Cim Ford, tus thawj tswj hwm kev txhim kho ntawm AFG kev lag luam, Inc., piav qhia:
Tempered iav yog hais txog plaub zaug muaj zog dua "dog dig," lossis analealed, iav. Thiab tsis zoo li annealed iav, uas tuaj yeem tawg mus rau hauv jagged shards thaum tawg, tempered iav pob txha lov rau hauv tej daim me me, muaj kev phom sij. Raws li qhov tshwm sim, tempered iav yog siv nyob rau hauv cov chaw ib puag ncig uas tib neeg kev nyab xeeb yog qhov teeb meem. Cov ntawv thov suav nrog cov qhov rai sab thiab lub qhov rooj nkag, da dej, cov rooj tog zaum patio, microwave ncu thiab skylights.
Los npaj iav rau cov txheej txheem tempering, nws yuav tsum xub txiav rau qhov loj me. (Lub zog txo lossis cov khoom tsis ua haujlwm yuav tshwm sim yog tias muaj kev kho cov ntaub ntawv, xws li kev kho cua sov. Ib qho abrasivesuch li sandpaperak nplaum ceev tawm ntawm iav, uas yog tom qab ntxuav.
Daim phaib qhauj tawm
Tom ntej no, lub iav pib lub tshav kub kho cua sov nyob rau hauv uas nws mus ncig los ntawm qhov cub sov, yog nyob rau hauv ib tug batch los yog kev pub khoom lag luam. Qhov cub cua sov lub khob kom sov rau ntau dua 600 degrees Celsius. (Cov qauv kev lag luam yog 620 degrees Celsius.) Lub iav ces undergoes tus txheej txheem siab txias hu ua "quenching." Nyob rau lub sijhawm no, uas kav ib qho kawg nkaus xwb, cov cua kub siab tawg rau saum npoo ntawm lub khob los ntawm cov khoom siv ntawm nozzles hauv cov haujlwm sib txawv. Quenching txias cov npoo sab nraud ntawm cov iav ntau ntau tshaj qhov chaw nruab nrab. Raws li qhov nruab nrab ntawm lub khob txias, nws sim rub rov qab los ntawm cov chaw sab nraud. Raws li qhov tshwm sim, qhov chaw seem nyob rau hauv nro, thiab cov npoo sab nraud mus rau hauv cov chaw ua ke, uas muab cov cua sov.
Iav hauv qhov nro tawg txog tsib zaug yooj yim dua li nws ua hauv compression. Annealed iav yuav tawg ntawm 6,000 phaus ib square nti (PSI). Lub iav tempered, raws li Tsoom Fwv Cov Lus Qhia Tshwj Xeeb, yuav tsum muaj lub compression ntawm 10,000 psi lossis ntau dua; Nws feem ntau tawg ntawm kwv yees li 24,000 PSI.
Lwm txoj hauv kev ua kom tempered iav yog tshuaj lom neeg ua kom sov, nyob rau hauv uas ntau yam tshuaj txauv ions nyob rau saum npoo ntawm lub khob kom thiaj tsim tau compression. Tab sis vim tias cov qauv no raug nqi ntau dua li siv ntsuas kub thiab tso tawm, nws tsis siv dav.
Duab: AFG Kev Lag Luam
Ntsuas Cov Iavkoom nrog punching nws kom paub tseeb tias lub iav lov rau hauv ntau me me, zoo sib xws me me. Ib qho tuaj yeem paub tseeb tias cov iav tau ua kom tau yooj yim los ntawm cov qauv hauv cov iav tawg.
Kev lag luam
Tus Kws Ntsuam Xyuas Cov IavKev tshuaj xyuas ib daim ntawv ntawm lub khob tempered, nrhiav cov npuas, pob zeb, khawb lossis lwm qhov flaws uas tuaj yeem ua rau nws tsis muaj zog.
