DC nyob rau hauv DC01 txhais tau tias DIN 1623-1 (German txias-dov phaj txheem) tiaj tus hlau cov khoom me me steel txias-dov sawb thiab ntawv. DC yog DIN 1623-1 Cov khoom lag luam ntawm cov hlau; Txias dov sawb thiab daim ntawv me me unalloyed DC abbreviation nyob rau hauv steels.
Qhov sib sib zog nqus kev ua tau zoo theem sawv cev los ntawm 01, 02, 03 thiab 04 txawv. Tus naj npawb loj dua, qhov zoo ntawm tensile kev ua tau zoo.
Yog li ntawd,dc01 ua, DC02,dc03 ua, thiab DC04 sawv cev rau qib sib txawv ntawm cov hlau txias txias, thiab lawv cov duab sib sib zog nqus sib txawv.
01 cov khoom siv zoo tib yam, 02, 03 thiab 04 cov ntaub ntawv sib sib zog nqus nqus tau zoo dua kev kos duab sib sib zog nqus ntxiv lawv mus.
DC01 feem ntau tsis siv rau kev ncab, tsuas yog rau kev khoov yooj yim;
DC02 tuaj yeem siv rau kev kos duab ntiav, tab sis feem ntau tsuas yog siv rau kev khoov;
DC03 tuaj yeem hais tias yog lub rooj tsav xwm tensile;
DC04, qhov kawg yog qhov zoo tshaj plaws tensile zog thiab tuaj yeem siv rau kev kos duab sib sib zog nqus.
txheem kev sib raug zoo
German tus qauv DIN 1623 ST12 (DC01)
Cov txheej txheem European sib raug yog EN 10130 DC01

Cov qauv kev lag luam sib raug zoo ntawm Wuhan Iron thiab Steel Co., Ltd. yog Q/WG(LZ)20-2008 DC01
Cov txheej txheem kev lag luam Baosteel yog Q / BQB 403 DC01
Qhov sib txawv ntawm cov khoom siv kho tshuab ntawm DC 01-07 qib
Qhov txawv ntawm qhov kub dov thiab txias dov
1. Kub dov
Kub dov siv slabs (tsuas yog nruam nruam slabs) raws li raw cov ntaub ntawv, thiab yog rhuab los ua ib daim hlab los ntawm ntxhib dov units thiab tag dov units. Qhov kub steel sawb tawm ntawm qhov kawg dov zeb ntawm kev ua tiav dov yog txias rau qhov kub thiab txias los ntawm laminar ntws, thiab yog dov rau hauv steel strip coils los ntawm coiler. Cov cua txias steel strip coils tau ua haujlwm sib txawv raws li qhov sib txawv ntawm cov neeg siv khoom xav tau. Cov kab (smoothing, straightening, cross-cutting or slitting, inspection, weighting, packaging and marking, etc.) yog ua tiav rau hauv cov hlau phaj, tiaj tus coils thiab cov khoom siv steel strips.
Txhawm rau muab nws yooj yim, ib daim ntawm steel billet yog rhuab (nws yog liab-kub steel thaiv ntawm TV) thiab dov los ntawm ob peb hla, ces trimmed thiab ncaj rau hauv ib lub phaj steel. Qhov no yog hu ua kub dov.
2. Txias dov
Txias dov: kub-kuav los tiag steel coils yog siv los ua raw cov ntaub ntawv, thiab cov oxide nplai raug tshem tawm los ntawm pickling thiab ces txias dov tsis tu ncua. Cov khoom tiav yog ib qho nyuaj-dov coil. Vim qhov txias ua hauj lwm hardening tshwm sim los ntawm tas li txias deformation, lub zog, hardness, thiab toughness ntawm hard-dov coils nce. Cov yas Performance index yuav txo qis, yog li qhov kev ua haujlwm stamping yuav tsis zoo thiab nws tsuas yog siv tau rau qhov chaw uas yooj yim deformation.
Txhawm rau muab nws yooj yim, txias dov yog ua tiav thiab dov los ntawm lub hauv paus ntawm kub dov coils. Feem ntau hais lus, nws yog txheej txheem kub dov --pickling--txias dov.
Txias dov yog tsim los ntawm cov ntawv kub-kuav los tiag ntawm chav tsev kub. Txawm hais tias dov kuj tseem yuav ua kom sov lub phaj hlau thaum lub sijhawm ua haujlwm, nws tseem hu ua txias dov. Txij li thaum kub dov undergoes tas mus li txias deformation, txias dov muaj tsis zoo txhua yam khoom thiab siab heev hardness.
