Tsananguro yeSPCC cold rolled steel grades

Tsanangudzo yezita rimwe chete
SPCCPakutanga yaive "standard yeJapan (JIS)" yakashandiswa zvakanyanya.pepa resimbi yekabhoni yakakungurutswa inotonhorauye zita resimbi re "strip", ikozvino nyika dzakawanda kana mabhizinesi anoshandiswa zvakananga kuratidza kugadzirwa kwavo kwesimbi yakafanana. Cherechedza: mamakisi akafanana ndeaya SPCD (cold-rolled carbon steel sheet uye strip ye stamping), SPCE (cold-rolled carbon steel sheet uye strip ye deep drawing), SPCCK\SPCCCE, nezvimwewo (special steel for TV sets), SPCC4D\SPCC8D, nezvimwewo (hard steel, inoshandiswa pamarimu emabhasikoro, nezvimwewo), zvichiteerana, pazviitiko zvakasiyana.

Zvikamu zviviri
Simbi yekuJapan (JIS series) iri muchikamu chesimbi yakajairika inoumbwa nezvikamu zvitatu zvechikamu chekutanga chezvinhu, zvakaita se: S (Steel) kuti simbi, F (Ferrum) kuti simbi; chikamu chechipiri chezvimiro zvakasiyana, mhando, uye mashandisirwo, zvakaita seP (Plate) kuti plate, T (Tube) kuti chubhu, K (Kogu) kuti chishandiso; chikamu chechitatu chehunhu hwenhamba, kazhinji simba rekudhonza. Kazhinji simba rekudhonza. Zvakadai se: SS400 - yekutanga S yakati simbi (Steel), yechipiri S yakati "chimiro" (Structure), 400 yemuganho wakaderera wekudhonza we400MPa, simba rekudhonza re400MPa yesimbi yakajairika ine simba rekudhonza re400MPa.

Zvekuwedzera: SPCC - jira resimbi rakaputirwa nekabhoni rakaputirwa uye strip yekushandiswa kwakajairika, yakaenzana negiredhi reChina Q195-215A. Bhii rechitatu C idimbu rekuti Cold inotonhora. Zvinodiwa kuve nechokwadi chekuti bvunzo yekudhonza, iri pakupera kwegiredhi pamwe chete naT yeSPCCT.

3 kupatsanura simbi
yeJapanndiro yesimbi yekabhoni inotonhoramamakisi anoshanda: SPCC, SPCD, zviratidzo zveSPCE: S - simbi (Simbi), P - ndiro (Ndiro), C - inotonhorera yakakungurutswa (inotonhora), C yechina - yakajairika (yakajairika), D - giredhi rekusimbisa (Dhonza), E - giredhi rekudhirowa rakadzika (Kureba)

Mamiriro ekurapa kupisa: A-Annealed, S-Annealed + Flat, 8-(1/8) yakaoma, 4-(1/4) yakaoma, 2-(1/2) yakaoma, 1-yakaoma.

Danho rekushanda kwedhirowa: ZF- yekubatanidza zvikamu zvine dhizaini yakaoma kunzwisisa, HF- yekubatanidza zvikamu zvine dhizaini yakaoma kunzwisisa, F- yekubatanidza zvikamu zvine dhizaini yakaoma kunzwisisa.

Mamiriro Ekupedzisa Pamusoro: D - Kusviba (mipumburu inogadziriswa nemuchina wekukuya wozobva wapfurwa), B - Kupenya Pamusoro (mipumburu inogadziriswa nemuchina wekukuya).

Hunhu hwepamusoro: Nzvimbo yekupedzisa yepamusoro yeFC, nzvimbo yekupedzisa yepamusoro yeFB. Mamiriro, mamiriro ekupedzisa pamusoro, chimiro chehunhu hwepamusoro, giredhi rekudhirowa (reSPCE chete), tsanangudzo yezvigadzirwa nehukuru, kururama kweprofile (ukobvu uye/kana upamhi, kureba, kusaenzana).
