peb tuaj yeem muab koj cov khoom lag luam zoo thiab cov kev daws teeb meem, tus nqi sib tw thiab kev txhawb nqa cov neeg yuav khoom zoo tshaj plaws.Peb lub hom phiaj yog "Koj tuaj ntawm no nrog kev nyuaj thiab peb muab rau koj luag nyav kom tshem tawm" rauTuam Tshoj Seamless Steel Yeeb Nkab thiab Alloy Seamless Steel Yeeb Nkab, Raws li ib txoj hauv kev los ua kom siv cov peev txheej ntawm kev nthuav dav cov ntaub ntawv thiab qhov tseeb hauv kev lag luam thoob ntiaj teb, peb txais tos cov kev cia siab los ntawm txhua qhov chaw ntawm lub vev xaib thiab offline.Txawm hais tias nyob rau hauv cov khoom zoo tshaj plaws peb muab, kev pabcuam kev sib tham zoo thiab txaus siab yog muab los ntawm peb pawg kws tshaj lij kev pabcuam tomqab muag.Cov npe tshuaj daws teeb meem thiab qhov tob tsis zoo thiab lwm yam ntaub ntawv weil raug xa tuaj rau koj raws sijhawm rau cov lus nug.Yog li xyuas kom koj tau txais kev sib cuag nrog peb los ntawm kev xa email rau peb lossis tiv tauj peb yog tias koj muaj kev txhawj xeeb txog peb lub tuam txhab.koj tuaj yeem tau txais peb qhov chaw nyob info los ntawm peb lub vev xaib thiab tuaj rau peb lub lag luam.los yog ib daim ntawv ntsuam xyuas ntawm peb cov kev daws teeb meem.Peb cia siab tias peb tau npaj los sib koom ua ke thiab tsim kom muaj kev sib raug zoo nrog peb cov phooj ywg hauv kev ua lag luam no.Peb tab tom tos ntsoov rau koj cov lus nug.
Qhov kev pabcuam kub yog 580 ℃, thiab cov phaj hlau yuav tsum muaj qhov kub thiab txias ua kom muaj zog.Cov hlau phaj yog xa hauv lub xeev normalized thiab tempered.12Cr1MoVG alloy yeeb nkab yog ua raws li cov pa roj carbon zoo, thiab ib lossis ob peb lub ntsiab lus hlau raug tsim nyog ntxiv los txhim kho cov khoom siv kho tshuab, toughness thiab hardenability ntawm cov hlau.Cov khoom ua los ntawm cov hlau no feem ntau xav tau kev kho cua sov (normalizing lossis quenching thiab tempering);Cov khoom thiab cov khoom ua los ntawm lawv feem ntau yuav tsum tau quenching thiab tempering los yog deg tshuaj kho (carburizing, nitriding, thiab lwm yam), nto quenching los yog high-frequency quenching ua ntej siv.Yog li, raws li cov tshuaj sib txawv (feem ntau yog cov ntsiab lus carbon), cov txheej txheem kev kho cua sov thiab kev siv, cov hlau no tuaj yeem muab faib ua carburized, quenched thiab tempered thiab nitrided steels.
Ua ntej, nws tuaj yeem ua 100% rov ua dua tshiab, txuag hluav taws xob thiab kev tiv thaiv ib puag ncig.
Thib ob, nws muaj plasticity siab heev thiab tuaj yeem siv rau kev tsim khoom thiab kev ua haujlwm thib ob.
Thib peb, nws muaj qhov zoo thermal conductivity thiab siab kub creep peev xwm.
Plaub, nws muaj oxidation zoo thiab corrosion kuj.
Thib tsib, nws muaj kev ua haujlwm txias thiab kub ua haujlwm zoo.
12Cr1MoVG yog ib hom chromium molybdenum alloy steel yeeb nkab, nyob rau hauv uas lub ntsiab tshuaj Cheebtsam yog carbon 0.08-0.15, silicon 0.17-0.37, manganese 0.40-0.70, phosphorus tsis ntau tshaj 0.035, sulfur tsis ntau tshaj 0.20.0.0.0.0.0.0. molybdenum 0.25-0.35, alum 0.15-0.30, thiab lwm yam.
Ua ntej, nws yog tsuas yog siv los tsim cov high-pressure alloy raj rau cua sov qhov chaw ntawm cov dej raj boilers nrog siab siab thiab saum toj no.
Qhov thib ob, nws yog dav siv nyob rau hauv superheaters, headers thiab lub ntsiab chav ducts ntawm domestic high-pressure, ultra-siab siab thiab subcritical fais fab chaw nres tsheb boilers.
Thib peb, txoj kab uas hla loj yog siv los ua headers thiab Main Steam Conduits nrog chav ntsuas hauv qab 565 ℃.
Ua ntej, kub dov (extrusion seamless steel yeeb nkab) txheej txheem ntws:
Round tube billet → cua sov → tho → peb yob cross dov, nruam dov los yog extrusion → yeeb nkab stripping → sizing (los yog txo) → txias → billet → straightening → hydrostatic test (los yog flaw detection) → marking → warehousing.
Thib ob, kos duab txias (dov) seamless steel yeeb nkab txheej txheem ntws:
Round tube billet → cua sov → tho → taub hau → annealing → pickling → roj txheej (tooj liab plating) → multi pass txias drawing (txias dov) → billet raj → tshav kub kho → straightening → hydrostatic test (los yog flaw detection) → marking → warehousing.
