Xov Xwm - Cov Txheej Txheem Tsim Cov Yeeb Nkab Hlau Uas Muaj Cov Khoom Siv: Cov Txheej Txheem Ua Kom Zoo Rau Cov Yeeb Nkab Zoo

Hauv kev tsim khoom lag luam niaj hnub no, cov kav hlau ductile tau siv dav hauv kev muab dej, dej ntws, roj xa mus thiab lwm qhov chaw vim lawv cov khoom siv zoo heev thiab kev tiv thaiv corrosion. Yuav kom ntseeg tau tias qhov zoo thiab kev ntseeg siab ntawm cov kav hlau ductile, lawv cov txheej txheem ntau lawm yuav tsum tau tswj hwm nruj thiab ua tiav zoo. Los ntawm kev npaj thiab spheroidization ntawm cov hlau molten, mus rau centrifugal casting, annealing, thiab cov txheej txheem tiav xws li zinc txau, sib tsoo, hydraulic siab sim, cement lining thiab asphalt txau, txhua qhov txuas yog qhov tseem ceeb. Tsab xov xwm no yuav qhia txog cov txheej txheem ntau lawm ntawmCov Yeeb Nkab Hlau Uas Muaj Cov Yeeb Nkab Uas Muaj Cov Khoom Siv ...kom meej, 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 cov kev xav tau siv tiag tiag los ntawm kev tswj hwm kev tshawb fawb thiab cov txheej txheem kev siv tshuab siab heev, thiab muab kev lees paub txog kev tsim kho vaj tse rau ntau yam haujlwm engineering.

1. Kev Npaj Hlau Uas Yaj Lawm
Kev Npaj Hlau Molten thiab SpheroidizationXaiv cov hlau npua zoo ua cov khoom siv raw, xws li cov hlau npua ductile zoo, uas muaj cov yam ntxwv ntawm P qis, S qis, thiab Ti qis. Raws li cov lus qhia ntawm lub raj txoj kab uas yuav tsim tawm, cov khoom siv raw sib xws raug ntxiv rau hauv lub cub hluav taws xob nruab nrab zaus, uas hloov cov hlau molten thiab ua kom sov rau qhov kub uas xav tau los ntawm cov txheej txheem, thiab tom qab ntawd ntxiv cov neeg sawv cev spheroidizing rau spheroidization.
Kev Tswj Xyuas Zoo ntawm Cov Hlau Kub: Hauv cov txheej txheem ntawm kev npaj hlau molten, qhov zoo thiab kub ntawm txhua qhov txuas raug tswj hwm nruj me ntsis. Txhua lub cub tawg thiab txhua lub hnab ntawm cov hlau molten yuav tsum tau soj ntsuam los ntawm cov spectrometer nyeem ncaj qha kom ntseeg tau tias cov hlau molten ua tau raws li qhov yuav tsum tau ua casting.

2. Kev Sib Tsoo Centrifugal
Kev Siv Dej Txias Hlau Pwm Centrifuge Casting: Siv lub tshuab centrifuge hlau pwm txias dej rau kev casting. Cov hlau molten kub siab raug nchuav tas li rau hauv cov pwm yeeb nkab tig ceev ceev. Nyob rau hauv qhov kev ua ntawm lub zog centrifugal, cov hlau molten tau faib sib npaug ntawm phab ntsa sab hauv ntawm cov pwm yeeb nkab, thiab cov hlau molten tau khov sai sai los ntawm kev txias dej los ua cov yeeb nkab hlau ductile. Tom qab casting tiav, cov yeeb nkab cam khwb cia raug tshuaj xyuas tam sim ntawd thiab hnyav rau qhov tsis zoo casting kom ntseeg tau tias qhov zoo ntawm txhua lub yeeb nkab.
Kev Kho Mob Kub: Cov neeg ua yeeb yamHlau Rajces muab tso rau hauv lub cub tawg kom annealing rau kev kho annealing kom tshem tawm cov kev ntxhov siab sab hauv uas tsim thaum lub sijhawm casting thiab txhim kho cov qauv metallographic thiab cov khoom siv kho tshuab ntawm cov yeeb nkab.
Kev Ntsuas Kev Ua HaujlwmTom qab annealing, cov yeeb nkab hlau ductile yuav raug rau ntau qhov kev xeem ua haujlwm nruj, suav nrog kev xeem indentation, kev xeem tsos, kev xeem flattening, kev xeem tensile, kev xeem hardness, kev xeem metallographic, thiab lwm yam. Cov yeeb nkab uas tsis ua raws li qhov yuav tsum tau ua yuav raug pov tseg thiab yuav tsis nkag mus rau hauv cov txheej txheem tom ntej.

3. Kev Ua Tiav
Tshuaj tsuag zincCov yeeb nkab hlau ductile raug kho nrog zinc los ntawm kev siv lub tshuab hluav taws xob high-voltage. Cov txheej zinc tuaj yeem tsim ib daim zaj duab xis tiv thaiv rau ntawm qhov chaw ntawm cov yeeb nkab kom txhim kho kev tiv thaiv xeb ntawm cov yeeb nkab.
Kev sib tsoo: Tsim NyogCov Yeeb Nkab Hlau Uas Muaj Cov Hlauraug xa mus rau qhov chaw sib tsoo thib peb kom kuaj xyuas qhov tsos, thiab lub qhov (socket), lub qhov dej (spigot) thiab phab ntsa sab hauv ntawm txhua lub yeeb nkab raug txhuam thiab ntxuav kom huv si kom ntseeg tau tias qhov chaw ntawm lub yeeb nkab tiaj tiaj thiab tiav thiab kev sib khi ntawm qhov sib txuas.
Kev Ntsuas HydrostaticCov kav dej kho tau raug kuaj hydrostatic, thiab qhov siab ntawm kev kuaj yog 10kg / cm² siab dua li tus qauv thoob ntiaj teb ISO2531 thiab tus qauv European, kom ntseeg tau tias cov kav dej tuaj yeem tiv taus qhov siab sab hauv txaus thiab ua tau raws li qhov yuav tsum tau ua ntawm kev siv tiag tiag.
Cov ntaub pua plag cementPhab ntsa sab hauv ntawm cov yeeb nkab yog centrifuge coated nrog cement los ntawm ob chav-chaw nres tsheb cement lining tshuab. Cov cement mortar siv tau dhau los ntawm kev tshuaj xyuas zoo thiab kev tswj hwm qhov sib piv. Tag nrho cov txheej txheem txheej txheem yog tswj los ntawm lub khoos phis tawj kom ntseeg tau tias qhov zoo sib xws thiab ruaj khov ntawm cov cement lining. Cov yeeb nkab uas muaj cement lining raug kho raws li qhov xav tau kom cov cement lining ruaj khov tag nrho.
Tshuaj tsuag asphaltCov kav dej uas kho lawm yuav raug cua sov rau saum npoo av ua ntej, thiab tom qab ntawd cov asphalt raug txau los ntawm lub tshuab txau ob chav. Cov txheej asphalt ntxiv ua rau cov kav dej tiv thaiv xeb ntau dua thiab ua rau cov kav dej siv tau ntev dua.
Kev Tshuaj Xyuas Zaum Kawg, Kev Ntim Khoom thiab Kev Khaws CiaCov kav dej uas txau nrog asphalt raug kuaj xyuas zaum kawg. Tsuas yog cov kav dej uas tsim nyog tag nrho thiaj li 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 rau kev siv.
