Cov ntawv txias txiasyog ib yam tshiab ntawm cov khoom uas yog ntxiv txias nias thiab ua tiav los ntawmkub dov ntawv. Vim tias nws tau dhau los ua ntau yam txheej txheem txias dov, nws qhov chaw zoo yog qhov zoo dua li cov ntawv kub dov. Tom qab kev kho cua sov, nws cov khoom siv kho tshuab kuj tau ua kom zoo dua qub.
Raws li cov kev cai sib txawv ntawm txhua lub tuam txhab tsim khoom,txias dov phajfeem ntau muab faib ua ob peb theem. Cov ntawv txias dov yog xa hauv cov ntawv coils lossis cov ntawv tiaj tus, thiab nws cov tuab feem ntau qhia hauv millimeters. Hais txog qhov dav, lawv feem ntau muaj nyob rau hauv 1000 hli thiab 1250 hli qhov ntau thiab tsawg, thaum qhov ntev yog feem ntau 2000 hli thiab 2500 hli. Cov ntawv txias txias no tsis yog tsuas yog muaj cov khoom zoo heev thiab cov khoom zoo, tab sis kuj zoo heev hauv kev tiv thaiv corrosion, qaug zog thiab zoo nkauj. Yog li ntawd, lawv tau siv dav hauv tsheb, kev tsim kho, khoom siv hauv tsev, khoom siv thiab lwm yam haujlwm.
Qib ntawm cov ntawv txias dov
Cov qib uas nquag siv yog:
Q195, Q215, Q235, 08AL, SPCC, SPCD, SPCE, SPCEN, ST12, ST13, ST14, ST15, ST16, DC01, DC03, DC04, DC05, DC06 thiab lwm yam;
ST12: Qhia raws li qib steel feem ntau, nrog Q195,SPCC, dc01 uacov ntaub ntawv qib yog qhov pib zoo ib yam;
ST13/14: Qhia rau stamping qib steel tooj, thiab 08AL, SPCD, DC03/04 cov khoom siv qib yog tib yam;
ST15/16: Qhia raws li qib qib steel tooj, thiab 08AL, SPCE, SPCEN, DC05/06 cov khoom siv qib yog tib yam.
Nyiv JIS cov khoom siv lub ntsiab lus
SPCCT thiab SPCD sawv rau dab tsi?
SPCCT txhais tau hais tias txias dov carbon steel ntawv thiab sawb nrog lav lub zog tensile raws li Japanese JIS tus qauv, thaum SPCD txhais tau hais tias txias dov carbon steel ntawv thiab sawb rau stamping raws li Japanese JIS tus qauv, thiab nws cov Suav counterpart yog 08AL (13237) zoo carbon structural hlau.
Tsis tas li ntawd, hais txog lub tempering code ntawm txias dov carbon steel ntawv thiab sawb, lub annealed mob yog A, txheem tempering yog S, 1/8 hardness yog 8, 1/4 hardness yog 4, 1/2 hardness yog 2, thiab tag nrho. hardness yog 1. Nto tiav code yog D rau tsis-glossy tag, thiab B rau ci tiav, piv txwv li, SPCC-SD denotes txias dov carbon steel ntawv rau kev siv nrog standard tempering thiab tsis-glossy tag; SPCCT-SB qhia tus qauv tempered, ci tiav txias dov carbon steel ntawv; thiab SPCCT-SB qhia txog tus qauv tempered, ci tiav txias dov carbon steel ntawv rau kev siv nrog tus qauv tempering thiab tsis-glossy tiav. Standard tempering, ci ua, txias dov carbon ntawv yuav tsum tau los xyuas kom meej cov neeg kho tshuab zog; SPCC-1D tau qhia tias nyuaj, tsis yog-gloss tiav dov txias dov carbon steel ntawv.
Mechanical structural steel qib tau qhia raws li hauv qab no: S + carbon ntsiab lus + 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 carburized steel.
Tuam Tshoj GB txheem khoom lub ntsiab lus
Hauv paus muab faib ua: Q195, Q215, Q235, Q255, Q275, thiab lwm yam. Q qhia tias cov ntsiab lus ntawm cov hlau "yield" thawj tsab ntawv ntawm lo lus hanyu pinyin, 195, 215, thiab lwm yam. qhia tias qhov taw tes tawm ntawm tus nqi. ntawm cov tshuaj muaj pes tsawg leeg los ntawm cov ntsiab lus, qis carbon steel qib: Q195, Q215, Q235, Q255, Q275 qib, ntau dua cov ntsiab lus carbon, ntau dua cov ntsiab lus manganese, qhov ruaj khov nws cov yas.
