Aluminium bronzemuaj cov khoom pov thawj muaj zog nqus, yooj yim oxidation slag, loj solidification shrinkage, tsis zoo thermal conductivity, thiab tsis zoo casting kev ua tau zoo. Ua ntej casting, tin bronze manufacturers siv ib tug sib tov ntawm ib co alkali ntiaj teb hlau tebchaw, xws li Na₃AlF₆ thiab NaF, raws li ib tug slagging tus neeg sawv cev los purify kua tooj liab. Nws ua tau zoo los txhim kho cov qauv crystalline ntawm cov kua hlau ntshiab thiab ingot.
Qhov ntsuas kub ntawm aluminium bronze feem ntau yog 1120 ~ 1180 ℃, thiab qhov ntsuas kub ntawm qhov loj me me feem ntau qis dua. Thaum txhuas bronze puag ncig ingot yog cam khwb cia, cov hlau ua kua theem nyob rau hauv pwm tuaj yeem cam khwb cia rau hauv ib qho qhib ntws yam tsis muaj kev tiv thaiv.
Lub yaj nkag mus rau hauv pwm los ntawm ib lub qhov nyob rau hauv qab ntawm lub funnel. Kev tsim ntawm funnel aperture yuav tsum ua tau raws li ob qho xwm txheej tib lub sijhawm: ib qho yog los xyuas kom meej qhov txaus txaus sib piv rau qhov nrawm nrawm; Qhov thib ob, xyuas kom meej tias lub funnel yeej ib txwm tswj tau ib theem ntawm cov kua, kom cov kua deg scum tsis tuaj yeem ntws mus rau hauv pwm los ntawm lub qhov funnel. Aluminium-bronze ingot yog nquag rau porosity thiab concentrated shrinkage. Nws yog ib qho tsim nyog yuav tsum tau ua tib zoo sau thaum kawg ntawm pouring kom tsis txhob muaj concentrated shrinkage ntawm ingot.
Aluminium-bronze hlau nrog dabtsi yog khoov tej zaum yuav muaj ib co nro instability thiab fluctuation. Yog tias muaj qee qhov kev cuam tshuam rau ntawm qhov chaw, qhov saum npoo ntawm cov hlau tooj liab tau raug puas tsuaj, uas yuav tshwm sim hauv cov txheej txheem ntawm kev kos duab, qhia tias qhov zoo ntawm cov hlau tsis zoo. Yog tias cov hlau tooj liab uas tsim muaj qhov xwm txheej no, peb yuav tsum tau xyuam xim xyuas seb peb cov pwm puas tau hnav, thiab seb lub log tsheb tsis hloov tau ntev, uas yuav ua rau muaj teeb meem flash.
Yog tias muaj qee qhov ploj lawm ntawm qhov chaw ntawm aluminium bronze hlau, qhov pom kev ua tiav tsis zoo. Qhov tshwm sim no yog hu ua cov plaub hau, uas kuj yog tshwm sim los ntawm kev hnav thiab tsim kua muag, thiab muaj qee qhov khawb thiab lwm yam teeb meem, uas qhia tau hais tias qhov zoo ntawm tooj liab hlau tsis zoo heev. Los ntawm qhov zoo li tuaj yeem pom qhov zoo ntawm tooj liab hlau, yog li peb yuav tsum qhib peb lub qhov muag thaum muas tooj liab hlau, tsis txhob tsis meej pem los ntawm cov khoom tsis zoo.
