Cov qauv hlau yog ib qho tseem ceeb hauv kev tsim kho kev lag luam, muab kev txhawb nqa tseem ceeb rau cov tsev, txuas hniav thiab ntau yam kev tsim kho vaj tse. Kev nkag siab txog ntau yam ntawm cov qauv steel yog qhov tseem ceeb rau cov engineers, architects thiab cov kws tshaj lij tsim kho kom ntseeg tau tias kev ua tau zoo thiab kev nyab xeeb ntawm lawv cov haujlwm.
Carbon Steel Structures:
Carbon steel yog ib qho ntawm cov khoom siv feem ntau siv hauv kev tsim vaj tsev vim nws lub zog siab, ua haujlwm ntev, thiab pheej yig. Nws feem ntau muaj hlau thiab carbon, nrog rau cov lej ntawm lwm cov ntsiab lus. Cov qauv carbon steel yog dav siv nyob rau hauv kev lag luam thiab cov tsev nyob, txuas hniav, thiab cov chaw ua lag luam.
High-Strength Low-Alloy (HSLA) Steel Structures:
HSLA steel muaj me me ntawm alloying ntsiab xws li tooj liab, npib tsib xee thiab vanadium, uas txhim kho nws cov khoom siv kho tshuab thaum tuav nws cov weldability thiab formability. Hom hlau no muaj qhov sib piv ntawm lub zog-rau-hnyav, ua rau nws tsim nyog siv rau hauv cov tsev siab siab, txuas txuas ntev thiab cov qauv hauv ntug dej hiav txwv, qhov twg qhov hnyav yog qhov tseem ceeb.
Forged Steel Structures:
Forged steel qauv yog tsim los ntawm cov txheej txheem ntawm shaping thiab compressing rhuab hlau rau hauv cov duab uas xav tau siv forging machinery. Txoj kev no txhim kho cov khoom siv ntawm cov hlau, nrog rau lub zog, ductility, thiab toughness. Forged steel Cheebtsam feem ntau yog siv rau hauv cov khoom siv hnyav xws li kev lag luam machinery, cranes, thiab cov qauv kev sib txuas uas yuav tsum tau muaj kev ntseeg siab.
Quenched thiab Tempered Alloy Steel Structures:
quenched thiab tempered alloy steel tau dhau los ua cov txheej txheem kev kho cua sov kom ua tiav cov khoom siv kho tshuab, suav nrog lub zog siab thiab hardness. Los ntawm kev ua kom txias txias txias txias (quenching) thiab tom qab ntawd rov ua kom sov rau qhov kub thiab txias (tempering), cov khoom tau txais kev ua kom tawv thiab tiv taus hnav thiab qaug zog. Hom hlau no yog tsim rau cov khoom siv uas muaj cov khoom hnyav, cuam tshuam thiab abrasive tej yam kev mob, xws li cov khoom siv mining, siab hlab ntsha thiab crane hooks.
Ntxiv nrog rau cov thawj hom no, muaj ntau yam tshwj xeeb ntawm cov qauv hlau uas haum rau cov kev siv tshwj xeeb, xws li huab cua steel rau cov qauv sab nraum zoov raug corrosion atmospheric, stainless hlau rau ib puag ncig uas yuav tsum tau tiv thaiv corrosion thiab staining, thiab hluav taws-resistant steel rau lub tsev. cov qauv yuav tsum tau txhim kho kev tiv thaiv hluav taws.
Kev nkag siab txog cov khoom thiab cov yam ntxwv ntawm ntau hom steel qauv ua rau cov kws tsim kho kev lag luam tuaj yeem txiav txim siab txog kev xaiv cov khoom, tsim kom zoo dua qub thiab kev ncaj ncees, thaum kawg ua rau muaj kev nyab xeeb, ua haujlwm tau zoo thiab ruaj khov ntawm qhov chaw tsim.
