Magiredi a Chitsulo Chotentha Chozungulira

Chitsulo chotenthetsera ndi chimodzi mwa zipangizo zomwe zimagwiritsidwa ntchito kwambiri popanga, kumanga, magalimoto, ndi makina olemera. Chodziwika chifukwa cha kusinthasintha kwake, kugwiritsa ntchito bwino ndalama, komanso mosavuta kupanga, chitsulo chotenthetsera chimabwera m'magulu osiyanasiyana, chilichonse chopangidwira makhalidwe enieni a makina ndi zofunikira pakugwira ntchito.

Kumvetsetsamagulu a chitsulo chokulungidwa chotenthazimathandiza mainjiniya, opanga zinthu, ndi akatswiri ogula zinthu kusankha zipangizo zoyenera mapulojekiti awo. Magiredi osiyanasiyana amasiyana mu mphamvu, kusinthasintha, kulimba, kusinthasintha, komanso kukana dzimbiri. M'nkhaniyi, tifufuza magulu akuluakulu ndi magiredi a chitsulo chotenthedwa, makhalidwe ake, ndi ntchito zomwe zimagwiritsidwa ntchito nthawi zambiri.

Kodi Chitsulo Chotentha Chokulungidwa N'chiyani?

Chitsulo chotenthedwa chimapangidwa ndi kutentha kwa slabs zachitsulo pamwamba pa kutentha kwawo kobwezeretsanso, nthawi zambiri pafupifupi 900°C mpaka 1100°C, kenako nkuzipinda m'mawonekedwe omwe mukufuna. Chifukwa chitsulocho chimapindidwa kutentha kwambiri, chimakhala chosavuta kuchipanga, zomwe zimapangitsa kuti chikhale choyenera kugwiritsidwa ntchito pazinthu zazikulu komanso momwe zimagwiritsidwira ntchito komwe kulekerera koyenera sikofunikira.

Chitsulocho chikagubuduzika, chimaziziritsidwa mumlengalenga, zomwe zingayambitse kusintha pang'ono kwa kukula kwake koma zimapangitsa kuti chivundikirocho chikhale cholimba kwambiri.

Zinthu Zofunika Kwambiri za Chitsulo Chotentha Chokulungidwa

  1. Kupangika Kwabwino- Zosavuta kupanga ndi kupindika popanga.

  2. Kulimba Kwambiri- Imatha kupirira katundu wolemera komanso kugundana.

  3. Kupanga Kotsika Mtengo- Kukonza kochepa poyerekeza ndi chitsulo chozizira chokulungidwa.

  4. Kusinthasintha- Yoyenera mafakitale osiyanasiyana.

  5. Kusiyanasiyana kwa Miyeso- Kulekerera sikolimba ngati chitsulo chozizira chokulungidwa, koma n'kovomerezeka pa ntchito zambiri.

Magulu Aakulu a Magiredi a Zitsulo Zotentha

Magulu achitsulo chotenthedwa nthawi zambiri amatha kugawidwa m'magulu anayi akuluakulu:

  1. Magiredi a Chitsulo cha Carbon

  2. Magiredi a Aloyi a Zitsulo

  3. Magiredi a Chitsulo cha High-Strength Low-Alloy (HSLA)

  4. Magiredi Apadera a Ntchito Zinazake

1. Magiredi a Chitsulo cha Kaboni

Zitsulo za kaboni ndi zitsulo zotentha kwambiri zomwe zimagubuduzidwa, zomwe zimafotokozedwa ndi kuchuluka kwa kaboni komwe zili nako.

  • Mapulogalamu– Masiponji, zida zodulira, mawaya amphamvu kwambiri.

2. Magiredi a Aloyi a Chitsulo

Zitsulo za alloy zili ndi zinthu zina monga chromium, molybdenum, nickel, kapena vanadium kuti ziwonjezere mphamvu.

  • 4140 Chitsulo– Chitsulo cha Chromium-molybdenum chokhala ndi mphamvu zambiri, kulimba, komanso kukana kuwonongeka. Chofala kwambiri m'mafakitale a magalimoto, mafuta, ndi gasi.

  • 4340 Chitsulo– Chitsulo cha alloy cha nickel-chromium-molybdenum chodziwika bwino chifukwa cha mphamvu zake zambiri komanso kukana kutopa.

  • 8620 Chitsulo– Aloyi ya nickel-chromium-molybdenum yomwe imagwiritsidwa ntchito pazinthu zopangidwa ndi carburizing zomwe zimafuna pakati pa chinthu cholimba komanso pamwamba pake.

3. Magiredi a Chitsulo cha High-Strength Low-Alloy (HSLA)

Zitsulo za HSLA zimapangidwa kuti zipereke mphamvu zabwino zamakina komanso kukana dzimbiri kuposa chitsulo cha kaboni, popanda kuwonjezera kulemera kwake.

  • Chitsulo cha A572- Chitsulo champhamvu kwambiri chomwe chimagwiritsidwa ntchito pa milatho, nyumba, ndi zida zomangira.

  • Chitsulo cha A588 (Chitsulo Chowongolera Nyengo)- Muli mkuwa ndi zinthu zina zosakaniza kuti zithandizire kukana dzimbiri; zimagwiritsidwa ntchito m'nyumba zakunja popanda kupenta.

  • S355MC- Chitsulo champhamvu kwambiri chomwe chimagwiritsidwa ntchito mu mafelemu a magalimoto ndi chassis.

4. Magiredi Apadera a Ntchito Zinazake

Magiredi ena achitsulo chotenthedwa chopangidwa ndi kutentha amapangidwa kuti agwirizane ndi zofunikira zina:

  • AR400 / AR500- Chitsulo chosagwira ntchito yowononga chomwe chimagwiritsidwa ntchito popanga zida zamigodi ndi makina olemera.

  • Zitsulo Zomanga Zombo (AH36, DH36)- Zitsulo zolimba kwambiri zogwiritsidwa ntchito m'madzi ndi m'mphepete mwa nyanja.

  • Zitsulo Zopondereza (A516 Giredi 70)- Yopangidwira ma boiler ndi zotengera zopanikizika.

  • Zitsulo za Sitima- Magiredi apadera a kukana kuwonongeka kwambiri komanso kulimba kwa njanji.

Miyezo Yapadziko Lonse ya Chitsulo Chotentha Chokulungidwa

Mayiko osiyanasiyana amagwiritsa ntchito njira zawozawo zogawa ndi miyezo ya chitsulo chotenthedwa:

  • ASTM (American Society for Testing and Materials) (Bungwe la Kuyesa ndi Zipangizo la ku America)- Yofala ku United States, mwachitsanzo, ASTM A36, ASTM A572.

  • EN (European Norm)- Miyezo ya ku Europe monga EN 10025-2 (S235, S355).

  • JIS (Miyezo Yamakampani Yaku Japan)- Zitsanzo zikuphatikizapo SS400 ndi SM490.

  • GB (Miyezo Yadziko Lonse Yachi China)– Q235, Q345.

  • Miyezo ya ISO- Malangizo ogwirizana padziko lonse lapansi.

Kusankha Chitsulo Chotentha Choyenera

Posankha mtundu wa chitsulo chotenthedwa, ganizirani izi:

  1. Zofunikira pa Mphamvu ya Makina- Sankhani giredi yokhala ndi mphamvu yoyenera yokoka komanso yotulutsa mphamvu.

  2. Kutha kupotoka– Ma carbon ochepa amapereka kuthekera kowongoleredwa bwino.

  3. Kukana Kudzikundikira- Zitsulo zozungulira kapena zitsulo zosakanikirana ndi aloyi kuti zikhale zovuta.

  4. Kukhazikika- Zitsulo zofewa zimakhala zosavuta kupindika ndi kupanga mawonekedwe.

  5. Mtengo ndi Kupezeka Kwake- Magiredi ena amapezeka mosavuta m'misika ina.

Chitsulo Chokulungidwa ndi Moto Chozungulira vs. Chitsulo Chokulungidwa ndi Cold

Mbali Chitsulo Chotentha Chokulungidwa Chitsulo Chozizira Chozungulira
Kutentha Kwambiri Kutentha kopitilira muyeso wa recrystallization Kutentha kocheperako kwa recrystallization
Kumaliza Pamwamba Yolimba yokhala ndi sikelo Yosalala komanso yopukutidwa
Kulekerera Zosalondola kwenikweni Zolondola kwambiri
Mtengo Pansi Zapamwamba
Mphamvu Kawirikawiri otsika Kuchuluka kwa ntchito pambuyo pa kuuma

Chitsulo chokulungidwa ndi chotentha ndicho chisankho chomwe chimakonda kugwiritsidwa ntchito pomwe mtengo ndi kuphweka kwa kupanga ndizofunikira kwambiri kuposa kumalizidwa bwino kwa pamwamba.

Mapulogalamu Ofala Poyerekeza ndi Gulu

  • ASTM A36- Mizati ya kapangidwe ka nyumba, njira, mbale.

  • Chitsulo cha Aloyi cha 4140- Ma shaft, mabolt, magiya.

  • Chitsulo Chozungulira cha A588- Milatho, ziboliboli zakunja, makoma a nyumba.

  • AR400- Zipangizo za migodi ndi zomangamanga.

  • S355MC- Chassis yamagalimoto, mafelemu olemera.

Kusunga Ubwino mu Chitsulo Chotentha Chokulungidwa

Pofuna kuonetsetsa kuti ntchito ikuyenda bwino, ogulitsa odalirika mongasakysteelperekani chitsulo chokulungidwa ndi moto chokhala ndi mawonekedwe otsimikizika a makina, kulondola kwa miyeso, ndi malipoti oyesa ovomerezeka. Izi zimathandiza mafakitale kupewa kukonzanso kokwera mtengo ndikuwonetsetsa kuti akutsatira miyezo ya uinjiniya.

Zochitika Zamtsogolo mu Magiredi a Zitsulo Zotentha Zozungulira

Makampani opanga zitsulo akusintha kuti apange zinthu zokhazikika, kupanga zinthu zopangidwa ndi alloy bwino, komanso njira zotetezera pamwamba.

  • Zida Zapamwamba za HSLA- Kupereka chiŵerengero chapamwamba cha mphamvu ndi kulemera.

  • Zitsulo za Aloyi Zosagonjetsedwa ndi Dzimbiri- Kuchepetsa kufunika kwa zophimba.

  • Kupanga Kopanda Chilengedwe- Kuchepetsa mpweya woipa wa carbon m'mafakitale.

Kupita patsogolo kumeneku kudzapatsa mainjiniya zosankha zambiri komanso magwiridwe antchito abwino pa ntchito zinazake.

Mapeto

Chitsulo chotenthedwa ndi chinthu chofunikira kwambiri m'mafakitale ambiri, chomwe chili ndi mitundu yosiyanasiyana kuyambira chitsulo chofatsa cha kaboni wochepa mpaka zitsulo zolimba kwambiri komanso zotentha. Mtundu uliwonse umapereka mawonekedwe apadera a makina ndi mankhwala oyenera kugwiritsidwa ntchito mwanjira inayake.

Kumvetsetsa mitundu yosiyanasiyana ya chitsulo chotenthedwa, makhalidwe ake, ndi miyezo yake kumatsimikizira kuti mutha kusankha zinthu zoyenera pa ntchito yanu, kaya ndi za matabwa omangira nyumba, zida zamagalimoto, zotengera zopanikizika, kapena zida zosagwirizana ndi kusweka. Kugwira ntchito ndi ogulitsa odalirika mongasakysteelZimatsimikizira kuti mumalandira zipangizo zapamwamba komanso zovomerezeka zomwe zikugwirizana ndi zosowa zanu, kuonetsetsa kuti chitetezo, magwiridwe antchito, komanso kulimba kwa nthawi yayitali.
