kais dej khoom! Dab tsi koj xav ntawm tooj dag thiab steel hlau yog qhov ua tau zoo heev

Kais dej muaj peb ntu: lub cev tseem ceeb, lub pob valve thiab lub ntsej muag. Cov lus ntawm tib neeg pob tw, lub siab thiab tawv nqaij.

Hais txog tus kais dej yuav khoom, tsis muaj teeb meem dab tsi los ntawm lub kaum ntse ntse kom pom zoo, txhua yam nyob ib puag ncig cov khoom siv teeb meem.

Tshooj lus no yuav hais txog hom kev ua kais dej lub ntsiab thiab lawv qhov zoo thiab qhov tsis zoo.

Kais dej cov khoom siv feem ntau yog tooj liab, stainless hlau, zinc hlau, thiab lwm yam.

1 、 Tooj liab

Tus kais tooj liab yog qhov siv dav tshaj plaws thiab cov khoom ua kom zoo nkauj hauv khw. Copper alloy yog corrosion-resistant thiab cov khoom ua los ntawm nws yog ntau ruaj. Tooj liab ion muaj cov dej num ua haujlwm tua kab mob thiab tuaj yeem ua kom muaj kev noj qab haus huv ntawm cov dej.

1. Txhua tus tooj liab thiab ntshiab tooj liab

Ua ntej tshaj plaws, peb yuav tsum txhais lub tswvyim: txhua tooj copper tooj liab.

Cov tooj liab ntshiab yog hais txog cov tooj liab nrog qhov dawb huv tshaj li 99.5% tom qab kev txhim kho cov cuab yeej. Tab sis cov tooj liab ntshiab yog mos thiab tsis yooj yim txiav, yog li nws tsis haum rau ua kais dej.

Feem ntau ntawm cov khoom siv hauv paus ntawm tooj liab cov khoom lag luam ntawm cov lag luam yog tooj liab zinc alloy.

Vim tias nws cov cuab yeej zoo, thermoplastic zoo, tshuab tau zoo, yooj yim ua kom tawg thiab vuam, tiv thaiv corrosion thiab lwm yam zoo, nws tau siv dav hauv cov khoom lag luam.

Tag nrho cov khoom lag luam yog ua los ntawm tooj liab cov khoom siv tooj, uas tuaj yeem raug hu" txhua tus tooj liab kais dej" Qee qhov lag luam txhawm rau nyiam cov neeg siv khoom, ua si" ntshiab tooj liab kais dej" yog qhov tsis muaj txuj ci, thiab raug xav tias tsis muaj tseeb ntawm kev tshaj tawm.

Qhov tseeb, txhua tus tooj liab thiab ntshiab tooj liab tau yog ob lub tswv yim sib txawv. Thaum muas cov kais dej khoom, cov neeg siv khoom yuav tsum paub txog" txhua txhua tooj liab" thiab xyuam xim rau kev tshuaj ntsuam.

2. Lub teb chaws tus qauv tooj liab thiab tsis tooj liab

Cov ntshiab tooj liab tuaj yeem' t ua kais dej ib leeg, yog li lwm cov alloys yuav tsum tau ntxiv txhawm rau txhim kho kev ua haujlwm.

Raws li cov ntsiab lus ntawm tooj liab hauv qhov sib xyaw, nws tseem tuaj yeem faib ua H59 tooj liab, H62 tooj liab, H65 tooj liab thiab lwm yam.

Ntawm lawv, H59 tooj liab yog cov khoom tseem ceeb ntawm tooj liab kais dej, uas yog HPb59-1 tooj liab. Thawj ntawv" H" ntawm cov hom qhia tias tooj daj, thiab ob tus lej kawg qhia txog cov ntsiab lus nruab nrab ntawm tooj dag. 59 tooj liab txhais tau hais tias tooj liab cov ntsiab lus ≥ 59%, thiab - 1 txhais tau tias cov ntsiab lus txhuas< 1%.="" vim="" tias="" nws="" tau="" raws="" li="" qhov="" yuav="" tsum="" tau="" ua="" ntawm="" lub="" teb="" chaws="" tus="" qauv,="" h59="" tooj="" liab="" tseem="" hu="" ua="" lub="" teb="" chaws="" tus="" qauv="" tooj="">

Kev raws cai, tseem muaj" tooj liab tsis yog", uas yog, tooj liab tsis tau raws li cov kev xav tau ntawm lub teb chaws tus qauv. Ntau cov kais dej nyob qis siv cov tooj liab tsis zoo. Cov tooj liab tsis zoo no yuav tso cov hlau ntau thiab lwm yam khoom uas tsis zoo, siv ntev ntev yog qhov tsis zoo rau tib neeg kev noj qab haus huv!

3. Cov ntshiab ua tooj liab, cov khoom siv tooj liab tsawg thiab tsis muaj txhuas ua

Peb txhua tus paub tias cov khoom siv hlau hnyav yog qhov tsim kev puas tsuaj rau lub cev, yog li vim li cas thiaj li yuav tsum tau ntxiv cov hlau thaum tooj dag rau lub taub kais dej?

Qhov no yog vim hais tias ntxiv ntawm cov txhuas yuav zoo heev txhim kho tshuab kev lag luam ntawm tooj dag castings. Hmoov txhuas yog insoluble hauv tooj liab zinc alloy, tab sis nws tuaj yeem ua si tau zoo tshaj plaws muaj txiaj ntsig. Yog tias tsis ntxiv cov hlau lead, nws yuav nyuaj rau kais dej

Qee tus neeg sib tham txog cov hlau lead txhuas thiab xaiv cov kais dej txhuas. Qhov tseeb, cov txhuas tswj cov ntsiab lus ntawm cov kav hlau qhib tau paub tab heev.

Thaum muas khoom, peb feem ntau pom" ntshiab tooj liab, tooj liab tsis tshua muaj tooj liab, txhuas tsis muaj tooj liab" thiab lwm cov qauv sib txawv, uas yog kev hais tawm ntawm cov kav dej txhuas tsawg.

GG quot; Ua tooj dawb" tsis yog xoom cov ntsiab lus, tab sis cov ntsiab lus ntawm txhuas yog tsawg dua 0.3%." tus nqi qis tooj liab" thawj zaug tau thov los ntawm Tebchaws Meskas, thiab tus qauv yog 0.25% cov ntsiab lus txhuas. Lub ntsiab lus ntawm" huv si tooj liab tooj" thiab" tus nqi qis tooj liab" yog txawv xwb.

25% - 0.3%, cov ntsiab lus txhuas tau tswj tau tsawg heev, kom muaj kev nyab xeeb thiab kev nyab xeeb ntawm dej.

2 、 Stainless hlau

Lub tshuab ua tawv tawv thiab tawv ntawm cov hlau kais dej yog qhov zoo dua li tooj liab, uas yog qhov ruaj khov. Tsis muaj xeb, tsis muaj hmoov txhuas, kev noj qab haus huv thiab kev tiv thaiv ib puag ncig.

Stainless hlau yog li uas zoo li ob lub taum mog, 300 tawm series thiab 400 series. Cov tswv yim txawj tshaj lij yog tias ferrite, martensite thiab austenite feem ntau muab faib raws cov qauv siv lead ua. Cov hom nquag yog 430, 201, 304 thiab 316, uas yuav luag zoo tib yam hauv qhov zoo li, tab sis qhov tseeb qhov ua tau thiab tus nqi yog txawv heev. 200 hom hlau stainless tau muab faib ua plaub hom.

430: cov ntsiab lus yog hais txog hlau + 12 % chromium, uas yog tus nqi qis tshaj thiab qhov tsis zoo tshaj plaws xeb ntawm plaub cov ntaub ntawv. Cov neeg koom tes ua zoo yuav pom tias txheej txheej sab nraud ntawm hauv qab ntawm lub lauj kaub stainless hlau yog tsim los ntawm cov hom steel, yog li lub sijhawm ntev, nws yuav tsim cov av uas nyuaj rau tshem tawm.

201: tseem hu ua siab manganese steel, siab manganese, yooj yim xeb; tsawg npib tsib xee, kev ua haujlwm tsis xeb tsawg dua li 304. Ntawm kev ua lag luam, txhawm rau txuag nqi, qee qhov lag luam txhaum cai dag cov neeg siv los ntawm kev siv 201 li 304.

304: tseem hu ua 18/8 stainless hlau, nws cov ntsiab lus yog hais txog hlau + 18 % chromium + 8 % npib tsib xee. Nws cov khoom coj los tiv thaiv xeb thiab tiv thaiv xeb yog zoo dua 201 thiab 430. Nws yog cov khoom siv dav hlau feem ntau tam sim no.

316: tseem hu ua 18/10 stainless hlau, cov ntsiab lus yog hais txog hlau + 18 % chromium + 10 % npib tsib xee, tus nqi yog qhov siab tshaj plaws ntawm txhua yam khoom siv, thiab kev tiv thaiv xeb thiab tiv thaiv xeb ua tau zoo tshaj plaws. 316 feem ntau yog siv rau hauv qee cov cuab yeej siv siab, xws li khoom siv hauv tshuab aerospace, khoom noj khoom haus tshuab, khoom noj zoo siab hauv chav ua noj thiab lwm cov teb.

Cov teb chaws tsim hauv Tebchaws Europe thiab Tebchaws Asmeskas muaj cov kev cai nruj me ntsis ntawm kev ua zaub mov noj tog hlau stainless. Nws tau sau tseg tias stainless hlau siv nyob rau hauv kev sib cuag ncaj qha nrog zaub mov muaj tsawg kawg 16% chromium, uas tuaj yeem hais tau tias yog kev siv hais tau zoo heev. Hauv peb lub neej txhua hnub, peb cov dej ua noj thiab dej haus tau los ntawm tus kais. Rau kev nyab xeeb thiab kev noj qab haus huv, cov hlau kais hlau yuav tsum tau tsawg kawg yog ua los ntawm 304 khoom.

3 、 Zinc alloy

Zinc alloy kais dej muaj qhov zoo ntawm tus nqi qis, yooj yim rau xeb, cov ntsiab lus ntawm cov hlau hnyav thiab lub neej ua haujlwm luv.

Yog li ntawd, nws tsis pom zoo kom yuav cov khoom siv zinc alloy.

Nws raug nquahu kom yuav Brass thiab stainless hlau kais dej. Cov kais dej zoo steel hlau kim dua. Yog tias koj them nyiaj ntau dua rau cov nqi ua haujlwm, tooj liab kais dej yeej yog qhov kev xaiv zoo.
