Mark Ford, tus thawj coj kev tsim khoom ntawm AFG Industries, Inc., piav qhia tias:
Cov iav tempered muaj zog li plaub npaug ntawm cov iav "ib txwm," lossis iav annealed. Thiab tsis zoo li cov iav annealed, uas tuaj yeem tawg ua tej daim me me thaum tawg, cov iav tempered tawg ua tej daim me me, tsis muaj teeb meem. Yog li ntawd, cov iav tempered siv rau hauv cov chaw uas muaj teeb meem kev nyab xeeb ntawm tib neeg. Cov ntawv thov suav nrog cov qhov rai sab thiab tom qab hauv tsheb, qhov rooj nkag, chav da dej thiab lub dab da dej, chaw ua si racquetball, rooj tog zaum patio, qhov cub microwave thiab lub qhov rais saum ru tsev.
Yuav kom npaj tau iav rau txoj kev tempering, yuav tsum txiav ua ntej kom loj li koj xav tau. (Kev txo zog lossis kev ua tsis tiav ntawm cov khoom tuaj yeem tshwm sim yog tias muaj kev ua haujlwm tsim khoom, xws li etching lossis edging, tshwm sim tom qab kev kho cua sov.) Tom qab ntawd, daim iav raug kuaj xyuas seb puas muaj qhov tsis zoo uas yuav ua rau tawg ntawm txhua kauj ruam thaum lub sijhawm tempering. Cov khoom siv abrasive xws li ntawv xuab zeb tshem cov npoo ntse ntawm daim iav, uas tom qab ntawd ntxuav.
TSHAJ TAWM
Tom qab ntawd, lub iav pib ua cov txheej txheem kho cua sov uas nws mus los ntawm lub qhov cub tempering, txawm tias nyob rau hauv ib pawg lossis pub tas mus li. Lub qhov cub ua kom lub iav kub txog li ntau dua 600 degrees Celsius. (Tus qauv kev lag luam yog 620 degrees Celsius.) Lub iav tom qab ntawd dhau los ntawm cov txheej txheem txias siab hu ua "quenching." Thaum lub sijhawm no, uas kav ntev li ob peb feeb xwb, cua siab tshuab lub ntsej muag ntawm lub iav los ntawm ntau lub nozzles hauv ntau qhov chaw. Quenching ua rau cov nplaim sab nraud ntawm lub iav txias sai dua li qhov chaw nruab nrab. Thaum qhov chaw nruab nrab ntawm lub iav txias, nws sim rub rov qab los ntawm cov nplaim sab nraud. Yog li ntawd, qhov chaw nruab nrab tseem nyob hauv qhov nruj, thiab cov nplaim sab nraud mus rau hauv kev sib zog, uas ua rau lub iav tempered nws lub zog.
Cov iav uas raug nias yuav tawg yooj yim dua li tsib npaug ntawm qhov raug nias. Cov iav uas raug nias kom kub yuav tawg ntawm 6,000 phaus ib nti (psi). Cov iav uas raug nias kom kub, raws li cov lus qhia ntawm tsoomfwv tebchaws, yuav tsum muaj qhov nias ntawm qhov chaw ntawm 10,000 psi lossis ntau dua; feem ntau nws tawg ntawm kwv yees li 24,000 psi.
Lwm txoj hauv kev los ua cov iav tempered yog kev siv tshuaj tempering, uas ntau yam tshuaj sib pauv cov ions ntawm qhov chaw ntawm lub iav kom tsim kev sib zog. Tab sis vim tias txoj kev no kim dua li siv cov qhov cub tempering thiab quenching, nws tsis siv dav.

SIM LUB IAVYuav tsum tau xuas nrig kom paub tseeb tias lub iav tawg ua ntau daim me me, zoo ib yam. Ib tug neeg tuaj yeem paub tseeb tias lub iav puas tau raug kho kom zoo raws li tus qauv ntawm cov iav tawg.
LAG LUAM
TUS NEEG TSHEB IAVtshuaj xyuas ib daim iav tempered, nrhiav cov npuas dej, pob zeb, khawb lossis lwm yam qhov tsis zoo uas yuav ua rau nws tsis muaj zog.
