Ikhoyili eshushu ephothiweyoipleyiti yentsimbi eyenziwe kwii-slabs ezifudumalayo kwaye ziqengqeleke ngamayunithi anqabileyo kunye nokugqiba.Umcu wentsimbi oshushu oqengqelekayo osuka kwilitye lokugqibela lokugqiba upholiswa kwiqondo lobushushu elibekiweyo ngokuqukuqela kwe-laminar kwaye emva koko udityaniswe kwiikhoyili zentsimbi ngomatshini wokubopha.Iikhoyili zentsimbi ezipholileyo zicutshungulwa kwiipleyiti zetsimbi, iikhoyili ezisicaba kunye neemveliso zentsimbi ezisikiweyo zexesha elide ngokusebenzisa imigca yokugqiba eyahlukeneyo (i-flattening, i-straightening, i-cross-cutting okanye i-longitudinal cutting, ukuhlola, ukulinganisa, ukupakishwa kunye nokumakishwa, njl njl.) iimfuno zabasebenzisi.
I-China ngowona mvelisi mkhulu wehlabathi, umthengi kunye nomthengisi wentsimbi eshushu eqengqelekayo, enemveliso efikelela kwi-232 yezigidi zeetoni ngo-2015. imveliso kunye nomgangatho wepleyiti yekhoyili esongwe eshushu ikwakhawulelana ngcono nemfuno ekhulayo yolwakhiwo lwaseTshayina, ukwenziwa koomatshini kunye namanye amashishini.
Intsimbi eshushu esongwayo kwikhoyili ngokubanzi ibandakanya ukutyeba okuphakathi okubanzi okuphakathi kwemicu yentsimbi, imicu yentsimbi eshushu ebhityileyo ebanzi kunye neepleyiti ezibhityileyo ezishushu.
Umtya wentsimbi obunzima obuphakathi obubanzi obuphakathi ngomnye weentlobo ezimele kakhulu, imveliso yawo ibalelwa malunga nesibini kwisithathu semveliso epheleleyo yekhoyili eshushu eqengqelekayo, iShanghai Futures Exchange kungekudala iza kudweliswa kwikhontrakthi eshushu eqengqelekayo yekhoyili ephantsi. umcu wentsimbi enobukhulu obuphakathi.
Umtya wentsimbi otyebileyo ophakathi kunye nobubanzi buthetha umcu wentsimbi onobukhulu obuyi-≥3 mm nangaphantsi kwe-20 mm kunye nobubanzi obuyi-≥600 mm, uveliswe kuluhlu oluqhubekayo lwentsimbi yokusila eshushu yokusila okanye i-coil yokusila okanye ezinye izixhobo, kwaye zisiwe. kwiikhoyili.
I-Hot-rolled thin and wide strip ithetha intsimbi, enobunzima obuyi-<3mm kunye nobubanzi obuyi-≥600mm, eveliswe kwii-mills eziqhubekayo ze-strip strip okanye i-furnace rolling mill okanye i-slab mill ebhityileyo, njl. njl., kwaye ihanjiswe ngeekhoyili.
Ishiti eliqengqelekayo elishushu lithetha icwecwe elinye lentsimbi elinobukhulu obuyi<3 mm.Iphepha elishushu eliqengqelekayo lidla ngokuveliswa kwii-mills eziqhubekayo ezibanzi, ukuphosa okuqhubekayo kunye nokuqengqeleka kwamacwecwe amancinci, njl.
Ngo-2023, ipleyiti yentsimbi eshushu yaqengqeleka phantse kumashumi amabini eminyaka ukususela kwimo yokuvelisa imveliso yanda, ukususela ekupheleni kuka-2023, intsimbi eshushu yaqengqeleka kwimveliso yeekhoyili yafikelela kwiitoni ezingama-291,255,600, izinga lokukhula kwemveliso ye-11.01%.2023 eshushu yaqengqeleka coil imveliso yentsimbi ngaphezu rebar (2023 imveliso yeetoni ezigidi ezingama-260), watsibela kwiindidi zentsimbi yokuqala enkulu China.
Kwimeko yotshintsho lwemveliso yonyaka, kule minyaka mihlanu idlulileyo, ukuveliswa kwephepha elishushu eliqengqelekayo kunye nekhoyili kubonise ukonyuka konyaka nonyaka, kwaye izinga lokukhula ukusuka kwi-2.57% ngo-2019, linyuke laya kutsho kwi-11.01% ngo-2023. , izinga lokukhula linyuke ngepesenti ezisi-8,51.
Imveliso yenyanga yentsimbi edibeneyo eshushu edibeneyo ngo-2023 ingaphezulu kweyona nqanaba liphezulu kwimbali.Ngenxa yezinga lokukhula kwemveliso ye-11.01% ngo-2023, igqithise kakhulu isantya sokukhula kwe-3%, isantya sokusetyenziswa kwe-coil coil coil inyuke ukuya kuma-84.7%, ipesenti ye-6.11 yamanqaku aphezulu kunowama-2022. Oku kubonisa ukuba imarike iphezulu imo yemveliso ngokusisiseko unyaka wonke.
1.Izakhiwo zokwakha: Iintsimbi ezitshisayo ezitshisiweyo zisetyenziswa ngokuqhelekileyo njengezinto zokwakha izakhiwo, ezifana nentsimbi, i-aluminium kunye ne-galvanized sheet sheets esetyenziselwa ukwenza uphahla, izindonga kunye nemigangatho.Ezi zixhobo zihlala zinamandla aphezulu kunye nokumelana nokubola kwaye zinokuhlangabezana neemfuno zezakhiwo kwiimeko ezahlukeneyo zokusingqongileyo.
2.Ukwenziwa kweemoto: Iimoto yenye indawo enkulu yesicelo kwiikhoyili ze-HRC.Zisetyenziselwa ukwenza izinto ezifana nemizimba yemoto, iingcango, iihood, uphahla kunye ne-chassis.Umzi-mveliso weemoto uneemfuno ezingqongqo kakhulu zezixhobo ezinamandla aphezulu, ukuqina kunye nokumelana nokugqwala, zonke ezo ziyimpawu zekhoyili eshushu.
3.Ukwenziwa kwezixhobo zasekhaya: Izixhobo ezininzi zekhaya, ezinjengeefriji, oomatshini bokuhlamba, ii-oveni zemicrowave kunye ne-air conditioner, zifuna ukusetyenziswa kwekhoyili eshushu njengesixhobo sokwakha.Ezi zixhobo zidla ngokufuneka ukuba zibe nomgangatho omhle wokugqitywa, kunye neempawu eziphezulu zoomatshini kunye nokumelana nokubola.
4.Ukwenziwa kwemithwalo: ezinye iimveliso zemithwalo, ezifana neebhokisi ze-aluminium, imithwalo, iigobolondo zemithwalo, njl.Ikhoyili egobileyo eshushu ilula, isakhiwo esomeleleyo, kwaye sinokuhlangabezana nemveliso yemithwalo ekukhanyeni kunye nokomelela kweemfuno zezinto.
5.Ukwenziwa koomatshini: kumashishini okuvelisa oomatshini, i-coil eshushu edibeneyo isetyenziswa ngokubanzi ekwenzeni oomatshini kunye nezixhobo zezixhobo, ezifana neeracks, iifreyimu zenkxaso, izilayidi, iileyili kunye nokunye.La malungu kufuneka abe namandla aphezulu kunye nokumelana nokunxiba, kwaye iikhoyili ze-HRC ziyakwazi ukuhlangabezana nezi mfuno.
Lilonke, iikhoyili ezisotyiweyo ezishushu zineendlela ezininzi zokusetyenziswa kulwakhiwo, iimoto, izixhobo zasekhaya, iingxowa kunye nokuveliswa koomatshini.Baneepropathi ezilungileyo zoomatshini kunye nokumelana nomhlwa kwaye banokuhlangabezana nemfuno yemathiriyeli kwimimandla eyahlukeneyo, ke bathandwa kakhulu ngabathengi.Ukuba ufuna ukuthenga uthenge intsimbi eshushu eqengqelekayo, wamkelekile ukuba uqhagamshelane nathi.
