1. Dab tsi yog alloy steel yeeb nkab? Nws txawv li cas los ntawm cov yeeb nkab steel hlau zoo li cas?
Alloy Steel yeeb nkab yog ua los ntawm kev ntxiv ib lossis ntau dua alloy, nickel, thiab lwm yam) ua rau cov khoom siv chromium, thiab lwm yam.
Qhov txawv:
Kev sib xyaw: cov yeeb nkab steel hlau yog feem ntau yog cov hlau thiab carbon; Alloy Steel Yeeb Nkab muaj cov ntsiab lus ntxiv ntxiv.
Kev Ua Tau Zoo: Alloy Steel Yeeb muaj lub zog siab dua, kev kub siab dua \/ corrosion tsis kam, thiab yog haum rau cov chaw hnyav.
Tus nqi: Alloy Steel Yeeb Nkab feem ntau kim dua vim nws cov nyom complex.
2. Dab tsi yog cov khoom siv hlau nplaum sib xyaw hlau? Lawv siv yog dab tsi?
Chromium-Molybdenum hlau (xws li 15crmo, p91): tiv taus kub thiab kub siab, siv rau hauv cov roj hmab thiab petrochemical pipelines.
Nickel-based alloys (xws li inconel 625): resistant rau huab corrosion, siv hauv aerospace thiab marine engineering.
Stainless hlau (xws li 304, 316): muaj chromium thiab npib tsib xee, acid thiab alkali tsis kam, siv hauv cov khoom noj thiab khoom siv kho mob.
Tsawg alloy siab zog hlau (xws li Q345): Weldability zoo, siv nyob rau hauv cov tuam tsev thiab choj qauv.
3. Dab tsi yog cov cuab yeej ua haujlwm tseem ceeb rau cov kav hlau alloy steel?
Kub Rolling \/ Txias Rolling: Kub Rolling yog siv rau txoj kab uas lub cheeb pua loj dua phab ntsa kav; Txias dov muaj siab precision thiab du nto.
Vuam: Welded kav yog tsim los ntawm Erdov (Kuj yog vuam) lossis submerged arc vuam, uas muaj tus nqi tsawg tab sis me ntsis qis zog.
Cov txheej txheem seamam: ua los ntawm cov txheej txheem zoo nkauj, cov kos duab txias, thiab lwm yam, nrog cov khoom muaj zog muaj zog, siv rau kev kub siab ib puag ncig.
Kev Kho Cua sov: normizing, quenching, thiab lwm yam los txhim kho hardness lossis tawv.
4. Cov teeb meem twg yuav tsum tau them nyiaj rau thaum Vuam Alloy Steel Kave?
Preheating thiab post-cua sov: high alloy alloy alloy alloy alloy alloy alloy alloy alloy alloy alloy alloy alloy yuav tsum tau preheated los tiv thaiv cov kab nrib pleb, thiab txias txias tom qab vuam.
Vuam Khoom Siv Hluav Taws Xob: Xij Vuam Rods \/ xaim nrog cov khoom sib xyaw zoo sib xws rau cov khoom siv niam txiv (xws li} b2 vuam rods sib xws rau cov hlau chomium-molybdenum hlau).
Cov txheej txheem tswj: Tsawg hydrogen vuam, qis tam sim no txheej ntau ntau txheej los txo cov pa hluav taws.
Tshuaj Xyuas: X-Ray lossis Ultrasonic kev sim tshuaj yuav tsum tau tom qab vuam ua kom ntseeg tau tias tsis muaj qhov tsis pom zoo.
5. Yuav ua li cas kom raug xaiv cov khoom siv thiab cov lus qhia tshwj xeeb ntawm cov kav hlau alloy steel?
Cov hauv qab no yuav tsum tau txiav txim siab:
Nruab nrab thiab ib puag ncig: stainless hlau lossis cov npib tsib xee-ras alloys tau xaiv rau cov xov xwm corrosive; Chromium-molybdenum hlau yog xaiv rau qhov kub siab.
Siab \/ kub: Seamless kav kav tau xaiv rau cov xwm txheej siab, thiab lub zog loj yog kev txhawj xeeb rau ib puag ncig kub.
Txheem Cov Qauv: Ua raws li Astm (xws li A335), GB \/ T (xws li GB5310) thiab lwm yam qauv.
Kev lag luam efficiency: nyob rau hauv lub rooj sib tham ntawm lub rooj sib tham, muab cov kev ua ntej rau cov nqi nrog cov nqi qis dua (xws li Q345 hloov cov qib siab).
