Tanthauzo la dzina limodzi
SPCCPoyamba chinali muyezo wa ku Japan (JIS) "wogwiritsidwa ntchito kwambiri"pepala lozizira lozungulira la kabonindi dzina lachitsulo la strip", mayiko ambiri kapena mabizinesi omwe tsopano amagwiritsidwa ntchito mwachindunji kusonyeza kupanga kwawo chitsulo chofanana. Dziwani: magiredi ofanana ndi awa: SPCD (pepala lachitsulo la carbon lozunguliridwa ndi cold-rolled ndi strip for stamping), SPCE (pepala lachitsulo la carbon lozunguliridwa ndi cold-rolled ndi strip for deep drawing), SPCCK\SPCCCE, ndi zina zotero. (chitsulo chapadera cha ma TV), SPCC4D\SPCC8D, ndi zina zotero. (chitsulo cholimba, chomwe chimagwiritsidwa ntchito pa nthiti za njinga, ndi zina zotero), motsatana, pazochitika zosiyanasiyana.
Zigawo ziwiri
Chitsulo cha ku Japan (JIS series) chomwe chili mu kalasi ya chitsulo chokhazikika chimakhala ndi magawo atatu a gawo loyamba la zinthuzo, monga: S (Steel) kuti chitsulo, F (Ferrum) kuti chitsulo; gawo lachiwiri la mawonekedwe osiyanasiyana, mitundu, ndi ntchito, monga P (Plate) kuti mbale, T (Chubu) kuti chubu, K (Kogu) kuti chida; gawo lachitatu la makhalidwe a nambala, nthawi zambiri mphamvu yocheperako yolimba. Nthawi zambiri mphamvu yocheperako yolimba. Monga: SS400 - yoyamba S anati chitsulo (Steel), yachiwiri S anati "structure" (Structure), 400 ya malire otsika a mphamvu yolimba ya 400MPa, mphamvu yonse yolimba ya 400MPa ya chitsulo chokhazikika chokhala ndi mphamvu yolimba ya 400MPa.
Zowonjezera: SPCC - pepala lachitsulo la carbon lozunguliridwa ndi chipolopolo chozizira komanso mzere wogwiritsidwa ntchito wamba, wofanana ndi giredi ya China Q195-215A. Chilembo chachitatu C ndi chidule cha giredi ya kuzizira kozizira. Muyenera kuonetsetsa kuti mayeso omangika, kumapeto kwa giredi kuphatikiza T ya SPCCT.
Gulu la chitsulo la 3
Za ku Japanmbale yozizira yozungulira mpweya wachitsulomagiredi oyenerera: SPCC, SPCD, zizindikiro za SPCE: S - chitsulo (Chitsulo), P - mbale (Mbale), C - chozungulira chozizira (chozizira), C chachinayi - chofala (chofala), D - kalasi yopondaponda (Chojambula), E - kalasi yozama yojambula (Kutalika)
Momwe kutentha kumakhalira: A-Annealed, S-Annealed + Flat, 8-(1/8) yolimba, 4-(1/4) yolimba, 2-(1/2) yolimba, 1-yolimba.
Mulingo wa magwiridwe antchito ojambula: ZF- ya zida zoboola ndi zojambula zovuta kwambiri, HF- ya zida zoboola ndi zojambula zovuta kwambiri, F- ya zida zoboola ndi zojambula zovuta.
Mkhalidwe Womaliza Pamwamba: D - Wosawoneka bwino (mipukutu yokonzedwa ndi makina opukutira kenako n’kuchotsedwa), B - Wowala Pamwamba (mipukutu yokonzedwa ndi makina opukutira).
Ubwino wa pamwamba: Malo omalizira apamwamba a FC, malo omalizira apamwamba a FB. Mkhalidwe, momwe malo omalizira alili, mawonekedwe a pamwamba, mtundu wa zojambula (za SPCE zokha), kufotokozera kwa chinthu ndi kukula kwake, kulondola kwa mbiri yake (kukhuthala ndi/kapena m'lifupi, kutalika, kusalingana).
Nthawi yotumizira: Juni-21-2024
