Kugudubuza kotentha ndi kuzizira kozizira ndi mbale zachitsulo kapena njira zopangira mbiri, zimakhudza kwambiri kapangidwe kake ndi katundu wachitsulo.

Kugudubuza kwachitsulo kumakhala kotentha kwambiri, kugudubuza kozizira kumangogwiritsidwa ntchito popanga chitsulo chaching'ono ndi chitsulo cha pepala ndi zitsulo zina zolondola.

Chitsulo chozizira komanso chotentha:

Waya: 5.5-40 mm m'mimba mwake, ma coils, onse otentha adakulungidwa.Pambuyo pa kujambula kozizira, zimakhala za zojambula zozizira.

Chitsulo chozungulira: Kuphatikiza pa kulondola kwa kukula kwa zinthu zowala nthawi zambiri zimakhala zotentha, komanso zopukutira (zojambula zapamtunda).

Mvula zitsulo: otentha adagulung'undisa ozizira adagulung'undisa, ozizira adagulung'undisa zambiri woonda.

Chitsulo mbale: ozizira adagulung'undisa mbale zambiri woonda, monga mbale galimoto;Hot anagubuduza sing'anga wandiweyani mbale kwambiri, ndi ozizira anagubuduza makulidwe ofanana, maonekedwe n'zoonekeratu zosiyana.

Ngongole chitsulo: zonse otentha adagulung'undisa.

Chitsulo chubu: welded otentha adagulung'undisa ndi ozizira kukokedwa.

Channel ndi H mtengo: otentha adagulung'undisa.

Chitsulo chachitsulo: zinthu zoyaka zotentha.

Hot adagulung'undisa

Mwa tanthawuzo, ingot yachitsulo kapena billet ndizovuta kusokoneza ndi kukonza kutentha kwa firiji.Nthawi zambiri imatenthedwa mpaka 1100 ~ 1250 ℃ pakugudubuza.Kugudubuzika kumeneku kumatchedwa hot rolling.

Kutentha komaliza kwa kugudubuza kotentha nthawi zambiri kumakhala 800 ~ 900 ℃, ndiyeno nthawi zambiri kumakhala utakhazikika mumlengalenga, chifukwa chake kutentha kumakhala kofanana ndi chithandizo chamankhwala.

Zitsulo zambiri zimakulungidwa ndi kugudubuza kotentha.Chitsulo chotentha chotentha, chifukwa cha kutentha kwakukulu, pamwamba pa mapangidwe a pepala la oxide, motero amakhala ndi kukana kwa dzimbiri, akhoza kusungidwa panja.

Komabe, wosanjikiza chitsulo okusayidi ichi kumapangitsanso pamwamba pa otentha adagulung'undisa zitsulo akhakula ndi kukula zimasinthasintha kwambiri, kotero zitsulo ndi yosalala pamwamba, kukula zolondola ndi katundu makina abwino ayenera kugwiritsidwa ntchito ngati zopangira ndiyeno ozizira adagulung'undisa.

Ubwino:

Kupanga liwiro, zokolola zambiri, ndipo musawononge zokutira, zitha kupangidwa kukhala mawonekedwe amitundu yosiyanasiyana, kuti mukwaniritse zofunikira zomwe zimagwiritsidwa ntchito;Cold anagubuduza akhoza kutulutsa lalikulu pulasitiki mapindikidwe zitsulo, motero kukweza zokolola mfundo ya zitsulo.

Zoyipa:

1. Ngakhale kuti palibe kuponderezedwa kwa pulasitiki yotentha popanga ndondomekoyi, palinso kupanikizika kotsalira m'gawoli, zomwe zidzakhudza zitsulo zonse ndi zam'deralo;

2. Chigawo chozizira chozizira nthawi zambiri chimakhala chotseguka, chomwe chimapangitsa kuti kuuma kwaufulu kwa gawolo kukhale kochepa.N'zosavuta kupindika pamene yapindika, ndipo njosavuta kupindika ndi kupindika ikaipanikiza, ndipo mphamvu ya torsion imachepa.

3. Makulidwe a khoma lachitsulo chozungulira chozizira ndi chaching'ono, ndipo palibe makulidwe pakona pamene mbale imagwirizanitsa, kotero imakhala ndi mphamvu yofooka yonyamula katundu wokhazikika.

Kuzizira adagulung'undisa

Kuzizira kozizira kumatanthawuza njira yogubuduza yosinthira mawonekedwe a chitsulo mwa kufinya chitsulo pansi pa kupanikizika kwa wodzigudubuza pa kutentha.Kumatchedwa kuzizira kozizira, ngakhale kuti ndondomekoyi imatenthetsanso zitsulo.Kunena zachindunji, kugudubuzika kozizira kumagwiritsa ntchito zitsulo zotentha zopindika ngati zida zopangira, zomwe zimakonzedwa mokakamizidwa pambuyo pa pickling ya asidi kuti achotse sikelo ya oxide, ndipo zomalizidwazo zimakulungidwa zolimba zolimba.

Nthawi zambiri ozizira adagulung'undisa zitsulo monga kanasonkhezereka, mtundu zitsulo mbale ayenera annealed, kotero plasticity ndi elongation ndi zabwino, chimagwiritsidwa ntchito galimoto, zipangizo kunyumba, hardware ndi mafakitale ena.Pamwamba pa mbale yozizira imakhala yosalala, ndipo dzanja limakhala losalala, makamaka chifukwa cha pickling.Kumapeto kwa mbale yowotchayo sikungakwaniritse zofunikira, kotero kuti chingwe chachitsulo chotenthetsera chiyenera kukhala chozizira, ndipo makulidwe a zitsulo zotentha ndi 1.0mm, ndipo mzere wachitsulo wozizira umatha kufika 0.1mm. .Kugudubuza kotentha kumadutsa pamwamba pa crystallization kutentha, kuzizira kozizira kumadutsa pansi pa kutentha kwa crystallization.

Kusintha kwa mawonekedwe achitsulo chifukwa cha kuzizira kozizira kumakhala kopitilira kuzizira.Kuzizira kozizira komwe kumachitika chifukwa cha njirayi kumawonjezera mphamvu ndi kuuma kwa koyilo yolimba ndikuchepetsa kulimba ndi index ya pulasitiki.

Kuti mugwiritse ntchito momaliza, kugudubuza kozizira kumasokoneza magwiridwe antchito ndipo chinthucho ndi choyenera pazigawo zomwe zangopunduka.

Ubwino:

Itha kuwononga kapangidwe kachitsulo kachitsulo, kuyeretsa kukula kwa chitsulo, ndikuchotsa zolakwika za microstructure, kuti chitsulocho chikhale chophatikizika ndipo makina amawongoleredwa bwino.Kuwongolera uku kumawonekera makamaka pakugudubuza, kotero kuti chitsulo sichikhalanso isotropic pamlingo wina.Mavuvu, ming'alu ndi kumasuka komwe kumapangidwa panthawi yoponyera kumatha kuwotcherera pansi pa kutentha kwambiri komanso kupanikizika.

Zoyipa:

1. Pambuyo pakuwotcha kotentha, zitsulo zopanda zitsulo (makamaka sulfides ndi oxides, komanso silicates) muzitsulo zimakhala laminated ndi layered.Delamination imawononga kwambiri mphamvu yachitsulo motsatira makulidwe ake ndipo imatha kung'ambika mkati mwa weld shrinkage.Kupsyinjika kwanuko komwe kumabwera chifukwa cha weld shrinkage nthawi zambiri kumakhala kovutirapo kangapo, komwe kumakhala kokulirapo kuposa komwe kumachitika chifukwa cha katundu.

2. Kupanikizika kotsalira komwe kumachitika chifukwa cha kuzizira kosiyana.Kupsyinjika kotsalira ndi kupanikizika kwapakati pa gawo lokhazikika popanda mphamvu yakunja.Mitundu yonse yazitsulo zopindika zotentha zimakhala ndi zotsalira zamtunduwu.Kukula kwa gawo lalikulu la zitsulo zamagulu ambiri, kupanikizika kotsalira kumakhala kwakukulu.Ngakhale kupsinjika kotsalira ndikudziyimira pawokha, kumakhala ndi zotsatira zina pakuchita kwa membala wachitsulo pansi pa mphamvu yakunja.Monga deformation, kukhazikika, kukana kutopa ndi zina zingakhale ndi zotsatira zoipa.

Pomaliza:

Kusiyana pakati pa kuzizira kozizira ndi kugudubuza kotentha ndiko makamaka kutentha kwa ndondomeko yogudubuza."Kuzizira" kumasonyeza kutentha kwabwino, ndipo "kutentha" kumasonyeza kutentha kwakukulu.

Kuchokera pamalingaliro azitsulo, malire pakati pa kuzizira kozizira ndi kugudubuza kotentha ayenera kusiyanitsidwa ndi kutentha kwa recrystallization.Ndiko kuti, kugubuduza m'munsimu kutentha recrystallization ozizira anagubuduza, ndi anagubuduza pamwamba pa recrystallization kutentha ndi otentha anagubuduza.The recrystallization kutentha zitsulo ndi 450 ~ 600 ℃.
