Malunga eshushu rolled
Xa kuthelekiswa nokuqengqeleka okubandayo, ukuqengqeleka okushushu kuqengqeleka ngaphantsi kweqondo lobushushu bekristale, kwaye ukuqengqeleka okushushu kuqengqeleka ngaphezulu kobushushu becrystallization.
Ikwaziwa njenge hot plate, hot rolled plate.I-slab-rolled-rolled slab yenziwe nge-slab eqhubekayo yokuphosa okanye i-pre-rolled slab njengento ekrwada, efudunyezwa kwiziko lokufudumeza elinyukayo, ihlanjululwe ngamanzi anoxinzelelo oluphezulu, ize ingene kwi-roll rolling mill.Izinto ezijikelezayo zingena kwi-mill yokugqiba ukulawula ikhompyutha emva kokusika intloko kunye nomsila.Emva kokuqengqeleka, emva kokuqengqeleka kokugqibela, ipholiswa yi-laminar flow (isantya sokupholisa esilawulwa yikhompyuter, kwaye idityaniswe kwiikhoyili ezithe tye ngecoiler.
Inzuzo
(1) I-Hot rolling inokunciphisa kakhulu ukusetyenziswa kwamandla kunye nokunciphisa iindleko.Ngexesha elitshisayo, isinyithi sineplastiki ephezulu kunye nokuchasana kwe-deformation ephantsi, okunciphisa kakhulu ukusetyenziswa kwamandla okuguqulwa kwesinyithi.
(2) I-Hot rolling inokuphucula iimpawu zokucubungula isinyithi kunye ne-alloys.Nangona i-as-cast coarse grains iphukile, iintanda ziphiliswa ngokucacileyo, iziphene zokuphosa ziyancitshiswa okanye zipheliswe, kwaye isakhiwo se-as-cast siguqulwa sibe sisakhiwo esiphosakeleyo, esiphucula ukusebenza kwe-alloy.
(3) I-Hot rolling ngokuqhelekileyo ithatha i-ingots ezinkulu zetsimbi kunye nemilinganiselo yokunciphisa i-rolling enkulu, engaphuculi kuphela ukusebenza kwemveliso, kodwa idala iimeko zokunyusa isantya kunye nokuqonda ukuqhubeka kunye nokuzenzekelayo kwenkqubo yokuguqa.
Ukuhlelwa
Ipleyiti yentsimbi eshushu yahlulwe yaba yintsimbi yolwakhiwo, intsimbi ephantsi yekhabhoni kunye nentsimbi yebhotile.Ishiti elishushu eliqengqelekayo linobulukhuni obuphantsi, ukusetyenzwa lula kunye ne-ductility elungileyo.Amashiti entsimbi ashushu athambileyo anamandla aphantsi kunye nomgangatho ophantsi womphezulu (i-oxidation ephantsi / ukugqiba ukugqiba), kodwa iplastiki elungileyo.Ngokubanzi, ngamacwecwe aphakathi kunye nobunzima kunye neepleyiti eziqengqelekayo ezibandayo ezinamandla amakhulu, ubunzima obuphezulu kunye nokugqiba okuphezulu komhlaba.Ziziipleyiti ezibhityileyo ngokuqhelekileyo kwaye zinokusetyenziswa njengeepleyiti zesitampu.
Imilinganiselo
Ubungakanani bentsimbi yentsimbi kufuneka bufezekise iimfuno zetafile "Imilinganiselo kunye neNkcazo yeePlati ze-Hot-Rolled Steel (ekhutshwe kwi-GB / T709-2006)".
Ububanzi bentsimbi yentsimbi bunokuba naluphi na ubungakanani be-50mm okanye i-multiple ye-10mm, kwaye ubude beplate yensimbi bunokuba naluphi na ubungakanani be-100mm okanye i-multiple ye-50mm, kodwa ubude obuncinci beplate yensimbi enobunzima obungaphantsi. ngaphezu okanye ukulingana nobukhulu bulingana ne-4mm kwaye ingabi ngaphantsi kwe-1.2m, kwaye ubukhulu bukhulu kune-4mm.Ubude obuncinci bentsimbi yensimbi ayikho ngaphantsi kwe-2m.Ngokweemfuno, ubukhulu beplate yensimbi bungaphantsi kwe-30mm, kwaye ikhefu lobunzima linokuba ngu-0.5mm.Ngokweemfuno, emva kokuxoxisana phakathi komthengisi kunye nomthengi, ezinye iinkcukacha zeeplate zetsimbi kunye neentambo zetsimbi zinokunikezelwa.
