Kodi chitsulo ndi chiyani ndipo chimapangidwa bwanji?
Chitsulo chikaphatikizidwa ndi carbon ndi zinthu zina chimatchedwa chitsulo. Chotsatiracho chimakhala ndi ntchito monga gawo lalikulu la nyumba, zomangamanga, zida, zombo, magalimoto, makina, zida zosiyanasiyana, ndi zida. Zogwiritsidwa ntchito ndizochulukira chifukwa cha zitsulo zolimba kwambiri komanso zotsika mtengo.
Ndani anapeza izo?
Zitsanzo zakale kwambiri zachitsulo zapezeka ku Turkey ndipo zidayamba mu 1800BC. Kupanga zitsulo zamakono kunayambira ku Sir Henry Bessemerof England yemwe adapeza njira yopangira ife voliyumu yapamwamba komanso yotsika mtengo.
Gulu la Jindalai Steel Group ndi Wopanga & Wotumiza kunja wachitsulo chosapanga dzimbiri coil/sheet/plate/strip/pipe.
Kodi pali kusiyana kotani pakati pa Iron ndi Steel?
Chitsulo ndi chinthu chochitika mwachilengedwe chomwe chimapezeka m'chilengedwe mkati mwa Iron Ore. Chitsulo ndiye gawo lalikulu la Chitsulo, chomwe ndi alloy ya Iron ndi kuwonjezera kwakukulu kwa Chitsulo. Chitsulo ndi champhamvu kuposa Chitsulo, chokhala ndi mphamvu zolimba komanso zopondereza.
Kodi chitsulo ndi chiyani?
● Chitsulo chimakhala ndi Mphamvu Zolimba Kwambiri
● Ndilosavuta kuumba - kulola kuti lipangidwe mosavuta
● Kukhalitsa - kulola chitsulo kupirira mphamvu zakunja.
● Conductivity - ndi yabwino pa kutentha ndi magetsi, zothandiza pophika ndi waya.
● Luster - chitsulo chimakhala ndi maonekedwe okongola, asiliva.
● Kukaniza dzimbiri - kuonjezera zinthu zosiyanasiyana m'maperesenti osiyanasiyana kungapangitse chitsulo kukhala chitsulo chosapanga dzimbiri kuti chikhale cholimba kwambiri.
Champhamvu ndi chiani, Chitsulo kapena Titaniyamu?
Akasakaniza ndi zitsulo zina monga aluminium kapena vanadium, titaniyamu alloy ndi yamphamvu kuposa mitundu yambiri yazitsulo. Pankhani yamphamvu kwambiri, ma aloyi abwino kwambiri a titaniyamu amamenya zitsulo zosapanga dzimbiri zotsika mpaka zapakati. Komabe, chitsulo chosapanga dzimbiri chapamwamba kwambiri ndi champhamvu kuposa ma aloyi a titaniyamu.
Mitundu 4 yachitsulo ndi chiyani?
(1) Chitsulo cha Carbon
Zitsulo za kaboni zimakhala ndi Iron, Carbon, ndi zinthu zina zophatikizira monga Manganese, Silicon, ndi Copper.
(2) Chitsulo cha Aloyi
Zitsulo za alloy zimakhala ndi zitsulo zodziwika bwino mosiyanasiyana, zomwe zimapangitsa kuti chitsulo chamtunduwu chikhale choyenera kugwiritsidwa ntchito mwapadera.
(3) Chitsulo chosapanga dzimbiri
Ngakhale zitsulo zosapanga dzimbiri zimakhala ndi ma alloys angapo azitsulo, nthawi zambiri zimakhala ndi 10-20 peresenti ya chromium, zomwe zimapangitsa kuti ikhale chinthu choyambirira. Poyerekeza ndi mitundu ina yazitsulo, zitsulo zosapanga dzimbiri zimakhala zolimba kuwirikiza pafupifupi 200 ku dzimbiri, makamaka mitundu yomwe ili ndi 11 peresenti ya chromium.
(4) Chitsulo cha Chida
Chitsulo chamtunduwu chimapangidwa potentha kwambiri ndipo nthawi zambiri chimakhala ndi zitsulo zolimba monga tungsten, cobalt, molybdenum, ndi vanadium. Popeza sizimawotcha kutentha komanso zimakhala zolimba, zitsulo zamagetsi zimagwiritsidwa ntchito podula ndi kubowola.
Kodi kalasi yamphamvu kwambiri ndi iti?
SUS 440- yomwe ndi chitsulo chodula kwambiri chomwe chili ndi kuchuluka kwa kaboni, imakhala ndi malire abwinoko ikatenthedwa bwino. Itha kuumitsidwa mpaka kuuma kwa Rockwell 58, ndikupangitsa kukhala imodzi mwazitsulo zolimba kwambiri zosapanga dzimbiri.
Chifukwa chiyani chitsulo sichimatchedwa chitsulo?
Limodzi mwa mafunso omwe amafunsidwa kawirikawiri ponena za chitsulo ndi chifukwa chiyani chitsulo sichimatchulidwa ngati chitsulo? Chitsulo, pokhala aloyi ndipo kotero si chinthu choyera, sichiri chitsulo koma kusintha kwa chimodzi m'malo mwake. Zimapangidwa pang'ono ndi chitsulo, chitsulo, koma chifukwa zilinso ndi carbon yopanda zitsulo pamapangidwe ake, sizitsulo zoyera.
Ndi mtundu uti womwe umagwiritsidwa ntchito kwambiri?
304 Stainless Steel kapena SUS 304 kalasi yodziwika kwambiri; chitsulo chosapanga dzimbiri cha 18/8 (18% chromium, 8% nickel). Kunja kwa US, amadziwika kuti "A2 zitsulo zosapanga dzimbiri", malinga ndi ISO 3506 (osasokonezedwa ndi chitsulo cha A2)
Kodi chitsulo ndi chinthu chokhazikika?
Chitsulo ndi chinthu chokhazikika mwapadera chifukwa chikapangidwa chimatha kugwiritsidwa ntchito, ngati chitsulo, mpaka kalekale. Chitsulo chimagwiritsidwanso ntchito mopanda malire, kotero kuti ndalama zopangira zitsulo siziwonongeka ndipo zitha kuthandizidwa ndi mibadwo yamtsogolo.
Zosangalatsa zina zachitsulo
● Ngakhale kuti chitsulo chimakhala cholimba kwambiri pachokha, chitsulo chimatha kukhala champhamvu kuwirikiza ka 1000 kuposa chitsulo.
● Zitsulo zimachita dzimbiri pang'onopang'ono kapenanso kuzimiratu pamene mphamvu ya magetsi ikudutsa muzitsulo. Izi zimadziwika kuti Cathodic Protection ndipo zimagwiritsidwa ntchito popanga mapaipi, zombo, ndi zitsulo mu konkire.
● Zitsulo ndizomwe zimagwiritsidwanso ntchito kwambiri ku North America - pafupifupi 69% yazogwiritsidwanso ntchito chaka chilichonse, zomwe zimaposa pulasitiki, mapepala, aluminiyamu, ndi magalasi.
● Zitsulo zinayamba kugwiritsidwa ntchito pomanga nyumba zosanja kwambiri m’chaka cha 1883.
● Zimatengera matabwa oposa 40 kuti apange nyumba yamatabwa - nyumba yopangidwa ndi chitsulo imagwiritsa ntchito magalimoto 8 opangidwanso.
● Galimoto yoyamba yachitsulo inapangidwa m’chaka cha 1918
● Zitsulo 600 kapena zitini zimakonzedwanso sekondi iliyonse.
● Matani 83,000 azitsulo anagwiritsidwa ntchito popanga Bridge Gate Bridge.
● Kuchuluka kwa mphamvu zofunika kupanga tani yachitsulo yadulidwa pakati pazaka 30 zapitazi.
● Mu 2018, chuma cha padziko lonse chinapanga matani okwana 1,808.6 miliyoni. Izi zikufanana ndi kulemera kwa Eiffel Towers pafupifupi 180,249.
● N’kutheka kuti panopa mwazunguliridwa ndi zitsulo. Chida chodziwika bwino chapakhomo chimapangidwa ndi 65% yazinthu zachitsulo.
● Zitsulo zilinso mumagetsi anu! Pazinthu zonse zomwe zimapanga makompyuta ambiri, pafupifupi 25% yake ndi chitsulo.
Jindalai Steel Group- omwe amadziwika kuti amapanga zitsulo zaku China. Tili ndi zaka zopitilira 20 zachitukuko m'misika yapadziko lonse lapansi ndipo pano tili ndi mafakitale awiri omwe amapanga matani opitilira 400,000 pachaka. Ngati mukufuna kudziwa zambiri zazitsulo zazitsulo, talandirani kuti mutilankhule lero kapena funsani mtengo.
