Ukuqengqeleka okubandayo kwiqondo lobushushu le-recrystallization engezantsi ebizwa ngokuba yi-coil-rolled, hot-rolled coil njengento ekrwada, iqhele ukusetyenziswa kwi-asidi pickling ukususa ulusu lwe-oxide emva kokuqengqeleka okubandayo, imveliso egqityiweyo inzima, ngenxa yomsebenzi obandayo wokuqina obangelwa yi-deformation eqhubekayo. ukuqina okubandayo okuqengqelekayo, ukomelela kokuqina, ukuqina kunye nesalathiso seplastiki sehlile, ngoko ukusebenza kwesitampu kuya kuhla, kunokusetyenziswa kuphela ukuguqulwa kwamalungu.
Ikhoyili eqinileyo inokusetyenziswa njengemathiriyeli ekrwada, idiphu eshushu ifektri eyenziwe ngamagalvanized yeyunithi yediphu eshushu yokugalela Iisetingi ngocingo olunealed.
Ubunzima bomthamo onzima kwi-20 - ngokubanzi
Iitoni ezingama-40, i-coil yensimbi, kwiqondo lobushushu begumbi lokuqengqeleka ngokuqhubekayo kwemithamo yokuchola eshushu.
Iimpawu zemveliso epholileyo: kuba akukho emva kokunyangwa kwe-anealing, ubunzima buphezulu kakhulu (
I-HRB inkulu kune-90)
, ukusebenza koomatshini kukwimeko embi, kulula kuphela ukuba ne-directivity engaphantsi kwe-90 degree bend processing.
Ilula, i-coil-rolled, isekelwe kwi-coil-rolled processing processing out, ngokubanzi ishushu iqengqeleke -

Ingqele yaqengqeleka inkqubo yokucubungula.
Ukuqengqeleka okubandayo kuphantsi kobume bokucutshungulwa yipleyiti yokuqengqeleka eshushu, ngelixa inkqubo yokucoca ukuqengqeleka kuya kwenza ubushushu beplate yentsimbi, nangona kunjalo ibizwa ngokubanda.
Ngenxa yokuba kushushu okuqengqelekayo kubanda okuqengqelekayo kwingqele eqengqelekayo ekusebenzeni koomatshini kumbi, ukuqina kuphezulu kakhulu, ngoko ke kufuneka kudlule kwi-annealing ukubuyisela iipropathi zayo zoomatshini, ngaphandle kokurhoxa kunzima.
Ikhoyili eqinileyo iqhele ukusetyenziselwa ukwenza ngaphandle kokugoba, ukuzolula iimveliso, 1.
Ngaphantsi kwe-zero ubukhulu kumacala omabini obunzima bethamsanqa okanye ukugoba okune-quadrilateral.
Ingqele iqengqeleke ngokubanzi emva konyango lwe-anealing.
Kufuneka isetyenziswe kwinkqubo ye-oyile yokuqengqeleka ebandayo ebandayo, izibonelelo zokusebenzisa i-oyile eqengqelekayo ebandayo zezi: 1, ukunciphisa ngokufanelekileyo i-coefficient ye-friction, inikeze amandla ahambelanayo, ukusetyenziswa kwamandla aphantsi, i-parameters eyanelisayo yokuqengqeleka;
2, yenza ukukhanya okuphezulu komphezulu kunye nobukhulu obufanayo bokulibaziseka kokuqengqeleka;
I-3, isiphumo esihle sokupholisa, sinokususa ngokukhawuleza ukuqengqeleka okushushu, ukukhusela i-roll kunye neqhekeza.
Ukusebenza kakuhle, akuyi kuvelisa i-oyile yokutshisa;
I-4, inomsebenzi wexesha elifutshane lokuchasana nomhlwa, unokubonelela ngokhuseleko lwexeshana lweziqwenga eziqengqelekayo.
Kushushu kwaqengqeleka kushushu (
热轧)
Ziyinxalenye yomsebenzi oshushu wenkqubo yokuqengqeleka.
I-Hot rolled high-effective yemveliso, isikali esikhulu, ukusetyenziswa kwamandla angaphantsi, ixabiso eliphantsi, iqondo eliphezulu lomatshini, i-automation, ilungele imveliso yobuninzi ngokulandelelana, yenye yeyona ndlela ibalulekileyo yoxinzelelo lwesinyithi.
Ishushu iqengqeleke ngokulungiswa kwentsimbi yokunganyangeki iphantsi kwaye iplastiki kwaye isetyenziswa ngokubanzi.
Kodwa ekubeni iqondo lobushushu eliqengqelekayo akulula ngalo xa liqengqeleka, umphezulu we-tin oxide ukhona, ukuchaneka kobungakanani bemveliso kunye noburhabaxa bomphezulu ziimveliso eziqengqelekayo ezibandayo.
Sesona sixhobo singundoqo sokusila esishushu.
Isetyenziswa kwindawo yokusila eshushu ininzi ye phyletic, kukho ezimbini zokusila, ezintathu zokusila, zokusila zokuxhela, ezine high rolling mill, Y type rolling mill, two-high skew rolling mill, three-roll skew rolling mill. , i-cross rolling mill, i-universal mill kunye nazo zonke iintlobo ze-special mill kunye nokunye.
Ngokweemfuno zemveliso yeentlobo ezahlukeneyo zeemveliso, umgangatho wemveliso, imveliso, iimeko zesayithi, njl.njl., kukho iindlela ezininzi zokusila kwi-workshop eshushu yoyilo, njengokwakheka komatshini omnye, iikholamu enye okanye ezininzi zololiwe ovulekileyo. ilungiselelo, isicwangciso sokulandelela, uhlobo lwe-rolling uhlobo, uhlobo lwe-chessboard luhonjisiwe, njl.
Inkqubo yemveliso eshushu yokuqengqeleka ngokubanzi ibandakanya ukulungiswa kwemathiriyeli ekrwada, ukufudumeza, ukuqengqeleka, ukugqiba njalo-njalo inkqubo enkulu eliqela.
I-Hot rolling ingasetyenziselwa ukugoqa i-ingot yensimbi okanye i-billet enkulu, ukuveliswa kweemveliso ezinkulu.
Njenge-ingot enkulu yokuqengqeleka kwi-70 t ngaphakathi najikelele kwi-50 t yebillet enkulu, velisa ubukhulu bepleyiti eshinyeneyo eyi-500 mm, umbhobho wentsimbi ongenamthungo we-1070 mm ububanzi, i-1200 mm x 530 MMH yentsimbi kunye neentsimbi ezingama-78 kg/m, njl.
Kwinkqubo eshushu yokuqengqeleka, iqondo lobushushu eliqengqelekisiweyo liyancipha ngokuthe ngcembe, ukuchasana ne-deformation yemathiriyeli kuyanda kancinci, ekugqibeleni akunakwenza indawo eshushu.
Ngoko ke ayibobukhulu beemveliso ezishushu ezisongiweyo zinokuba zincinci kakhulu, zinokuthi zibe yi-1 mm ishidi elishinyeneyo lokuqengqeleka, umbhobho wentsimbi oyi-20 mm ububanzi, ububanzi be-5.
0 mm ucingo, njl.
Umgca.
Ngoko ke ayibobukhulu beemveliso ezishushu ezisongiweyo zinokuba zincinci kakhulu, zinokuthi zibe yi-1 mm ishidi elishinyeneyo lokuqengqeleka, umbhobho wentsimbi oyi-20 mm ububanzi, ububanzi be-5.
0 mm ucingo, njl.
I-Hot rolling ingaba nomthamo omkhulu wemveliso, imveliso yonyaka ye-6 yezigidi ze-t ye-rough rolling mill, ukuba ikhona, kunye nomthamo wonyaka we-6 yezigidi t ezishushu eziqengqelekayo ze-DaiGangChang njl.
Iimveliso ezishushu eziqengqelekayo zinokwahlulwa ngeempawu zemilo yecandelo lomnqamlezo womtya oshushu oqengqelekayo, umbhobho wentsimbi ongenamthungo oshushu, intsimbi eshushu eshushu kunye nentsimbi ekhethekileyo eqengqelekayo iiklasi ezine.
Indlela eshushu eqengqelekayo ngokuqengqeleka yahlulwe kakhulu ibe yi-longitudinal rolling, skew rolling kunye ne-rolling.
Umahluko phakathi kwengqele eqengqelekayo kunye neshushu iqengqeleke, ebandayo iqengqeleke ibe ngamacandelo e-1 ukuvumela icandelo le-buckling lendawo, elinokuthi lisebenzise ngokupheleleyo i-bar buckling bearing umthamo emva kokuba;
I-buckling yendawo kunye nentsimbi eshushu eshushu ayivumeli icandelo lomnqamlezo.
I-2, izizathu zentsimbi eshushu egobileyo kunye nentsimbi epholileyo yoxinzelelo olushiyekileyo luhluke, ngoko ke ukuhanjiswa kwecandelo lomnqamlezo nako kunomahluko omkhulu kakhulu.
I-cold-formed metal-walled cross cross section kwi-residual stress distribution is curved, kunye nentsimbi eshushu egobileyo okanye intsimbi edibeneyo yokusabalalisa uxinzelelo olushiyekileyo kwi-cross section yifilimu encinci.
I-3, intsimbi eshushu eqengqelekayo yasimahla iphezulu kunentsimbi eqengqelekayo, ngoko ke iipropathi zentsimbi eziqengqelekayo zingcono kunentsimbi eqengqelekayo.
