Mipope yachitsulo yokhala ndi m'mimba mwake imatchedwanso mipope yachitsulo yokhala ndi m'mimba mwake, yomwe imatanthawuza mapaipi achitsulo opangidwa ndi zitsulo zotentha kapena zigawo za electro-galvanized pamwamba pa mipope yachitsulo yozungulira. Galvanizing kuonjezera dzimbiri kukana mipope zitsulo ndi kuwonjezera moyo wawo utumiki. Mipope ya malata imagwiritsidwa ntchito kwambiri. Kuphatikiza pa kugwiritsidwa ntchito ngati mapaipi amadzimadzi otsika kwambiri monga madzi, gasi, ndi mafuta, amagwiritsidwanso ntchito ngati mapaipi amafuta ndi mapaipi amafuta pamafakitale amafuta, makamaka minda yamafuta akunyanja, komanso ngati zotenthetsera mafuta ndi ma condensation. mu zipangizo zophikira mankhwala. Mapaipi a zoziziritsa kukhosi, osinthanitsa mafuta a malasha, mapaipi a milu ya mipope ya trestle, mafelemu othandizira ma ngalande amigodi, ndi zina zambiri.

Njira yayikulu yopangira chitoliro chachitsulo:

1. Hot kukankha m'mimba mwake njira yowonjezera

Zida zokulira m'mimba mwake ndizosavuta, zotsika mtengo, zosavuta kuzisamalira, zandalama, komanso zolimba, ndipo mawonekedwe azinthu amatha kusinthidwa mosavuta. Ngati mukufuna kukonza mapaipi azitsulo amitundu yayikulu ndi zinthu zina zofananira, muyenera kuwonjezera zina. Ndi oyenera kupanga sing'anga ndi woonda-mipanda zitsulo mipope lalikulu m'mimba mwake, komanso kutulutsa mipope wandiweyani-mipanda amene saposa mphamvu zida.

2. Hot extrusion njira

Chosowekacho chiyenera kukonzedwa kale ndi makina asanayambe extrusion. Pamene extruding zovekera chitoliro ndi awiri a zosakwana 100mm, ndalama zida ndi yaing'ono, zinthu zinyalala zochepa, ndi luso ndi okhwima. Komabe, pamene kukula kwa chitoliro kumawonjezeka, njira yotentha yotulutsa mpweya imafuna zida zazikulu za tonnage ndi zida zamphamvu, ndipo dongosolo loyenera lolamulira liyeneranso kukwezedwa.

3. Kuboola ndi kugudubuza kotentha

Kuboola kotentha kumatengera kufalikira kwa nthawi yayitali komanso kupitilira-kugudubuza. Kugudubuza kwautali ndi kutambasula makamaka kumaphatikizapo kugudubuza kwa chubu ndi mandrel ochepa osuntha, machubu opitirira ndi mandrel oima pang'ono, machubu atatu opitirira ndi mandrel ochepa, ndi machubu opitirira ndi mandrel oyandama. Njirazi zimakhala ndi zopanga zambiri, kugwiritsa ntchito zitsulo zochepa, zinthu zabwino, ndi machitidwe owongolera, ndipo zimagwiritsidwa ntchito kwambiri.

Pakali pano, waukulu njira kupanga lalikulu m'mimba mwake zitsulo mipope m'dziko langa ndi otentha adagulung'undisa lalikulu-m'mimba mwake zitsulo mapaipi ndi kutentha anawonjezera awiri zitsulo mipope. Kufotokozera kwakukulu kwa mapaipi achitsulo osakanizidwa ndi kutentha ndi 325 mm-1220 mm ndipo makulidwe ake ndi 120mm. Mapaipi achitsulo osakanizika otenthedwa ndi kutentha amatha kutulutsa miyeso yomwe si yadziko lonse. Chitoliro chopanda msoko ndi chomwe timachitcha nthawi zambiri kukulitsa kutentha. Ndi njira yomaliza ya chitoliro momwe mapaipi achitsulo okhala ndi kachulukidwe kakang'ono koma kuchepera kolimba kumakulitsidwa ndi njira zodutsa kapena zojambula. Makulidwe zitsulo mipope mu nthawi yochepa akhoza kupanga sanali muyezo ndi wapadera mitundu ya mapaipi opanda msokonezo ndi otsika mtengo ndi mkulu kupanga dzuwa. Izi ndizomwe zikuchitika pakukula kwa chitoliro.

Mipope yachitsulo ikuluikulu ikuluikulu imatsekeredwa ndikutenthedwa musanachoke kufakitale. Izi zimatchedwa annealed state. Cholinga cha annealing makamaka ndi kuthetsa zilema structural ndi kupsyinjika kwamkati zomwe zatsalira kuchokera ku ndondomeko yapitayi ndikukonzekera dongosolo ndi ntchito zomwe zidzachitike pambuyo pake, monga chitsulo chopangidwa ndi alloy structural steel, structural chitsulo chokhala ndi kulimba kotsimikizika, chitsulo chozizira, ndi kunyamula. zitsulo. Zitsulo monga chitsulo chachitsulo, chitsulo cha turbine blade chitsulo, ndi chitsulo chosapanga dzimbiri chosatentha chamtundu wa chingwe nthawi zambiri zimaperekedwa m'malo otsekedwa.

Large m'mimba mwake zitsulo processing njira:

1. Kugudubuza; njira yopangira mphamvu yomwe zitsulo zazitsulo zokhala ndi m'mimba mwake zazikulu zimadutsa pakati pa zodzigudubuza zozungulira (zosiyanasiyana). Chifukwa cha kuponderezedwa kwa odzigudubuza, gawo la mtanda limachepetsedwa ndipo kutalika kumawonjezeka. Iyi ndi njira yomwe imagwiritsidwa ntchito popanga mapaipi achitsulo okhala ndi mainchesi akulu. Njira yopangirayi imagwiritsidwa ntchito makamaka popanga mbiri yamapaipi azitsulo, mbale, ndi mapaipi. Agawanika ozizira kugudubuza ndi otentha anagubuduza.

2. Kupeka; njira yopangira mphamvu yomwe imagwiritsa ntchito mphamvu yobwerezabwereza ya nyundo yopukutira kapena kukakamiza kwa makina osindikizira kuti asinthe chosowacho kukhala mawonekedwe ndi kukula komwe tikufuna. Nthawi zambiri amagawidwa m'mafakitale aulere ndi kufa, nthawi zambiri amagwiritsidwa ntchito kupanga zida zokhala ndi magawo akulu akulu, mipope yachitsulo yamitundu yayikulu, etc.

3. Kujambula: Ndi njira yopangira yomwe imakoka chitsulo chopanda kanthu (chopangidwa, chubu, mankhwala, ndi zina zotero) kupyolera mu dzenje lakufa kuti likhale gawo lochepetseka komanso kutalika kwake. Ambiri aiwo amagwiritsidwa ntchito pozizira.

4. Extrusion; ndi njira yopangira momwe mapaipi achitsulo ozungulira m'mimba mwake amayika zitsulo mu silinda yotsekedwa yotsekedwa ndikugwiritsa ntchito kukakamiza kumbali imodzi kuti atulutse zitsulo kuchokera ku dzenje lodziwika kuti apeze zinthu zomalizidwa zofanana ndi kukula kwake. Amagwiritsidwa ntchito kwambiri popanga. Non-ferrous zitsulo lalikulu m'mimba mwake zitsulo chitoliro.
