Product Performance

Cam khwb cia tooj dag yog ib tug cam khwb cia hlau raws li Cu-Zn binary alloy, uas muaj ib tug me me crystallization kub lub caij thiab zoo casting kev kawm. Piv rau tin bronze, cam khwb cia tooj dag muaj ntau dua txhua yam khoom. Tsis tas li ntawd, tus nqi qis dua vim tooj dag muaj ntau cov zinc. Cov no yog cov laj thawj vim li cas cam khwb cia tooj dag yog dav siv.

Txawm li cas los xij, piv nrog tin bronze thiab aluminium bronze, cam khwb cia tooj dag muaj qhov tsis zoo corrosion. Vim muaj cov khoom siv tshuaj lom neeg ntawm zinc thiab cov khoom siv hluav taws xob tsawg, tooj dag yog qhov cuam tshuam rau corrosion. Tshwj xeeb tshaj yog nyob rau hauv seawater thiab lwm yam corrosive media nrog electrolytes, interphase tam sim no yog generated ntawm lub tooj liab-nplua nuj theem thiab zinc-nplua nuj theem nyob rau hauv cov qauv tooj dag, uas aggravates lub corrosion ntawm zinc-nplua nuj theem nrog qis electrode peev xwm, uas yog hu ua dezincification. . corrosion.

Cov khoom solubility ntawm zinc hauv tooj dag yog loj heev. Kwv yees li 37 feem pua ​​​​ntawm zinc tuaj yeem yaj hauv tooj liab hauv lub xeev sib npaug ntawm chav tsev kub, thaum txog 30 feem pua ​​​​ntawm zinc tuaj yeem yaj hauv cov khoom tsim tawm tiag tiag. Yog li ntawd, zinc muaj cov tshuaj zoo ntxiv dag zog rau cov tooj liab. Txawm hais tias zoo tib yam tooj dag muaj qee lub zog, hardness thiab zoo casting kev ua tau zoo, nws muaj kev hnav tsis zoo, corrosion kuj, tshwj xeeb tshaj yog corrosion kuj mus ntws seawater, chav thiab inorganic acid. Yog li ntawd, ib qho me me ntawm lwm yam alloying ntsiab lus (feem ntau yog Mn, Al, Fe, Si, Pb, thiab lwm yam) feem ntau yog ntxiv rau cam khwb cia tooj dag los txhim kho nws cov khoom siv kho tshuab, lub cev thiab tshuaj lom neeg, yog li tsim cov tooj dag tshwj xeeb uas tuaj yeem ua tau raws li ntau yam kev ua tau zoo. kev xav tau. , xws li dawb-txiav tooj dag, naval tooj dag, tooj dag muaj zog thiab tuag-cam khwb cia tooj dag.

Lub crystallization kub ntau ntawm tooj dag yog tsawg heev (kwv yees li 30 ~ 40 degree). Thaum cov ntsiab lus zinc nce, cov kua dej kub poob sai, thiab cov ntsiab lus melting txo. Yog li ntawd, tooj dag muaj zoo fluidity thiab cov ntaub ntawv concentrated shrinkage kab noj hniav. , nws tsis yog yooj yim los tsim xoob thiab intracranular cais. Lub melting point ntawm tooj dag yog tsawg, thiab nws muaj ib tug loj npaum li cas ntawm zinc, uas yog ib qho yooj yim mus evaporate. Thaum nws evaporates, nws tuaj yeem tiv thaiv cov hlau los ntawm kev nqus tau thiab tshem tawm cov pa hauv cov kua tooj liab, kom tsis txhob muaj qhov nqus pa thaum lub sij hawm smelting. Yog li ntawd, tooj dag castings feem ntau tsis tsim stomata. Nyob rau tib lub sijhawm, thaum smelting tooj dag, zinc nws tus kheej muaj lub zog deoxidizing, thiab tsis xav tau lwm tus neeg deoxidizing. Yog li ntawd, tooj dag yog yooj yim rau smelt dua lwm yam tooj liab alloys thiab muaj zoo casting zog. Vim muaj kev sib raug zoo ntawm zinc thiab oxygen, oxide ZnO yog yooj yim tsim thaum lub sij hawm smelting txheej txheem ntawm tooj dag. Txawm li cas los xij, nws txawv ntawm Al2O3 thiab yooj yim sib cais rau hauv slag los ntawm cov kua tooj liab. Ntev npaum li kev ntsuas raug coj los tiv thaiv cov oxidation theem nrab ntawm cov hlau, oxidation inclusion defects feem ntau yuav zam tau. . Brass muaj qhov loj shrinkage tus nqi, thiab nws yog ib qho yooj yim los tsim concentrated shrinkage qhov thaum solidification. Yog li ntawd, kev pub noj loj dua tuaj yeem raug teeb tsa raws li lub hauv paus ntsiab lus ntawm kev sib txuas ua ke. Brass muaj cov yam ntxwv ntawm lub plhaub zoo li solidification thiab tsis tshua muaj kev cuam tshuam rau casting txias npaum li cas, yog li nws cov khoom siv tshuab tsis tshua muaj kev cuam tshuam rau cov kev hloov ntawm cov phab ntsa casting.

Hauv casting ntau lawm, binary tooj dag yuav luag tsis siv. Txhawm rau ua kom tau raws li qhov yuav tsum tau ua tshwj xeeb thiab txhim kho cov txheej txheem kev ua tau zoo, ntau cov khoom siv tooj dag casting yog dav siv.

Kev Tswj Xyuas Zoo

1. Tshuaj muaj pes tsawg leeg ntawm Brass Silica Sol Investment Casting

Brass yog Cu-Zn binary alloy nrog zinc ua lub ntsiab alloying, feem ntau hu ua tooj dag lossis tooj dag zoo tib yam. Ordinary tooj dag muaj qee lub zog, hardness thiab zoo casting zog, tab sis tsis hnav tsis kam, corrosion kuj, tshwj xeeb tshaj yog corrosion kuj mus ntws seawater, chav thiab inorganic acid. Ntau cov ntsiab lus alloying feem ntau tuaj yeem raug ntxiv los txhim kho cov khoom siv kho tshuab, lub cev thiab tshuaj lom neeg ntawm tooj dag, ua rau cov tooj dag tshwj xeeb tsim nyog rau ntau qhov chaw, xws li naval tooj dag, dawb-txiav tooj dag, siab zog manganese tooj dag thiab tuag-casting daj tooj liab thiab lwm yam. .

2. Casting txheej txheem

Casting tooj dag alloys muaj qee qhov sib txawv ntawm melting point, fluidity, solidification shrinkage, yaj rhiab heev rau roj, volatility thiab kub cracking nyiam, yog li cov kev siv casting kuj txawv.

Cov txheej txheem casting ntawm casting tooj dag feem ntau suav nrog tuag casting, xuab zeb casting, centrifugal casting, nruam casting thiab peev casting. Cov alloys sib txawv xav tau kev xaiv xaiv.

Cov yam ntxwv ntawm cov cam khwb cia tooj dag yog raws li hauv qab no: zinc hauv cam khwb cia tooj dag yog qhov tseem ceeb cuam tshuam rau cov khoom ntawm cov cam khwb cia tooj dag. Lub vaporization point ntawm zinc yog hais txog 907 degree, thiab lub melting point ntawm cam khwb cia tooj dag yog hais txog 900 degree. , zinc muaj qhov zoo rau evaporate thiab oxidize. Casting tooj dag muaj qhov zoo fluidity, tab sis manganese tooj dag shrinks zoo heev, uas yog nws yooj yim rau shrinkage, txias cracking, deformation thiab lwm yam teeb meem.

Raws li cov yam ntxwv saum toj no, cov kev ntsuas thev naus laus zis hauv qab no yuav tsum tau ua thaum lub sij hawm casting:

1) Xaiv cov xuab zeb cores nrog kev pom zoo kom txo qis kev ntxhov siab thiab tiv thaiv kev tawg thiab deformation.

2) Teem lub riser kom ntxiv dag zog rau kev pub mis.

3) Kev teeb tsa ntawm lub rooj vag system yuav tsum ua kom ntseeg tau tias qhov kev taw qhia ua kom muaj zog, cov qauv ntawm cov slag sau thiab slag thaiv yuav tsum tau teeb tsa, thiab cov kua dej yuav tsum tau ua kom zoo. Lub layout ntawm sab hauv khiav yuav tsum ua kom cov castings txias tusyees.

4) Cov txheej txheem pouring txo qhov kub ntawm cov cam khwb cia hlau kom txo tau cov kua shrinkage thiab tiv thaiv vaporization.

Piv nrog bronze, cov khoom solubility ntawm zinc hauv tooj liab yog loj heev. Nyob rau hauv ib txwm kub sib npaug, txog 37 feem pua ​​​​ntawm zinc tuaj yeem yaj hauv tooj liab, thiab txog 30 feem pua ​​​​ntawm zinc tuaj yeem yaj hauv lub xeev li-cam khwb cia, thaum tin bronze Nyob rau hauv lub xeev as-cam khwb cia, cov khoom solubility loj feem ntawm tin hauv tooj liab. tsuas yog 5 feem pua ​​​​rau 6 feem pua, thiab cov khoom solubility loj feem ntawm txhuas bronze thiab txhuas hauv tooj liab tsuas yog 7 feem pua ​​​​rau 8 feem pua. Yog li ntawd, zinc muaj cov ntsiab lus siab ntawm tooj liab. Cov khoom muaj txiaj ntsig zoo ntxiv dag zog rau cov nyhuv, tib lub sijhawm, cov ntsiab lus alloying feem ntau kuj tuaj yeem yaj hauv tooj dag mus rau qhov sib txawv, ntxiv rau kev txhim kho nws cov khoom siv, yog li ua tooj dag, tshwj xeeb tshaj yog qee cov tooj dag tshwj xeeb, muaj cov yam ntxwv ntawm lub zog siab, tus nqi ntawm zinc. Nws yog qis dua aluminium, tooj liab thiab tin, nplua nuj nyob rau hauv cov peev txheej, thiab cov zinc ntxiv rau hauv tooj dag ntau dua, yog li tus nqi ntawm tooj dag yog qis dua li ntawm tin bronze thiab aluminium bronze. Lub solidification kub ntau yam ntawm tooj dag yog tsawg heev, lub fluidity yog zoo, thiab lub melting yog yooj yim. Vim hais tias tooj dag muaj cov yam ntxwv saum toj no ntawm lub zog siab, tus nqi qis thiab kev ua haujlwm zoo, tooj dag muaj ntau yam, cov khoom siv loj dua thiab siv dav dua li tin bronze thiab aluminium bronze hauv tooj liab alloys. Txawm li cas los xij, qhov hnav tsis kam thiab corrosion kuj ntawm tooj dag tsis zoo li cov tooj liab, tshwj xeeb tshaj yog cov corrosion kuj thiab hnav tsis kam ntawm cov tooj dag zoo tib yam kuj tsawg. Tsuas yog thaum qee cov ntsiab lus alloying tau ntxiv rau ntau yam tshwj xeeb tooj dag, nws hnav tsis kam thiab hnav tsis kam Corrosion kev ua tau zoo thiab txhim khu kev qha.
