Q: Cov cuab yeej tshwj xeeb twg yog 'Si' (Silicon) nyob rau hauv ib lub caij nplooj ntoos hlav zoo li 60Si2Mn muab?
A:Silicon (Si) yog ib qho tseem ceeb alloying khoom nyob rau hauv caij nplooj ntoos hlav steels. Nws ua rau kom cov hlau tsis muaj zog thiab tsis kam mus tas li deformation (nws "yield zog"). Nws kuj tseem txhim kho lub hardenability ntawm cov hlau, tso cai rau nws ua tiav lub zog siab zoo thoob plaws hauv nws cov ntoo khaub lig- ntu thaum kho cua sov. Tsis tas li ntawd, nws txhim kho cov khoom siv tiv thaiv oxidation thiab decarburization thaum kub - txheej txheem tsim, khaws cia zoo.
Q: Dab tsi yog 'decarburization' thiab vim li cas nws thiaj li cuam tshuam rau txoj kev tsheb ciav hlau?
A:Decarburization yog ib qho kev kho cua sov uas cov ntsiab lus ntawm cov hlau raug txo vim yog cov tshuaj tiv thaiv nrog oxygen hauv cov cua. Txij li cov pa roj carbon yog ib qho tseem ceeb rau hardness thiab lub zog, qhov no tsim ib tug mos nto txheej ntawm clip. Cov txheej mos no yog qhov ua rau qaug zog tawg nyob rau hauv cyclic dabtsi yog khoov kev ntxhov siab thiab tuaj yeem ua rau tsis ua tiav ntxov. Cov cua sov cua sov tau siv thaum lub sijhawm kho cua sov los tiv thaiv qhov no.
Q: Yuav ua li cas yog qhov 'hardness profile' ntawm clip' cross-section?
A:Txhawm rau txheeb xyuas qhov ua tau zoo sib xws thiab tsis muaj decarburization, tus qauv clip raug txiav hla -sectionally thiab meticulously polished. Kev ntsuas hardness (piv txwv li, Vickers lossis Rockwell) yog tom qab ntawd raug coj los ntawm cov ntug mus rau qhov tseem ceeb ntawm cov khoom. Qhov no tsim ib daim duab hardness profile. Lub cua sov kom zoo-kho clip yuav qhia tau ib qho kev sib tw siab tawv thoob plaws, tsis muaj qhov poob tseem ceeb- tawm ntawm cov npoo, lees paub nws qhov zoo.
Q: Lub hom phiaj ntawm 'load-deflection nkhaus' yog dab tsi?
A:Lub load-deflection nkhaus yog ib qho qauv duab uas tau txais thaum kuaj. Nws plots lub zog yuav tsum tau deflect lub clip tiv thaiv tus nqi ntawm deflection. Qhov nkhaus no nthuav tawm cov khoom tseem ceeb: qhov pib nruj (qhov nqes ntawm txoj kab nqes), txoj kab ncaj nraim, qhov taw tes uas pib deformation mus tas li (yield point), thiab qhov siab tshaj plaws load peev xwm. Nws yog thawj tus ntiv tes ntawm qhov clip tus cwj pwm txhua yam thiab yog qhov tseem ceeb rau kev tsim qauv siv tau thiab kev tswj kom zoo.
Q: Vim li cas ib daim clip yuav raug "Magnetic particle soj ntsuam" (MPI)?
A:Magnetic Particle Inspection (MPI) yog ib qho uas tsis yog -kev ntsuas kev puas tsuaj uas siv los txheeb xyuas qhov chaw thiab nyob ze - qhov chaw ntawm qhov chaw, xws li cov kab nrib pleb zoo, seams, los yog kev sib txuas, uas tsis pom ntawm qhov muag liab qab. Cov clip yog magnetized, thiab hlau hais yog siv. Ib qho kev tsis txaus ntseeg tsim ib qho chaw xau uas nyiam cov khoom, ua rau pom pom. Nws yog cov kauj ruam tswj tau zoo, tshwj xeeb tshaj yog rau cov ntawv thov tseem ceeb, kom tsis txhob muaj cov clips tsis zoo nkag mus rau kev pabcuam.
