Ngaphambi kokuba iikhoyili zentsimbi ezishushu ezithunyelwa kwi-hot-rolling mill ziqengqeleka kwindawo yokusila ebandayo, i-pickling linyathelo lesiqhelo, kwaye itanki yokuchola kufuneka ifudunyezwe yijenereyitha yomphunga. Ukuba intsimbi yentsimbi enomlinganiselo iqengqeleke ngokuthe ngqo, kufuneka kwenzeke ezi meko zilandelayo:
(1) Ukuqengqeleka phantsi komqathango wokunciphisa okukhulu kuya kucinezela isikali se-oxide kwi-matrix yentsimbi yomtya, echaphazela umgangatho womphezulu kunye nokusetyenzwa kwephepha elipholileyo, kunye nokubangela inkunkuma;
(2) Emva kokuba isikali se-iron oxide siphulwe, singena kwinkqubo ye-emulsion yokupholisa kunye ne-lubricating, eya konakalisa izixhobo zokujikeleza kunye nokunciphisa ubomi benkonzo ye-emulsion;
(3) Ukonakalisa uburhabaxa bomphezulu buphantsi kakhulu, umxube obiza imali eninzi wokuqengqeleka obandayo.
Ngoko ke, ngaphambi kokuqengqeleka okubandayo, itanki yokuchola kufuneka ixhotyiswe ngejenereyitha yomphunga wokufudumeza ukuze isuse isikali se-oxide kumphezulu womgca kwaye isuse umcu onesiphako.
Nangona kunjalo, inkqubo yokukhetha esetyenziswayo ngoku ukususa isikali esityebileyo kumphezulu wensimbi engenasici inobushushu obuphezulu bokusebenza kunye nexesha elide lokukhetha, okukhokelela kwiindleko eziphezulu zokusetyenzwa. Ukuqala kwindlela yokufudumeza, itanki yokufudumeza ijenereyitha yomphunga isetyenziselwa ukufudumeza isisombululo, iqhosha elinye elizenzekelayo ngokupheleleyo, ukusebenza kakuhle kwe-thermal, kunokunciphisa ngokufanelekileyo amandla kunye neendleko zabasebenzi, kunye nokuqonda i-strip-rolled strip ephantsi. -inkqubo yokuhlamba .
