1. Gulu la mbale zachitsulo (kuphatikiza chitsulo chamizere):

1. Gulu mwa makulidwe: (1) Mbale yopyapyala (2) Mbale yapakatikati (3) Mbale yokhuthala (4) Mbale yokhuthala kwambiri

2. Zodziwika ndi njira yopangira: (1) Mbale yachitsulo yotentha (2) Yozizira yozungulira zitsulo

3. Gulu ndi mawonekedwe a pamwamba: (1) Chipepala cha galvanized (chipepala chotentha choviika ngati malata, pepala lopangidwa ndi electro-galvanized) (2) Pepala lokutidwa ndi malata (3) Chitsulo chophatikizika (4) Pepala lopaka utoto

4. Gulu ndi ntchito: (1) Mlatho zitsulo mbale (2) Boiler zitsulo mbale (3) Shipbuilding zitsulo mbale (4) Zida zitsulo mbale (5) Galimoto zitsulo mbale (6) Padenga zitsulo mbale (7) Structural zitsulo mbale (8) ) Mbale yachitsulo yamagetsi (pepala lachitsulo la silicon) (9) mbale yachitsulo ya Spring (10) Zina

2. Kugudubuzika kotentha:

Makolo opukutira otentha Mbale zachitsulo zomanga Mambale a zitsulo zamagalimoto Zomangira zitsulo Zomangira zitsulo Mlatho mbale zitsulo Boiler zitsulo Chidebe chachitsulo mbale zitsulo Zosagwira ndi dzimbiri M'malo mwa kuzizira ndi kutentha Chitsulo cha Baosteel chachikulu ndi cholemera Chitsulo chosayaka ndi kuzizira

3. Kuzizira kozizira:

Ma coils okulungidwa olimbaMapepala opiringizidwa ndi magetsi GB a malata opukutidwa ndi WISCO silicon chitsulo kugwiritsa ntchito

4. Chitsulo chowiritsa ndi mbale yachitsulo yopha:

1. Chitsulo chowiritsa mbale ndi mbale yachitsulo yotentha-yokulungidwa kuchokera ku chitsulo wamba cha carbon structural chitsulo chowira.Chitsulo chowiritsa ndi mtundu wachitsulo wokhala ndi deoxidation yosakwanira.Kuchepa kochepa chabe kwa deoxidizer kofooka kumagwiritsidwa ntchito pochotsa chitsulo chosungunuka.Mpweya wa okosijeni wachitsulo chosungunuka ndi wochuluka kwambiri.Chitsulo chosungunuka chikabayidwa mu nkhungu ya ingot, mpweya ndi mpweya wa carbon zimagwira ntchito kuti zipange mpweya wochuluka, zomwe zimapangitsa kuti zitsulo zosungunukazo ziwira., Chitsulo chowiracho chinatenga dzina lake kuchokera apa.Chitsulo chachitsulo chimakhala ndi mpweya wochepa, ndipo chifukwa sichigwiritsa ntchito ferrosilicon kuti chiwonongeko, zomwe zili muzitsulo za silicon ndizochepa (Si <0.07%).Wosanjikiza akunja zitsulo otentha ndi crystallized pansi pa zikhalidwe za chiwawa mukubwadamuka wa chitsulo chosungunuka chifukwa cha kuwira, kotero wosanjikiza pamwamba ndi woyera ndi wandiweyani, ndi zabwino pamwamba khalidwe, plasticity wabwino ndi kupondaponda katundu, palibe lalikulu anaikira shrinkage mabowo, ndi kudula mutu. Mlingo wopangira zitsulo zokhala ndi zitsulo ndi zophweka, kugwiritsa ntchito ferroalloy ndi kochepa, ndipo mtengo wachitsulo ndi wotsika.Zitsulo zowiritsa zimagwiritsidwa ntchito kwambiri popanga magawo osiyanasiyana osindikizira, zomangamanga ndi zomangamanga komanso zida zina zosafunika kwenikweni zamakina.Komabe, pali zonyansa zambiri pakatikati pa chitsulo chowira, tsankho ndi lalikulu, kapangidwe kake sikokhuthala, ndipo mawonekedwe amakina ndi osagwirizana.Panthawi imodzimodziyo, chifukwa cha kuchuluka kwa gasi muzitsulo, kulimba kwake kumakhala kochepa, kuzizira kwa brittleness ndi kukalamba kumakhala kwakukulu, ndipo ntchito yowotcherera imakhala yosauka.Chifukwa chake, mbale zowiritsa zachitsulo sizoyenera kupanga zida zowotcherera ndi zida zina zofunika zomwe zimanyamula katundu ndikugwira ntchito pansi pa kutentha kochepa.

2. Anapha zitsulo mbale ndi mbale zitsulo zopangidwa wamba mpweya structural zitsulo kuphedwa zitsulo ndi otentha anagudubuza.Anaphedwa zitsulo kwathunthu deoxidized zitsulo.Chitsulo chosungunuka chimakhala ndi deoxidized ndi ferromanganese, ferrosilicon ndi aluminiyamu musanathire.Mpweya wa okosijeni wa chitsulo chosungunuka ndi chochepa (nthawi zambiri 0.002-0.003%), ndipo chitsulo chosungunuka chimakhala chodekha mu nkhungu ya ingot.Palibe chodabwitsa chowiritsa, chifukwa chake dzina lachitsulo chophedwa.Pazikhalidwe zogwirira ntchito, palibe thovu muzitsulo zophedwa, ndipo kapangidwe kake ndi kofanana komanso kophatikizana;chifukwa cha kuchepa kwa okosijeni, chitsulocho chimakhala ndi ma oxide ochepa, oyeretsedwa kwambiri, kuzizira kozizira komanso chizolowezi chokalamba;panthawi imodzimodziyo, kulekanitsa zitsulo zophedwa ndi zazing'ono, Zochitazo zimakhala zofanana komanso zimakhala zapamwamba.Kuipa kwa zitsulo zophedwa ndi shrinkage yokhazikika, zokolola zochepa komanso mtengo wapamwamba.Chifukwa chake, chitsulo chophedwa chimagwiritsidwa ntchito makamaka pazinthu zomwe zimalimbana ndi kutentha pang'ono, zida zowotcherera, ndi zida zina zomwe zimafunikira mphamvu yayikulu.

Zitsulo zazitsulo zotsika zimaphedwa komanso mbale zachitsulo zophedwa.Chifukwa cha mphamvu zake zapamwamba komanso ntchito zapamwamba, zimatha kusunga zitsulo zambiri ndikuchepetsa kulemera kwa kapangidwe kake, ntchito yake yakhala yowonjezereka.

5. Mpweya wapamwamba kwambiri wa carbon structural steel plate:

Chitsulo chapamwamba cha carbon structural ndi chitsulo cha carbon chomwe chili ndi mpweya wosakwana 0.8%.Chitsulochi chimakhala ndi sulfure yochepa, phosphorous ndi inclusions zopanda zitsulo kuposa carbon structural steel, ndipo zimakhala ndi makina abwino kwambiri.

Zitsulo zapamwamba za carbon structural zitha kugawidwa m'magulu atatu molingana ndi zomwe zili ndi mpweya wosiyanasiyana: chitsulo chochepa cha carbon (C≤0.25%), zitsulo zapakati-mpweya (C ndi 0.25-0.6%) ndi zitsulo za carbon (C> 0.6) %).

Malinga ndi okhutira osiyanasiyana manganese, apamwamba mpweya structural zitsulo akhoza kugawidwa m'magulu awiri: yachibadwa manganese okhutira (manganese zili 0.25% -0.8%) ndi apamwamba manganese okhutira (manganese zili 0,70% -1.20%).Yotsirizirayi ili ndi makina abwinoko.Magwiridwe ndi processing ntchito.

1. Mpweya wapamwamba kwambiri wa carbon structural chitsulo chotenthetsera ndi chingwe chachitsulo Chitsulo chapamwamba cha carbon structural chitsulo chotentha-chopanda chitsulo chopyapyala ndi zitsulo zimagwiritsidwa ntchito pamagalimoto, makampani oyendetsa ndege ndi zina.zitsulo zake makaladi ndi rimmed zitsulo: 08F, 10F, 15F;kuphedwa zitsulo: 08, 08AL, 10, 15, 20, 25, 30, 35, 40, 45, 50. Low carbon zitsulo mbale pansi 25 ndi 25, 30 ndi Pamwamba 30 ndi sing'anga mpweya zitsulo mbale.

2. Mpweya wapamwamba kwambiri wa carbon structural chitsulo chowotcha-wokulungidwa ndi zitsulo zokhuthala ndi zitsulo zazikuluzikulu zazitsulo zapamwamba za carbon structural zitsulo zopyapyala ndi zitsulo zazikulu zimagwiritsidwa ntchito pamakina osiyanasiyana.Makalasi ake zitsulo ndi otsika carbon zitsulo kuphatikizapo: 05F, 08F, 08, 10F, 10, 15F, 15, 20F, 20, 25, 20Mn, 25Mn, etc.;zitsulo zapakati za carbon zikuphatikizapo: 30, 35, 40, 45, 50, 55, 60, 30Mn, 40Mn, 50Mn, 60Mn, etc.;zitsulo zapamwamba za carbon zikuphatikizapo: 65, 70, 65Mn, etc.

6. Mbale yapadera yachitsulo:

1. Chitsulo chotengera chotengera chokakamiza: Gwiritsani ntchito capital R kuwonetsa kumapeto kwa giredi.Gawoli likhoza kuwonetsedwa ndi zokolola kapena kaboni kapena ma alloying element.Monga: Q345R, Q345 ndiye zokolola.Chitsanzo china: 20R, 16MnR, 15MnVR, 15MnVNR, 8MnMoNbR, MnNiMoNbR, 15CrMoR, ndi zina zotero zonse zimayimiridwa ndi carbon content kapena alloying elements.
