Yintoni i-hot-rolled, yintoni i-cold-rolled, kunye nomahluko phakathi kwezi zibini?

 

1. Ukuqengqeleka okushushu
I-slabs eqhubekayo yokuphosa okanye i-slabs yokuqala ejikelezayo njengezinto eziluhlaza, ifudunyezwe linyathelo lokufudumeza isithando somlilo, i-high-pressure dephosphorization yamanzi kwi-mill roughing, i-roughing material ngokusika intloko, umsila, kwaye emva koko kwi-mill yokugqibezela, ukuphunyezwa kwe-rolling elawulwa yikhompyutha, ukuqengqeleka kokugqibela okusemva kokuba i-laminar igeleza ukupholisa umshini wokupholisa (i-computer-console) ibe yi-cooling machine. Intloko kunye nomsila we-coil yeenwele ezithe tye idla ngolwimi kunye nokumila kwe-fishtail, ubukhulu, ukuchaneka kobubanzi buhlwempuzekileyo, kukho rhoqo umphetho owenziwe ngamaza, umphetho odibeneyo, inqaba kunye nezinye iziphene. Ubunzima bayo bomthamo bunzima, ububanzi bangaphakathi bekhoyili yensimbi yi-760mm. (Ishishini lokwenza umbhobho jikelele lithanda ukusebenzisa.) Ikhoyili yeenwele ezithe ngqo ngokusika intloko, umsila, umgca wokusika kunye nokulungiswa okungaphezulu kwesinye, ukulinganisa kunye nokunye ukusetyenzwa komgca wokugqiba, kwaye emva koko ipleyiti yokusika okanye i-roll-roll, oko kukuthi: ipleyiti yentsimbi eshushu, i-flat hot roll rolling coils, i-longitudinal cut strip kunye nezinye iimveliso. Iikhoyili zokugqiba ezishushu ukuba ukucholwa ukususa ulusu lwe-oxide kunye ne-oyile kwi-coil epikiweyo eshushu. Lo mfanekiso ungezantsi ubonisa iIkhoyili eshushu esongwayo.

 

2. Ukubanda Kuqengqiwe
Iikhoyili zentsimbi ezishushu ziqengqiwe njengezinto eziluhlaza, emva kokukhetha ukususa ulusu lweoksidi kuqengqeleka olubandayo, imveliso egqityiweyo yomthamo oqinileyo, ngenxa yokuguquka okubandayo okubangelwa kukuqina okubandayo komthamo oqinileyo wamandla, ukuqina, ukuqina kunye neempawu zeplastiki eziyehlayo, ukuwohloka kokusebenza kwesitampu, kunokusetyenziswa kuphela ukuguqula amalungu. Ikhoyili eqinileyo eqengqelekayo ingasetyenziswa njengezinto ezikrwada kwiplanti yokugalela idiphu eshushu, kuba iyunithi yegalvanizing yediphu eshushu isetwa ngentambo yokufunxa. Ubunzima bekhoyili eqengqelekisiweyo buyi-6 ~ 13.5 yeetoni, ubukhulu bangaphakathi bekhoyili yi-610mm. ipleyiti eqengqelekayo ebandayo ngokubanzi, icoil kufuneka ibe yi-annealing eqhubekayo (iyunithi yeCAPL) okanye i-hooded furnace de-annealing treatment, ukuphelisa ukuqina okubandayo kunye noxinzelelo lokuqengqeleka, ukuphumeza iipropati zoomatshini ezichazwe kwizalathisi eziqhelekileyo. Umgangatho wepleyiti yentsimbi epholileyo eqengqelekayo, inkangeleko, ukuchaneka komgangatho ungcono kunepleyiti eqengqelekayo. Lo mfanekiso ulandelayo ubonisa icoil epholileyo esongwayo.

 

Umahluko ophambili phakathiebandayo eqengqelekayo vs intsimbi eshushu esongwayoilele kwitekhnoloji yokucubungula, umda wosetyenziso, iipropati zoomatshini kunye nomgangatho womphezulu, kunye nomahluko wamaxabiso. Oku kulandelayo yintshayelelo eneenkcukacha:
Iyaqhuba. I-Hot rolling yenziwa kumaqondo aphezulu, ngelixa i-cold rolling yenziwa kwiqondo lokushisa. Ukuqengqeleka okushushu kuqengqeleka ngaphezulu kobushushu becrystallization, ngelixa ukuqengqeleka okubandayo kuqengqeleka ngaphantsi kobushushu becrystallization.

 
Usetyenziso. Intsimbi eshushu egobileyo isetyenziswa ikakhulu kwizakhiwo zetsimbi okanye iinxalenye zoomatshini, kubandakanywa ukwakhiwa kwebhulorho, ngelixa intsimbi epholileyo epholileyo isetyenziswa kakhulu kushishino lweemoto okanye izixhobo ezincinci, oomatshini bokuhlamba, iifriji, njl., kubandakanywa izinto zokwakha.

 
Iimpawu zoomatshini. Iipropathi zoomatshini ezibandayo ziqhelekile kunobushushu obuqengqelekayo, kuba inkqubo yokuqengqeleka ebandayo ivelisa isiphumo sokuqina okanye ukuqina okubandayo, okukhokelela kubulukhuni obuqengqelekayo bomphezulu we sheet kunye namandla aphezulu, kodwa ukuqina kusezantsi, ngelixa iipropathi zoomatshini zeshiti eliqengqelekayo lingaphantsi kakhulu kunephepha eliqengqelekayo elibandayo, kodwa linokuqina okungcono kunye ne-ductility.

 
Umgangatho womphezulu. Umgangatho wesakhiwo somphezulu wentsimbi epholileyo uya kuba ngcono kunentsimbi eshushu egobileyo, iimveliso ezibandayo ziqina kwaye zincinci, ngelixa iimveliso ezishushu ezigobileyo zinendawo erhabaxa, enobumba.

 
Ubukhulu benkcazo. Iikhoyili ezipholileyo zihlala zincinci kuneekhoyili ezishushu ezigoqiweyo, kunye nobukhulu beekhoyili ezipholileyo ukusuka kwi-0.3 ukuya kwi-3.5 millimeters, ngelixa iikhoyili ezishushu zisuka kwi-1.2 ukuya kwi-25.4 millimeters.

Ixabiso:Ngokwesiqhelo, ukubanda kuqengqeleka kubiza kancinci kune hot rolled. Oku kungenxa yokuba ukuqengqeleka okubandayo kufuna ukusetyenziswa kwezixhobo zokusebenza ezintsonkothileyo kunye nethekhnoloji yenkqubo entsonkothileyo, kwaye unyango lokuqengqeleka olubandayo lunokufumana isiphumo esingcono sonyango lomphezulu, ngoko umgangatho weemveliso eziqengqelekayo ezibandayo uphezulu, ixabiso liphezulu ngokuhambelanayo. Ukongeza, intsimbi epholileyo eqengqelekayo kwinkqubo yokuvelisa ifuna itekhnoloji engqongqo ngakumbi kunye nobunzima bokuqhuba okuphezulu, izixhobo zemveliso, imiqulu kunye nezinye iimfuno zezixhobo ziphezulu, nto leyo eya kukhokelela ekunyukeni kweendleko zemveliso.
