Ikhoyili egoqiwe eshisayoipuleti lensimbi elenziwe ngama-slabs ashisisayo futhi agingqelwe ngamayunithi ama-roughing kanye nokuqeda.Umucu wensimbi ogoqiwe oshisayo osuka emshinini wokugcina wesigayo upholiswa kumazinga okushisa amisiwe ngokugeleza kwe-laminar bese ugoqwa ube amakhoyili emicu yensimbi ngomshini wokugoqa.Amakhoyili wensimbi apholile acutshungulwa abe amapuleti ensimbi, amakhoyili ayisicaba kanye nemikhiqizo yomugqa wensimbi osikiwe ubude ngemigqa ehlukene yokuqedela (ukwenza isicaba, ukuqondisa, ukusika okuphambene noma ukusika ubude, ukuhlola, ukukala, ukupakisha nokumaka, njll.) ngokuya ngokuhlukile izidingo zabasebenzisi.
I-China ingumkhiqizi, umthengi kanye nomthumeli wensimbi omkhulu kunawo wonke emhlabeni, ophumayo ufinyelele amathani ayizigidi ezingama-232 ngo-2015. umkhiqizo kanye nekhwalithi ye-hot rolling coil plate nayo isihlangabezane kangcono nesidingo esikhulayo sokwakha, ukukhiqizwa kwemishini nezinye izimboni zaseChina.
Insimbi egoqiwe eshisayo ekhoyili ngokuvamile ihlanganisa imichilo yensimbi enogqinsi olumaphakathi, imichilo yensimbi egoqiwe eshisayo ebanzi kanye namapuleti ashisayo asongwe amancane.
I-medium-thickness wide wide steel strip ingenye yezinhlobo ezimele kakhulu, ukukhiqizwa kwayo kwenze cishe izingxenye ezimbili kwezintathu zengqikithi yomkhiqizo wekhoyili egoqiwe eshisayo, iShanghai Futures Exchange izofakwa maduze ohlwini lwenkontileka yekhoyili egoqiwe engaphansi engaphansi. umugqa wensimbi owugqinsi obanzi.
Umugqa wensimbi owugqinsi obanzi nobanzi uchaza umucu wensimbi onogqinsi ≥3 mm nangaphansi kuka-20 mm nobubanzi obungu-≥600 mm, okhiqizwa ngomshini oqhubekayo obanzi wensimbi oginqayo noma izigayo zokugingqa ikhoyili yesithando somlilo noma ezinye izinto zokusebenza, futhi zilethwe. emakhoyili.
Umugqa ogoqwe oshisayo ozacile nobanzi usho umucu wensimbi, owugqinsi ongu-<3mm nobubanzi obungu-≥600mm, okhiqizwa ngezigayo zemigqa ebanzi eqhubekayo noma izigayo zokugoqa zesithando somlilo noma izigayo ze-slab ezizacile, njll., futhi zilethwe ngamakhoyili.
Ishidi eligoqiwe elishisayo lisho ishidi elilodwa lensimbi elinogqinsi olungu-<3 mm.Ishidi eligoqiwe elishisayo livame ukukhiqizwa ngomshini wokugaya obanzi oqhubekayo, ukusakaza okuqhubekayo nokugoqeka kwama-slabs azacile, njll., futhi alethwe ngefomu leshidi.
Ngo-2023, ipuleti lensimbi elishisayo lagoqa cishe amashumi amabili eminyaka kusukela amandla okukhiqiza ekhuphuka imodi, kusukela ekupheleni kuka-2023, ishidi lensimbi elishisayo ekukhiqizeni amakhoyili lafinyelela amathani angu-291,255,600, izinga lokukhula kokukhiqizwa kwe-11.01%.Ukukhiqizwa kwensimbi yekhoyili egoqiwe ka-2023 engaphezulu kwe-rebar (ukukhiqizwa kuka-2023 kwamathani ayizigidi ezingama-260), kugxumele ezinhlotsheni zensimbi zokuqala ezinkulu zaseChina.
Ngokuthambekela kwezinguquko zokukhiqiza zaminyaka yonke, eminyakeni emihlanu edlule, ukukhiqizwa kweshidi eligoqelwe elishisayo kanye nekhoyili kubonise ukwanda konyaka nonyaka, futhi izinga lokukhula lisuka ku-2.57% ngo-2019, lenyuke laya ku-11.01% ngo-2023. , izinga lokukhula lenyuke ngamaphesenti angu-8,51.
Ukukhiqizwa kwanyanga zonke kwensimbi egoqiwe eshisayo ngo-2023 kungaphezu kwezinga eliphakeme kakhulu emlandweni.Ngenxa yokukhula kwezinga lokukhiqiza ngo-11.01% ngo-2023, elidlule kakhulu izinga lokukhula kwamandla ka-3%, izinga lokusebenzisa amandla ensimbi yensimbi eshisayo likhuphuke lafinyelela ku-84.7%, ngamaphesenti angu-6.11 ngaphezu kwango-2022. Lokhu kukhombisa ukuthi imakethe iphezulu imodi yokukhiqiza ngokuyisisekelo unyaka wonke.
1.Izakhiwo zokwakha: Amakhoyili ensimbi ashisayo ajwayele ukusetshenziswa njengempahla yokwakha, njengensimbi, i-aluminium namashidi ensimbi asetshenziselwa ukwenza uphahla, izindonga kanye naphansi.Lezi zinto ngokuvamile zinamandla aphezulu kanye nokumelana nokugqwala futhi zingahlangabezana nezidingo zezakhiwo ezimweni ezihlukahlukene zemvelo.
2.Ukukhiqiza izimoto: Izimoto zingenye indawo enkulu esetshenziselwa amakhoyili e-HRC.Asetshenziselwa ukwenza izingxenye ezifana nemizimba yemoto, iminyango, ama-hood, uphahla kanye ne-chassis.Imboni yezimoto inezidingo eziqinile kakhulu zezinto ezinamandla amakhulu, ukuqina nokumelana nokugqwala, konke okuyizici zekhoyili egoqiwe eshisayo.
3.Ukukhiqiza izinto zikagesi zasekhaya: Imishini eminingi yasendlini, njengeziqandisi, imishini yokuwasha, amahhavini ama-microwave nama-air conditioner, idinga ukusetshenziswa kwekhoyili egoqiwe eshisayo njengempahla yesakhiwo.Lezi zinto ngokuvamile zidinga ukuba nesiphetho esihle, kanye nezakhiwo eziphezulu zemishini kanye nokumelana nokugqwala.
4.Ukukhiqiza imithwalo: eminye imikhiqizo yemithwalo, efana namabhokisi e-aluminium, imithwalo, amagobolondo emithwalo, njll., ivamise ukusebenzisa ikhoyili egoqiwe eshisayo njengento esetshenziswayo.Ikhoyili egoqiwe eshisayo iyisakhiwo esilula, esiqinile, futhi ingahlangabezana nemikhiqizo yemithwalo ngokukhanya namandla ezidingo zezinto ezibonakalayo.
5.Ukukhiqiza imishini: embonini yokukhiqiza imishini, ikhoyili egoqiwe eshisayo isetshenziswa kakhulu ekwenzeni izingxenye zemishini nemishini, njengama-rack, amafreyimu okusekela, ama-slider, ama-rails nokunye.Lezi zingxenye zidinga ukuba namandla aphezulu kanye nokungagugi, futhi amakhoyili e-HRC ayakwazi ukuhlangabezana nalezi zidingo.
Sekukonke, amakhoyili amakhoyili ashisayo anemisebenzi eminingi eyahlukene ekwakheni, kwezezimoto, kwempahla yasendlini, izikhwama kanye nokukhiqizwa kwemishini.Zinezakhiwo ezinhle zemishini nokumelana nokugqwala futhi zingahlangabezana nesidingo sezinto zokwakha emikhakheni ehlukene, ngakho-ke zithandwa kakhulu ngamakhasimende.Uma ufuna ukuthenga thenga insimbi egoqiwe eshisayo, wamukelekile ukusithinta.
