje, umbhobho we-carbon steel linye ilungu elidumileyo lemibhobho yensimbi kwizicelo ezahlukeneyo. Ngokuqhelekileyo, iiresiphi zensimbi zinomlinganiselo wobunzima bekhabhoni kwi-0.2% ukuya kwi-2.1%. Ukomeleza ezinye iipropathi zesiseko sentsimbi, imixube inokubandakanya ichromium, manganese, okanye iTungsten. Kodwa umlinganiselo wezi zixhobo awuchazwanga.
Umbhobho wentsimbi yeCarbon usetyenziswa rhoqo kwizicelo ezahlukeneyo kuba uhlala ixesha elide kwaye ukhuselekile. Izinto zokwakha phantsi komhlaba zinokubola kunye nezitshabalalisi. Isinyithi asiyi kubola kwaye asikwazi ukumelana nezinambuzane ezinjengeentubi. Intsimbi nayo ayifuni kunyangwa ngezithinteli, izitshabalalisi okanye iglu, ngoko ke kukhuselekile ukuyiphatha nokusebenza. Ekubeni intsimbi ayinakutsha kwaye yenza kube nzima ukuba umlilo usasazeke, kulungile ukusebenzisa umbhobho we-carbon steel kumbhobho wensimbi yesakhiwo xa ukwakhiwa kwezindlu. Izakhiwo zesakhelo sentsimbi zixhathisa ngakumbi kwiintlekele zendalo ezinjengezaqhwithi, iinkanyamba, ukubetha kwemibane, kunye neenyikima. Ngaphaya koko, umbhobho we-carbon steel uxhathisa kakhulu ukothuka kunye nokungcangcazela. Uxinzelelo lwamanzi oluguquguqukayo okanye uxinzelelo lomothuko olusuka kwihamile yamanzi lunempembelelo encinci kwintsimbi. Iimeko zezithuthi zanamhlanje zenza uxinzelelo olukhulu kwiziseko zeendlela. Umbhobho wentsimbi yekhabhoni awunakwaphuka kwezothutho nakwinkonzo, kwaye ngenxa yesi sizathu kulungile ukubeka iintsinjana zamanzi phantsi kweendlela.
Naluphi na uxinzelelo olunikiweyo, iibhobho zensimbi zekhabhoni zingenziwa zincinci kakhulu kunemibhobho eyenziwe kwezinye izinto, ngoko ke zinomthwalo omkhulu wokuthwala kunemibhobho yezinye izinto ezinobubanzi obufanayo. Kwaye amandla angenakuthelekiswa nanto emibhobho yentsimbi kwandisa ixesha elide kwaye kunciphisa imfuno yokutshintshwa kunye nokulungiswa. Abavelisi bemibhobho yentsimbi banokuvelisa imibhobho kwimilinganiselo emininzi, ukusuka ngaphantsi kwe-intshi ukuya ngaphezulu kweemitha ezintlanu. Zinokugotywa kwaye zenziwe ukuba zigobe kwaye zilingane naphi na apho zifuna ukuba khona. Amalungu, iivalve kunye nezinye izinto zokufakelwa zifumaneka ngokubanzi ngamaxabiso amahle.
Umbhobho wentsimbi othambileyo ufumaneka kwiimilo ezahlukeneyo zesakhiwo ezidityaniswe ngokulula zibe ngumbhobho okanye ityhubhu kwaye njl njl. Uninzi lwazo lulula ukwenza, lufumaneka lula, kwaye luxabisa ngaphantsi kunezinye iintsimbi ezininzi. Kwiindawo ezikhuselweyo kakuhle, ubude bobomi bombhobho wentsimbi ethambileyo buyiminyaka engama-50 ukuya kweyi-100. Ngokungafaniyo nombhobho wensimbi ophezulu wekhabhoni, umbhobho wentsimbi othambileyo unezinto zekhabhoni ezingaphantsi kwe-0.18%, ngoko olu hlobo lombhobho ludityaniswe ngokulula ngelixa ezinye iintlobo zemibhobho yentsimbi enekhabhoni ephezulu, enjengombhobho wensimbi engenasici, efuna ubuchule obukhethekileyo ukuze ngokufanelekileyo weld imathiriyeli. Namhlanje, umbhobho wentsimbi ophakathi usetyenziselwe uninzi lwemibhobho yehlabathi, kuba ayidityaniswa ngokulula nje ukuze ibekwe kwindawo ebhetyebhetye kodwa kwakhona ngandlel’ ithile inokunqanda ukuqhekeka nokwaphuka phantsi koxinzelelo.
Thumela umyalezo wakho kuthi:
