Q: Dab tsi yog cov nyhuv ntawm cov khaub thuas uas muaj cov pa hluav taws xob siab?
A: {1. hloov pauv hauv cov qauv thiab cov khoom
Cementite faib: Tus qauv ua kom cov txiv neej ua kom nruj me ntsis rau hauv cov ferrite, thiab tau npaj kho dua tshiab (HV nce ntxiv rau lub xeev kub rau} .
Ua haujlwm hnyav rhiab: Cov ntsiab lus carbon: Ntau dua cov haujlwm hardening index, thiab brittleness nce tom qab txias dolling . 2. Kev Siv Kev Siv Tau
Cov txiaj ntsig zoo: Tom qab dov tawm, nws tuaj yeem siv ncaj qha rau cov kab mob steel (xws li cov khoom siv tawv hlau) thiab cov cuab yeej zoo ntawm cov yam ntxwv siab siab {}}
Precision Txias Rolling (xws li txias rolled strip steel) tuaj yeem tswj hwm lub thickness rawb hlau) tuaj yeem tswj hwm lub thickness divance ntawm ± 01mm kom tau raws li cov kev xav tau ntawm qhov chaw ntsuas.
Cov kev txwv: Tus nqi txo tus nqi them dhau yuav tsum tau nruj me ntsis tswj (ib qho dhau tsawg dua lossis sib npaug li 15%) kom tsis txhob muaj ntug kev tawg;
Spheriding annealing (kub750-780} degree) yog xav tau tom qab kev txiav kev txiav, txwv tsis pub cov cuab yeej yooj yim los hnav.
Q: Cov ntaub ntawv dab tsi txias txias tau muaj ntawm cov hlau qis?
A: {1. hloov pauv hauv cov qauv thiab cov khoom
Qhov cuam tshuam ntawm alloy ntsiab: mn, si thiab lwm yam kev daws teeb meem tau zog dua li ntawm cov hlau tsis muaj zog ntxiv tau {} .
Tej zaum theem hloov: Cov hlau muaj CR, mo thiab lwm yam me me yuav ua rau lub martensite me me tom qab dov tawm, nce brittleness .
2. Kev Siv Kev Siv
Cov txiaj ntsig: Muaj lub zog muaj zog yog tsim nyog rau cov txheej txheem (xws li cov txheej txheem txias (nrog rau kev siv lub zog sai sai
Cov kev txwv: kev nyuaj siab nyem annealing (kub500-600}}}} degree) yog xav tau tom qab kev sib tsoo sab hauv thiab tiv thaiv kev laus; Weldability txo qis dua nrog kev kho kom muaj kev kho mob ntau ntxiv, thiab kev kho kom preheatst yog yuav tsum tau .
Q: Cov ntaub ntawv dab tsi txias txias muaj ntawm stainless hlau?
A: {1. hloov pauv hauv cov qauv thiab cov khoom
Colding ciab ua rau strain-indassed marticitic hloov ntawm Austenite muaj zog thiab hardness, tab sis me ntsis txo corrosion tsis kam {}}
Tom qab dov tawm, cov nplej ntawm cov hlau hluav taws xob ferritic yog kho kom zoo nkauj (xws li sib sib zog nqus cov tog (xws li chav ntxuav cov dej sib sib zog nqus (xws li chav ntxuav cov dej sib sib zog nqus (xws li chav ntxuav tais diav (xws li chav ua noj cov tog).
2. Kev Siv Kev Siv
Tom qab dov tawm, lub roughness ro tsawg dua lossis sib npaug ntawm cov qauv zoo nkauj (xws li rov ua kom zoo dua li kev kho kom haum (}}
Q: Dab tsi yog cov txiaj ntsig txias txias muaj nyob ntawm silicon steel?
A: {1. hloov pauv hauv cov qauv thiab cov khoom
Cov kab ke kev tswj hwm: Khaub thuas yob + annealing tuaj yeem tsim ib gossian kev ntxhib los mos ({110}<001>), Txhim kho ntau yam kev sib nqus sib nqus permeability thiab txo cov hlau poob .
Decarburization treatment: After cold rolling, high temperature annealing (900-1100℃) is required to decarburize to a carbon content of<=0.003% to prevent carbides from hindering the movement of magnetic domains.
2. Kev Siv Kev Siv
Cov khaub thuas-lub ntsuas cua (0.1-0.35 mm) Silicon steel yog cov khoom siv tseem ceeb thiab hloov pauv {}}
Txwv tsis pub:
Thaum lub sij hawm dov, qhov tseeb ntawm cov menyuam sab nraud yuav tsum nruj me ntsis tswj kom tsis txhob muaj kev puas tsuaj rau cov txheej txheem insulating; Cov khoom tiav tau ua tiav yuav tsum tau coated los tiv thaiv cov kab luv luv ntawm cov nplooj ntawv .
