Kupisa yakakungurutswa coiliplate yesimbi yakagadzirwa kubva kune slabs iyo inopisa uye inokungurutswa ne roughing uye kupedza zvikamu.Iyo inopisa yakakungurutswa simbi kubva paguyo yekupedzisira yeguyo yekupedzisa inotonhodzwa kusvika kune yakatarwa tembiricha nelaminar kuyerera uye yobva yabatanidzwa musimbi strip coils nemuchina wekukochekera.Iyo yakatonhodzwa simbi strip coils inogadziriswa kuita mahwendefa esimbi, flat coils uye longitudinal akachekwa simbi strip zvigadzirwa kuburikidza nemitsara yakasiyana yekupedzisa (kupfava, kutwasanudza, kugura-kucheka kana kureba kucheka, kuongorora, kuyera, kurongedza uye kumaka, nezvimwewo) zvichienderana nekusiyana kwakasiyana. zvinodiwa nevashandisi.
China ndiyo inogadzira pasi rose, inotenga uye inotengesera kunze simbi inopisa-yakakungurutswa kunze kwenyika, uye inobuda inosvika 232 miriyoni matani muna 2015. iyo inobuda uye mhando yekupisa yakatenderedzwa coil ndiro zvakare yakazadzisa zvirinani kudiwa kwekuvaka kweChina, kugadzira michina uye mamwe maindasitiri.
Simbi inopisa yakakungurutswa mucoil inowanzo sanganisira zvepakati-ukobvu hupamhi simbi mitsetse, inopisa yakakungurutswa yakatetepa yakafara simbi mitsetse uye inopisa yakakungurutswa mahwendefa matete.
Iyo yepakati-yakafara simbi tambo ndeimwe yemhando dzinomiririra zvakanyanya, kugadzirwa kwayo kwakaverengera zvikamu zviviri kubva muzvitatu zveiyo yakazara goho rehot rolled coil, iyo Shanghai Futures Exchange ichakurumidza kunyorwa muhot rolled coil remangwana kontrakiti iri pasi peiyo. mutsetse wesimbi wakafara zviri pakati nepakati.
Mutsetse wesimbi wepakati uye wakafara unoreva simbi ine hukobvu hwe ≥3 mm uye isingasviki 20 mm nehupamhi hwe ≥600 mm, inogadzirwa mune inoenderera yakafara tambo yesimbi inopisa inokungurutsa mill kana choto coil rolling mill kana zvimwe midziyo, uye inounzwa. mumakoiri.
Kupisa-yakakungurutswa yakatetepa uye yakafara tambo inoreva simbi, yeukobvu hwe<3mm uye hupamhi hwe ≥600mm, inogadzirwa ichienderera mberi yakafara mill kana muchoto wekukungurutsira kana matete mill slab, nezvimwewo, uye inounzwa mumakoiri.
Hot rolled sheet zvinoreva shizha rimwe chete resimbi rine ukobvu hwe<3 mm.Pepa rinopisa rakakungurutswa rinowanzo gadzirwa mune inoenderera yakafara mill mill, inoenderera ichikanda uye kukunguruka kweatete slabs, nezvimwewo, uye inounzwa mune pepa fomu.
Muna 2023, simbi inopisa ndiro yakakungurutswa angangoita makumi maviri emakore kubva kugadzirwa kwekugadzirwa kwakawedzera maitiro, kubva pakupera kwa2023, inopisa yakakungurutswa simbi pepa mumakoiri kugadzirwa yakasvika 291,255,600 matani, kugadzirwa kwekukura kwe11.01%.2023 inopisa yakakungurutswa coil simbi kugadzirwa kupfuura rebar (2023 kugadzirwa kwemamiriyoni mazana maviri nemakumi matanhatu ematani), yakasvetukira kumhando dzekutanga dzesimbi dzeChina.
Pamaitiro ekuchinja kwekugadzirwa kwegore negore, mumakore mashanu apfuura, kugadzirwa kwepepa rinopisa uye coil kwakaratidza kuwedzera kwegore-pagore mumamiriro ezvinhu, uye kukura kubva 2.57% muna 2019, kwakawedzera kusvika 11.01% muna 2023. , mwero wekukura wakawedzera ne8,51 muzana.
Kugadzirwa kwemwedzi nemwedzi kwesimbi inopisa yakakomberedzwa muna 2023 iri pamusoro pepamusoro-soro munhoroondo.Nekuda kwekukura kwekukura kwe11.01% muna 2023, ichipfuura huwandu hwekukura kwe3%, iyo inopisa yakakungurutswa coil simbi mill utilization rate yakawedzera kusvika 84.7%, 6.11 percent point yakakwira kupfuura muna 2022. Izvi zvinoratidza kuti musika wakakwira kugadzirwa kwemaitiro mukati megore rose.
1.Kuvaka zvivakwa: Kupisa kwakaputirwa simbi koiri inowanzoshandiswa sechinhu chekuvaka zvivakwa, sesimbi, aluminium uye galvanized simbi mashizha anoshandiswa kugadzira matenga, madziro uye pasi.Zvinhu izvi zvinowanzova nesimba rakakwirira uye kusagadzikana kwekuora uye zvinogona kusangana nezvinodiwa zvezvivakwa mumamiriro akasiyana-siyana ezvakatipoteredza.
2.Kugadzirwa kwemotokari: Mota ndeimwe nzvimbo huru yekushandisa yeHRC coils.Iwo anoshandiswa kugadzira zvinhu zvakaita semiviri yemotokari, magonhi, mahodhi, matenga uye chassis.Indasitiri yemotokari ine zvakaomesesa zvinodiwa zvezvinhu zvine simba rakawanda, kuomarara uye corrosion resistance, ese ari maitiro ekupisa akakungurutswa coil.
3.Kugadzirwa kwemidziyo yemumba: Midziyo mizhinji yemumba, yakadai sefiriji, michina yekuwachisa, ovheni yemicrowave uye maairconditioner, inoda kushandiswa kwekoiri inopisa yakamonerwa sechinhu chekugadzira.Zvinhu izvi zvinowanzoda kuve nekupedza kwakanaka kwepamusoro, pamwe nehupamhi hwema mechanical zvivakwa uye corrosion resistance.
4.Kugadzira mitoro: zvimwe zvigadzirwa zvemikwende, senge mabhokisi ealuminium, mikwende, magomba emitoro, nezvimwewo, zvakare anowanzo shandisa inopisa yakatenderedzwa coil sechinhu.Inopisa yakakungurutswa coil ikareruka, yakasimba chimiro, uye inogona kusangana nemitoro zvigadzirwa pakureruka uye kusimba kwezvinodikanwa zvezvinhu.
5.Kugadzira michina: muindasitiri yekugadzira michina, inopisa yakatenderedzwa coil inoshandiswa zvakanyanya mukugadzira michina nemidziyo yemidziyo, senge racks, kutsigira mafuremu, masiraidhi, njanji uye zvichingodaro.Zvikamu izvi zvinoda kuve nesimba rakakwirira uye kupfeka kuramba, uye HRC coils inokwanisa kuita izvi zvinodiwa.
Pakazere, hot rolled coil coil ine dzakasiyana siyana dzekushandisa mukuvaka, mota, midziyo yemumba, mabhegi nekugadzira michina.Ivo vane yakanaka mechanic zvivakwa uye corrosion resistance uye vanogona kusangana nezvinodiwa zvezvinhu muminda dzakasiyana, saka vanofarirwa zvakanyanya nevatengi.Kana uchida kutenga tenga simbi inopisa yakakungurutswa, gamuchira kuti utaure nesu.
