Basic smelting txheej txheem ntawm txhuas bronze ZCuAl10Fe3
Npaj ua hauj lwm ua ntej smelting
Kev npaj cov khoom siv raw thiab cov khoom siv rov ua dua:
Cov ntaub ntawv raw muaj xws li electrolytic tooj liab, metallic aluminium, hlau, manganese, npib tsib xee, thiab lwm yam. Qhov saum npoo yuav tsum huv thiab tsis muaj roj stains.
Cov khoom siv rov ua dua tshiab yog cov sprues thiab cov khoom seem, uas yuav tsum tau ntxuav cov roj stains.
Kev npaj ntawm master alloy:
10-3 master alloy (Al-Fe alloy) yog ntxiv ntawm qhov sib piv ntawm 10: 3, coj mus rau hauv tus account qhov tseeb qhov cub zoo tom qab hlawv poob.
Flux xaiv:
Kev xaiv cov slag tshem tawm cov neeg ua haujlwm thiab cov tshuaj ua kom zoo muaj qhov cuam tshuam tseem ceeb ntawm cov khoom siv kho tshuab thiab muaj pes tsawg leeg ntawm cov hlau.
Cov khoom siv melting:
Kev tshuaj xyuas thiab kev npaj cov roj furnaces thiab cov cuab yeej, suav nrog cov xwm txheej ntawm crucible, ntxuav cov roj nozzles, preheating ntawm cov cuab yeej melting, thiab lwm yam.
Cov khoom siv pouring:
Kev tshuaj xyuas thiab kev saib xyuas ntawm cov tshuab centrifugal casting kom paub meej tias cov khoom siv hluav taws xob, cov plhaub tiv thaiv, pwm fixtures, thiab lwm yam.
Kev npaj cov ladles rau masonry siv cov ntaub ntawv tshwj xeeb thiab proportions.
Smelting txheej txheem
Chemical composition range:
Aluminium (Al) 8.5 txog 11%, hlau (Fe) 2.
Smelting cov kauj ruam:
Tshawb xyuas cov roj cub hluav taws xob thiab ua kom sov rau 200-300 degree .
Ntxiv Al-Fe master alloy thiab electrolytic tooj liab thiab yaj kom txog thaum cov electrolytic tooj liab pom tseeb.
Tom qab melting, do kom zoo thiab khaws qhov kub ntawm 1250 degree ~ 1300 degree.
Ntxiv slag tshem tawm kom tshem tawm slag, ua kom sov thiab so rau 10 feeb.
Nqa cov qauv rau kev txheeb xyuas cov khoom.
Thaum pouring castings, them sai sai rau lub pouring kub rau castings nrog txawv phab ntsa thicknesses.
Pouring thiab txias:
nruj me ntsis tswj qhov hnyav ntawm molten tooj liab kom tsis txhob pov tseg.
Tom qab centrifugal pouring, cia lub casting txias ib txwm mus rau tsaus liab (500 degree -600 degree) ua ntej quenching nws.
Cov kev ceev faj
Aluminium bronze alloy yooj yim ua ke nrog oxygen los tsim oxides thaum lub sij hawm smelting txheej txheem, yog li stirring yuav tsum tau txo kom tsis txhob puas cov oxide zaj duab xis ntawm cov kua nto.
Qhov kub thiab tshuaj lom neeg muaj pes tsawg leeg yuav tsum nruj me ntsis tswj thaum lub sij hawm smelting txheej txheem los xyuas kom meej cov kev ua tau zoo ntawm cov alloy.
Cov kauj ruam pouring thiab txias yog qhov tseem ceeb rau kev ua tau zoo ntawm qhov kawg casting thiab yuav tsum tau ua raws li qhov ntsuas kub thiab cov txheej txheem.
Cov saum toj no yog cov lus qhia ntxaws ntxaws rau cov txheej txheem smelting ntawm aluminium bronze 10-3 alloy. Vim nws cov khoom zoo heev thiab kev tiv thaiv corrosion, Jiaxing Gurun aluminium bronze ZCuAl10Fe3 yog siv dav hauv kev tsim cov khoom siv zog, hnav-tiv taus qhov chaw xws li lub tes tsho tooj liab, cov vuas tooj liab, zawv zawg daim hlau, worm gears thiab txiv ntseej, thiab lwm yam.
