Kev piav qhia ntxaws ntawm cov khoom siv tooj liab thiab cov qauv
Taw qhia: Muaj ntau ntau cov khoom siv tooj liab, suav nrog cov qauv Suav thiab txawv teb chaws. Peb feem ntau yog tham txog cov qauv hauv tsev. Cov qauv hauv tsev rau cov khoom siv tooj liab tau muab faib ua cov qauv kev lag luam, cov qauv hauv zos thiab cov qauv kev lag luam. Lub teb chaws cov qauv hauv cov khoom siv tooj liab tau muab faib ua cov qauv pom zoo thiab cov qauv yuav tsum tau ua. Cov tuam txhab feem ntau siv Suav cov qauv rau cov khoom siv tooj liab. Tau kawg, qee lub tuam txhab tau tsim cov qauv siab dua li cov qauv hauv tebchaws, uas yog cov qauv kev lag luam. Cov qauv ntawm cov khoom siv tooj liab yog qhov tseeb cov qauv tsim los ntawm lub tuam txhab. Txhua lub chaw tsim khoom tuaj yeem tsim cov qauv kev lag luam rau cov khoom siv tooj liab. Kuj tseem muaj ntau lub tshuab rau qib tooj liab. Xws li Asmeskas, Lub Tebchaws, UK, Fabkis thiab Russia thiab lwm yam.
Copper khoom qib hom?
1. Cov khoom siv tooj liab qib: cov khoom siv tooj liab ntshiab nrog cov xim liab-liab. Cov khoom siv tooj liab muaj xws li tooj liab ntshiab, tooj liab tsis muaj oxygen, phosphorus deoxidized tooj liab thiab cov khoom siv tooj liab tshwj xeeb.
2. Brass khoom qib: tooj liab-zinc alloy khoom.
3. Bronze khoom qib: Ameslikas hais txog tooj liab-tin alloy cov ntaub ntawv, thiab tom qab ntawd hais txog tooj liab alloy cov ntaub ntawv uas tsis yog tooj dag thiab cupronickel.
4. Cov khoom siv tooj liab dawb qib: cov khoom siv tooj liab-raws li tooj liab nrog npib tsib xee ua lub ntsiab ntxiv, silvery dawb, thiab xim hlau luster.
Yuav ua li cas qhia Suav cov khoom siv tooj liab? kuv lub teb chaws tus qauv (GB340-76) qhia tias qib naming ntawm cov txheej txheem tooj liab thiab tooj liab alloys yog qhia los ntawm "hom code ntawm tooj liab, lub ntsiab lus tom qab cov cim tshuaj, los yog tus lej sequence". Ntawm lawv, hom code ntawm tooj liab siv thawj tus cim Suav hauv Suav Thawj tsab ntawv ntawm Pinyin, "T" sawv cev rau cov tooj liab dawb, "Q" sawv cev rau tooj liab, thiab "B" sawv cev rau tooj liab dawb.

Yuav ua li cas qhia cov khoom siv tooj liab hauv Asmeskas?
United States UNS tus lej system (ASTME527) qhia tias tooj liab thiab tooj liab alloys siv 5 tus lej raws li cov lej, qhia tias "C + xxxxx (tsib tus lej)", uas, ua cov tooj liab yog "Cl0000?C15999" thiab ua tooj liab alloy yog "C16000?C79999". Cov txheej txheem kev cai no tau sib koom ua ke tshawb fawb thiab tsim los ntawm American Society for Testing and Materials thiab American Society of Mechanical Engineers raws li cov npe ntawm peb tus lej dhau los, thiab tau los ua ib feem ntawm United States Unified Numerical Code System (UNS) rau hlau thiab alloys. .

Yuav ua li cas qhia Japanese tooj liab cov ntaub ntawv qib?
Lub Japanese Industrial Standard (JIS) ua cov tooj liab alloy qib qhia txoj kev yog qhov pib zoo ib yam li US UNS tus lej (ib tus lej tsawg dua). Ntawd yog: C + XXXX (plaub tus lej). Thawj tus lej qhia cov alloy series, sawv cev los ntawm 2 txog 9. Lub ntsiab lus ntawm txhua tus lej yog raws li hauv qab no:
2-- tooj liab-zinc alloy;
3--Copper-zinc-lead alloy;
4--Copper-zinc-tin alloy;
5--Copper-tin series, tooj liab-tin-lead series alloy;
6--Copper-aluminium series, tooj liab-silicon series, tshwj xeeb tooj liab-zinc series alloys;
7--Copper-nickel series, tooj liab-nickel-zinc series alloy;
8, 9 - Tsis tau siv.

Yuav ua li cas qhia German tooj liab cov ntaub ntawv qib?
Nyob rau hauv German Industrial Standards (DIN), muaj ob lub tshuab rau kev qhia cov ntaub ntawv uas tsis yog-ferrous hlau. Ib qho yog lub npe lag luam uas muaj cov cim tshuaj lom neeg, cim cov tsiaj ntawv thiab cov lej Arabic; lwm qhov yog 7-digit code system. Hauv DIN cov ntaub ntawv txheej txheem tam sim no, ob lub tshuab tau siv ua ke thiab teev nyob rau hauv kev sib piv nrog ib leeg.
Ib txoj hauv kev qhia cov qhab nia raws li cov khoom siv tshuaj
Raws li cov kev cai ntawm DIN 1700-1954, cov qib rau kev ua tooj liab thiab tooj liab alloys feem ntau muaj ob ntu:
(1) Kos cov ntawv piav qhia txog kev tsim khoom thiab kev siv ntau yam. Piv txwv li: pom cov tooj liab ntshiab hauv lub rooj;
(2) Qhia ncaj qha rau cov alloy muaj pes tsawg leeg. Piv txwv: Saib lub rooj rau tooj liab alloys.

B Tus lej code sawv cev txoj kev
Raws li cov kev cai ntawm DIN17007-1956, daim ntawv ntawm 7- tus lej code yog raws li nram no:
X·XXXX·XX (ie: pawg naj npawb · pawg naj npawb · tus lej ntxiv)
Ntawm lawv: Pab pawg neeg faib ua 10 pawg loj, tooj liab thiab tooj liab alloys yog pawg 2;
Qeb tus naj npawb - qhia txog cov alloy tshwj xeeb, feem ntau suav nrog raws li cov tshuaj muaj pes tsawg leeg thiab kev npaj ntawm cov khoom;
Tus lej ntxiv - siv los kos cov txheej txheem xws li smelting, pouring, kho cua sov, seb puas muaj kev ua hauj lwm hardening, zoo li, deg mob, thiab lwm yam.
Cov lej tshwj xeeb ntawm German tooj liab thiab tooj liab alloys yog raws li qhia hauv lub rooj.

Yuav ua li cas sawv cev thoob ntiaj teb cov khoom siv tooj liab?
Lub Koom Haum Thoob Ntiaj Teb rau Cov Qauv Txheej Txheem (ISO1190/1-1982) qhia tias cov qib ntawm tooj liab thiab tooj liab alloys tau qhia los ntawm cov tshuaj muaj pes tsawg leeg ntawm cov khoom. Txhua qib yuav tsum tau sau ua ntej nrog "ISO", tab sis thaum nws pom tseeb tias qib ISO yog siv nyob rau hauv cov qauv thoob ntiaj teb lossis cov ntaub ntawv sib txuas lus, "ISO" tuaj yeem raug tshem tawm vim qhov yooj yim. Cov ntsiab lus matrix thiab cov ntsiab lus alloying tseem ceeb yuav tsum siv lub cim thoob ntiaj teb tshuaj lom neeg, ua raws li tsab ntawv qhia txog cov yam ntxwv ntawm cov hlau los yog tus lej qhia cov npe nominal ntawm cov hlau.
Cov txheej txheem ntawm ISO ua tooj liab thiab tooj liab alloy qib yog qhia nyob rau hauv lub rooj.
