Kev piav qhia ntawm SPCC txias dov steel qib

1 npe
SPCCyog Ameslikas tus qauv Japanese (JIS) "kev siv dav davtxias dov carbon steel ntawvthiab strip" steel lub npe, tam sim no ntau lub teb chaws los yog cov lag luam ncaj qha siv los qhia lawv tus kheej tsim cov hlau zoo sib xws. Nco ntsoov: cov qib zoo sib xws yog SPCD (cov ntawv txias-dov carbon steel thiab sawb rau stamping), SPCE (cov ntawv txias-dov carbon steel thiab strip rau kev sib sib zog nqus kos duab), SPCCK\SPCCCE, thiab lwm yam. (tshwj xeeb steel rau TV teeb), SPCC4D\SPCC8D, thiab lwm yam.

2 Cheebtsam
Japanese steel (JIS series) nyob rau hauv qib ntawm cov qauv zoo tib yam steel feem ntau muaj peb feem ntawm thawj feem ntawm cov khoom, xws li: S (Steel) uas steel, F (Ferrum) uas cov hlau; qhov thib ob ntawm cov duab sib txawv, hom, thiab siv, xws li P (Plate) tias lub phaj, T (Tube) uas lub raj, K (Kogu) uas cov cuab yeej; qhov thib peb ntawm cov yam ntxwv ntawm tus lej, feem ntau yog qhov tsawg kawg nkaus tensile lub zog. Feem ntau qhov tsawg kawg nkaus tensile zog. Xws li: SS400 - thawj S hais tias steel (Steel), qhov thib ob S hais tias "cov qauv" (Structure), 400 rau qhov qis qis ntawm tensile zog ntawm 400MPa, tag nrho tensile zog ntawm 400MPa rau cov qauv steel nrog tensile. Lub zog ntawm 400MPa.

Ntxiv: SPCC - txias dov carbon steel ntawv thiab sawb rau kev siv, sib npaug rau Tuam Tshoj Q195-215A qib. Qhov thib peb tsab ntawv C yog lub npe luv rau txias txias. Yuav tsum tau xyuas kom meej tias qhov kev xeem tensile, thaum kawg ntawm qib ntxiv T rau SPCT.

3 steel kev faib tawm
Nyiv covtxias dov carbon steel phajCov qib siv tau: SPCC, SPCD, SPCE cov cim: S - steel (Steel), P - phaj (Plate), C - txias dov (txias), plaub C - ntau (ntau), D - qib stamping (Draw), E - Kev kos duab sib sib zog nqus (Elongation)

Kev kho cua sov txheej txheem: A-Annealed, S-Annealed + Flat, 8-(1/8) nyuaj, 4-(1/4) nyuaj, 2-(1/2) nyuaj, 1-nyuaj.

Kev kos duab theem: ZF- rau xuas nrig ntaus qhov chaw nrog cov duab nyuaj tshaj plaws, HF- rau xuas nrig ntaus nrog cov duab nyuaj heev, F- rau xuas nrig ntaus nrog cov duab nyuaj.

Deg Finishing Status: D - Dull (rolls ua tiav los ntawm kev sib tsoo tshuab thiab tom qab ntawd tua peened), B - Bright Surface (rolls processed by sib tsoo tshuab).

Deg zoo: FC-advanced finishing nto, FB-ntau dua finishing nto. Qhov xwm txheej, qhov chaw ua tiav, qhov zoo ntawm qhov tsim, qib kos duab (rau SPCE nkaus xwb), cov khoom tshwj xeeb thiab qhov loj, qhov tseeb profile (thickness thiab / lossis dav, ntev, tsis sib xws).
