Yintoni umahluko phakathiIshushu EqengqelekayokwayeIityhubhu zentsimbi eziqengqelekayo ezibandayo?
Nangona zombini ezi mveliso zisetyenziswa ekwenzeni intsimbi, umahluko ophambili uvela kwinkqubo yokwenza.
Kwimveliso yeetyhubhu zentsimbi ezakhiweyo, "i-hot rolled" idla ngokunxulunyaniswa neendawo ezingenanto ezigqityiweyo zishushu, ngelixa iityhubhu ezininzi zesikwere nezingxande ziveliswa ngokwenza okubandayo kwiikhoyili zentsimbi ezishushu ezigobileyo.
Indlela yokuvelisa ichaphazela ngokuthe ngqo imeko yomphezulu wetyhubhu, ukuchaneka kobukhulu bayo, uxinzelelo olushiyekileyo, kunye nokusebenza kokugqibela kokusetyenziswa kwayo.
Inkqubo Yokuvelisa: Indlela Ezenziwa Ngayo Iityhubhu Eziqengqelekayo Nezibandayo
Iityhubhu zentsimbi eziqengqelekayo ezishushu
Iityhubhu zentsimbi ezigoqwe ngobushushu zenziwa kumaqondo obushushu angaphezulu kobushushu bokuphinda kusetyenziswe isinyithi, ngesiqhelo ngaphezulu kwama-926°C.
Kumaqondo obushushu aphezulu, intsimbi iba thambile kwaye kube lula ukuyiguqula, nto leyo evumela abavelisi ukuba bavelise amacandelo amakhulu anozinzo oluhle kwisakhiwo.
Emva kokwakheka, intsimbi iphola ngokwendalo kubushushu begumbi. Inkqubo yokuphola ecothayo inceda ekunciphiseni uxinzelelo olushiyekileyo kwaye inika amandla okusebenza kakuhle kunye nokusebenza kakuhle kokwenziwa.
Ukuvelisa Inkqubo
Iityhubhu zentsimbi ezenziwe ngobandayo
Iityhubhu zentsimbi ezenziwe ngobushushu obubandayo ziveliswa kubushushu begumbi ngokusebenzisa iinkqubo zokusebenza ezibandayo.
