Lub raje seamless steel raj tsim tawm me me qhia qhov kev faib tawm tshwj xeeb thiab ua haujlwm ntawm cov raj roj carbon hlau.
1. General Carbon Steel Tube
Feem ntau, hlau nrog cov ntsiab lus carbon 0,25% yog hu ua cov hlau roj carbon. Lub annealed qauv ntawm cov hlau roj carbon cov roj av yog ferrite thiab ib qho me me ntawm cov hlawsite. Nws muaj lub zog tsawg thiab hardness, zoo plastent thiab todualness, thiab yog yooj yim, Forging thiab 20cr hlau tau siv dav. Cov hlau muaj qee lub zog. Tom qab quenching thiab tempering ntawm tsawg kub, cov hlau no muaj cov khoom siv nyuaj heev, qhov zoo ntawm kub kub nyuaj, thiab temper brittleness tsis pom tseeb.
Siv:Hauv kev tsim khoom machinery tsim kev lag luam, nws yog qhov tsim nyog rau kev ua welded txheej txheem ntawm cov txheej txheem thiab cov seem uas tsis muaj kev ntxhov siab tom qab forging, kub stamping thiab machining. Nyob rau hauv lub tshuab turnine thiab boiler Raug Kev Lag Luam, feem ntau yog siv rau cov kav dej, flanges, thiab lwm yam uas ua haujlwm hauv cov xov xwm tsis yog-corrosive. Headers thiab ntau yam fasteners; kuj haum rau kev tsim cov me me thiab nruab nrab-cov hlua khi, xws li cov kab mob sib tw, thiab cov kab mob thev naus laus zis Hauv qhov hnyav thiab nruab nrab-tsim machinery tsim, xws li forged lossis nias khi cov pas nrig, shackles, cov tes tsho, conttures, thiab lwm yam.
2. Cov raj roj carbon tsawg
Tsawg-carbon steel: Cov hlau roj carbon tsawg nrog cov ntsiab lus carbon ntau dua 0.15% yog siv rau hauv cov nyom, thiab qee cov yas pwm, thiab cov khoom siv zoo thiab tsis muaj kub. Cheebtsam. Tom qab carburizing thiab quenching thiab qis-kub fertensite, cov qauv ntawm cov pa roj martens ntawm qhov chaw siab thiab cov khoom siv tsawg dua thaum lub chaw nruab nrab muaj siab heev. Lub zog zoo thiab muaj kev nruj. Nws yog qhov haum rau kev ua khau nres, las shafts, kab mob balancer ntawm cov tsheb laij teb, pob tw bushes ntawm balancers, tes, conttures thiab lwm feem.
3. Nruab nruab nrab ntawm cov raj roj carbon steel
Nruab nrab-Carbon Steel: Carbon Steel nrog cov ntsiab lus carbon ntawm 0.25% rau 0.60%. 30, 35, 405, 50, 55 thiab lwm cov qib nyob rau hlau carbon. Vim tias cov ntsiab lus pearlite hauv cov hlau nce, nws lub zog thiab hardness yog siab dua ua ntej. Hardness tuaj yeem nce siab dua tom qab quenching. Ntawm lawv, 45 hlau yog qhov feem ntau. 45 hlau yog lub siab-zog nruab nrab-carbon quenched thiab tempered steel, uas muaj qee yam kev ua tau zoo thiab kev txiav txom nyem. Nws tuaj yeem tau txais cov cuab yeej siv kho tshuab zoo nkauj los ntawm kev ua kom sov thiab kev kho kom sov thiab ua kom tawv nqaij, tab sis nws cov tawv tawv tsis zoo. Nws yog siv los tsim qhov chaw nrog cov kev ua kom muaj zog siab thiab nruab nrab. Nws feem ntau yog siv nyob rau hauv quenched thiab tempered lossis ib txwm xeev. Txhawm rau ua kom cov steel muaj qhov tsim nyog ua kom nruj thiab tshem tawm nws cov kev ntxhov siab uas seem, cov hlau yuav tsum tau ua kom ntev thiab ua rau tembed.
