Thaum cov neeg feem coob xav txog ib puag ncig hneev taw ntawm kev tsim khoom, lawv pom cov pa luam yeeb lossis tshuaj lom neeg. Laum xov? Tej zaum tsis yog thawj yam uas los rau hauv siab. Qhov ntawd yog qhov chaw dig muag. Qhov cuam tshuam tsis yog nyob rau hauv cov khoom kawg zaum hauv ib lub thawv; Nws yog woven rau hauv tag nrho cov txheej txheem saw - los ntawm raw steel kauj mus rau txiav cov roj pos huab nyob rau hauv cov huab cua, mus rau cov hlau shavings swept tawm hauv pem teb rhiav. Nws yog ib qho cumulative, feem ntau overlooked lub nra. Tau nyob rau hauv lub Hoobkas hauv pem teb los ntawm Hebei mus rau Essen, zaj dab neeg tiag tiag yog nyob rau hauv cov lus qhia ntxaws, kev sib haum xeeb, thiab cov kev daws teeb meem ib nrab uas tsis tau nkag mus rau hauv cov ntawv ceeb toom kev ruaj ntseg.

Lub hauv paus tsis pom: Raw Material thiab Zog

Nws pib nrog cov hlua hlau. Cov pa roj carbon hneev taw ntawm cov hlau yog ib qho kev koom tes loj tshaj plaws. Yog tias koj siv cov pa hluav taws xob yooj yim (BOF) steel piv rau hluav taws xob arc rauv (EAF) steel los ntawm seem, koj tab tom saib qhov sib txawv ntawm CO2 ntsuas hauv tons ib pawg. Ntau lub hub me me, zoo li pawg hauv Yongnian, keeb kwm cia siab rau hauv cheeb tsam BOF steel rau tus nqi thiab cov khoom siv sib txuas yooj yim. Tus nqi ib puag ncig tau ci los ntawm qhov pib, ib hom kev cuam tshuam ua ntej ua ntej thawj cov xov yog dov.

Tom qab ntawd los lub zog tsav lub tshuab. Txias forging thiab xov dov yog qhov ua tau zoo, tab sis kev txhawb nqa tsis yog. Cov hluav taws kub nyhiab, zinc plating da dej, phosphate txheej kab - lawv yog lub zog hogs. Kuv nco qab txog qhov project nrog ib tus neeg muag khoom nruab nrab uas sim tshuaj xyuas qhov no. Lawv pom tias ntau dua 60% ntawm lawv cov nroj tsuag lub zog kos tau mus rau cov txheej txheem thermal (kev kho cua sov, ziab qhov cub) thiab tsis yog qhov tseeb. Qhov ntawd yog ib tug sawv-up hu. Hloov los ntawm cov pa roj carbon monoxide mus rau cov roj ntuj rau kev sib tsoo yog ib kauj ruam, tab sis qhov kev sib tw tiag tiag yog lub hauv paus load thaum koj khiav 24/7 kom tau raws li lub hom phiaj ntim.

Thiab ntim yog qhov tseem ceeb ntawm no. Cov qauv kev lag luam nyob rau hauv cov qauv ntim siab yog razor-thin margins. Kev nqis peev nyob rau hauv high-efficiency induction cua sov system rau annealing muaj lub sij hawm them rov qab. Thaum koj phau ntawv txiav txim hloov pauv, qhov kev siv peev nyiaj tau raug ncua, dua thiab dua. Kev txhim kho ib puag ncig yog ib txwm nyob rau xyoo tom ntej txoj kev npaj. Kuv tau pom lub voj voog no ua ntej.

Lub Coolant Conundrum thiab khib nyiab ntws

Qhov no yog qhov chaw khw hauv pem teb kev muaj tiag hits. Laum kev khiav hauj lwm, tshwj xeeb tshaj yog tapping thiab xov milling, yuav tsum tau txiav kua. Lub tsev kawm ntawv qub, cov roj ua haujlwm hnyav hnyav tau zoo heev rau cov cuab yeej siv lub neej thiab tiv thaiv galling ntawm stainless hlau threads. Tab sis lawv yog npau suav phem rau kev kho cov khib nyiab. Lawv emulsify, lawv kis tau cov roj tramp thiab nplua hlau particulates. Lub sump hloov mus ua kua zaub lom.

Peb tau sim hloov mus rau semi-synthetic thiab tom qab ze-qhuav MQL (tsawg kawg Lubrication) tshuab ntawm qee cov kab CNC. Txoj kev xav tau zoo tag nrho: txo cov kua dej los ntawm 95%, tshem tawm cov misting, tsim cov chips qhuav uas yooj yim dua rov ua dua. Qhov tseeb? Cov nqi cuab yeej tau nce. Rau qee cov khoom siv high-tensile lossis kab txawv, cov xov zoo tsis zoo ib yam. Peb tau ntsib ntau tus kais tawg thaum pib. Nws yog kev lag luam tawm: qhov pom tseeb ntawm ib puag ncig profile piv rau cov txheej txheem kev ruaj ntseg thiab tus nqi-ib feem. Nws siv ze li ib xyoos ntawm kev sib tw tsis zoo thiab ua haujlwm nrog cov neeg muag khoom los nrhiav kev teeb tsa ruaj khov.

Cov hlau pov tseg nws tus kheej-swarf thiab off-spec qhov chaw-yog lwm yam. Ntxuav, qhuav steel chips yog ib yam khoom. Tab sis oily, ntub chips? Koj tab tom them ib tug neeg coj lawv mus, thiab koj muaj kev pom me ntsis rau qhov chaw uas lawv xaus. Kuv paub txog cov haujlwm uas tau teeb tsa centrifugal nti wringers kom rov qab tau cov roj thiab tsim cov chips qhuav. Nws tau txhim kho kev lag luam ntawm kev rov ua dua tshiab, tig lub chaw nqi rau hauv cov nyiaj tau los me me. Tab sis dua, nws yog kev nqis peev ua ntej uas ntau hla.

Kev kho deg: Qhov tsim nyog phem

Koj tsis tuaj yeem tham txog fasteners yam tsis tau tham txog kev tiv thaiv corrosion. Qhov no yog arguably lub feem ntau environmentally intensive theem. Electroplating, tshwj xeeb tshaj yog zinc plating nrog chromate hloov dua siab tshiab txheej (lub classic daj los yog xiav iridescence), ua rau cov hlau hnyav-laden cov dej khib nyiab, kua qaub fumes, thiab sludge. Cov kev cai ib puag ncig hauv EU thiab North America tau thawb mus rau trivalent chromates tshaj hexavalent, tab sis cov chaw kho dej khib nyiab tseem nyuaj thiab kim kom khiav tau zoo.

Kuv tau mus xyuas cov chaw uas tawm ntawm txhua qhov plating, qhov tseem ceeb thawb qhov teeb meem mus rau tus neeg muag khoom tshwj xeeb. Qhov ntawd tuaj yeem ntxuav koj tus kheej qhov chaw tshaj tawm, tab sis nws tsis txo cov kev cuam tshuam thoob plaws lub cev. Lwm tus, zoo li qee qhov kev sib koom ua ke ntawm cov tuam txhab tsim khoom hauv Suav teb cov chaw tsim khoom loj, tau coj nws hauv tsev rau kev tswj hwm. Piv txwv li, ib lub tuam txhab nyiam HANDAN ZITAI FREWER RAUG UA MOV., Ltd., kev khiav hauj lwm tawm ntawm tus qauv loj hauv paus hauv Yongnian, yuav ntsib qhov kev txiav txim siab ncaj qha. Ua nyob ze rau txoj kev thauj loj xws li Beijing-Shenzhen Expressway yog qhov tseem ceeb rau kev thauj mus los, tab sis kuj muab lawv tso rau hauv ib cheeb tsam nrog kev soj ntsuam ib puag ncig. Kev xaiv ntawm kev tsim kho lub xeev-ntawm-tus-kos duab, kaw-loop kho cog tiv thaiv kev cia siab rau tus neeg thib peb yog ntau lab daus las lub tswv yim, cuam tshuam rau tus nqi thiab kev ua raws cai.

Lwm txoj hauv kev zoo li kev siv tshuab plating (rau qhov me me) lossis cov txheej txheem organic tshiab tau nce hauv av. Lawv zam cov hlau hnyav. Tab sis lawv tuaj nrog kev ua lag luam tawm ntawm cov tshuaj ntsev ntsev cov xuab moos los yog xov kev sib txhuam coefficients. Convincing ib txwm automotive los yog kev tsim kho neeg siv kom pom zoo ib tug tshiab, greener txheej yuav ua tau ib xyoo-ntev txheej txheem. Cov txiaj ntsig ib puag ncig feem ntau raug kaw los ntawm cov qauv kev tswj xyuas engineering.

Logistics thiab Lifecycle Dig Muag Spot

Txhua tus ntsuas lawv lub rooj vag emissions ntawm lub Hoobkas. Tsawg saib holistically ntawm cov nqi carbon ntawm tau txais cov khoom siv raw hauv thiab ua tiav Laum cov khoom tawm. Qhov chaw yooj yim nyob ze ntawm Beijing-Guangzhou Railway yog lub cuab tam tseem ceeb rau lub tuam txhab zoo li Zitai, muaj peev xwm tso cai rau kev hloov ntawm txoj kev mus rau kev tsheb ciav hlau rau kev thauj mus los ntau. Rail freight tuaj yeem txiav emissions los ntawm 75% piv rau cov tsheb thauj khoom. Tab sis nws yuav tsum tau npaj, ntim, thiab txoj cai sab hauv infrastructure. Nws tsis yog ib txwm xaiv qhov kev xaiv rau ceev, me me xa khoom.

Tom qab ntawd muaj qhov khoom kawg ntawm lub neej. Lub steel fastener nyob rau hauv ib tug steel qauv yog, nyob rau hauv txoj kev xav, zoo kawg nkaus recyclable nrog rau cov ncej. Tab sis hauv kev xyaum? Yog tias nws yog plated fastener, txheej txheej tuaj yeem ua rau cov hlau yaj. Yog hais tias nws yog ib tug stainless hlau xov, cov alloying ntsiab zoo li npib tsib xee los yog chromium complicate cov kwj siv dua. Qhov zoo tshaj plaws los ntawm kev pom kev lag luam ncig yuav yog tsim rau kev sib cais thiab cov khoom siv ntshiab. Qhov ntawd yog qhov kev quaj deb ntawm qhov tseeb ntawm lub pob zeb-pob thauj tog rau nkoj los yog lub tsheb lub cev tsoo rau hauv lub shredder. Kev cuam tshuam ib puag ncig yog li ncua, tsis raug tshem tawm.

Cov kev siv zog siab thiab nce ntxiv

Yog li, puas yog txhua yam kev puas tsuaj? Tsis raws nraim. Lub siab yog los ntawm ntau lub ces kaum tam sim no. Nws tsis yog tsuas yog regulators; nws yog cov neeg siv ntau lub teb chaws xav tau cov ntaub ntawv carbon rau lawv qhov Scope 3 emissions. Lawv xav paub cov hneev taw ntawm txhua yam, nqes mus rau lub tshuab ntxhua khaub ncaws kawg. Qhov no yog yuam kom pob tshab hauv cov saw hlau. Kuv tau yog ib feem ntawm cov neeg muag khoom kuaj xyuas qhov uas koj yuav tsum muab cov nqi hluav taws xob, daim ntawv pov thawj khoom siv, thiab cov khoom pov tseg. Nws tedious tab sis nws tsav kev hloov.

Cov txiaj ntsig yog feem ntau incremental, tsis yog revolutionary. Nws yog hais txog optimizing tus txheej txheem koj muaj. Tej yam yooj yim: txhim kho qhov sib txawv zaus tsav (VFDs) ntawm tag nrho cov twj tso kua mis thiab compressor motors kom phim load. Kev ntes cov khib nyiab cua sov los ntawm lub cub tawg mus rau pre-heat ntxuav dej. Consolidating plating batches kom siv lub tank kom zoo tshaj plaws thiab txo cov tshuaj rub tawm. Cov no yog cov tsis zoo nkauj, ua haujlwm tweaks uas ntxiv. Lawv tsis ua rau kev tshaj tawm xov xwm zoo, tab sis lawv txav rab koob rau hauv av.

Saib ntawm cov chaw tsim khoom lub vev xaib, zoo li Zitaifasteners.com, tej zaum koj yuav pom cov ntawv pov thawj zoo li ISO 14001. Qhov ntawd yog lub hauv paus. Tab sis qhov kev sim tiag tiag yog dab tsi tshwm sim rau hnub Tuesday yav tav su thaum cov kab ntau lawm poob qis, thiab kev kho sai tshaj plaws suav nrog kev hla kev pom kom tau raws li lub sijhawm xa khoom xa tuaj. Cov kev cuam tshuam ib puag ncig yog tswj hwm nyob rau hauv cov sij hawm ntawm lub siab, los ntawm kab lis kev cai nyob rau hauv pem teb, tsis yog txoj cai nyob rau hauv lub binder.

Thaum kawg, tus kev cuam tshuam ib puag ncig ntawm ib tug xyaum xov yog ib tug tag nrho ntawm ib txhiab me me kev txiav txim. Nws yog nyob rau hauv kev xaiv ntawm steel qhov chaw, lub sij hawm txij nkawm ntawm lub coolant system, qhov kub thiab txias ntawm lub qhov cub kom qhuav, thiab lub thauj hom xaiv. Tsis muaj ib lub mos txwv nyiaj, tsuas yog qhov nyuaj, ua haujlwm tsis tu ncua ntawm kev txiav txim siab ib feem tsawg dua, thaum tseem ua ib feem uas tuav lub ntiaj teb ua ke. Qhov ntawd yog qhov ntxhov siab, tsis txaus ntseeg qhov tseeb ntawm nws.
