Nrog rau kev nce siab ntxiv ntawm cov peev txheej thiab ib puag ncig hauv peb lub tebchaws, kev ua kom muaj kev tiv thaiv kev ua phooj ywg zoo li kev tsim txom ntawm 20% Hauv Suav teb,chaw ua casumingUa lub luag haujlwm tseem ceeb heev hauv kev tsim khoom machinery chaw kev lag luam, nrog Casting ntau lawm qeb thawj hauv lub ntiaj teb rau 60 xyoo sib law liag. Muaj ntau tshaj 27000 Casting cov lag luam, nyob rau hauv ob peb cov khoom lag luam loj, thiab cov khoom siv ntau lawm, thiab ib puag ncig cov teeb meem uas tsis tau muab tso rau hauv lub sijhawm ua haujlwm.
Lub hauv paus kev lag luam hauv peb lub teb chaws tab tom ntsib kev cov nyom ntawm ib puag ncig. Raws li cov lus tshaj tawm, 80% rau 95% ntawm Tuam Tshojchaw ua casumingCov teeb meem tsuas yog siv phau ntawv moulding, thiab tsawg dua 5% ntawm tag nrho cov naj npawb ntawm cov hluav taws kub tawg tau nruab nrog cov chaw tiv thaiv ib puag ncig. Ntau tshaj 80% ntawm cov khoom lag luam ua pov hwm muaj cov kev ua haujlwm ntawm thaj chaw ib puag ncig, kev ua haujlwm tsis zoo, thiab cov txheej txheem ntau lawm. Los ntawm qhov kev pom ntawm cov qauv ntawm kev lag luam meting, kev lag luam muaj ob qho kev cob qhia ntau lawm cog qoob loo lossis cov kws tshaj lij kev nruam cov nroj tsuag thiab ntau tus lej ntawm cov chaw ntoo. Nyob rau hauv cov nqe lus ntawm cov qib kev tsim khoom thiab cov nplai, muaj cov txheej txheem loj nrog cov tshuab hluav taws xob siab, thev naus laus zis, thiab txhua xyoo cov zis txhua xyoo ntawm tons ntawmcov khoom siv, nrog rau cov khoom siv me me nrog cov khoom siv yooj yim, kev ua haujlwm qub, thiab txhua xyoo tso zis tawm ntawm ib puas lub tons ntawm cov duab ua ke. Nyob rau hauv xyoo tsis ntev los no, vim muaj kev cuam tshuam ntawm lub zog, ib puag ncig, thiab lawv tau muab cov ntsiab lus tseem ceeb nrog cov ntsiab lus thev naus laus zis thiab cov txiaj ntsig siab los tsim cov tebchaws. Tam sim no, lub nrawm ntawm kev lag luam thoob ntiaj teb muaj kev lag luam hauv ntiaj teb no muab ob txoj hauv kev thiab cov nyom rau kev txhim kho ntawm Tuam Tshoj lub ntsej muag Kev Lag Luam. Qhov kev thov rau Suav cov casting hauv ob qho kev lag luam thoob ntiaj teb thiab hauv tsev yog qhia kev txhim kho kev loj hlob.
Casting Khoom Siv, Casting Xuab Zeb Ua MOULDING
Casting Khoom Siv,Casting Xuab Zeb Ua MOULDING
Raws li cov thev naus laus zis tam sim no thiab cov teeb meem tseem ceeb hauv Suav teb, tsab xov xwm no tau tshawb fawb "tus phooj ywg ib puag ncig casting" los ntawm cov hauv qab no:
1.Qhov kev txhim kho cov qauv kev tsim khoom ntsuab rau cov cuab yeej siv ntsuab, cov cuab yeej siv thev naus laus zis, thiab cov txheej txheem ua lag luam, thiab ua kom zoo nkauj ib puag ncig cov khoom siv ntawm cov chaw cas los xij uas yog kev siv tshuab lossis cov khoom siv hluav taws xob zoo nkauj (cov khoom siv ntsuab) ④ Ua kom tau txais txiaj ntsig zoo, nrawm thiab tswj cov cuab yeej siv ua kom zoo nkauj, txhim kho casting cov khoom pov tseg, thiab ua tiav "ntsuab thiab tus phooj ywg ib puag ncig casting"; Siv tau thiab siv tau thaum xaus ntawm kev kho yeeb nkab kho tshuab kom txo tau cov paug ntawm ib puag ncig. Ntxiv nrog rau cov kev xav tau cov kev xav tau rau cov haujlwm saum toj no, yog li ntawd, cov neeg lag luam zoo tshaj plaws uas tuaj yeem ua tiav cov tshuaj ib puag ncig hauv tebchaws.
2. Pib los ntawm ntau yam kev xws li CAST thev naus laus zis, pwm cov ntaub ntawv, thiab cov khoom siv
Cov kev tiv thaiv tam sim no ntawm kev tiv thaiv ib puag ncig hauv Suav teb cov kev lag luam muaj kev txhawj xeeb. Efforts can be made to promote environmental protection in the foundry industry from various aspects such as casting technology, molding materials, and casting equipment: ① Casting technology and molding materials: Sand casting is the main method of casting technology, accounting for 80% to 90% of the entire casting production. Hauv kev sib xyaw ua ke, cov plua plav muaj kuab paug, huab cua ua qias tuaj, thiab cov pa phem tshwm sim los ntawm cov ntaub ntawv molding ntawm cov xuab zeb casting yog qhov loj tshaj. Therefore, in order to achieve green and clean production in sand casting, green inorganic binders should be used as much as possible, and the amount of binders added should be reduced as much as possible (preferably without binders). Qhov no muaj txiaj ntsig zoo heev rau kev daws cov teeb meem ntawm kev rov ua dua qub xuab zeb thiab yuav muaj kev txo qis ntawm cov ib puag ncig. Among the various methods of sand casting currently involved, the lost foam casting and V-method casting using adhesive free dry sand molding, as well as the water glass sand casting with adhesive, are the most likely to achieve “green and environmentally friendly casting” production processes. The adhesive free lost foam casting is known as the “new casting technology of the 21st century” and “green engineering in casting” Casting equipment: Currently, most of China's cast iron parts are melted and produced using blast furnaces, which use clean and long-life refractory materials, high-efficiency hot air continuous blast furnaces, and iron liquid enclosed transportation, pouring, and mold treatment technologies to reduce the amount of metal oxidation and slag tiam; Adopting the recommended measures of the International Council for Casting Environment Control for pre purification treatment of furnace materials can reduce the emission of dust during the smelting process; Kev siv ntawm cov dej-txias granulation slag technology tuaj yeem ua rau slag tau cov khoom siv tsev ua tau zoo; Nkag siab siv cov pa roj tawm ntawm cov pa hluav taws tawg. In addition, in casting production, process equipment that generates dust and noise, such as transportation, screening, cleaning, and sand dropping equipment, can be improved from the product structure to reduce or eliminate dust.
3. Kev tsim cov thev naus laus zis tshiab rau cov peev txheej siv cov pa roj pov tseg thiab ua kom muaj lub hom phiaj siv hluav taws xob tau dhau los ntawm cov neeg ua haujlwm nrawm hauv ntau lub tebchaws. Yog li ntawd, thaum Tuam Tshoj cov neeg lag luam khoom lag luam tsim tsim lossis nqa tawm cov kev hloov pauv thev naus laus zis, lawv yuav tsum rov ua haujlwm ntxiv cov khib nyiab. Qhov no tuaj yeem ua tau los ntawm cov hauv qab no: ① Thaum cov phiaj xwm kev tiv thaiv kev tiv thaiv ib puag ncig, thiab nws tau pom zoo tias kev tiv thaiv ib puag ncig kev lag luam rau ib puag ntej 15% ntawm tag nrho cov peev txheej; ② Tau txais cov cuab yeej ua kom tau cov cuab yeej yooj yim uas yog mechanized, siv tshuab, thiab cov hom phiaj kev tiv thaiv ua tiav; ③ Siv cov txheej txheem huv cov txheej txheem los txhim kho kev ua haujlwm zoo; ④ Tsim cov thev naus laus zis tshiab rau cov peev txheej siv cov khoom pov tseg los ntawm kev xa mus rau cov khib nyiab pov tseg; ⑤ Ua raws li cov ntsiab cai txo, rov siv dua, thiab rov ua dua tshiab hauv kev lag luam ncig.
Ntsuab thiab ib puag ncig ua phooj ywg casting "yog qhov ua kom pom kev txhim kho kev txhim kho kev lag luam social kev lag luam hauv kev tsim khoom lag luam. Pib ntawm lub peev xwm ntau lawm, qib thev naus laus zis, cov khoom siv roj av, thiab cov qauv kev tsim kho ntawm cov khoom lag luam hauv ib puag ncig Ntawm cov kev sib txawv ntau lawm hauv cov txheej txheem ntau lawm yog tsim los ua cov hom phiaj ntawm kev tsim kho tshiab, nthuav dav, thiab kev hloov pauv hloov pauv ntawm Tuam Tshoj cov chaw tsim khoom lag luam. Kev coj cwj pwm ntawm kev tiv thaiv ntau lawm, thiab kev tiv thaiv ib puag ncig yog ua kom tiav txoj kev lag luam thev naus laus zis ntawm kev lag luam hauv tebchaws.
