Kev tsim cov khoom siv hlau feem ntau suav nrog txoj hauv kev xws li dov, forging, kos duab, thiab extrusion. Ntawm cov no, extrusion yog cov txheej txheem tseem ceeb uas muaj zog txhua yam siv rau deform steel billets, tsim cov khoom tiav ntawm qhov ntau thiab tsawg thiab cov duab. Lub ntsug hlau extruder yog ib qho loj - nplai ntawm cov cuab yeej tshwj xeeb tsim los rau extrusion ntawm hlau, tshwj xeeb tshaj yog rau kev tsim cov tuab - cov kav dej seamless steel.
Cov txheej txheem Vertical Extrusion
Txoj kev ntsug extrusion pib nrog cam khwb cia hlau ingots li raw khoom. Cov ingots no tau ua kom sov, thiab cov nplai oxide raug tshem tawm ua ntej cov billets raug kaw - hom kev ntxhov siab thiab kev ua kom zoo ntawm cov khoom siv hluav taws xob - ua tshuab los ua cov raj xa hluav taws xob. Lub hollow raj billets yog ces rhuab rau ob lub sij hawm thiab xa mus rau hauv ntsug extruder. Lub tshuab no siv lub siab hnyav rau extrude cov hlau rau hauv cov kav dej lossis lwm yam profiles, shaping lawv raws li qhov yuav tsum tau ua.
Cov txheej txheem no tshwj xeeb tshaj yog siv rau siab -cov ntaub ntawv hlau alloy, uas suav nrog cov khoom xws li cobalt, nickel, manganese, thiab vanadium. Cov hlau no feem ntau siv los tsim cov tuab tuab tshwj xeeb- cov kav hlau uas muaj peev xwm tiv taus qhov chaw ua haujlwm hnyav uas muaj kev kub siab thiab kub.
Kev sib tw ntawm Extruding High-Alloy Steel
Kev tsim cov yeeb nkab steel no yuav tsum tau hais txog ntau yam kev sib tw. Kev taw qhia txog qib siab- cov khoom siv alloy txo cov dej ntws ntawm cov hlau thiab nce qhov kub thiab txias tshaj 1100 degree, ua rau cov txheej txheem extrusion nyuaj dua li thaum ua hauj lwm nrog cov hlau tsis yog -ferrous hlau xws li txhuas thiab tooj liab. Lub tonnage ntawm extruder, pwm cov ntaub ntawv, pwm tsim, thiab siab - lubricants kub yuav tsum tau ua tib zoo xaiv los xyuas kom meej extrusion ua tiav.
Kev siv cov yeeb nkab steel
Thick -cov kav hlau seamless uas tsim los ntawm ntsug hlau extruders yog qhov tseem ceeb hauv kev lag luam xws li thermal thiab nuclear fais fab. Hauv cov chaw tsim hluav taws xob, qhov kub thiab txias yuav tsum tau ua kom zoo dua kev siv hluav taws xob xav tau cov ntaub ntawv uas tuaj yeem tiv taus huab cua. Lub zog siab rau lub tshuab hluav taws xob tam sim no yog nyob ntawm 25 txog 31 MPa, nrog rau chav kub ntawm 580℃thiab 610 degree. Tom ntej no- tiam turbines yuav tsum ua haujlwm ntawm qhov kub siab tshaj 700℃thiab siab mus txog 35 MPa, ua rau kev siv cov kav dej zoo - zoo steel qhov tseem ceeb.
Ua ntej lub advent ntawm ntsug extruders, ib txwm txoj kev ntawm manufacturing loj - txoj kab uas hla, tuab -walled seamless steel kav nyob rau hauv Tuam Tshoj koom nrog forging steel rau hauv tuav thiab drilling qhov. Txoj kev no tsis muaj txiaj ntsig, khib nyiab, thiab raug nqi, vim nws xav tau ntau cov khoom siv thiab tsis ua raws li cov qauv siab ntawm cov tshuab turbine tshiab. Nrog ntsug extruders, cov kev cov nyom no tau kov yeej, thiab cov chaw tsim khoom tuaj yeem tsim cov kav dej uas muaj peev xwm tuav tau ultra-cov dej tsis zoo, qhov tseem ceeb rau cov chaw tsim hluav taws xob niaj hnub no.
Lwm qhov tseem ceeb ntawm cov kav dej seamless steel yog nyob rau hauv petrochemical thiab thee chemical industries, qhov loj -scale units xws li ethylene cov nroj tsuag thiab roj refineries yuav tsum tau siab - kub, siab - cov tshuaj tiv thaiv ib puag ncig. Cov chav loj no xav tau cov kav dej tuab -cov kav dej seamless steel los xyuas kom muaj kev nyab xeeb thiab kev thauj khoom zoo nyob rau hauv cov xwm txheej hnyav.
