Nyob rau hauv kev lag luam niaj hnub no, cov kav dej yeeb nkab tau siv dav hauv cov khoom siv dej, cov dej ntws, cov pa xa hluav taws xob thiab lwm yam kev lag luam vim lawv cov khoom siv zoo heev thiab kev tiv thaiv corrosion. Txhawm rau kom ntseeg tau qhov zoo thiab kev ntseeg siab ntawm cov kav hlau kav hlau, lawv cov txheej txheem tsim khoom yuav tsum tau tswj xyuas nruj thiab ua kom zoo. Los ntawm kev npaj thiab spheroidization ntawm molten hlau, mus rau centrifugal casting, annealing, thiab tiav cov txheej txheem xws li zinc txau, sib tsoo, hydraulic siab kuaj, cement hauv ob sab phlu thiab asphalt txau, txhua qhov txuas yog qhov tseem ceeb. Kab lus no yuav qhia txog cov txheej txheem tsim khoom ntawmDuctile Cam khwb cia hlau yeeb nkabhauv kev nthuav dav, thiab qhia yuav ua li cas kom ntseeg tau tias txhua lub yeeb nkab tuaj yeem ua tau raws li cov qauv thoob ntiaj teb thiab kev siv tiag tiag los ntawm kev tswj hwm kev tshawb fawb thiab cov txheej txheem thev naus laus zis, thiab muab kev ruaj ntseg kev ruaj ntseg lav rau ntau yam haujlwm engineering.
1. Kev npaj ntawm Molten Hlau
Molten Hlau Npaj thiab Spheroidization: Xaiv qhov zoo tshaj plaws casting npua hlau ua raw khoom, xws li zoo ductile casting npua hlau, uas muaj cov yam ntxwv ntawm qis P, qis S, thiab qis Ti. Raws li cov specifications ntawm cov yeeb nkab txoj kab uas hla yuav tsum tau tsim, cov ntaub ntawv raw khoom yog ntxiv rau nruab nrab zaus hluav taws xob rauv, uas modulates lub molten hlau thiab heats nws mus rau qhov kub uas yuav tsum tau los ntawm tus txheej txheem, thiab ces ntxiv spheroidizing tus neeg sawv cev rau spheroidization.
Kub Hlau Zoo Tswj: Nyob rau hauv tus txheej txheem ntawm molten hlau npaj, qhov zoo thiab kub ntawm txhua qhov txuas yog nruj me ntsis tswj. Txhua lub cub tawg thiab txhua lub hnab ntawm cov hlau molten yuav tsum tau soj ntsuam los ntawm kev nyeem ntawv ncaj qha los xyuas kom meej tias cov hlau molten ua tau raws li qhov yuav tsum tau ua.
2. Centrifugal Casting
Dej-txias Hlau Pwm Centrifuge Casting: Dej-txias hlau pwm centrifuge yog siv rau casting. High-temperature molten hlau yog txuas ntxiv mus rau hauv high-speed rotating yeeb nkab pwm. Nyob rau hauv qhov kev txiav txim ntawm lub zog centrifugal, cov hlau molten yog sib npaug ntawm cov phab ntsa sab hauv ntawm cov yeeb nkab pwm, thiab cov hlau molten yog sai sai solidified los ntawm cov dej txias los ua ib tug ductile hlau yeeb nkab. Tom qab qhov kev ua tiav tiav, cov yeeb nkab cam khwb cia tau tshuaj xyuas tam sim ntawd thiab ntsuas qhov tsis xws luag los xyuas kom meej qhov zoo ntawm txhua cov yeeb nkab.
Kev kho mob Annealing: Cov castHlau TubeTom qab ntawd muab tso rau hauv lub qhov cub annealing rau annealing kev kho mob kom tshem tawm cov kev ntxhov siab sab hauv tsim thaum lub sij hawm casting txheej txheem thiab txhim kho cov qauv metallographic thiab mechanical zog ntawm cov yeeb nkab. cov
Kev Ntsuas Kev Ua Haujlwm: Tom qab annealing, ductile hlau yeeb nkab yuav raug mus rau ib tug series ntawm kev ntsuam xyuas nruj, xws li indentation test, zoo li cas, flattening test, tensile test, hardness test, metallographic test, thiab lwm yam. Cov kav dej uas tsis ua raws li cov kev cai yuav raug muab pov tseg thiab yuav tsum tsis txhob nkag mus rau hauv cov txheej txheem tom ntej.
3. Kev ua tiav
Zinc Txau: Cov yeeb nkab hlau yog kho nrog zinc los ntawm kev siv lub tshuab hluav taws xob hluav taws xob siab. Cov txheej zinc tuaj yeem tsim cov yeeb yaj kiab tiv thaiv ntawm qhov chaw ntawm cov yeeb nkab txhawm rau txhim kho corrosion kuj ntawm cov yeeb nkab. cov
Sib tsoo: Tsim nyogIron Drainage Piperaug xa mus rau qhov chaw sib tsoo thib peb rau kev tshuaj ntsuam xyuas, thiab lub qhov (socket), spigot thiab sab hauv phab ntsa ntawm txhua cov yeeb nkab yog polished thiab ntxuav kom huv si kom huv si thiab ua tiav ntawm cov yeeb nkab nto thiab sealing ntawm lub interface.
Hydrostatic Test: Cov kav dej kho tau raug kuaj hydrostatic, thiab qhov ntsuas siab yog 10kg / cm² siab dua li ISO2531 tus qauv thoob ntiaj teb thiab European tus qauv, txhawm rau xyuas kom meej tias cov kav dej tuaj yeem tiv taus qhov siab txaus thiab ua tau raws li qhov xav tau ntawm kev siv tiag tiag. cov
Cement Lining: Sab hauv phab ntsa ntawm cov yeeb nkab yog centrifugally coated nrog cov cement los ntawm ob lub chaw nres tsheb cement hauv ob sab phlu. Cov cement mortar siv tau raug soj ntsuam nruj thiab tswj qhov sib piv. Tag nrho cov txheej txheem txheej yog tswj los ntawm lub khoos phis tawj los xyuas kom meej qhov zoo sib xws thiab ruaj khov ntawm cov cement hauv ob sab phlu. Cov kav dej uas muaj cov cement yog kho raws li qhov yuav tsum tau ua kom tag nrho cov cement hauv ob sab phlu. cov
Asphalt Txau: Cov kav dej kho yog thawj zaug rau ntawm qhov chaw, thiab tom qab ntawd asphalt yog txau los ntawm ob lub chaw nres tsheb tsis siv neeg txau. Lub asphalt txheej ntxiv ua rau muaj peev xwm tiv thaiv corrosion ntawm cov kav dej thiab txuas ntxiv lub neej kev pab cuam ntawm cov kav dej. cov
Kev soj ntsuam zaum kawg, ntim thiab khaws cia: Cov kav dej uas tau txau nrog asphalt raug kuaj xyuas zaum kawg. Tsuas yog cov kav dej tsim nyog tuaj yeem txau nrog cov cim, thiab tom qab ntawd ntim thiab khaws cia raws li qhov xav tau, tos kom xa mus rau ntau qhov chaw siv.
