- Chii chinotonhora chakakungurutswa coil
Cold rolled coil, inozivikanwawo seCRC, imhando yechigadzirwa chesimbi chinogadzirwa nesimbi inopisa yakakungurutswa uye inoratidzwa nehutema hudiki uye mashandisirwo chaiwo.
Simbi inotonhorera inoreva simbi yakaderera-kabhoni inogadzirwa ne "inotonhora rolling" nzira uye inogadziriswa padyo neyakajairwa kamuri tembiricha.Cold-rolled steel inopa simba repamusoro uye machinability.Mashizha esimbi anotonhora anowanzo shandiswa kune zvigadzirwa zveinjiniya uko kushivirira kwakasimba, concentricity, kutwasanuka uye yakavharwa nzvimbo inodiwa.
Simbi inotonhora-yakakungurutswa inogadzirwa mumagiyo ekuderedza kutonhora uko zvinhu zvinotonhodzwa padyo nekamuri tembiricha, zvichiteverwa neannealing uye/kana hasha dzichikunguruka.Iyi nzira inogadzira simbi ine huwandu hwakasiyana hwekupedzisa kwepamusoro uye yakakwirira mukushivirira, concentricity, uye kutwasanuka zvichienzaniswa nesimbi yakakungurutswa.Simbi inotonhorwa ine kabhoni yakaderera, uye nzira yekumisikidza inoita kuti ive yakapfava pane shizha rinoputika.Zvigadzirwa zvesimbi zvinotonhora zvinowanzogadzirwa mumashiti, mitsetse, mbariro uye tsvimbo.
2.Cold-yakakungurutswa coil classification, chigadzirwa renji uye zvivakwa
Miyero inoshandiswa munyika dzakasiyana-siyana kumisa zvinodiwa zvesimbi inotonhora, se EN 10130, EN 10268, EN 10209, ASTM A1008 / A1008M, DSTU 2834, GOST 16523, GOST 9045, GOST 17066 simbi uye mamwe magiredhi. saizi masaizi echando-akakungurutswa coils, kunyorera kwavo (profiling, kutonhora kuumba, enamelling, general kushandiswa, nezvimwewo), michina zvivakwa, pamusoro pemhando uye mamwe ma paramita.
3.Cold-rolled coils maererano neEuropean standards
Iwo anonyanya kuteverwa eEuropean maitiro ekugadzira anotonhora-akatenderedzwa makoiri ndeye EN 10130, EN 10268 uye EN 10209.
EN 10130 inoshandiswa kumakoiri anotonhora akakungurutswa akagadzirwa neakadzika-kabhoni DC01, DC03, DC04, DC05, DC06 uye DC07 magiredhi esimbi ekugadzira inotonhora pasina kupeta, ane hurefu hushoma hwe600 mm uye ukobvu hushoma hwe0.35 mm.
4.Zvimiro zveCold Rolled Coil
Mamiriro makuru emakoiri anotonhora anotenderedza anosanganisira kwakaringana kushivirira kwedimensional, yakakwidziridzwa michina, uye nani pamusoro pemhando yepamusoro pane inopisa-yakatenderedzwa mapepa.
Cold rolling inoitawo kuti zvikwanise kugadzira simbi dzakatetepa mashizha asingakwanise kugadzirwa mumagiyo anopisa.Iwo maindasitiri makuru anoshandiswa kutonhora-akatenderedzwa coils anosanganisira kuvaka muchina, zvinhu zvevatengi, kuvaka, mota.Kana zvasvika kune indasitiri yekuvaka, inotonhora-yakatenderedzwa coils inonyanya kushandiswa kugadzira façade zvinhu, zvivakwa zvesimbi, akabhenda akavharwa uye akavhurika profiles, nezvimwe.
JINBAICHENG kupadzakasiyana-siyana zvinopihwa kuti iwe ukwidze zvese zvigadzirwa zvako uye maitiro.
