Kufotokozera kwa ozizira ozizira

1 Dzina Tanthauzo
Sphycanali woyamba ku Japan (Jis) "Kugwiritsa Ntchito KwambiriMapepala ozizira ozizirandi steel dzina lachitsulo, masiku ano kapena mabizinesi ambiri amagwiritsidwa ntchito mwachindunji kuti afotokozere zitsulo zofananira. Chidziwitso chofanana ndi spcd (sproted starm state stamping), sprid-carbon stofu yachitsulo ndipo Mvula yojambula kwambiri), spcck \ spcccy, etc. (spcc4d \ spcc4d \ spcc4d \ spcc8d, etc. (molimbika Zitsulo, zomwe zimagwiritsidwa ntchito pa njinga za njinga, etc.), motero, kwa nthawi zosiyanasiyana.

Magawo awiri
Chitsulo cha Japan (mndandanda wa yis) mu giredi wamba zitsulo makamaka pazigawo zitatu za gawo loyamba la zinthuzo, monga: s (steel) kuti chitsulo, chomwe chitsulo; Gawo lachiwiri la mawonekedwe osiyanasiyana, mitundu, ndikugwiritsa ntchito, monga p (plate) kuti mbaleyo, t (chubu) kuti chida; gawo lachitatu la manambala, nthawi zambiri mphamvu yocheperako. Nthawi zambiri mphamvu yocheperako. Monga: SS400 - Yoyamba ya SEEL (Steel), Kachiwiri Stie " mphamvu ya 49PA.

Zowonjezera: SPCC - Yozizira yozizira caboni chitsulo ndi mzere wogwiritsa ntchito, zofanana ndi China Q195-215A grade. Chikalata chachitatu C ndi chidule chozizira. Muyenera kuonetsetsa kuti mayeso a Tunsile, kumapeto kwa kalasi kuphatikizapo.
