Loj Iav Titanium Alloy Wax Poob Casting

Pwm tsim thiab tsim khoom: Raws li qhov loj me thiab cov qauv uas yuav tsum tau muaj ntawm cov iav loj, kev CAD software yog siv rau 3D qauv thiab pwm tsim. Xav txog tej yam xws li shrinkage tus nqi ntawm titanium alloy thaum lub sij hawm casting txheej txheem, tsim nyog yuav tsum tau ua rau lub iav loj. Siv cov khoom siv siab - precision machining, xws li CNC machining chaw, los tsim pwm. Pwm cov ntaub ntawv feem ntau yog ua los ntawm siab - cov cuab yeej zoo steel kom paub tseeb tias qhov tseeb thiab kev pabcuam lub neej ntawm pwm.

Wax molding: Ua kom sov cov khoom siv wax refined mus rau qhov ntsuas kub kom muab nws zoo fluidity. Txhaj cov khoom siv quav ciab rau hauv pwm ntawm ib lub siab los ntawm lub tshuab txhaj tshuaj, thiab tom qab cov khoom siv quav ciab txias thiab khov kho, tshem tawm cov quav pwm los ntawm pwm. Ua ntej trimming ntawm cov quav ciab pwm, tshem tawm cov khoom seem xws li burrs thiab burrs, los xyuas kom meej qhov zoo thiab qhov tseeb ntawm cov quav ciab pwm.

Txheej slurry: Raus lub npaj ciab pwm rau hauv ib tug tshwj xeeb npaj refractory slurry kom tusyees npog qhov chaw ntawm cov quav ciab pwm nrog ib txheej ntawm slurry. Slurry feem ntau yog tsim los ntawm cov ntaub ntawv refractory (xws li zircon xuab zeb, corundum hmoov, thiab lwm yam), binders (xws li iav dej, silica sol, thiab lwm yam), thiab cov khoom ntxiv. Tom qab txheej txheej tiav, sib npaug ntawm txheej txheej ntawm cov xuab zeb refractory nrog cov khoom me me rau ntawm qhov chaw ntawm cov quav ciab pwm kom muaj zog thiab tuab ntawm lub plhaub.

Ntau txheej txheej txheej thiab ziab: Rov ua cov txheej txheem ntawm txheej slurry thiab xuab zeb, thiab feem ntau yuav tsum tau 4-8 txheej txheej txheej ua haujlwm raws li qhov loj thiab qhov nyuaj ntawm lub zog loj. Tom qab txhua txheej txheej, kev kho kom qhuav txaus yuav tsum tau nqa tawm kom ntseeg tau tias lub plhaub zoo. Cov txheej txheem ziab yog feem ntau yog ua nyob rau hauv ib qho chaw qhuav, nrog rau kev tswj kub, av noo, thiab cua txias kom tsis txhob muaj qhov tsis xws luag xws li tawg hauv lub plhaub.

Dewaxing: Muab ntau- txheej txheej coated thiab qhuav plhaub rau hauv cov khoom siv dewaxing, thiab siv txoj hauv kev xws li chav dewaxing lossis dej kub dewaxing kom yaj cov quav pwm thiab ntws tawm ntawm lub plhaub, yog li tsim cov kab noj hniav uas zoo ib yam li cov iav loj hauv lub plhaub. Cov txheej txheem dewaxing yuav tsum tswj qhov kub thiab txias thiab lub sij hawm kom ntseeg tau tias cov pwm siv quav ciab yog yaj tag thiab tawm mus, thaum tsis txhob muaj kev puas tsuaj rau lub plhaub.

O-plhaub roasting: Muab lub plhaub dewaxed rau hauv siab -kub roasting rauv rau roasting. Lub hom phiaj ntawm roasting yog tshem tawm cov khoom seem thiab cov av noo hauv lub plhaub, thiab txhim kho lub zog thiab hluav taws kub ntawm lub plhaub. Lub calcination kub yog feem ntau ntawm 900-1100 degree, thiab lub sij hawm calcination nyob ntawm lub thickness thiab cov khoom ntawm lub plhaub, feem ntau 2-6 teev.

Titanium alloy melting: Cov ntaub ntawv zoo titanium alloy raw khoom raug xaiv thiab raug faib ua raws li cov qauv tsim tshuaj. Advanced melting khoom xws li lub tshuab nqus tsev consumable arc furnaces los yog plasma beam melting furnaces yog siv rau melting. Thaum lub sij hawm melting txheej txheem, kev tswj nruj yog siv tshaj qhov tsis xws li melting kub, lub sij hawm, thiab lub tshuab nqus tsev kawm ntawv kom paub meej tias cov tshuaj muaj pes tsawg leeg ntawm titanium alloy yog ib yam thiab cov impurity cov ntsiab lus raws li qhov yuav tsum tau.

Pouring: Ceev nrooj ncuav cov kua titanium alloy melted rau hauv lub plhaub preheated ntawm qhov kub thiab txias. Cov txheej txheem pouring yuav tsum tau ceev kom du thiab ceev kom tsis txhob muaj qhov tsis xws luag xws li gas entrapment thiab slag inclusion. Txhawm rau kom ntseeg tau tias qhov zoo ntawm cov iav loj, txoj hauv kev xws li lub ntiajteb txawj nqus casting lossis qis - siv lub zog casting, thiab kev co tsim nyog tuaj yeem siv tau thaum lub sij hawm casting txheej txheem los txhawb kev txhaws thiab tso tawm ntawm titanium alloy kua.

Ntxuav lub plhaub: Tom qab lub tshuab ua kom txias, cov cuab yeej tu lossis tshuaj ntxuav cov txheej txheem yog siv los tshem tawm cov pwm plhaub. Kev tu neeg kho tshuab feem ntau yog siv lub tshuab ntxhua khaub ncaws los yog cov khoom siv sandblasting, thaum kev ntxuav cov tshuaj muaj kev cuam tshuam cov casting hauv cov tshuaj tshwj xeeb kom yaj cov pwm.

Kev kho cua sov: Kev kho cua sov yog siv rau cov iav loj tom qab ntxuav lub plhaub los txhim kho lawv cov microstructure thiab kev ua haujlwm. Cov txheej txheem kev kho cua sov uas muaj xws li annealing, quenching, tempering, thiab lwm yam. Xaiv cov txheej txheem kev kho cua sov uas tsim nyog raws li cov txheej txheem ntawm titanium alloy thiab cov kev cai siv iav los txhim kho lub zog, hardness, thiab toughness ntawm cov iav.

Mechanical processing and testing: Mechanical processing of large gears after heating treatment, xws li tig, milling, sib tsoo, thiab lwm yam, kom ua tiav qhov yuav tsum tau muaj qhov tseeb thiab qhov chaw roughness hauv kev tsim. Cov cuab yeej ntsuas qib siab xws li kev sib koom tes ntsuas cov cuab yeej thiab cov ntsuas qhov tsis zoo yog siv los tshuaj xyuas qhov tseeb ntawm qhov tseeb, sab hauv zoo, thiab qhov zoo ntawm cov iav, kom ntseeg tau tias lawv ua tau raws li cov qauv zoo.
