Cold Colded Ntawvyog cov khoom tshiab ntawm cov khoom lag luam uas yog cov khoom txias ntxiv thiab ua tiav los ntawmKub Cov Ntawv RolledCov. Vim tias nws tau dhau los muaj ntau cov txheej txheem txias heev, nws cov npoo zoo yog qhov zoo dua li cov ntawv kub kub. Tom qab kev kho cua sov, nws cov khoom siv neeg kho tshuab kuj tau ua kom zoo dua qub.
Raws li cov cai yuav tsum tau sib txawv ntawm txhua qhov kev lag luam ntau lawm,Txias Rolled Phajfeem ntau muab faib ua ntau theem. Txias cov ntawv tawm yog xa hauv coils lossis daim ntawv tiaj tus, thiab nws cov tuab tuab yog qhia hauv millimeters. Hais txog qhov dav, lawv feem ntau muaj nyob rau hauv 1000 mm thiab 1250 hli ntau thiab tsawg, thaum lub sijhawm ntev feem ntau yog 2000 mm thiab 2500 hli. Cov nplooj ntawv txias no tsis tsuas yog muaj cov cuab yeej zoo thiab zoo nyob rau hauv corrosion tsis kam, nkees tsis kam thiab loog. Raws li qhov tshwm sim, lawv tau siv dav hauv kev siv tsheb, kev tsim kho, cov khoom siv hauv tsev, khoom siv thiab lwm daim teb.
Cov Qib Ntawm Cov Khaub Ncaws Txias Txias
Cov qhab nia siv feem ntau yog:
Q195, Q215, Q235, 08al, SPCD, SPCD, SPCD, SPCEN, SPCEN, STCEN, ST16, DC01, DC04, DC06 thiab lwm yam;
St12: Qhia raws li cov qauv steel feem ntau, nrog Q195,Tus kab mob spc, Dc01Cov khoom siv tau kawm yog ib qho zoo ib yam;
St13 / 14: qhia rau cov lej qhabnias tus lej steel, thiab 08A, SPCD, DCD, DC03 / 04 cov khoom siv yog yeej zoo ib yam;
ST15 / 16: qhia raws li Stamping Back Steel tooj, thiab 08A, SPCE, SPCEN, DCENS, DC05 / 06 cov khoom siv yog tib yam.
Nyiv JIS Cov Khoom Siv Txhais Lus
SpCCT thiab SPCD sawv ntsug?
SPCCT txhais tau tias txias cov ntawv ntim cov hlau thiab cov txaij nrog cov qauv Japoons, thiab nws cov qauv xov xwm Hlau.
Tsis tas li ntawd, hais txog qhov kev sim siab ntawm cov khaub ncaws txias carbon steel thiab sawb yog s, 1, 1/2 hardness yog 4, 1/2 hardness yog 2, thiab puv Hardness yog 1. Nto tiav code yog D rau cov ntawv uas tsis ua tiav, piv txwv li, SPCC-SNTOn Spcct-SB txhais tau cov txheej txheem tempered, ci tiav txias rolled carbon steel ntawv; Thiab SPCCT-SB txhais tau qhov tempered, ci tiav txias carbon steel ntawv rau kev siv kev kub thiab ua kom tiav. Txheem tempering, kev ua yeeb yam zoo, cov ntaub pua plag txias rau cov khoom siv tau kom muaj cov khoom siv mechanical. Spcc-1D tau tshaj tawm tias nyuaj, tsis yog-pob zuag yaj kuav cov ntawv txias carbon steel ntawv.
Cov txheej txheem hlau qib hlau tau nthuav tawm raws li hauv qab no: S + Cov Lus Qhia Cov Khoom Siv rau cov pa roj carbon monanple +)
Tuam Tshoj GB Txheem Khoom Ntsiab
Yeej muab faib ua: Q195, Q215, Q235, Q225, Q255, thiab lwm yam "Thawj Tsab Ntawv Hanyu Pinyin, 195, thiab lwm yam. Qhia tias cov txiaj ntsig ntawm tus nqi ntawm cov tshuaj lom neeg muaj pes tsawg leeg los ntawm cov ntsiab lus, Qis Carbon Steel qib: Q195, Q215, Q235, Q255, Q275 qib, qhov ntau dua cov ntsiab lus carbon, ntau dua cov ntsiab lus manganese, qhov ntau ruaj khov nws cov plasterity.
