Daim ntawv dov txiasyog ib hom khoom tshiab uas raug nias txias thiab ua tiav los ntawmdaim ntawv kub dovVim tias nws tau dhau los ntawm ntau cov txheej txheem dov txias, nws qhov zoo ntawm qhov chaw zoo dua li cov ntawv dov kub. Tom qab kev kho cua sov, nws cov khoom siv kho tshuab kuj tau txhim kho zoo heev.
Raws li cov kev xav tau sib txawv ntawm txhua lub tuam txhab tsim khoom,phaj dov txiasFeem ntau muab faib ua ntau theem. Cov ntawv dov txias yog xa tuaj rau hauv cov kauj lossis cov ntawv tiaj tus, thiab nws cov tuab feem ntau yog qhia hauv millimeters. Hauv cov nqe lus ntawm qhov dav, lawv feem ntau muaj nyob rau hauv 1000 hli thiab 1250 hli qhov ntau thiab tsawg, thaum qhov ntev feem ntau yog 2000 hli thiab 2500 hli. Cov ntawv dov txias no tsis yog tsuas yog muaj cov khoom zoo heev thiab qhov zoo ntawm qhov chaw, tab sis kuj zoo heev hauv kev tiv thaiv corrosion, kev tiv thaiv qaug zog thiab kev zoo nkauj. Yog li ntawd, lawv tau siv dav hauv tsheb, kev tsim kho, khoom siv hauv tsev, khoom siv kev lag luam thiab lwm yam teb.
Cov qib ntawm cov ntawv txias txias
Cov qib uas siv ntau yog:
Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06 thiab lwm yam;
ST12: Qhia tias yog qib hlau feem ntau, nrog Q195,SPCC, DC01cov khoom siv qib yeej zoo ib yam;
ST13/14: Qhia rau tus lej hlau stamping, thiab 08AL, SPCD, DC03/04 qib khoom siv yeej zoo ib yam;
ST15/16: Qhia tias yog tus lej hlau stamping, thiab cov khoom siv qib 08AL, SPCE, SPCEN, DC05/06 yeej zoo ib yam.
Lub ntsiab lus ntawm cov khoom siv JIS Nyiv Pooj
SPCCT thiab SPCD sawv cev rau dab tsi?
SPCCT txhais tau tias cov hlau carbon txias dov thiab daim kab xev nrog lub zog tensile lav raws li tus qauv JIS Nyiv, thaum SPCD txhais tau tias cov hlau carbon txias dov thiab daim kab xev rau kev luam ntawv raws li tus qauv JIS Nyiv, thiab nws cov neeg suav yog 08AL (13237) cov hlau zoo carbon.
Ntxiv mus, hais txog cov lej tempering ntawm cov hlau carbon txias dov thiab strip, qhov xwm txheej annealed yog A, tus qauv tempering yog S, 1/8 hardness yog 8, 1/4 hardness yog 4, 1/2 hardness yog 2, thiab tag nrho hardness yog 1. Qhov tiav ntawm qhov chaw yog D rau qhov tiav tsis ci, thiab B rau qhov tiav ci, piv txwv li, SPCC-SD txhais tau tias cov hlau carbon txias dov rau kev siv dav dav nrog tus qauv tempering thiab qhov tiav tsis ci; SPCCT-SB txhais tau tias tus qauv tempered, ci tiav cov hlau carbon txias dov; thiab SPCCT-SB txhais tau tias tus qauv tempered, ci tiav cov hlau carbon txias dov rau kev siv dav dav nrog tus qauv tempering thiab qhov tiav tsis ci. Tus qauv tempering, ci ua tiav, cov hlau carbon txias dov yuav tsum tau ua kom ntseeg tau tias cov khoom siv kho tshuab; SPCC-1D yog qhia ua cov hlau carbon txias dov nyuaj, tsis ci tiav dov.
Qib hlau ua vaj tse yog raws li nram no: S + cov ntsiab lus carbon + tsab ntawv code (C, CK), uas cov ntsiab lus carbon nrog tus nqi nruab nrab * 100, tsab ntawv C txhais tau tias carbon, tsab ntawv K txhais tau tias hlau carburized.
Tuam Tshoj GB tus qauv khoom siv txhais tau tias
Feem ntau muab faib ua: Q195, Q215, Q235, Q255, Q275, thiab lwm yam. Q qhia tias qhov taw tes ntawm cov hlau "tawm los" thawj tsab ntawv ntawm lo lus hanyu pinyin, 195, 215, thiab lwm yam qhia tias qhov taw tes ntawm cov tshuaj lom neeg los ntawm cov ntsiab lus, qib hlau qis carbon: Q195, Q215, Q235, Q255, Q275 qib, qhov ntau dua cov pa roj carbon, qhov siab dua cov manganese cov ntsiab lus, qhov ruaj khov dua nws cov yas.
