Anthu ambiri akamaganizira za chilengedwe chomwe amapanga, amajambula zofukiza kapena kutha kwa mankhwala. Kubowola ulusi? Mwinamwake sichinthu choyamba chimene chimabwera m'maganizo. Ndiwo malo akhungu wamba. Zomwe zimakhudzidwa sizingokhala muzinthu zomaliza zomwe zikukhala m'bokosi; Zimalukidwa muzitsulo zonse - kuchokera ku chitsulo chopangira chitsulo kupita ku nkhungu yocheka yamafuta mumlengalenga, mpaka kuzitsulo zazitsulo zomwe zimasesedwa kuchokera pansi. Ndi katundu wochulukirachulukira, nthawi zambiri amanyalanyazidwa. Popeza ndakhala pafakitale kuchokera ku Hebei kupita ku Essen, nkhani yeniyeni ili mwatsatanetsatane, kulolerana, ndi mayankho theka omwe samalowa mu malipoti okhazikika.

Zosawoneka Zoyambira: Zakuthupi ndi Mphamvu

Zimayamba ndi ndodo ya waya. Mpweya wa carbon wa chitsulo ndi chimodzi chomwe chimathandizira kwambiri. Ngati mukugwiritsa ntchito chitsulo cha ng'anjo ya okosijeni (BOF) motsutsana ndi chitsulo cha arc ng'anjo yamagetsi (EAF) kuchokera ku zinyalala, mukuyang'ana kusiyana kwa CO2 kuyeza matani pa batchi iliyonse. Malo ambiri ang'onoang'ono omangira, monga magulu aku Yongnian, m'mbiri yakale adadalira zitsulo za BOF zachigawo pamtengo wake komanso kuphweka. Mtengo wa chilengedwe unawotchedwa kuyambira pachiyambi, mtundu wa zotsatira zokonzedweratu ulusi woyamba usanakulungidwe.

Kenako pamabwera mphamvu zoyendetsera makinawo. Kupanga kozizira ndi kukulunga ulusi ndizothandiza, koma kuponya kothandizira sikuli. Ng'anjo zoyatsira, malo osambiramo a zinki, mizere yokutira ya phosphate - ndizo nkhumba zamphamvu. Ndikukumbukira pulojekiti yomwe wogulitsa wamkulu wapakati akuyesera kuwunika izi. Iwo adapeza kuti zoposa 60% ya mphamvu ya zomera zawo zimapita kumalo otentha (kutentha, kuumitsa mavuvu) osati kupanga kwenikweni. Kumeneku kunali kudzutsa. Kusintha kuchokera ku gasi wa malasha kupita ku gasi wachilengedwe kuti muwonjezeke inali sitepe, koma vuto lenileni ndilofunika kwambiri pamene mukuthamanga 24/7 kuti mukwaniritse zolinga za voliyumu.

Ndipo voliyumu ndiyofunikira apa. Mtundu wamabizinesi m'magawo okwera kwambiri ndi m'mphepete mwa lumo. Kuyika ndalama mu makina otenthetsera otenthetsera okwera kwambiri pakuwotchera kumakhala ndi nthawi yobwezera. Pamene maoda anu akusinthasintha, ndalama zogulira ndalamazo zimachedwetsedwa, mobwerezabwereza. Kusintha kwa chilengedwe ndi dongosolo la chaka chamawa mosalekeza. Ndidawonera kuzungulira uku.

The Coolant Conundrum ndi Mitsinje ya Zinyalala

Apa ndipamene zowona za shop floor zimafika. Dulani ulusi ntchito, makamaka pogogoda ndi ulusi mphero, amafuna kudula zamadzimadzi. Mafuta osungunuka akale a sukulu yakale, olemera kwambiri anali abwino kwambiri pa moyo wa zida komanso amaletsa kuphulika kwa ulusi wachitsulo chosapanga dzimbiri. Koma iwo ndi owopsa kwa zinyalala. Iwo emulsify, iwo zoipitsidwa ndi tramp mafuta ndi zitsulo particles zabwino. Sump imasanduka supu yapoizoni.

Tinayesa kusintha machitidwe a semi-synthetic ndipo pambuyo pake pafupi ndi makina owuma a MQL (Minimum Quantity Lubrication) pamizere ina ya CNC. Chiphunzitsocho chinali changwiro: kuchepetsa kumwa kwamadzi ndi 95%, kuchotsa mikangano, kupanga tchipisi tambiri touma tosavuta kukonzanso. Zoonadi? Zida zogulira zidakwera. Kwa zinthu zina zolimba kwambiri kapena zachilendo, ulusi wa ulusi sunali wofanana. Tidakumana ndi zosweka zapampopi zambiri poyambira. Kunali kusinthanitsa: mbiri yomveka bwino ya chilengedwe motsutsana ndi kukhazikika kwa ndondomeko ndi mtengo wa gawo lililonse. Zinatenga pafupifupi chaka chakusintha magawo ndikugwira ntchito ndi ogulitsa zida kuti apeze kukhazikitsidwa kokhazikika.

Zinyalala zachitsulo zomwe—zing’onozing’ono ndi zina zosafunikira kwenikweni—ndi chinthu china. Tchipisi zachitsulo zoyera, zowuma ndi chinthu chamtengo wapatali. Koma mafuta, tchipisi chonyowa? Mukulipira wina kuti awachotse, ndipo mulibe kuwoneka pang'ono komwe amathera. Ndikudziwa za machitidwe omwe adayika ma centrifugal chip wringers kuti apezenso mafuta ndikupanga tchipisi zowuma. Idapititsa patsogolo chuma chobwezeretsanso, kusandutsa malo otsika mtengo kukhala njira yaying'ono yopezera ndalama. Koma kachiwiri, ndi ndalama zam'tsogolo zomwe ambiri amalumpha.

Chithandizo cha Pamwamba: Choyipa Chofunikira

Simungathe kuyankhula za zomangira popanda kulankhula za chitetezo cha dzimbiri. Mosakayikira, iyi ndi gawo lomwe limakhudza kwambiri chilengedwe. Electroplating, makamaka plating ya zinki yokhala ndi zokutira zotembenuza chromate (yomwe ili yachikasu kapena yabuluu), imatulutsa madzi otayira odzaza ndi zitsulo zolemera, utsi wa asidi, ndi matope. Malamulo a zachilengedwe ku EU ndi North America akukankhira ku trivalent chromates kuposa hexavalent, koma malo oyeretsera madzi oipa akadali ovuta komanso okwera mtengo kuyendetsa bwino.

Ndayendera malo omwe adatulutsa zida zonse, ndikukankhira vuto kutsika kwa ogulitsa apadera. Izi zitha kuyeretsa lipoti lanu latsamba lanu, koma sizichepetsa kukhudzidwa kwadongosolo lonse. Ena, monga ena mwa opanga ophatikizika kwambiri pazoyambira zazikulu zaku China, abweretsa mnyumba kuti aziwongolera. Mwachitsanzo, kampani ngati Malingaliro a kampani Handan Zitai Fastener Manufacturing Co., Ltd., omwe akugwira ntchito kuchokera kugawo lalikulu la Yongnian, angakumane ndi chisankhochi mwachindunji. Kukhala pafupi ndi misewu yayikulu ngati Beijing-Shenzhen Expressway ndikofunikira pamayendedwe, komanso kuwayika m'dera lomwe likuwunika kwambiri zachilengedwe. Chisankho pakati pa kumanga malo opangira chithandizo chamakono, otsekedwa ndi kudalira munthu wina ndi njira ya madola mamiliyoni ambiri, zomwe zimakhudza mtengo ndi kutsata.

Njira zina monga zokutira zamakina (zigawo zing'onozing'ono) kapena zokutira zatsopano zayamba kufalikira. Amapewa zitsulo zolemera. Koma amabwera ndi kusinthanitsa kwa magwiridwe antchito pa maola oyeserera amchere kapena ma coefficients a ulusi. Kutsimikizira kasitomala wamagalimoto kapena omanga kuti avomereze zokutira zatsopano, zobiriwira zitha kukhala zaka zambiri zoyenerera. Ubwino wa chilengedwe nthawi zambiri umayimitsidwa ndi miyezo yokhazikika yaukadaulo.

Logistics ndi Lifecycle Blind Spot

Aliyense amayesa kutulutsa kwa zipata za fakitale yake. Ochepa amayang'ana kwathunthu mtengo wa kaboni wopezera zinthu zopangira ndi zomalizidwa kubowola ulusi katundu kunja. Malo omwe ali pafupi ndi Beijing-Guangzhou Railway ndi othandiza kwambiri ku kampani ngati Zitai, zomwe zimapangitsa kuti anthu azitha kusintha kuchoka kumsewu kupita ku njanji kuti azinyamula katundu wambiri. Kunyamula njanji kumatha kuchepetsa mpweya ndi 75% poyerekeza ndi magalimoto. Koma pamafunika kukonzekera, kuchuluka, ndi njira yoyenera. Si nthawi zonse kusankha kosasintha kwa zotumiza mwachangu, zazing'ono.

Ndiye pali mapeto a moyo wa mankhwala. Chomangira chitsulo muzitsulo, mwachidziwitso, chikhoza kubwezeretsedwanso bwino pamodzi ndi chimango. Koma mukuchita? Ngati ndi chomangira chomata, chophimbacho chikhoza kuwononga chitsulo chosungunuka. Ngati ndi ulusi wachitsulo chosapanga dzimbiri, zinthu zophatikizika monga faifi tambala kapena chromium zimasokoneza mtsinje wobwezeretsanso. Zoyenera kuchokera kuzinthu zozungulira zachuma zingakhale mapangidwe a disassembly ndi mitsinje yoyera yazinthu. Izi ndizotalikirana ndi zenizeni za bolt ya nangula yokhala ndi konkriti kapena thupi lagalimoto lophwanyidwa kukhala shredder. Zotsatira za chilengedwe zimachedwetsedwa, osati kuthetsedwa.

Zopanikizika Zothandiza ndi Zopindulitsa Zowonjezera

Kotero, kodi zonsezo ndi chiwonongeko? Osati ndendende. Kupanikizika kukubwera kuchokera kumakona angapo tsopano. Si owongolera okha; ndimakasitomala akumayiko osiyanasiyana omwe akufuna data ya kaboni pazakudya zawo za Scope 3. Amafuna kudziwa phazi la gawo lililonse, mpaka chochapira chomaliza. Izi zikukakamiza kuwonekera pansi pa unyolo. Ndakhala m'gulu la zowunikira zomwe mukuyenera kupereka ndalama zothandizira, ziphaso zakuthupi, ndi ziwonetsero za zinyalala. Ndizotopetsa koma zimayendetsa kusintha.

Zopindulitsa nthawi zambiri zimakhala zowonjezereka, osati zosintha. Ndizokhudza kukhathamiritsa njira yomwe muli nayo. Zinthu zosavuta: kukhazikitsa ma frequency frequency drives (VFDs) pamapampu onse ndi ma compressor motors kuti agwirizane ndi katundu. Kutenga kutentha kwa zinyalala kuchokera ku ng'anjo kupita ku preheat madzi ochapira. Kuphatikiza ma plating batches kuti achulukitse kugwiritsa ntchito tanki ndikuchepetsa kutulutsa kwamankhwala. Izi ndi zosasangalatsa, zosinthika zomwe zimawonjezera. Iwo samapanga kutulutsa kwakukulu kwa atolankhani, koma amasuntha singano pansi.

Kuyang'ana patsamba la wopanga, monga zitaifsteners.com, mutha kuwona ziphaso ngati ISO 14001. Ndilo chimango. Koma kuyesa kwenikweni ndizomwe zimachitika Lachiwiri masana pomwe mzere wopanga utsikira, ndipo kukonza mwachangu kumaphatikizapo kudutsa makina osefera kuti akwaniritse nthawi yotumiza. Kuwonongeka kwa chilengedwe kumayendetsedwa mu nthawi za kukakamizidwa, ndi chikhalidwe pansi, osati ndondomeko yokhayokha.

Pomaliza, a chilengedwe wa ulusi kubowola ndi chiŵerengero cha zikwi zisankho zazing'ono. Zili mu kusankha kwa gwero lachitsulo, ndondomeko yokonza makina ozizira, kutentha kwa uvuni wowumitsa, ndi njira yoyendera yosankhidwa. Palibe chipolopolo chimodzi chasiliva, kungokhala kovuta, kugwira ntchito mosalekeza kupanga chilichonse mwazosankhazo kukhala chosawononga pang'ono, ndikupanga gawo lomwe limagwirizanitsa dziko lapansi. Ndicho chenicheni chosokoneza, chosasangalatsa cha izo.
