Poob-Wax Casting Ntawm Titanium Alloy Rau Tshuab ntxhua khaub ncaws

Ua ntej, lub siab -precision pwm yog ua raws li cov qauv tsim ntawm cov titanium alloy qhov yuav tsum tau rau lub tshuab ntxhua khaub ncaws. Tom qab ntawd, ciab yog rhuab thiab melted, ncuav rau hauv pwm, thiab tshem tawm tom qab txias. Qhov tseeb qhov tseeb thiab qhov zoo ntawm cov qauv siv quav ciab ncaj qha cuam tshuam rau qhov zoo ntawm qhov kawg titanium alloy qhov chaw. Yog li ntawd, cov txheej txheem yuav tsum nruj me ntsis tswj thaum lub sij hawm tsim khoom kom ntseeg tau tias qhov sib txawv ntawm qhov sib txawv ntawm cov qauv siv quav ciab yog nyob rau hauv qhov tsawg kawg nkaus thiab qhov chaw yog du thiab flawless.

Cov qauv siv quav ciab yog immersed nyob rau hauv ib txheej uas muaj cov ntaub ntawv refractory thiab binder, uniformly npog lub nto nrog ib txheej ntawm txheej. Tom qab ntawd, ib txheej ntawm xuab zeb yog sprinkled on to top. Cov txheej txheem no rov ua dua ob peb zaug los tsim lub plhaub ntawm ib qho tuab. Lub zog thiab permeability ntawm lub plhaub yog qhov tseem ceeb rau qhov zoo ntawm casting. Lub zog tsis txaus yuav ua rau lub plhaub pwm tawg thaum lub sij hawm casting, thaum tsis zoo permeability yuav cuam tshuam cov pa khiav thiab ua rau muaj qhov tsis xws li porosity.

Cov wax pwm nrog lub plhaub pwm yog muab tso rau hauv ib lub qhov cub dewaxing kettle los yog dej kub kom yaj cov quav ciab thiab cia nws ntws tawm ntawm lub plhaub pwm, ua ib kab noj hniav. Cov txheej txheem dewaxing yuav tsum ua kom tiav kev tshem tawm cov quav ciab; txwv tsis pub, residual ciab yuav ua teeb meem xws li porosity thiab inclusions thaum casting.

Lub plhaub pwm dewaxed tau muab tso rau hauv lub qhov cub hluav taws kub kom siab - kub hnyiab kom tshem tawm cov dej noo, organic teeb meem, thiab lwm yam impurities, thaum txhim kho lub zog thiab refractoriness ntawm lub plhaub pwm. Kev tua hluav taws kub thiab lub sijhawm yuav tsum tau tswj xyuas raws li cov khoom siv thiab tuab ntawm lub plhaub pwm kom ntseeg tau tias kev ua haujlwm zoo.

titanium alloy raw khoom yog muab tso rau hauv lub tshuab nqus tsev induction rauv rau melting. Thaum lub sij hawm melting txheej txheem, qhov kub thiab lub sij hawm yog nruj me ntsis tswj los xyuas kom meej uniform alloy muaj pes tsawg leeg. Thaum cov titanium alloy ncav cuag qhov tsim nyog qhov kub thiab txias, nws yog poured rau hauv kab noj hniav ntawm pwm plhaub nyob rau hauv lub tshuab nqus tsev los yog ib tug tiv thaiv cua. Lub pouring ceev thiab ntim kuj xav tau meej tswj kom tsis txhob muaj qhov tsis xws luag xws li tsis tiav pouring thiab txias kaw.

Tom qab pouring, cia lub titanium alloy kom txias lawm nyob rau hauv lub pwm. Qhov ntsuas cua txias cuam tshuam rau microstructure thiab cov khoom ntawm titanium alloy, yog li nws yuav tsum tau tswj kom tsim nyog raws li qhov yuav tsum tau ua ntawm ib feem. Tom qab txias, tshem tawm cov pwm uas siv cov txheej txheem los yog tshuaj, thiab ntxuav thiab zom cov khoom kom tshem tawm cov burrs, oxide nplai, thiab lwm yam impurities ntawm qhov chaw.

Cov titanium alloy uas huv si tau txais kev kho cua sov los txhim kho lawv cov microstructure thiab cov khoom, nce lub zog, hardness, thiab toughness. Kev kho deg, xws li electroplating thiab txau, kuj tseem yuav tsim nyog los txhim kho corrosion kuj thiab zoo nkauj ntawm qhov chaw. Thaum kawg, cov khoom tau raug tshuaj xyuas zoo, suav nrog kev kuaj xyuas qhov tseeb ntawm qhov tseeb, qhov zoo ntawm qhov chaw, thiab qhov tsis xws li sab hauv, kom ntseeg tau tias cov khoom ua tau raws li qhov yuav tsum tau siv rau hauv tshuab ntxhua khaub ncaws.
