Cov Cuab Yeej Ua Yeeb Yam Ua Yeeb Yaj Kiab Ntawm Tooj Dag

Cov yam ntxwv ntawm kev ua lub ntsej muag tooj dag yog: zinc hauv cov tooj dag yog qhov ua rau lub zog ua haujlwm ntawm kev ua cov tooj dag. Lub ntsiab lus vaporization ntawm zinc yog li 907 ℃, thiab lub ntsiab lus melting ntawm cam khwb cia tooj dag yog li 900 ℃. , Zinc muaj cov cwj pwm zoo ua kom xau thiab oxidize. Casting tooj dag tau zoo fluidity, tab sis manganese tooj dag shrinks zoo heev, thiab nws yog nquag shrinkage, txias tawg thiab deformation.
Txhawm rau pom ntawm cov yam ntxwv saum toj no, cov txheej txheem kev coj ua hauv qab no yuav tsum tau ua thaum pov:

•  - Xaiv cov xuab zeb tseem ceeb nrog txoj cai zoo kom txo kev ntxhov siab thiab ua kom tsis txhob tawg thiab ua kom tawg.
•  - Teeb tsa tus riser kom ntxiv dag zog rau kev pub mis.
•  - Lub gating system yuav tsum tau teeb tsa los xyuas kom meej qhov tseeb ntawm cov kev taw qhia solidification, cov sau slag thiab slag khaws cov qauv yuav tsum tau teeb tsa, thiab cov kua ntws yuav tsum tau sau kom zoo. Lub rhawv khiav haujlwm sab hauv yuav tsum ua kom cov tub ua kom txias.
•  - Cov txheej txheem pouring minimizes pouring kub ntawm cam khwb cia tooj dag kom txo qis ntsws ua kua thiab tiv thaiv vaporization.

Cov txheej txheem ntawm kev ua los ntawm kev siv tooj dag feem ntau yog kev tuag casting, xuab zeb casting, centrifugal casting, nruam casting thiab peev casting. Alloys sib txawv yuav tsum tau xaiv hauv qhov tseeb.

Casting tooj dag yog casting hlau raws li Cu-Zn binary alloy. Nws cov crystallization kub sib txawv me me thiab nws cov yeeb yam kev ua tau zoo dua. Piv nrog tin tooj dag, cam khwb cia tooj dag muaj ntau dua cov cuab yeej. Tsis tas li ntawd, vim hais tias tooj dag muaj qhov ntau ntawm zinc, tus nqi yuav qis dua. Nov yog cov laj thawj uas vim li cas txhav txhav yog siv dav.

Txawm li cas los xij, piv nrog tin bronze thiab aluminium bronze, cam khwb cia tooj dag muaj qhov tsis zoo corrosion. Vim tias cov tshuaj lom neeg nquag ua haujlwm ntawm zinc thiab qis dua electrode muaj peev xwm, tooj dag yog qhov ntau yuav xeb. Tshwj xeeb tshaj yog nyob rau hauv hiav txwv dej thiab lwm yam xov xwm corrosive nrog electrolyte, qhov tam sim no interphase yog tsim nyob nruab nrab ntawm cov tooj liab-theem theem thiab zinc-nplua nuj theem nyob hauv cov tooj dag tus qauv, uas ua rau muaj qhov xeb ntawm zinc-nplua nuj theem nrog qis electrode muaj peev xwm, uas yog hu ua dezincification corrosion.

Cov khoom solubility ntawm zinc hauv tooj dag yog qhov loj heev. Raws li qhov kub thiab txias tsis sib luag, kwv yees li 37% ntawm zinc yuav yaj nyob rau hauv tooj liab, thaum nyob hauv kev tsim khoom tiag tiag, kwv yees li 30% ntawm zinc yuav yaj tau nyob hauv xeev li. Yog li no, zinc muaj cov tshuaj zoo zoo ntxiv rau hauv cov tooj liab. Txawm hais tias tooj dag zoo li qub muaj qee yam muaj zog, ua haujlwm nyuaj thiab zoo casting txheej txheem kev ua tau zoo, nws muaj qhov tsis zoo hnav tsis kam thiab corrosion tsis kam, tshwj xeeb tshaj yog tiv thaiv ntws dej hiav txwv, chav thiab inorganic acid.
