Seamless steel raj rau Thaum tshav kub kub exchanger / Boiler yeeb nkab
Khoom nthuav qhia
quenching (Hardening, tseem hu ua quenching) - yog lub siab kub boiler raj sib npaug rhuab mus rau qhov tsim nyog kub, thiab ces sai sai rau hauv dej los yog roj nyob rau hauv ceev txias, los yog nyob rau hauv cov huab cua los yog freezing cheeb tsam txias, kom lub siab kub boiler. raj kom tau qhov xav tau hardness.
Tempering-siab siab boiler yeeb nkab yuav nkig tom qab quenching.Nyob rau tib lub sijhawm, qhov kev ntxhov siab tshwm sim los ntawm quenching thiab txias tuaj yeem rhuav tshem lub siab kub boiler yeeb nkab los ntawm lub teeb tshuab.Txhawm rau tshem tawm cov brittleness, txoj kev kho tempering tuaj yeem siv.Refire yog rov ua kom lub siab kub boiler raj rau qhov tsim nyog kub lossis xim, thiab tom qab ntawd muab qhov txias txias.Txawm hais tias lub hardness ntawm lub siab siab boiler yeeb nkab yog txo me ntsis, nws muaj peev xwm ua kom lub toughness ntawm lub siab kub boiler yeeb nkab thiab txo nws brittleness.
Annealing-annealing yog txoj hauv kev los tshem tawm cov kev ntxhov siab sab hauv thiab cov hlau ntawm lub siab kub boiler yeeb nkab.Txoj kev Annealing yog kom sov cov hlau qhov chaw rau qhov kub thiab txias, thiab tom qab ntawd muab tso rau hauv cov hmoov tshauv qhuav, txiv qaub, asbestos los yog kaw rau hauv qhov cub, ua kom nws maj mam txias.
Hardness (Hardness) - yog lub peev xwm ntawm cov khoom siv los tiv thaiv kev nkag mus rau sab nraud.Lub hardness tester yog qhov tseeb heev, uas yog ib txoj hauv kev los sim hardness.Txoj kev sim siv feem ntau yog Rockwell hardness test Rockwell hardness test tshuab siv qhov tob ntawm lub pob zeb diamond rushed rau hauv cov hlau los txiav txim siab qhov nyuaj ntawm lub siab kub boiler yeeb nkab, qhov loj dua qhov tob tob, qhov me me hardness.Lub pob zeb diamond rushes mus rau hauv qhov tob ntawm cov hlau los qhia qhov tseeb tus lej ntawm tus taw tes, uas yog hu ua Rockwell hardness tooj.
Forging-yog lub rauj ua kom cov hlau ua ib yam zoo <molding & gt;txoj kev, thaum lub siab kub boiler raj cua kub rau forging kub, tuaj yeem koom nrog forging, dabtsi yog khoov, kos duab, molding thiab lwm yam haujlwm.Feem ntau cov high-pressure boiler raj yog ib qho yooj yim rau forge thaum rhuab rau ci cherry liab.
Britittleness-qhia qhov xwm txheej ntawm kev kub siab boiler yeeb nkab yooj yim rau rupture, cam khwb cia hlau yog nkig, txawm poob rau hauv av yuav rupture.Britittleness thiab hardness yog zoo sib xws, siab hardness ntawm 20 # precision steel yeeb nkab feem ntau kuj yog brittleness.
ductility- (tseem hu ua softness) yog qhov xwm ntawm hlau mus tas li deformation los ntawm sab nraud quab yuam yam tsis muaj fragmentation, ductility ntawm siab kub boiler yeeb nkab yuav rub mus rau hauv nyias kab.
Elastic-yog cov cuab yeej ntawm lub siab kub boiler raj deformed los ntawm sab nraud quab yuam, thaum lub sab nraud quab yuam raug tshem tawm.Caij nplooj ntoos hlav steel yog cov khoom siv elastic heev.
Hardness-yog hlau tsis kam mus rau sab nraud puncture los yog txiav yuav ua rau kom lub siab kub boiler raj hardness ntau txoj kev yog quenching.
Kev ua tau zoo- -tseem hu ua malleability, yog lwm qhov sawv cev ntawm cov hlau ductility lossis softness.Exhibition yog ib yam khoom ntawm hlau txais rauj forging los yog dov.
Toughness yog lub peev xwm ntawm kev kub siab boiler yeeb nkab kom tiv taus kev co los yog cuam tshuam.Lub toughness yog qhov opposite ntawm brittleness.
Nyob rau hauv cov txheej txheem ntawm seamless steel yeeb nkab rau boiler, kev kho cua sov yog cov txheej txheem tseem ceeb.Kev kho cua sov muaj qhov cuam tshuam tseem ceeb rau qhov zoo ntawm sab hauv thiab qhov chaw zoo ntawm seamless steel yeeb nkab, uas yog qhov tseem ceeb tshwj xeeb rau kev tsim cov hlau alloy seamless steel yeeb nkab.
Peb lub tuam txhab txais kev kho cua sov uas tsis yog oxidation, kev tsim cov kav hlau steel nrog lub koom haum metallographic ruaj khov thiab zoo sab hauv thiab sab nrauv zoo, siv eddy tam sim no thiab ultrasonic tsis siv neeg qhov tsis pom kev, cov yeeb nkab steel ib los ntawm ib qho rau eddy tam sim no qhov teeb meem nrhiav pom thiab ultrasonic flaw detection.Nrog ultrasonic thickness ntsuas thiab oblique qhov tsis pom kev ua haujlwm, nws tuaj yeem kuaj xyuas cov txheej txheem tsis xws luag hauv cov yeeb nkab steel.
