Tsananguro yeSPCC inotonhora yakakungurutswa simbi mamakisi

1 tsananguro yezita
SPCCpakutanga yaive chiyero cheJapan (JIS) "kushandiswa kwese kweinotonhora yakakungurutswa kabhoni simbi sheetuye strip" zita resimbi, ikozvino nyika zhinji kana mabhizinesi anoshandiswa zvakananga kuratidza kugadzirwa kwavo kwesimbi yakafanana. Cherechedza: mamakisi akafanana ndee SPCD (inotonhora-yakakungurutswa kabhoni simbi pepa uye tambo yekutsikisa), SPCE (inotonhora-yakakungurutswa kabhoni simbi pepa uye strip yekudhirowa kwakadzika), SPCCK\SPCCCE, etc. (special steel for TV sets), SPCC4D\SPCC8D simbi yakaoma, etc. zviitiko.

2 Zvikamu
Japanese simbi (JIS dzakatevedzana) ari mugiredhi zvakajairika structural simbi kunyanya rine zvikamu zvitatu chikamu chokutanga zvinhu, akadai: S (Steel) kuti simbi, F (Ferrum) kuti simbi; chikamu chechipiri chezvimiro zvakasiyana, marudzi, uye kushandiswa, zvakadai seP (Plate) iyo ndiro, T (Tube) iyo chubhu, K (Kogu) iyo chombo; chikamu chetatu chehunhu hwenhamba, kazhinji kacho simba rekushomeka. Kazhinji kacho simba rekuita zvishoma. Zvakadai se: SS400 - yekutanga S yakati simbi (Simbi), wechipiri S akati "chimiro" (Structure), 400 nokuda kwemuganhu wakaderera we 400MPa simba, iyo yose tensile simba re 400MPa kune mukuru Structural simbi ine simba rekugadzirisa 400MPa.

Supplementary: SPCC - inotonhora yakakungurutswa kabhoni simbi pepa uye tambo yekushandiswa kwese, yakaenzana neChina Q195-215A giredhi. Vara rechitatu C ichidimbu cheKutonhora. Inoda kuve nechokwadi chekuti bvunzo dzekusimba, mukupera kwegiredhi pamwe neT yeSPCCT.

3 simbi kupatsanura
yeJapaninotonhora yakakungurutswa kabhoni simbi ndiromagiredhi anoshanda: SPCC, SPCD, SPCE zviratidzo: S - simbi (Simbi), P - ndiro (Plate), C - inotonhora yakakungurutswa (inotonhora), yechina C - yakajairika (yakajairika), D - stamping giredhi (Dhiza), E - yakadzika yekudhirowa giredhi (Elongation)

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

Kudhirowa danho rekuita: ZF- yekubaya zvikamu zvine kudhirowa kwakanyanya, HF- yekubaya zvikamu zvine kudhirowa kwakanyanya, F- yekubaya zvikamu zvine kudhirowa kwakaoma.

Surface Finishing Status: D - Dull (mipumburu yakagadziridzwa nemuchina wekukuya uye wobva wapfurwa peened), B - Bright Surface (mipumburu yakagadziriswa nemuchina wekukuya).

Unhu hwepamusoro: FC-yepamusoro yekupedzisa nzvimbo, FB-yepamusoro yekupedzisa nzvimbo. Mamiriro ezvinhu, mamiriro ekupedzisa kwepamusoro, dhizaini yemhando yepamusoro, giredhi rekudhirowa (yeSPCE chete), kutsanangurwa kwechigadzirwa uye saizi, kurongeka kweprofile (ukobvu uye / kana hupamhi, kureba, kusaenzana).
