1. Kodi Hot Rolled Steel Material Magiredi ndi Chiyani?
Chitsulo ndi aloyi yachitsulo yomwe imakhala ndi mpweya wochepa. Zinthu zopangidwa ndi zitsulo zimakhala ndi mitundu yosiyanasiyana kutengera kuchuluka kwa mpweya womwe uli nawo. Mitundu yosiyanasiyana ya zitsulo imagawidwa m'magulu malinga ndi kuchuluka kwa mpweya womwe uli nawo. Mitundu ya zitsulo zotentha imagawidwa m'magulu otsatirawa a kaboni:
Chitsulo chopanda mpweya wokwanira kapena chopepuka chili ndi kaboni wochepera 0.3%.
Chitsulo chapakati cha kaboni chili ndi 0.3% mpaka 0.6% ya kaboni.
Zitsulo zokhala ndi kaboni wambiri zimakhala ndi kaboni woposa 0.6%.
Zinthu zina zochepa zophatikizira monga chromium, manganese kapena tungsten zimawonjezedwanso kuti apange mitundu yambiri yachitsulo. Mitundu yosiyanasiyana yachitsulo imapereka zinthu zosiyanasiyana monga mphamvu yokoka, kusinthasintha, kusinthasintha, kulimba, komanso kutentha ndi magetsi.
2. Kusiyana pakati pa Chitsulo Chotentha Chozunguliridwa ndi Chitsulo Chozizira Chozunguliridwa
Zinthu zambiri zopangidwa ndi zitsulo zimapangidwa m'njira ziwiri zazikulu: kupondaponda kotentha kapena kupondaponda kozizira. Chitsulo chopondaponda chotentha ndi njira yopangira chitsulo chomwe chimapondaponda kutentha kwambiri. Nthawi zambiri, kutentha kwa chitsulo chopondaponda chotentha kumapitirira 1700°F. Chitsulo chopondaponda chozizira ndi njira yomwe chitsulo chimapondaponda kutentha kwa chipinda.
Ndikofunikira kudziwa kuti chitsulo chokulungidwa chotentha ndi chitsulo chokulungidwa chozizira sizitsulo zamtengo wapatali. Ndi njira zopangira zinthu zosiyanasiyana zachitsulo.
Njira Yopangira Zitsulo Zotentha
Chitsulo chotenthedwa chimaphatikizapo kupanga ndi kukulunga zitsulo kukhala mzere wautali pamene zikutenthedwa pamwamba pa kutentha kwake koyenera. Chitsulo chotenthedwa chofiira chimaperekedwa kudzera mu mipiringidzo yosiyanasiyana kuti chipangidwe ndikuchitambasula kukhala mzere woonda. Pambuyo popangidwa, mzere wachitsulo umaziziritsidwa ndi madzi ndikukulungidwa kukhala coil. Mitengo yosiyanasiyana yoziziritsira madzi imapanga zinthu zina zachitsulo mu chitsulocho.
Kubwezeretsa chitsulo chotenthedwa kutentha kwa chipinda kumathandiza kuti chikhale champhamvu komanso cholimba.
Chitsulo chokulungidwa chotentha nthawi zambiri chimagwiritsidwa ntchito pomanga, njanji za sitima, zitsulo za pepala, ndi zina zomwe sizifuna kumalizidwa kokongola kapena mawonekedwe ndi kulekerera kolondola.
Njira Yopangira Zitsulo Zozizira
Chitsulo chozungulira chozizira chimatenthedwa ndi kuzizira ngati chitsulo chozungulira chotentha koma kenako chimakonzedwanso pogwiritsa ntchito annealing kapena temper rolling kuti chikhale ndi mphamvu yolimba komanso mphamvu yotulutsa. Ntchito yowonjezera ndi nthawi yokonza zimawonjezera mtengo koma zimathandiza kuti zikhale zolekerera kwambiri ndipo zimapereka njira zosiyanasiyana zomaliza. Mtundu uwu wa chitsulo uli ndi mapeto osalala ndipo umagwiritsidwa ntchito pazinthu zomwe zimafuna mawonekedwe apadera komanso kulekerera kwa mawonekedwe.
Ntchito zomwe anthu ambiri amagwiritsa ntchito popanga chitsulo chozizira zimaphatikizapo zida zomangira, mipando yachitsulo, zipangizo zapakhomo, zida zamagalimoto ndi ntchito zaukadaulo komwe kumafunika kulondola kapena kukongola.
3. Magiredi a Zitsulo Zotentha Zozungulira
Chitsulo chotenthedwa chimapezeka m'magiredi angapo kuti chikwaniritse zofunikira za polojekiti yanu. Bungwe la American Society for Testing and Materials (ASTM) kapena Society of Automotive Engineers (SAE) limakhazikitsa miyezo ndi magiredi malinga ndi kapangidwe ndi luso la chitsulo chilichonse.
Magiredi achitsulo a ASTM amayamba ndi chilembo "A" chomwe chimayimira zitsulo zachitsulo. Dongosolo lowerengera la SAE (lomwe limadziwikanso kuti American Iron and Steel Institute kapena dongosolo la AISI) limagwiritsa ntchito nambala ya manambala anayi pogawa. Magiredi achitsulo cha kaboni wamba mu dongosololi amayamba ndi manambala 10, kutsatiridwa ndi manambala awiri osonyeza kuchuluka kwa kaboni.
Izi ndi mitundu yodziwika bwino ya chitsulo chokulungidwa ndi kutentha. Dziwani kuti zinthu zina zimapezeka m'njira ziwiri zokulungidwa ndi kutentha komanso kuzizira.
A36 Chitsulo Chotentha Chozungulira
Chitsulo cha A36 chotenthedwa ndi chimodzi mwa zitsulo zotenthedwa kwambiri zomwe zimapezeka (chimapezekanso mu mtundu wozizira, womwe ndi wocheperako). Chitsulo chotsika cha kaboni ichi chimakhala ndi mpweya wochepa wa kaboni wochepera 0.3%, 1.03% manganese, 0.28% silicon, 0.2% mkuwa, 0.04% phosphorous, ndi 0.05% sulfure. Ntchito zodziwika bwino za A36 zitsulo zimaphatikizapo:
Mafelemu a galimoto
Zipangizo zaulimi
Mashelufu
Njira zoyendera anthu oyenda pansi, malo oimikapo magalimoto, ndi zitsulo zotetezera
Thandizo la kapangidwe ka nyumba

1018 Chitsulo Chotentha Chozungulira cha Carbon
Pafupi ndi A36, AISI/SAE 1018 ndi imodzi mwa mitundu yodziwika bwino yachitsulo. Kawirikawiri, mtundu uwu umagwiritsidwa ntchito m'malo mwa A36 pamitundu ya bar kapena strip. Zipangizo zachitsulo za 1018 zimapezeka mumitundu yonse yozungulira yotentha komanso yozizira, ngakhale kuti yozungulira yozizira imagwiritsidwa ntchito kwambiri. Mitundu yonseyi ili ndi mphamvu komanso kuuma kuposa A36 ndipo ndi yoyenera kwambiri pa ntchito zopanga zozizira, monga kupindika kapena kugwedeza. 1018 ili ndi 0.18% yokha ya kaboni ndi 0.6-0.9% ya manganese, yomwe ndi yochepera A36. Ilinso ndi zotsalira za phosphorous ndi sulfure koma zodetsa zochepa kuposa A36.
Ntchito zachitsulo za 1018 zimaphatikizapo:
Magiya
Nkhope
Ma Ratchet
Zipangizo zamafuta
Mapini
Mapini a unyolo
Ma Liners

Mapini opachika
1011 Chitsulo Chotentha Chokulungidwa
1011 Chitsulo chokulungidwa ndi mbale chotentha chimapereka malo olimba kuposa chitsulo chokulungidwa ndi mbale chozizira. Chikakulungidwa ndi galvanized, chimagwiritsidwanso ntchito pamene kukana dzimbiri kuli kofunikira. Chitsulo cholimba kwambiri komanso cholimba kwambiri cha HR ndi mbale n'zosavuta kuboola, kupanga ndi kusungunula. Chitsulo chokulungidwa ndi mbale chotentha chimapezeka ngati chokulungidwa ndi kutentha kapena chokulungidwa ndi kutentha.
Zina mwa zabwino zomwe zimagwiritsidwa ntchito ndi 1011 hot rolled steel sheet and plate ndi monga kusinthasintha kwa malleable, kupanga kwakukulu, komanso kutsika poyerekeza ndi kuzizira.

Chitsulo Chotentha Chozunguliridwa ndi ASTM A513
Mafotokozedwe a ASTM A513 ndi a machubu achitsulo cha kaboni chotenthedwa. Machubu achitsulo chotenthedwa amapangidwa podutsa chitsulo chotenthedwa kudzera m'ma rollers kuti akwaniritse miyeso yeniyeni yeniyeni. Chogulitsacho chimakhala ndi mawonekedwe ozungulira okhala ndi ngodya zozungulira komanso kapangidwe kolumikizidwa kapena kopanda msoko. Chifukwa cha izi, chubu chachitsulo chotenthedwa ndi choyenera kwambiri kugwiritsa ntchito chomwe sichifuna mawonekedwe enieni kapena kulekerera kolimba.
Chitoliro chachitsulo chotenthedwa ndi chosavuta kudula, kupotoza, kupanga, ndi makina. Chimagwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikizapo:
Zomangira injini
Zitsamba
Kumanga nyumba/zomangamanga
Magalimoto ndi zida zina (mathirakitala, ndi zina zotero)
Zipangizo zamafakitale
Mafelemu a solar panel
Zipangizo zapakhomo
Ndege/mlengalenga
Zipangizo zaulimi
Chitsulo Chotentha Chozunguliridwa ndi ASTM A786
Chitsulo chotenthetsera cha ASTM A786 chimakhala chotenthetsera kwambiri komanso champhamvu kwambiri. Chimapangidwa nthawi zambiri kuti chigwiritsidwe ntchito pa mbale zopondaponda zachitsulo pa ntchito zotsatirazi:
Pansi
Njira Yokwerera
1020/1025 Chitsulo Chotentha Chokulungidwa
Chitsulo cha 1020/1025, chomwe chimagwiritsidwa ntchito kwambiri pa ntchito zomanga ndi uinjiniya, chimagwiritsidwa ntchito kwambiri pa ntchito zotsatirazi:
Zida ndi ma dies
Zigawo za makina
Zipangizo zamagalimoto
Zipangizo zamafakitale
Ngati mukuganiza zogula cholembera chotentha, pepala lopindika lotentha, cholembera chopindika chozizira, mbale yopindika yozizira, onani njira zomwe JINDALAI ili nazo ndipo ganizirani kulumikizana ndi gulu lathu kuti mudziwe zambiri. Tikupatsani yankho labwino kwambiri pa ntchito yanu. Chonde musazengereze kutilankhulana nafe.
