Xa uninzi lwabantu lucinga malunga nemeko yendalo esingqongileyo yokuvelisa, bafanekisela imisi okanye imichiza ebalekayo. Drula imisonto? Mhlawumbi ayisiyiyo into yokuqala ethi qatha engqondweni. Leyo yindawo eyimfama eqhelekileyo. Impembelelo ayikho nje kwimveliso yokugqibela ehleli kwibhokisi; ilukiweyo kuyo yonke inkqubo yekhonkco-ukusuka kwi-coil yensimbi eluhlaza ukuya kwi-oyile yokusika inkungu emoyeni, ukuya kutsho kwiintsimbi zetsimbi ezitshayelwe kumgangatho wokusebenzela. Luxanduva olongezelekayo, oluhlala lungahoywa. Ukuhlala kwimigangatho yefektri ukusuka e-Hebei ukuya e-Essen, ibali lokwenyani likwiinkcukacha zegranular, ukulungelelana, kunye nesiqingatha sezisombululo ezingazange zingene kwiingxelo zokuzinza ezicwebezelayo.

Isiseko esiNgabonwayo: Izinto ezikrwada kunye namandla

Iqala ngentonga yocingo. I-carbon footprint yentsimbi yeyona nto inegalelo elikhulu. Ukuba usebenzisa isiseko se-oxygen furnace (BOF) intsimbi versus electric arc furnace (EAF) steel from scrap, ujonge umahluko weCO2 olinganiselwa kwiitoni ngebhetshi nganye. Uninzi lweehabhu zokuqhobosha ezincinci, ezinje ngamaqela aseYongnian, ngokwembali bezixhomekeke kwintsimbi ye-BOF yengingqi ngeendleko kunye nokulula kokubonelela. Iindleko zokusingqongileyo zabhakwa kwasekuqaleni, uhlobo lwempembelelo elungiselelwe kwangaphambili ngaphambi kokuba intambo yokuqala ihlanganiswe.

Emva koko kuza amandla okuqhuba oomatshini. Ukubunjwa okubandayo kunye nokuqengqeleka kwentambo kuyasebenza, kodwa i-cast cast ayinjalo. Iziko lokutshisa i-annealing, i-zinc plating bath, i-phosphate coating lines-ziyi-hogs zamandla. Ndikhumbula iprojekthi enomthengisi ophakathi ezama ukuphicotha oku. Baye bafumanisa ukuba ngaphezu kwe-60% yotsalo lwamandla esityalo sabo baye kwiinkqubo zokushisa (unyango lobushushu, i-ovens yokomisa) kwaye kungekhona ukubunjwa kwangempela. Ibiluvuso olo. Ukutshintshela kwirhasi yamalahle ukuya kwirhasi yendalo yokutsala yayilinyathelo, kodwa owona mceli mngeni ngumthwalo wesiseko xa uqhuba i-24/7 ukuhlangabezana nokujoliswe kuko umthamo.

Kwaye umthamo ngundoqo apha. Imodeli yoshishino kwiindawo ezisemgangathweni ophezulu ziyi-razor-thin margins. Ukutyala imali kwi-high-effective induction heat system for annealing inexesha lokubuyisela. Xa incwadi yakho yoku-odola iguquguquka, loo nkcitho inkulu iye irhoxiswe, kwakhona kwaye kwakhona. Ukuphuculwa kokusingqongileyo sisicwangciso sonyaka ozayo ngokuqhubekayo. Ndiwubonele lo mjikelo.

I-Conundrum ePholisayo kunye nemijelo yeNkunkuma

Apha kulapho ubunyani bomgangatho wevenkile bubetha khona. Intambo yokuqhuba imisebenzi, ngakumbi ukucofa kunye nokugaya intambo, kufuna ulwelo lokusika. Isikolo esidala, ii-oyile ezinyibilikayo ezisindayo zazimnandi kubomi besixhobo kwaye zithintela ukurhawuka kwimisonto yentsimbi. Kodwa ziyiphupha elibi lonyango lwenkunkuma. Benza emulsify, badyobhekile ngeoyile yetramp kunye neentsimbi ezicolekileyo. I-sump ijika ibe yisuphu enetyhefu.

Sizame ukutshintshela kwiinkqubo ze-semi-synthetic kwaye kamva kufuphi ne-MQL eyomileyo (i-Minimum Quantity Lubrication) kwiinkqubo kwezinye imigca ye-CNC. Ithiyori yayigqibelele: nciphisa ukusetyenziswa kolwelo ngama-95%, susa ukungcola, dala iitshiphusi ezomileyo ekulula ukuzisebenzisa kwakhona. Yinyani? Iindleko zezixhobo zinyukile. Kwezinye izinto eziphakamileyo okanye ezingaqhelekanga, umgangatho wentambo awuzange uhambelane. Siye sajongana nokuqhekeka kwempompo ngakumbi ekuqaleni. Yayilurhwebo: inkangeleko yemo engqongileyo ecacileyo ngokuchasene nozinzo lwenkqubo kunye neendleko-ngenxalenye. Kuthathe phantse unyaka wokulungisa iiparamitha kunye nokusebenza nabathengisi bezixhobo ukufumana ukuseta okuzinzileyo.

Inkunkuma yesinyithi ngokwayo-i-swarf kunye ne-off-spec parts-yenye into. Iitshiphu zentsimbi ezicocekileyo, ezomileyo ziyimpahla yorhwebo. Kodwa iitshiphusi ezinamafutha, ezimanzi? Uhlawula umntu ukuba azithathe, kwaye unokubonakala okuncinci apho aphelela khona. Ndiyazi ngemisebenzi efakele i-centrifugal chip wringers ukubuyisela ioyile kunye nokuvelisa iitshiphusi ezomileyo. Iphucule uqoqosho lokuphinda isetyenziswe, ijika iziko leendleko libe yingeniso encinci. Kodwa kwakhona, lutyalo-mali lwangaphambili abaninzi abalutsibayo.

Unyango lwangaphandle: Ububi obuyimfuneko

Awukwazi ukuthetha malunga ne-fasteners ngaphandle kokuthetha ngokukhuselwa kwe-corrosion. Ngokungathandabuzekiyo esi sesona sigaba sinzima kakhulu kokusingqongileyo. I-Electroplating, ngakumbi i-zinc plating ene-chromate conversion coating (i-classical yellow or blue iridescence), ivelisa amanzi amdaka agcwele isinyithi esinzima, umsi weasidi, kunye nodaka. Imithetho yokusingqongileyo kwi-EU kunye noMntla Melika iye yatyhalela ngakwi-trivalent chromates ngaphezulu kwe-hexavalent, kodwa iindawo zokucocwa kwamanzi amdaka zisantsonkothile kwaye zibiza kakhulu ukusebenza ngokufanelekileyo.

Ndikhe ndandwendwela amaziko akhuphe yonke into yokubeka, ngokusisiseko ndityhala ingxaki ezantsi kumthengisi okhethekileyo. Oko kunokucoca ingxelo yendawo yakho, kodwa ayinciphisi impembelelo yenkqubo ngokubanzi. Abanye, njengabanye abavelisi abadityanisiweyo ngakumbi kwiziseko eziphambili zemveliso zaseTshayina, bazise ngaphakathi ukuze balawule. Ngokomzekelo, inkampani efana I-Sunnian Zitai Festener Fishaner Comment Com., ukusebenza ngaphandle kwesiseko esikhulu esisezantsi eYongnian, kuya kujongana nesi sigqibo ngokuthe ngqo. Ukubekwa kufutshane neendlela ezinkulu zezothutho njengeBeijing-Shenzhen Expressway kubalulekile kulungiselelo lolungiselelo, kodwa kwakhona uzibeke kwindawo enoqwalaselo olwandayo lokusingqongileyo. Ukhetho phakathi kokwakha i-state-of-the-art, isityalo sonyango esivaliweyo ngokuchasene nokuxhomekeka kumntu wesithathu liqhinga lezigidi ezininzi zeedola, ezichaphazela zombini iindleko kunye nokuthotyelwa.

Iindlela ezizezinye ezifana nokucwenga koomatshini (kumalungu amancinane) okanye izinto ezintsha zokwaleka eziphilayo ziyanda. Baziphepha iintsimbi ezinzima. Kodwa beza kunye norhwebo olusebenzayo kwiiyure zovavanyo lwesitshizi setyuwa okanye ii-coefficients zokukhuhlana komsonto. Ukukholisa imoto yemveli okanye umxhasi wokwakha ukuba avume i-coating entsha, eluhlaza kunokuba yinkqubo yemfundo yeminyaka yonke. Inzuzo yokusingqongileyo idla ngokumiswa yimigangatho yobunjineli elondolozayo.

Ulungiselelo kunye neLifecycle Blind Spot

Wonke umntu ulinganisa ukukhutshwa kwesango lomzi-mveliso wakhe. Abambalwa bajonga ngokupheleleyo kwiindleko zekhabhoni zokufumana imathiriyeli ekrwada kunye nokugqitywa Intambo yokuqhuba iimveliso ngaphandle. Loo ndawo ifanelekileyo kufutshane neBeijing-Guangzhou Railway yeyona asethi iphambili kwinkampani efana neZitai, enokuvumela ukutshintshwa kwendlela ukuya kuloliwe ukuze kuthuthwe isambuku. Uthutho lukaloliwe lunokunciphisa ukukhutshwa kwezinto ezikhutshwayo ngama-75% xa kuthelekiswa neelori. Kodwa ifuna ukucwangciswa, umthamo, kunye neziseko zoncedo ezifanelekileyo. Ayisoloko ilukhetho olungagqibekanga lothutho olungxamisekileyo, oluncinci.

Emva koko kukho ukuphela kobomi bemveliso. I-fastener yensimbi kwisakhiwo sensimbi, ngokwethiyori, iphinda isetyenziswe ngokugqibeleleyo kunye nesakhelo. Kodwa ekusebenzeni? Ukuba i-fastener edibeneyo, isambatho sinokungcolisa inyibilika yensimbi. Ukuba ngumsonto wensimbi engenasici, izinto ezidibanisayo ezifana nenickel okanye ichromium ziwenza nzima umjelo wokurisayikilisha. Okufanelekileyo kumbono wezoqoqosho ojikelezayo kuya kuba kuyilo lokuchithwa kunye nemijelo yezinto ezicocekileyo. Oko kukude kwinyani yekhonkrithi ye-anchor efakwe kwikhonkrithi okanye umzimba wemoto otyumkileyo kwi-shredder. Impembelelo yokusingqongileyo iyalityaziswa, ayipheliswa.

Uxinzelelo oluSebenzayo kunye neeNgeniso ezongezelelweyo

Ngoko, ngaba konke kukufa? Hayi ncam. Uxinzelelo luvela kwii-engile ezininzi ngoku. Ayingobalawuli nje; ngabaxumi bezizwe ngezizwe bafuna idatha yekhabhoni yokukhutshwa kwabo koMda we-3. Bafuna ukwazi umkhondo walo lonke icandelo, ukuya kutsho kwiwasha yokugqibela. Oku kunyanzelisa ukucaca phantsi kwekhonkco. Ndibe yinxalenye yophicotho lwababoneleli apho kufuneka unikeze ngamatyala asetyenziswayo, izatifikethi zemathiriyeli, kunye nokubonakaliswa kwenkunkuma. Iyadinwa kodwa iqhuba utshintsho.

Iinzuzo zihlala zinyuka, hayi inguqu. Kumalunga nokuphucula inkqubo onayo. Izinto ezilula: ukufaka ii-variable frequency drives (VFDs) kuzo zonke iimpompo kunye nee-compressor motors ukuhambelana nomthwalo. Ukuthatha ubushushu benkunkuma ukusuka kwiziko ukuya kumanzi okuhlamba ashushu ngaphambili. Ukudibanisa iibhetshi zokucwenga ukwandisa ukusetyenziswa kwetanki kunye nokunciphisa ukutsalwa kweekhemikhali. Ezi zi-unsexy, i-tweaks yokusebenza eyongezayo. Abenzi ukukhutshwa okukhulu kweendaba, kodwa bahambisa inaliti emhlabeni.

Ukujonga iwebhusayithi yomenzi, njengaye I-Zitafasteners.com, unokubona iziqinisekiso ezifana ne-ISO 14001. Leyo yinkqubo-sikhokelo. Kodwa olona vavanyo lokwenyani yinto eyenzekayo ngoLwesibini emva kwemini xa umgca wemveliso usihla, kwaye olona lungiso lukhawulezayo lubandakanya ukudlula inkqubo yokucoca ukuhlangabezana nomhla wokugqibela wokuthumela. Impembelelo yokusingqongileyo ilawulwa ngaloo maxesha oxinzelelo, yinkcubeko emgangathweni, kungekhona nje umgaqo-nkqubo okwi-binder.

Ekugqibeleni, ifuthe lokusingqongileyo of a drill intambo sisixa sewaka lezigqibo ezincinci. Kukukhetho lomthombo wentsimbi, ishedyuli yokugcinwa kwenkqubo yokupholisa, ukusetwa kweqondo lokushisa kwi-oven yokomisa, kunye nendlela yokuthutha ekhethiweyo. Akukho bullet enye yesilivere, ngumsebenzi onzima, oqhubekayo wokwenza isigqibo ngasinye sibe yiqhezu elingonakalisi kangako, ngelixa usenza indawo ebambe umhlaba kunye. Leyo yinyani engcolileyo, engathandekiyo.
