Chii chinonzi hot-rolled, chii chinonzi cold-rolled, uye musiyano uripo pakati pezviviri izvi?

 

1. Kupisa Kunotenderera
Kuramba uchikanda slabs kana kutanga kutenderera slabs sezvinhu zvakagadzirwa, zvinodziiswa nechoto chinodziya nedanho, mvura inomanikidzwa yakawanda inobviswa phosphorization mu roughing mill, roughing zvinhu nekucheka musoro, muswe, uye wobva wapinda mu finishing mill, kushandisa computer-controlled rolling, final rolling iri mushure mekutonhodza kwe laminar flow (computer-controlled cooling rate) uye coiling machine coiling, zvinova straight hair rolls. Musoro nemuswe we straight hair coil unowanzova rurimi ne fishtail chimiro, ukobvu, upamhi hwakarurama hushoma, kazhinji kune wave-shaped edge, folded edge, tower nezvimwe zvikanganiso. Vhoriyamu yayo inorema, dhayamita yemukati ye steel coil i760mm. (General pipe making industry inoda kushandisa.) straight hair coil nekucheka musoro, muswe, cutting edge uye kupfuura imwe chete kutwasanudza, leveling uye mamwe finishing line processing, wobva wacheka plate kana re-roll, ndiko kuti: hot rolled steel plate, flat hot hot rolled steel coils, longitudinal cut strip nezvimwe zvigadzirwa. Hot rolled finishing coils kana pickling kubvisa oxide ganda uye oiling mu hot rolled pickled coil. Mufananidzo uri pazasi unoratidzakoiri inopisa yakamonerwa.

 

2. Yakaputirwa nechando
Masimbi anomonerwa nesimbi anopisa sezvinhu zvakabikwa, mushure mekunamirwa kubvisa ganda re oxide kuti ritonhore, chigadzirwa chakapedzwa chevhoriyamu yakaoma yakamonerwa, nekuda kwekushanduka-shanduka kwechando kunoramba kuripo kunokonzerwa nekuomarara kwevhoriyamu yakaoma yakamonerwa, kuomarara, kuomarara uye kudzikira kwezviratidzo zvepurasitiki, kushatisa mashandiro esimbi, zvinogona kushandiswa chete pakuchinja-chinja kuri nyore kwezvikamu. Masimbi akaoma akamonerwa anogona kushandiswa sezvinhu zvakabikwa zvechigadzirwa che galvanizing chinodziya, nekuti chigadziko che galvanizing chinodziya chakaiswa nemutsara we annealing. Kurema kwe coil yakaoma yakamonerwa kazhinji i6 ~ 13.5 matani, dhayamita yemukati ye coil i610mm. Plate yakamonerwa nechando yakawanda, coil inofanira kunge iri continuous annealing (CAPL unit) kana hooded furnace de-annealing treatment, kubvisa kuomarara kwechando uye kusvetukira, kuti uwane hunhu hwemakanika hwakatarwa muzviratidzo zvakajairwa. Hunhu hwepamusoro hweplate yesimbi yakamonerwa nechando, chitarisiko, kurongeka kwehukuru zviri nani pane plate yakamonerwa nechando. Mufananidzo unotevera unoratidzakoiri yakamonerwa inotonhora.

 

Musiyano mukuru uripo pakati pesimbi yakakungurutswa inotonhora vs simbi inopisa yakakungurutswaZviri muhunyanzvi hwekugadzirisa, huwandu hwekushandiswa, hunhu hwemakanika uye mhando yechinhu, pamwe nekusiyana kwemitengo. Zvinotevera ndizvo zvinotsanangurwa zvakadzama:
Kugadziriswa. Kupfungaira kunopisa kunoitwa pakupisa kwakanyanya, ukuwo kupfungaira kunotonhora kunoitwa pakupisa kwemumba. Kupfungaira kunopisa kunopfuura tembiricha yekristaro, ukuwo kupfungaira kunotonhora kunopfuura tembiricha yekristaro.

 
Mashandisirwo: Simbi inoputirwa inopisa inonyanya kushandiswa muzvivakwa zvesimbi kana zvikamu zvemakanika, kusanganisira kuvaka mabhiriji, nepo simbi inoputirwa inotonhora ichinyanya kushandiswa muindasitiri yemotokari kana midziyo midiki, michina yekuwachisa, firiji, nezvimwewo, kusanganisira zvinhu zvekuvaka.

 
Hunhu hwemakanika. Hunhu hwemakanika hwakaputirwa nechando hunowanzova nani pane hunoputirwa nechando, nekuti maitiro ekuputirwa nechando anoita kuti pave nekuomarara kana kuti kuomarara kunotonhora, zvichikonzera kuomarara uye simba repamusoro pepepa rakaputirwa nechando rakakwirira, asi kuomarara kwacho kwakaderera, nepo hunhu hwemakanika hwepepa rakaputirwa nechando hwakaderera pane pepa rakaputirwa nechando, asi hune kusimba uye ductility iri nani.

 
Hunhu hwepamusoro. Hunhu hwechimiro chesimbi inotonhorera inotonhora huchava nani pane simbi inotonhorera inopisa, zvigadzirwa zvinotonhorera zvinotonhora zvakaoma uye zvishoma, nepo zvigadzirwa zvinotonhorera zvinopisa zvine pamusoro wakaomarara uye une magadzirirwo akaomarara.

 
Ukobvu hwemagadzirirwo. Makoiri akaputirwa anotonhora anowanzova matete pane makoiri akaputirwa anodziya, ukobvu hwemakoiri akaputirwa anodziya hunobva pa0.3 kusvika 3.5 mamilimita, nepo makoiri akaputirwa anodziya ari pakati pe1.2 kusvika 25.4 mamilimita.

Mutengo: Kazhinji, kuputira kunotonhora kunodhura zvishoma pane kuputira kunodziya. Izvi zvinodaro nekuti kuputira kunodziya kunoda kushandiswa kwemichina yekugadzira yakanyanya kunaka uye tekinoroji yakaoma yekushanda, uye kuputira kunodziya kunogona kuwana mhedzisiro iri nani yekurapa pamusoro, saka mhando yezvigadzirwa zvinoputira zvinodziya inowanzo kuve yakakwira, mutengo wacho wakakwirawo. Pamusoro pezvo, simbi inoputira inodziya mukugadzira inoda tekinoroji yakaoma yekugadzirisa uye kuoma kwekugadzirisa kwakanyanya, zvinodiwa zvemichina yekugadzira, maroli nezvimwe zvekushandisa zvakakwirira, izvo zvichatungamirawo kukwira kwemitengo yekugadzira.
