Txheej txheem melting ntawm Aluminium 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, hlau txhuas, hlau, manganese, npib tsib xee, thiab lwm yam, thiab qhov saum npoo yuav tsum huv thiab tsis muaj roj stains.
Cov khoom siv rov ua dua tshiab yog cov khiav thiab cov khoom seem, uas yuav tsum tau ntxuav cov roj stains.
Kev npaj ntawm intermediate alloys:
10-3 intermediate alloys (Al-Fe alloys) yog ntxiv rau hauv qhov sib piv ntawm 10: 3, xav txog qhov zoo ntawm lub cub tawg tom qab hlawv.
Kev xaiv ntawm flux:
Kev xaiv cov slag tshem tawm 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.
Smelting khoom:
Kev tshuaj xyuas thiab kev npaj cov roj rauv thiab cov cuab yeej, nrog rau cov xwm txheej ntawm crucibles, ntxuav cov roj nozzles, preheating ntawm melting cov cuab yeej, thiab lwm yam.
Cov khoom siv pouring:
Kev tshuaj xyuas thiab kev saib xyuas cov tshuab centrifugal casting kom ntseeg tau tias cov khoom siv hluav taws xob, cov plhaub tiv thaiv, pwm fixtures, thiab lwm yam.
Kev npaj cov ladles, siv cov ntaub ntawv tshwj xeeb thiab cov proportions rau masonry.
Cov txheej txheem melting
Chemical composition range:
Aluminium (Al) 8.5-11%, hlau (Fe) 2.
Cov kauj ruam melting:
Xyuas cov roj rauv crucible thiab preheat 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 yaj, do kom tsim nyog thiab khaws qhov kub ntawm 1250 degree -1300 degree .
Ntxiv slag tshem tawm rau slag tshem tawm thiab ua kom sov li 10 feeb.
Nqa cov qauv rau kev txheeb xyuas qhov sib xyaw.
Ncuav cov castings thiab them sai sai rau qhov kub thiab txias ntawm castings nrog txawv phab ntsa thicknesses.
Pouring thiab txias:
nruj me ntsis tswj qhov hnyav ntawm cov kua tooj liab kom tsis txhob pov tseg.
Tom qab centrifugal pouring, cia cov castings txias ib txwm mus rau tsaus liab (500 degree -600 degree) thiab ces quench.
Cov kev ceev faj
Aluminium bronze alloys yog ib qho yooj yim los ua ke nrog oxygen los tsim oxides thaum lub sij hawm smelting txheej txheem, yog li stirring yuav tsum tau txo kom tsis txhob ua puas lub oxide zaj duab xis ntawm cov kua nto.
Qhov kub thiab tshuaj lom neeg muaj pes tsawg leeg yog nruj me ntsis tswj thaum lub sij hawm melting txheej txheem los xyuas kom meej lub zog ntawm cov alloy.
Cov kauj ruam pouring thiab txias yog qhov tseem ceeb rau cov khoom ntawm qhov kawg casting thiab yuav tsum tau ua raws li qhov ntsuas kub thiab txoj kev.
