Hluav taws xob steel yog dab tsi?
Hluav taws xob cov hlau yog ib hom tshwj xeeb ntawm cov hlau alloy tsim los siv rau hauv kev tsim hluav taws xob, transformers, thiab lwm yam khoom siv hluav taws xob. Nws yog tsim los ntawm kev sib xyaw ntawm cov hlau thiab silicon, muab nws ib qho tshwj xeeb ntawm cov yam ntxwv uas ua rau nws zoo tagnrho rau siv hauv cov khoom siv hluav taws xob.
Tsis zoo li cov hlau zoo tib yam, cov hlau hluav taws xob tau tsim los ua cov khoom siv hluav taws xob zoo heev, txhais tau tias nws tuaj yeem nqa hluav taws xob zoo. Qhov no ua rau nws yog ib qho khoom siv tseem ceeb rau txhua yam khoom siv uas xav tau hluav taws xob, xws li cov motors thiab transformers.
Cov yam ntxwv ntawm hluav taws xob steel
Hluav taws xob hlau yog ib qho hlau alloy ntawm hlau thiab carbon
Hluav taws xob cov hlau yog ib qho muaj zog, sib sib zog nqus hlau uas tuaj yeem siv rau ntau daim ntawv thov. Nws muaj lub siab elastic modulus, uas ua rau nws muaj zog tab sis tseem ductile txaus los ua hauj lwm rau hauv cov duab sib txawv. Nws muaj kev tiv thaiv siab thiab sib nqus permeability, thiab tsis yog magnetic thiaj li tsis cuam tshuam nrog hluav taws xob. Nws muaj qhov thermal expansion tsawg, uas txhais tau hais tias nws tsis nthuav lossis cog lus yooj yim nrog kev hloov pauv hauv qhov kub thiab txias zoo li lwm cov hlau ua. Thaum txias sai sai hauv dej lossis roj, cov hlau yuav nyuaj dua yog tias maj mam txias ntawm chav tsev kub.
Nws muaj siab magnetic permeability
Nws yog dav siv nyob rau hauv electromagnetic cuam tshuam shielding thiab magnetic cores. Hluav taws xob cov hlau kuj muaj hluav taws xob tiv taus siab thiab lub zog dielectric, ua rau nws cov khoom siv rau cov khoom siv hluav taws xob. Nws yog heev resistant rau corrosion los ntawm ntau yam acids thiab cov kuab tshuaj. Yog li ntawd, nws yog feem ntau xaiv cov hlau nyob rau hauv cov xwm txheej uas muaj corrosive gases yuav tsis muaj teeb meem. Hluav taws xob cov hlau tuaj yeem kho cua sov kom muab cov qib hardness ntau dua yam tsis muaj kev cuam tshuam rau nws qhov toughness lossis ductility.
Nws muaj tsawg coercivity
Nws muaj qis coercivity, yog resistant rau corrosion thiab tsis magnetic. Qhov saum npoo muaj lub siab hardness thiab tuaj yeem ua haujlwm-hardened los ntawm quenching cov khoom. Lub weldability ntawm cov hlau txhim kho thaum nws yog austenitized los ntawm cua sov mus rau 1200 degrees Celsius rau peb teev thiab txias maj mam. Hluav taws xob hlau yog siv nyob rau hauv transformers, low voltage cables, busbars, generators, vuam electrodes thiab contactors.
Nws yog siv nyob rau hauv transformer cores
Hluav taws xob cov hlau yog ib hom hlau alloy uas muaj ntau dua ductile thiab tiv taus ntau dua rau kev tawg, kev sib xyaw ua ke uas ua rau nws tsim nyog siv rau hauv transformer cores. Nws feem ntau yog ua nrog cov ntsiab lus carbon ntawm 0.08-0.12%. Qhov nce hauv cov ntsiab lus carbon txo qis qhov kub ntawm qhov kub kom cov khoom tuaj yeem cam khwb cia thiab machined yooj yim. Cov ntsiab lus alloying muab cov khoom sib txawv rau cov hlau, xws li nce kev tiv thaiv corrosion los yog txhim kho tensile zog. Hluav taws xob hlau yog siv dav hauv kev tsim hluav taws xob, kev sib kis thiab cov khoom siv vim nws muaj peev xwm tiv taus ib puag ncig hnyav yam tsis muaj kev cuam tshuam kev ua haujlwm lossis kev ntseeg siab.
Nws yog siv nyob rau hauv electromagnets
Nws yog tsim los ntawm hlau, carbon, thiab lwm yam khoom uas tsis tau txheeb xyuas. Thaum nws rhuab mus rau qhov kub siab heev, ces cov carbon bonds nrog cov hlau atoms ua ferromagnetic domains. Ferromagnetic domains yog qhov twg tag nrho cov khoom sib nqus ntawm cov hlau hluav taws xob los ntawm. Cov ferromagnetic domains tuaj yeem ua kom zoo los yog misaligned. Lub misaligned domains tsim ib tug ntau ntau magnetism tshaj li aligned sawv daws yuav.
Hom hluav taws xob hlau
Grain-oriented hluav taws xob steel
Grain-oriented hluav taws xob steel, los yog GOES, yog lub zog siab qis-alloy structural qib ntawm steel. Nws yog ib hom EHS (hluav taws xob siab zog) hlau, uas kuj suav nrog manganese stainless hlau. Cov qib no yog siv rau cov khoom siv hluav taws xob xa mus thiab cov khoom xa tawm vim tias lawv muaj kev hnav zoo heev thiab kev tiv thaiv corrosion nrog rau zoo toughness nyob rau hauv lub tshav kub-cuam tshuam cheeb tsam thaum creep rupture. Cov qauv nplej hauv GOES muaj peev xwm ua kom muaj kev ntxhov siab ntau dua li cov pa roj carbon monoxide vim tias cov nplej ua kom muaj kev ntxhov siab los ntawm ib cheeb tsam mus rau lwm qhov.
Muaj ob hom GOES: cov nplej ib txwm thiab cov nplej rov qab. Ib txwm GOES yog tsim los ntawm kev ntxiv cov txhuas nrog npib tsib xee lossis manganese txhawm rau txo cov ntsiab lus carbon thiab ua kom nws ntxiv thaum khaws cov ductility thaum rov qab GOES yog tsim los ntawm kev tshem tawm tag nrho lossis qee cov npib tsib xee nrog manganese ntxiv kom muaj ductility tab sis qis hardness dua li qub mus.
Non-oriented semi-processed hluav taws xob hlau
Non-oriented semi-processed hluav taws xob steel yog hom feem ntau siv hauv kev faib hluav taws xob. Lawv yog tsim los ntawm ib tug sib tov ntawm alloying ntsiab, carbon thiab silicon. Lub ntsiab alloying txhais lub peev xwm hardening thiab cov pa roj carbon thiab silicon tswj cov nplej loj thiab lub zog. Cov hom no feem ntau raug kho kom sov kom muab lawv cov khoom xav tau rau lawv daim ntawv thov.
Non-oriented tag nrho cov txheej txheem hluav taws xob hlau
Lub Non-oriented tag nrho cov txheej txheem hluav taws xob hlau yog ib hom hluav taws xob hlau uas muaj kev ua haujlwm siab thiab corrosion tsis kam. Nws yog tsim los ntawm kev sib xyaw ua ke ntawm ferritic, martensitic, thiab austenitic nplej uas ua rau cov khoom siv nyob rau hauv ntau yam kev siv. Ib daim ntawv thov rau hom hlau no yog nyob rau hauv transformers vim nws muaj peev xwm tiv taus huab cua kub yam tsis tau tawg.
Kev siv hluav taws xob steel
Hluav taws xob cov hlau yog ib hom tshwj xeeb ntawm cov hlau siv hauv kev tsim cov khoom siv hluav taws xob xws li transformers thiab motors. Nws yog feem ntau hu ua "silicon steel" vim nws cov ntsiab lus silicon siab. Hluav taws xob hlau yog tsim los ntawm hlau, silicon, thiab lwm yam alloying ntsiab uas muab nws cov yam ntxwv tshwj xeeb.
Hluav taws xob hlautuaj yeem siv rau hauv ntau yam kev siv, xws li cov khoom siv hluav taws xob rau cov khoom siv tsheb thiab cov khoom siv hauv tsev. Nws tseem tuaj yeem siv rau hauv kev lag luam xws li vuam tshuab, traction motors, thiab elevator. Cov khoom siv hluav taws xob hlau ua rau nws muaj txiaj ntsig zoo rau ntau yam kev lag luam sib txawv.
