Xa usiva 'unyawo lwepleyiti yokuwelda', uninzi lwabantu kwimveliso bacinga malunga nomthamo womthwalo, izinto ezibonakalayo, okanye ukuxhathisa umhlwa. Icala lokusingqongileyo? Ngokuqhelekileyo yingcamango yamva, into yokwenza amaphepha okuthotyelwa. Kodwa emva kokuba ndifumene kwaye ndifake la macandelo kuyo yonke into ukusuka kumanqanaba omsitho wexeshana ukuya kumaqonga ezoshishino asisigxina, ndiyibonile impembelelo iphuma ngeendlela ezingekho kwiphepha. Akukhona nje ngentsimbi oyiweldayo; imalunga nayo yonke into eyichukumisayo, ukusuka kwindawo yokusila ukuya kwindawo yokulahla umsebenzi.

Umjikelo woBomi ofihlakeleyo wePlate Foot

Masiqale ekuqaleni. Elo litye lentsimbi, elihlala licwecwe elilula elidityanisiweyo okanye unyawo olunokulungiswa ngakumbi, alubonakali nje. Ngonyawo oluqhelekileyo lwe-carbon steel, i-bill yendalo esingqongileyo iqala ngokumbiwa kwemigodi kunye nokulungiswa kwentsimbi. Ubukhulu bamandla buyamangalisa. Kodwa nali inqaku elisebenzayo esihlala silikhumbula: i Unyawo lwe-welding uyilo ngokwalo luyalela inkunkuma yezinto. Unyawo oluyilwe kakubi olunezinto ezigqithisileyo 'ukuze ukhuseleke' alubizi nje iindleko ezingaphezulu; kuthetha ukombiwa kwentsimbi ekrwada ngakumbi, amalahle amaninzi atshiswe kwiziko eliqhumayo, kunye ne-CO2 engaphezulu evela kwilitye. Ndikhumbula iprojekthi apho siye satshintsha ukusuka kunyawo olukhulu, oluphoswe ngokwesiko saya kuyilo olulula, oluyilelwe ipleyiti kunye nombhobho ukusuka kumthengisi ofana I-Sunnian Zitai Festener Fishaner Comment Com.. Ukonga ubunzima ngeyunithi nganye yayincinci, mhlawumbi i-15%, kodwa kwiiyunithi ezingama-5000, yayiziitoni zentsimbi ekrwada-kunye nekhabhoni equlethwe yikhabhoni-bekungeyomfuneko ukuba sithumele ngenqanawa kwihlabathi liphela.

Emva koko kukho i-coating. I-Hot-dip galvanizing ngumgangatho wegolide wokukhusela umhlwa, kwaye ngesizathu esihle. Kodwa olo maleko lwezinc luvela kwinkqubo yalo yokuqinisa amandla kwaye ludala imingeni yokucoca amanzi amdaka. Emsebenzini kwindawo engaselunxwemeni, sakha sasebenzisa ipleyiti efakwe ngaphambili yeenyawo, sicinga ukuba silumkile. Intshukumo embi. Ukuwelda kwayitshisa i-zinc ejikeleze imithungo, idala umsi ofuna umoya owongezelelekileyo (amandla angakumbi kwiifeni) kwaye emva koko kwafuneka ukuba sichukumise isitshizi esibandayo se-galvanizing-enye inkonkxa yemichiza. Umlinganiselo opheleleyo wokusingqongileyo woko ‘kulungisa’ mhlawumbi woyike ngaphezu kokusebenzisa ipleyiti engaphathwanga kwaye uyipeyinte ngokufanelekileyo kamva. Isifundo kwisiqingatha-imilinganiselo.

Uthutho lolunye olungenabuqhophololo. Ukufumana indawo enkulu yemveliso efana neSithili saseYongnian e-Handan, esizihlawula ngokwaso njengesiseko senxalenye enkulu yaseTshayina, yenza ingqiqo. Uncedo lokuba kufutshane nomzila kaloliwe omkhulu kunye neendlela, njengendawo ehlala iZitai, kunciphisa amafutha omthwalo. Kodwa yenza imodeli esembindini. Ukuba uyakha eNyakatho Melika kwaye iinyawo zakho zivela eHebei, ukukhutshwa kweenqanawa zaselwandle kuyinxalenye enkulu yempembelelo yobomi bemveliso. Ngamanye amaxesha, unyawo olwenziwe ekuhlaleni olusuka kwivenkile encinci, nakwixabiso eliphezulu leyunithi, linokuba nexabiso eliphantsi lekhabhoni. Lubalo esiqala ukulwenza ngokusesikweni.

IiNyinene ezikwiSiza kunye noLawulo loMsi

Kulapho ithiyori idibana khona negrinder, ngokoqobo. I ifuthe lokusingqongileyo ngexesha lofakelo lukhawuleza kwaye lwasekhaya. Umsi we-welding yi-villain ecacileyo-umxube wee-oxides zetsimbi, ukukhusela igesi ngemveliso, kwaye ngamanye amaxesha i-chromium enehexavalent ukuba usebenza nge-stainless. Sonke sibonile ilifu elimnyama elijikeleze umshiseli. Impembelelo yezempilo kubasebenzi iyona nto iphambili, kodwa loo nto ayipheli nje; Ihlala kwindawo kwaye ihlambe emhlabeni okanye i-drainage ekugqibeleni. Ukusebenzisa iingcingo ze-welding ezisezantsi zinceda, kodwa zibiza kakhulu, kwaye kwimisebenzi yebhajethi eqinile, yinto yokuqala yokufumana ixabiso lexabiso.

Ukusebenza komthombo wamandla kubaluleke ngaphezu kokuba ucinga. Isixhobo esidala esidala, esiqhutywa ngedizili sewelding egubuzelayo ngelixa ucofa iinyawo zeplate kukungasebenzi kakuhle kwendawo. Kwindawo ekude ngaphandle kwamandla egridi, ayinakuphepheka. Kodwa ndiye ndatyhalela iirigi zombane apho kunokwenzeka, ndaze ndajonga neeyunithi zebhetri eziphathwayo kwiiwelds ezincinci. Ukwamkelwa kancinane. Umba omkhulu kukufika kwexesha. A eyilwe kakuhle Unyawo lwe-welding ngokulingana okucacileyo kunye nokujija kufakwe i-welded ngokukhawuleza. Uyilo olungalungiswanga lufuna ukulungiswa, ukusika kwakhona, kunye ne-welding engaphezulu. Elo xesha elongezelelweyo le-arc ngumbane omninzi, intsimbi yokuzalisa ngakumbi, umsi omninzi. Uyilo lokwenziwa kokwenziwa ayisogama lobunjineli nje; yeyokusingqongileyo.

Emva koko kukho izinto ezincedisayo. Ukusika ipleyiti ngokobungakanani kuvelisa inkunkuma. Ngaba usebenzisa i-oxy-fuel, etshisa igesi eninzi kwaye idale isikali se-iron oxide, okanye iplasma, ecocekileyo kodwa efuna umoya ococekileyo, owomileyo? I-solvents yangaphambili yokucoca intsimbi, i-anti-spatter sprays-zonke izinto ezincinci ezisetyenziswayo ezongeza kwimijelo yenkunkuma enobungozi kwiprojekthi enkulu. Siqale ukuqokelela iitoti ze-aerosol ezingenanto ngokwahlukeneyo emva kokuba umphathi wesiza efumene umrhumo omkhulu ngokumangalisayo wokulahla inkunkuma. Yayiyinkathazo, kodwa yasinyanzela ukuba sijonge iindlela zokusebenzisa isambuku endaweni yoko.

Ubomi obude vs. UTshintsho: Inxaki yokuZinza

Eyona nto ibalulekileyo yokusingqongileyo bubomi bemveliso. A unyawo lwepleyiti ethi yonakale kwaye isilele kwiminyaka emihlanu, ibangela ukuba isakhiwo sixhaswe size sitshintshwe, yintlekele xa kuthelekiswa nesinye esihlala amashumi amathathu. Kulapho ukhetho lwezinto eziphathekayo kunye nokukhuselwa kubaluleke kakhulu. Kuyahenda ukusebenzisa intsimbi yekhabhoni ecacileyo kunye nomsebenzi wepeyinti ongabizi kakhulu kwizicelo zangaphakathi, ezomileyo. Kodwa kuthekani ukuba ukusetyenziswa kwesakhiwo kuyatshintsha? Ndibone iinyawo zokugcina iimpahla eziguqulwa zibe yinkxaso yomgca wokucubungula omncinci kunye nomswakama ngamaxesha. Iinyawo zigqwalile kwi-weld seam, indawo yokusilela ekunzima ukuyihlola. I-retrofit-jack up isakhiwo, usike endala, i-weld entsha-yayiphazamisa kakhulu kwaye inzima kakhulu.

Apha kulapho abavelisi abahloniphekileyo abayiqondayo inzululwazi yezinto eziphathekayo bongeza ixabiso. Inkampani esebenza kwisiseko esikhulu soshishino njengeSithili saseYongnian saseHandan asiyondawo yokugcina impahla; babona iindlela zokungaphumeleli kubathengi kuwo wonke amashishini. Banokucebisa ngamabakala ezinto eziphathekayo-njengokusuka kwi-Q235 ukuya kwintsimbi enganyangekiyo yemozulu ngokunyuka kweendleko eziphantsi-okanye kwimigangatho engcono ye-galvanizing. Yabo iwebhsayithi basenokungakhwazi malunga nozinzo, kodwa amaxwebhu edatha yemveliso yawo kubunzima bokugquma kunye neecerts zemathiriyeli zixela elona bali lokwenyani. I-zinc ejiyileyo yokwaleka okanye inkqubo yokwaleka ephindwe kabini inokonyusa impembelelo yokuqala, kodwa ithintela ukuphinda-phindeka kwempembelelo enkulu ekutshintshweni kwangaphambi kwexesha.

Ukulungelelaniswa kwento ngomnye umdlalo wokuqina. Unyawo lwepleyiti elungelelanisiweyo enentonga enemisonto okanye indlela yokutyibilika ivumela ukulinganisa kwiziseko ezingalinganiyo. Oku kunokuthintela uxinzelelo kunye nokudinwa. Kodwa yonke into eshukumayo yindawo enokusilela. Ndibone iinyawo eziguquguqukayo ezinexabiso eliphantsi apho indlela yokutshixa ithinjwa okanye imihlwa igruswe yomelele, ibenza ukuba bangaguquguquki kwaye balunyawo oluzinzileyo oluneziphene. Iindleko zokusingqongileyo apha kubunzima becandelo (umatshini ongaphezulu) ngaphandle kokuqonda inzuzo yokuphila ixesha elide. Ngamanye amaxesha, unyawo olulula, oluqinileyo, olusisigxina kwisiseko esilungiselelwe ngokufanelekileyo lukhetho oluluhlaza.

Ukuphela koBomi: I-Scrap ayisosiphelo

Asifane siyile ukudiliza, kodwa kufuneka. Ekupheleni kobomi, isakhiwo siyachithwa. Kwenzeka ntoni kwiipleyiti ezidityanisiweyo? Ukuba zidityaniswe ngokuthe ngqo kumqadi wokuqala, zihlala zicinywa. Oko kunamandla ngakumbi kunye nomsi. Ukuba zibotshwe ngebhowuti-ezinye ziyivumelayo-zinokuthi zibotshwe, zicocwe, kwaye ziphinde zisetyenziswe okanye zenziwe ngokutsha ngokufanelekileyo. Intsimbi inokuphinda isetyenziswe, kodwa ukugquma kwenza izinto zibe nzima. Insimbi ene-galvanized ingahlaziywa, kodwa i-zinc iyancipha kwisithando somlilo kwaye isoloko ilahleka, okanye ingcolise iileyile zesithando somlilo. Isengcono kunendawo yokulahla inkunkuma, kodwa yilahleko loop.

Kumsebenzi wokuphelisa ukusebenza kumzi-mveliso omdala, sazama ukonga iinyawo. Ezo zazimdaka nje zazilungile. Ezo zinepeyinti engqindilili, esekwe ilothe (ukususela kwixesha lakudala) zaba yingxaki yenkunkuma eyingozi. Iindleko zokulahla ezo nyawo zimbalwa zaziphezulu kunexabiso le-scrap yentsimbi ecocekileyo. Ngoku, siqaphela iinkqubo zokugquma ezisetyenziswa kumaxwebhu ethu akhiweyo, hayi nje ukugcinwa, kodwa ukudilizwa kwixesha elizayo. Kuvakala njengokubhalela umntu inqaku leminyaka engama-50 ukusukela ngoku, kodwa luhlobo lomjikelo wobomi esiludingayo.

Ke, ngaba kukho unyawo lwepleyiti yewelding eluhlaza? Hayi ncma. Kukho uluhlu lweendlela zokukhetha ezingalunganga. Lurhwebo phakathi kwempembelelo yokuqala (izinto eziphathekayo, iingubo, ukuthutha) kunye nokusebenza kwexesha elide (ukuqina, ukulungelelanisa). Olona nyawo lunempembelelo ephantsi yinto ongafanele ukuyisebenzisa-apho uyilo luphelisa imfuno. Olona lulandelayo lufanelekileyo lunyawo oluchazwe ngokufanelekileyo, oluhlala ixesha elide, oluveliswe ngokufanelekileyo olunciphisa inkunkuma kwindawo kwaye luhlala ubomi besakhiwo. Ayisosihloko esimnandi, kodwa lonke uqhagamshelo oludityanisiweyo, kunye neplate yesiseko ethobekileyo, inobunzima obufihliweyo. Ukungayinaki akukwenzi kube khaphukhaphu.

Iishifti ezisebenzayo kunye nemibuzo engaphendulwanga

Ngoko ke yintoni utshintsho emhlabeni? Okokuqala, iinkcukacha. Endaweni yokubiza nje ipleyiti yesiseko edityanisiweyo, i-ASTM A36, ifakwe igalvanized, siqala ukongeza amanqaku malunga nokukhangela izinto (khetha intsimbi ehlaziyiweyo yomxholo), uhlobo lokwaleka (chaza ubuncinci bobukhulu, unqande i-cadmium), kwaye unokukhetha ababoneleli ngeenkqubo zolawulo lokusingqongileyo. Inyanzela incoko. Xa uthumela i-imeyile kumthengisi othanda Handan Zitai Fastener ngale mibuzo, ufunda ngokukhawuleza ukuba ngubani ophezu kwekhonkco labo lokubonelela kwaye ngubani ongekho.

Okwesibini, ukuziqhelanisa kwindawo. Sihlanganisa ukuwelda kuzo zonke iinyawo zepleyiti ukwandisa i-arc-ngexesha kwiinkqubo zokukhupha umsi. Sahlula intsimbi ngokucocekileyo. Izinto ezincinci. Umqobo omkhulu kukubalwa kweendleko. Iindleko zokusingqongileyo zingaphandle-ayikho kwi-P & L yethu, isemhlabeni. Kuze kube yixabiso lekhabhoni okanye imimiselo engqongqo ibethe imveliso enzima, inkuthazo yezemali yokhetho oluluhlaza luhlala lubuthathaka okanye lusekelwe kwiinjongo ze-ESG zenkampani, enokuthi ibe yinto yokuqala yokunciphisa.

Ekugqibeleni, kukho into entsha, kodwa iyacotha. Ngaba zikho iindlela ezisekwe kwibhayoloji, ezingezizo netyhefu ezichasene ne-spatter ezisebenza ngokunjalo? Ngaba singakwazi ukuyila ngakumbi ngebholiti ezinyaweni ukwenzela ulwakhiwo olulula? Ndiyibonile iprototypes yeenyawo ezenziwe ngokuqina okuphezulu, intsimbi ebhityileyo, okanye izinto ezidityanisiweyo zezicelo ezithile, kodwa ukwamkelwa kwilizwe lolwakhiwo olunobuqhetseba ngumkhenkce. I-welding plate foot yimpahla yorhwebo. Impembelelo yayo yokusingqongileyo ilukiwe kwilaphu leshishini elinzima. Ukuyikhulula kuthetha ukujonga inyathelo ngalinye, ukusuka kwindawo yokusila e-Hebei ukuya kwi-scrap yadi e-Rotterdam, kwaye ubuze ukuba kukho indlela engcono kancinane. Amaxesha amaninzi, kukho. Kunqabile nje ukuba yeyona ndlela iphantsi okanye ilula.
