Cov kav dej ductile muaj cov yam ntxwv ntawm lawv qhov zoo heev toughness, siab zog, corrosion kuj, tsis ua hauj lwm tus nqi, thiab lub neej ntev kev pab cuam. Thaum yuav cov kav hlau kav hlau, peb tuaj yeem txiav txim siab lawv qhov zoo li cas? Cia peb saib hauv qab no.
01.Kev soj ntsuam xyuas
Tshawb xyuas cov yeeb nkab kom ntseeg tau tias cov txheej txheem sab nraud thiab sab hauv los tiv thaiv- kev kho corrosion yog zoo ib yam thiab tsis zoo, thiab tag nrho cov cim ntawm cov yeeb nkab lub cev tiav. Sab nrauv yuav tsum du thiab txawm, tsis muaj qhov tsis xws luag xws li tawg lossis tsis sib xws; lub qhov (socket) pob qij txha yuav tsum tsis muaj burrs, casting marks, los yog tev tawm los tiv thaiv -corrosion txheej; sab hauv ntawm cov yeeb nkab yuav tsum yog uniformly du, tsis muaj kab nrib pleb los yog pom tseeb tsis xws luag xws li tev los tiv thaiv -corrosion txheej.
02.Dimension Check
Ntsuas txoj kab uas hla ntawm lub qhov (socket) thiab spigot, cov yeeb nkab ntev, phab ntsa thickness, thiab lwm yam tsis muaj qhov ntev ntawm cov kav hlau kav los xyuas kom meej tias lawv ua tau raws li tus qauv specifications. Txij li cov kev qhia tshwj xeeb sib txawv rau cov qib sib txawv thiab qhov ntau thiab tsawg ntawm cov kav dej hlau, nws yog ib qho tseem ceeb kom paub meej tias cov yeeb nkab qib thiab qhov loj me ua ntej ua qhov kev tshuaj xyuas.
03.Kev soj ntsuam zoo
Thaum xa khoom tuaj, koj tuaj yeem thov cov qauv los ntawm cov chaw tsim khoom lossis coj cov qauv random ntawm -qhov chaw rau kev sim ntawm qhov thib peb - qhov chaw xeem.
Ntsuas cov qauv metallographic, lub zog tensile, thiab Brinell hardness ntawm cov kav hlau hlau los ntsuas seb cov khoom xws li spheroidization npaum li cas, toughness, hardness, thiab lub zog ua tau raws li qhov yuav tsum tau ua.
Tom qab txhim kho ib ntu ntawm cov yeeb nkab ntawm - qhov chaw, lub raj xa dej tau raug nias los xyuas nws qhov kev ua haujlwm siab thiab kev sib khi.
04. Chaw tsim khoom lub koob npe nrov
Xaiv cov chaw tsim khoom nrog cov ntawv pov thawj tiav, muaj peev xwm tsim tau zoo, thiab lub koob npe nrov kom ntseeg tau cov khoom zoo dua qub thiab txhim khu kev qha rau yav tom ntej.
Raws li cov txheej txheem saum toj no, koj tuaj yeem ntsuas qhov zoo ntawm cov kav hlau kav hlau. Thaum yuav cov kav hlau kav hlau, nws raug nquahu kom koj xaiv cov chaw tsim khoom muaj npe nrov thiab thov cov ntaub ntawv pov thawj cuam tshuam.
